The 8th Workshop on Domain-Specific Modeling
Steven Kelly, Ph.D. - MetaCase
20 October 2008
There is increased awareness within the modeling arena of the need for a central repository of system description information. This is brought on by a growing recognition that only