From: mibrahim@rcsuna.gmr.com (Mamdouh Ibrahim ) Subject: CONF: OOPSLA '93 Workshops Advanced Program Date: Thu, 3 Jun 1993 12:20:53 GMT Organization: GM Research Labs, Warren, MI Crossposted from news.announce.conferences Call for Participation OOPSLA '93 Workshops Program Workshops are a means for experts to meet and discuss issues with a selected focus in an atmosphere which fosters the active exchange of ideas among researchers and practitioners. They provide a forum for the thrust-and-parry of scientific discourse. Workshops also provide an opportunity for representatives of a research community to coordinate efforts and establish collective plans of action. To ensure a sufficiently small group for effective interaction, workshop attendance is controlled with prospective attendees submitting a short position paper outlining their opinions on an aspect of the workshop topic. Participants are chosen based on the relevance of their position paper to the workshop theme. Workshop presentations are at the discretion of the workshop organizers but all attendees are expected to join in the debate with ample time allotted for general discussion. After the workshop, the organizer(s) will be responsible for reporting to the OOP community via an article in the Proceedings Addendum. Papers for the workshops are due by July 30, 1993 and invitations will be issued on or before August 20, 1993. The submission addresses and requirements depend on the workshop; see information at the end of each workshop description. Workshop participants must register for the conference (at least for one day) and they are encourage to preregister as soon as possible. This year, conference identification badges will reflect workshop registration similar to the conference and tutorial registration. Only those with valid workshop registration will be admitted to workshop sessions and the workshop reception. Mamdouh H.

C. Ting, University of Connecticut This is a workshop on integrating object-oriented technology and security technology. The workshop will address two aspects. First one will be on incorporating security into object-oriented systems to produce secure object-oriented systems. The second aspect will be on the use of object-oriented design and modeling techniques for designing secure applications. The participants of this workshop will include members of the security community, object-oriented community, vendors of secure systems, object-oriented systems, and CASE products, members of the DoD and other Government agencies, researchers and practitioners of secure systems, object-oriented systems, and CASE tools. Issues to be Discussed Mandatory Security: For many C4I applications, it is important to provide mandatory security. Consequently, multilevel secure object-oriented systems (MLS/OOSs) are needed in order to ensure that users cleared to different security levels access and share a database with data at different security levels in such a way that they obtain only the data classified at or below their level. Discretionary Security: The workshop will also discuss discretionary security in object-oriented systems. With discretionary security, users are granted access to the objects based on their identification. Object-Oriented Approach to Designing Secure Database Applications: Object-oriented technology is also being applied to design secure applications. Object-oriented modeling and analysis techniques are showing much promise for designing secure applications. Requirements for Participation Position papers between 3- 5 pages on relating security and object-oriented systems should be submitted to Dr. Bhavani Thuraisingham by July 30, 1993. Papers will be reviewed by the worshop organizers and acceptance/rejection will be based on relevance to the workshop and the quality of the paper. Authors will be notified of the status by August 20, 1993. The final version will be due by August 31, 1993. The accepted papers will be published in the Proceedings and distributed at the workshop. Papers will be selected from this list to be presented at the workshop. In addition to presentations, the workshop will also include discussion sessions. The final minutes of the workshop will be published in the addendum to the Proceedings of the OOPSLA Conference.

Watson Research Center, USA Ashok Malhotra, IBM T.J. Watson Research Center, USA Vicki de Mey, University of Geneva, Switzerland. As object-oriented systems become larger and more complex, it becomes increasingly important to leverage audio and visual techniques in tools for program understanding, debugging, and tuning. When profiling a given OO system, visual techniques become valuable, even indispensable, when determining clusters of instances or classes that appear to consume the most processing power. The majority of the relationships between object instances are naturally expressed in a visual fashion. Therefore, it seems logical to use visual techniques for monitoring and debugging OO systems. Sound is also quite useful since it can have a wider information bandwidth than text and, at the very least, it can get someone's attention. Other techniques, including virtual reality or sensory inputs other than visual or audio, also have potential. This workshop will bring together people that have developed advanced techniques other than textual to enhance the understanding of an OO system, or to improve its execution or correctness. This might include displaying networks of object instances, or maybe customized representations of objects that are normally difficult to trace as they are manipulated during the execution of the system. Discussions should be started to gain ideas about how to extend existing object browsers and debuggers to equip them with more powerful visualization techniques. The different techniques will be presented to the other attendees and their individual applicability, strengths, and limitations will be discussed. Requirements for attendance All participants should submit a short (2 page) position papers to the workshop organizers. The paper should briefly describe your specific techniques and how they enhance the understanding of OO systems or contribute in profiling or debugging them. Papers must be submitted by July 30, 1993. Participants will be selected and notified August 15, 1993. Position papers MUST be submitted by email, in ASCII. It is highly recommended that position papers be accompanied by relevant paper references. The distribution of these papers is left to the attendees. Contact: Ashok Malhotra IBM T.J.

Organizers: Kendall L. White, Workstation Engineering Center (WSEC), MITRE Corp. Elaine S. Ward, Software Engineering Center (SWEC), MITRE Corp. John D. Sheffler, Center for Advanced Aviation System Development (CAASD), MITRE Corp. Given the current climate of declining federal budgets, it is necessary to see the cost/benefit associated with utilizing OOT. Many Information System managers and developers have the perception that OOT is not mature enough for mainstream use (i.e., Fortune 500 Enterprises, large scale government acquisitions/procurements, etc.) and are therefore unwilling to take the risks associated with implementing new technologies. This belief is easily supported when reviewing the number of systems developed using OOT vs. more traditional technologies. It has also been observed that relational technologies have taken at least 15 years to mature. Goals of the Workshop: goals of this workshop are to address the following issues: - Is OOT mature enough for Information Systems developments now? - What is needed for OOT to gain wider acceptance? - Is there a process to support the inclusion of OOT Information Systems development? - Are there measurable benefits resulting from the use of OOT in Information Systems developments that might offset the perceived risks? - What case studies of OOT implementations represent success stories for others to follow? Focus of the Workshop: The focus of this workshop is to provide a forum for software professionals and government officials to discuss how Object-Oriented Technology (OOT) can be applied to Information Systems development. This forum will assess the current state of the art of OOT within the Government and the private sector. The focus areas to be addressed include but are not limited to: Strategic Planning, Business Process Reengineering, Requirements Analysis, Software and Database Design, Software and Database Implementation, Test and Evaluation, and Reuse and Maintenance. The result of the workshop will be an assessment of the current state of the art of OOT as it relates to Mainstream Information Systems in terms of the strengths, weaknesses, and recommendations to turn weaknesses into strengths. for Attendance: The intended audience for this forum are those individuals involved in acquisitions, procurements, and development of Information Systems including government personnel, contractors, and consultants. Interested parties must submit a white paper of 2-5 pages on any of the previously mentioned topics or other relevant areas of interest before July 30, 1993. Accepted participants will be notified by August 20, 1993. Submissions to the workshop may be sent electronically (preferred) or via regular postal services to: Contact: Kendall L.

To understand an enterprise, make its components reusable and semantically interoperable, precise specifications of behavioral semantics are essential. Current specifications usually emphasize only signatures, with semantics described informally and incompletely. Further, as objects do not exist in isolation, modeling an enterprise involves modeling the collective behavior of objects that make up the enterprise. In particular, modelers are confronted with the dual problems of refining a required functionality using the collective behavior of partially-specified (or yet to be identified) objects (decomposition), and reusing the collective behaviors of fully-specified objects to achieve a desired functionality (aggregation). Focus: to explore behavioral modeling concepts, especially modeling the collective behavior of objects (using declarative constructs), and behavioral abstraction and refinement approaches for aggregation and decomposition. The workshop IS NOT about comparing modeling methodologies; neither is it an opinion forum. Some topics of particular interest include formal specification of behavioral semantics (using notations like Z), and standardization of specifications of reusable information technology components. Goals: A cross-fertilization of formal and heuristic/informal specification approaches, and an outline of open practical and theoretical questions that would advance the state of the art and the practice. Requirements for attendance: A 3-4 page position paper (preferably by email) outlining behavioral specification approaches and experiences using specific approaches to address the aforementioned problems must be submitted before July 30, 1993. Notification of acceptance or rejection will be mailed before August 20, 1993.

Cummins, EDS Artificial Intelligence Services Roman Cunis, MAZ GmbH, Germany Andreas Paepcke, Stanford University The purpose of this workshop is to explore extensions to the object- oriented paradigm that make it more robust or incorporate other paradigms. Extensions have been explored in existing languages or have been demonstrated in experimental languages. The development of object-oriented languages continues, object-oriented COBOL is a significant example. Hopefully the information exchanged in this workshop will influence the design of the next generation of object-oriented languages. Goals of the Workshop This workshop is a continuation, in part, of the workshop of the OOPSLA'92 workshop entitled "Object-Oriented Programming Languages: The Next Generation." The format will differ. This workshop will be organized into discussion groups and will spend less time on presentations to the entire group. Participants will be asked to identify topics they would like to discuss in a group. The number of discussion groups, and thus the number of topics will depend upon the number of participants. Issues Below are some possible topics: - Constraint-based reasoning - Logic programming - Data-driven programming - Rule-based programming - Instance specialization - Dynamic reclassification - Uncertainty - Multiple worlds and hypothetical reasoning - Case-based reasoning - Functional programming - Semantic networks - Machine learning Requirements for Attendance Participants from last year's workshop on "Object-Oriented Programming Languages: The Next Generation" are invited to attend again this year. Participants are expected to have participated in the development or in-depth application and evaluation of a particular language. They are expected to be able to contribute to discussion on the nature and value of distinct language features. Potential participants are required to submit 5 copies of a position paper addressing the following topics: - The submittor's experience - Proposed language features/capabilities - Topics of interest for discussion The deadline for submission is July 30, 1993 and acceptance or rejection notifications will be issued before August 20, 1993.

Bilow, Tektronix, Network Displays Division Dennis de Champeaux, Faure Inc Karl Freburger, Knowledge Systems Corporation Doug Lea, SUNY Oswego & NY CASE Center Despite the growing acceptance of the OO paradigm, we must acknowledge that OO is not yet a mature engineering discipline. Development process and the metrics required to assess quality, reliability, productivity and cost are, at best, under-defined. Advances in the OO development process and its associated metrics are urgently needed. Goals of the workshop The workshop aims at advancing the state of the art in such areas as: - The engineering activities within the OO analysis and design process. - Product and process metrics that foster the assessment of quality, reliability, productivity, and cost throughout the product lifecycle. - Measurement, estimation, and management of the OO development process. Focus of the workshop This workshop seeks to address the following issues: - Estimating the effort required for a project with respect to OO analysis, design, implementation, test, and maintenance. - Objectively tracking progress of an OO development activity. - The impact of OO CASE tools on effort estimation and development process. - The dependency relationships between potential OO metrics and the specifics of a particular development method. Requirements for attendance This workshop will be of interest to software quality researchers, object- oriented methodologists, software metricians, practitioners with interests in reuse, frameworks, design, analysis, and programming; and those interested in the management of object-oriented development projects. Potential attendees should submit a 2-3 page position or experience report, in ASCII text format, to Steve Bilow, no later than July 30, 1993, and notification of acceptance or rejection will be mailed on or before August 20, 1993.

Russel Winder, University College London At OOPSLA '92, this workshop examined the tension between iterative design methods and the stability and progress tracking valued by most development cultures. This year's workshop will discuss these issues in the context of established and emerging industry standards for software development process. Such standards include the SEI Capability Maturity Model (CMM), the ISO 9000 series, STD 2167A, and IPSE2.5. Goals of the workshop Participants will discuss how existing methods support the object paradigm through iteration and other key characteristics. Evolution paths will be discussed for the object paradigm and current-generation development process frameworks to improve their ability to meet each others' needs. Focus and issues We will focus on two or three established process standards that reflect material submitted in position papers. Participants will draw on each others' experience to develop consensus on the suitability of those standards to object-oriented development. Requirements for attendance Prospective participants must submit short (1-3 page) position papers to the workshop organizers by July 30, 1993. Participants will be chosen on the basis of the suitability of these papers. Participants will be selected and notified by August 20, 1993. Members of the software development process community are particularly encouraged to participate.

Sloane, SunPro Theodore C. Goldstein, Sun Microsystems Laboratories Inc. Michael S. Ball, Taumetric Corporation Andrew Palay, Silicon Graphics Inc. As object-oriented programming has become more pervasive in the development of large software systems it has become clear that we must be able to support compatible changes to class definitions and implementations without having to rebuild the entire system. Without this ability it will be impossible to build real systems that use shared libraries or on-demand dynamic loading. Further, without this ability there are significant costs in programmer productivity because of long turnaround time on compilations, and in lowered quality because system designers choose to work around problems in the kernel of systems rather than impose the cost of recmpilation on clients. As OOP has moved out into the real world, and has been adopted in large scale systems (including most of the next generation of operating systems and platform software), these issues have come to the fore as a challenge to OO languages. Without solutions, the benefits of software reuse will remain ungained, and in the longer term the commitment to OOP itself will be questioned. Focus and List of Issues This workshop will focus on the question of how we design object-oriented languages and their runtime systems to support making compatible changes to class definitions. This includes the examination of already existing languages and how we can support changes to class definitions within the the constraints of those languages. Topics and issues which will be relevant include : - Evolvable classes and types - "Shrink-wrapped" objects - Application Binary Interfaces - Shared libraries and dynamic linking - Versioning and narrowing - Type conformance - Delegation - Schema evolution - Object Request Brokers and Object Models - Interface definition languages - Metalevel data - Incremental compilation - Software Reuse Requirements for Attendance Atendance at the workshop will be by invitation, after submission of a position paper. The organizers will select eight speakers to make presentations based on the content of their position papers, and on covering a diversity of viewpoints relevent to the workshop focus. (Three of these presentations will be scheduled for 45 minutes duration, and five for 20 minutes.) In addition to the presentations, there will be substantial time for discussion. Deadline for submission is July 30, 1993 and authors of accepted papers will be notified by August 20, 1993. Contact: Alan D.

Mark Mayfield, Object International, Inc. Bruce Anderson, Electronic Systems Engineering, University of Essex This workshop will build on the successful Architecture Handbook and Patterns workshops held at previous OOPSLA conferences. The goal of this workshop is to identify and describe practical patterns for object-oriented development. A pattern is a building block. It consists of a small number of interconnected classes and objects; it's a grouping that one can see again and again. Patterns can provide an overall framework, a useful structuring or a pervasive style. When someone describes a pattern, one often uses a real-world analogy to explain it---and remember it. Developers use patterns to communicate expertise and accelerate object-oriented development. Participants for this workshop should have actual experience in building object-oriented systems. Participants should also want to improve their practice through a deeper technical appreciation of patterns. In the workshop, participants will further develop and extend the notion of patterns for object-oriented development. Beginning from the material written beforehand by attendees, participants will work mostly in small groups, doing a lot of writing and discussing, and using accelerated learning techniques such as brainstorming and guided visualization to speed the participants along. By the end of the workshop, the participants will produce an OOPSLA'93 Pattern Book, containing these sections: - Definitions - Standard Format - Patterns (15-20 examples) - Observations - Recommendations Potential participants should prepare and submit the following: - A pattern description Each potential participant must find a pattern from their experience and describe it in a pattern template provided by the organizers. Optionally, potential participants may submit a paper on patterns, their use in other fields, and their application in software development. - A biographical sketch (200-250 words) Potential participants should contact the organizers for the pattern template, some examples, and supporting materials. The deadline for position papers is July 30, 1993. Authors will be notified of acceptance by August 20, 1993. Copies of position papers will be distributed by 1 September 1993.

The community is making interesting progress on memory management issues all the time. This workshop follows in the tradition of similar previous workshops help at OOPSLA '90 and '91 and the International Workshop on Memory Management held in France in 1992. Goals: We will offer a forum for presentation and discussion of recent work, current developments, and the most promising directions for the future. The workshop is intended for researchers and implementers active in the field. Focus and issues: Techniques for memory management and garbage collection in object-oriented systems, including support in programming languages and implementations, in persistent object stores and object-oriented databases, in real-time systems, and in distributed systems. Especially welcome are reports on performance measurement and comparisons; i.e., we would like quantitative evaluation to be one of the emergent themes of the workshop (but not to the exclusion of new ideas not yet reduced to implementation and measurement). Requirements for attendance: Attendance will be by invitation only. Interested parties should submit a 2 to 5 page position paper and indicate whether they desire to make a presentation, and if so, whether they prefer to make a short (10 minute) or long (20 minute) presentation. We will make final versions of positions papers of attendees available to the other attendees and publicly on the Internet. Attendance will be limited to 30 to 40 attendees and we reserve the right to limit the number of authors attending in conjunction with each invitation. The deadline for submission is July 30, 1993 and invitations will be issued before August 20, 1993.

V. Kale, University of Illinois (Co-ordinator) Ian Angus, Boeing Computer Services Andrew Chien, University of Illinois Akinori Yonezawa, University of Tokyo Concurrent object oriented approaches have many advantages for programming parallel systems. However, a major impediment to its widespread acceptance for parallel programming is the perception that implementations of concurrent object-oriented languages are inefficient (particularly compared to Fortran). The purpose of the workshop is to examine the efficiency of existing concurrent object-oriented language implementations, discuss techniques for improving the efficiency of such implementations, and identify the challenges in reaching parity in efficiency. An important goal of the workshop is to facilitate communication amongst researchers working in distinct communities, including applications and implementations. The workshop will focus on all aspects of efficient implementation of concurrent object-oriented programs. An incomplete list of these topics include: - Compilation techniques (static analysis and optimization) - Supporting data parallel computations - Run time issues (load balancing, scheduling, and message driven execution) - Efficiency problems observed in Practice Participants who wish to make a presentation are required to submit a short position paper (2-5 pages). The organizers will select from the submissions based on their relevance to the workshop focus, technical quality, and time available. Electronic mail submissions (to oopsla-concobjs@cs.uiuc.edu) are enouraged. Other participants must also submit a position statement (1 page) and will be selected based on the space available. Submission deadline is July 30,1993 and authors of acceptance papers will be notified by August 20, 1993. Contact: Professor L. V.

McGregor, Object Technology Group, Clemson University Peter Dimitrious, Object-Oriented Technology Center,IBM David A. Sykes, Software Architects, Clemson, SC The testing activity in object-oriented software development has not received as much attention as other activities in the development process. Many issues have been raised, but few have been completely or satisfactorily addressed. For example, how do polymorphism and dynamic binding affect the selection and execution of test cases? How should test plans be structured to accommodate an iterative incremental process model? The purpose of this workshop is to provide a forum for discussion of these and other issues related to testing object-oriented software systems, the presentation of status reports from research projects and experience reports on test plans developed for actual systems, and the development of agendas for research and development activities related to testing issues. The workshop will begin with selected position papers being presented. The papers will be selected to provide a balance between research and practical experience. Based on the interests represented in the position papers, the organizing committee will form working groups. Each group will address a set of related issues. The report of the group will focus on the status of knowledge, research, and practice in their particular area. Each group will report to the workshop in the afternoon with a synopsis of their discussions and a suggested list of research and development activities for that area. The compendium of these reports and the submitted position papers will be the primary output of the workshop. A secondary result will be the establishment of a community of interested individuals. Workshop Participation: Persons wishing to participate in the workshop should submit a short position paper to the organizing committee via the contact person. The paper should address a specific aspect of the testing process or outline a specific testing algorithm. Two or three of the papers will be selected for presentation at the beginning of the workshop. All papers will be considered for publication. Submitted papers must be received before July 30, 1993, and notification of acceptance or rejection will be mailed on or before August 20, 1993. Contact: John D.

Design trade-offs are often necessitated by performance requirements, limited market-windows, deployment costs and long-term maintenance issues. These systems cannot be re-engineered overnight, but require transition strategies where old and new components must coexist and interact. Participants will exchange experiences (both successes and failures) and develop a consensus on the activities required to bridge the transition between current and re-engineered systems (chaos to order). Consensus will be achieved through the collaborative efforts of all participants. Workshop activities will be moderated by an experienced group facilitator using the techniques employed at the successful OOPSLA'92 workshop "Team Approaches to Object-Oriented Design". Position papers should indicate participants' experience with object-oriented design techniques, the size of their current system (design/code bulk and team size), their design tools, and design processes. To begin the consensus building process, participants are also expected to address the following questions in their position paper: - Where are you going? How would you personally characterize successful re-engineering? - Where have you been? What design-tradeoffs have been effective or ineffective in your organization? - How will you get there? What steps have you already identified in order to begin re-engineering your system? Participants will be selected on the basis of position papers (500-1,500 words/2-5 pages) submitted by email. Please include a brief biography at the end of your position paper. Deadline for submission is July 30, 1993, and acceptance or rejection will be mailed on or before August 20, 1993.

Mary E. S. Loomis, PH.D., Versant Object Technology. Allen Otis, Servio Corporation T. Lougenia Anderson "Lougie", PH.D., Sequent Oris Friesen, Ph.D., M.S. AZ05-H32 The need to integrate run-time objects with data residing in object oriented databases, non- object oriented databases and legacy systems poses significant challenges that must be overcome. This workshop will gather individuals participating in such systems development/integration for examination of relevant issues. The goal of the workshop is to identify the dominant technical issues that should be addressed by vendors and standards for such systems integration. Topics posing integration challenges included: Mapping and storing objects in non- object databases and object databases simultaneously. Retaining object integrity within distributed, and heterogeneous databases. Object oriented language interfaces for object, relational and other databases. Object querying in heterogeneous databases. Distributed transaction management for object based heterogeneous environments. Encapsulating legacy systems for integration with object based systems. Interested parties must have participated (or are currently participating) in the development of a system employing related topics. Consideration will be made to papers indicating future challenges envisioned. Participants are expected to contribute to discussion on the challenges and solutions relevant to the design of such systems. Participation will be by invitation only and is based on the acceptance of a relevant position paper. Papers should be no more than 4 pages in length. Acceptance will be based on the relevance of the material to workshop objectives and on architectural integrity of the persistency techniques and tools implemented. Potential participants are required to mail 5 copies of a position paper by July 30, 1993, and acceptance or rejection notices will be mailed on or before August 20, 1993.

A reflective object-oriented language allows a running program to look at or change the objects out of which it is built. Reflection can extend the reach of a programming system inward into the definition of the language itself, downward into its implementation, and outward into realms currently considered the provinces of operating systems, programming environments and database systems.Object-oriented reflective architectures can allow issues that have heretofore been dealt with in ad hoc, extra-linguistic fashions, such as debugging and tracing, distributed computation, concurrency, and persistence to be dealt with in a consistent manner. This workshop will be the fourth in a series, and follows workshops that were held at ECOOP/OOPSLA '90 in Ottawa, OOPSLA '91 in Phoenix, and ECOOP '92 in Utrecht. The workshop will be organized into several sessions, each of which will be comprised of presentations and moderated discussions. Possible topics include: - Reflective theory, definitions and terminology - Metalevel architectures for reflective languages and systems - The efficient implementation of reflective facilities - Reflection in concurrent and distributed systems - How reflection can bridge the gap between traditional languages and system-wide extralinguistic object models Potential participants will be asked to submit a position paper of two or more pages. These papers may be extended abstracts of original work in progress, or position statements that outline the author's interest in or opinions on one or more issues in the area. We intend to make copies of all the accepted position papers available to all the participants prior to the workshop. Submission deadline is July 30, 1993, and notification of acceptance or rejection will be mailed on or before August 20, 1993. Electronic submissions are encouraged.

The goals of this workshop are to bring together a variety of insights and experiences in visual OOP by sharing recent and emerging work; discussing problems and solutions; and participating in an active exchange of ideas. Sample topics include (but are not limited to): - Programming Language Issues for Visual OOPs (approaches to scope, inheritance, efficiency, ...) - Innovation and Non-Traditional Approaches to OOP via Visual Techniques (constraints, declarative approaches, ...) - Visual Environments for Textual OOPs - Lessons Learned in the Trenches: Experience Papers on Visual OOP Attendees must have participated in in-depth research or development work involving a visual programming language or visual programming environment related to OOP. Participation in the workshop will be by invitation only and is based on the acceptance of an extended abstract and a brief (1-2 pages) biographical sketch summarizing current activities, related publications, current position, and affiliation. A book containing full versions of some of the papers (refereed) is planned. Potential participants are required to submit 5 copies of an extended abstract and biographical sketch to the contact person by July 30, 1993. Acceptance or rejection notices will be issued on or before August 20, 1993.

To facilitate this adoption, a number of organizations have set up a corporate "object technology center." This workshop will provide the first forum for members of such corporate groups to discuss and exchange information on these issues. Goals: A specific goal of the workshop is to identify the kinds of collaboration and information exchange that could benefit all participants. For example, all organizations adopting OOT have to solve issues relative to testing OO systems. Collaboration in the development of testing algorithms and tools could facilitate the effective adoption of OOT for all involved. Participants will be asked to identify the areas of most pressing need to their organization. An attempt will be made to develop a prioritized agenda and workplan for solving these issues. Focus and list of issues: We list several issues below, to give potential participants an indication of the focus of the workshop. - How should a corporate object center be structured, and what activities should it undertake to most effectively help an organization in the transition to OOT? What is the relative benefit of these activities. For example, does the creation of design handbooks have a higher leverage than the evaluation of tools and environments? - How to change the culture and literacy of a development group enough to open the group to a move to OOT? For example, how do help developers move from a code centered approach to a design centered approach? - How to change existing corporate processes, measurements, funding policies, etc. to allow OOT to function effectively? What is the minimum set of changes required? Is there an OOT maturity model and can we identify the kinds of changes needed to move from one level to the next. What is the minimum time an organization must remain on one level before it can safely move to the next? - How to effectively infuse OO expertise into an organization. How do we grow OO expertise in-house, and how do we most effectively utilize outside consulting. Specifically what role should the corporate object center play in this. Requirements for attendance: Participants should be members of a corporate "object center." Organizations considering the establishment of such a center may send a person to this workshop on a space available basis. Participants are required to submit a position paper. Two types of papers are sought. - Papers that summarize corporate object center experiences. These papers should indicate what has worked and what hasn't. They should also indicate what the most pressing current needs are for their organization and what possible areas of collaboration exist. - Papers on a specific issue faced by corporate object centers. These papers will focus on a topic from the above list or a related issue. Deadline for submission is July 30, 1993 and notification of acceptance or rejection will be mailed before August 20, 1993.

Clyde, SWC & Associates Bruce A. Conrad, WordPerfect Corporation David W. Embley, Brigham Young University Stephen W. Liddle, Brigham Young University Scott N. Woodfield, Brigham Young University Barry D. Kurtz, Hewlett-Packard Minor and major variations in concepts and terms for object-oriented models abound. The concepts and terms are maturing to the point that it may now be possible to resolve differences and come to agreement. Furthermore, suitable approaches to formalizing these ideas are beginning to appear, which may help solidify agreement. Goals: In this workshop we wish to address three fundamental issues: - What are the core concepts of the object model? - How have people defined these concepts? - What are suitable approaches to formalizing these concepts? Core concepts may include, but are not limited to: object, class, encapsulation, inheritance, relationships among objects, role, state, object behavior, messages, interactions among objects, concurrency, persistence, versions, abstraction, views. In addition to intuitively understanding core object-model concepts, we seek to explore approaches to formalizing them. Focus: This workshop focuses on model concepts. In particular, issues concerning notation and methodology will not be discussed. Instead, we wish to provide a forum where members of the object community can compare and evaluate similar, subtly different, and opposing ideas underlying object-model concepts. Requirements for Attendance: Submit a position paper (max 2,000 words) by July 30, 1993, preferably by e-mail. Notification of acceptance will be sent by August 20, 1993. Contact: David W.
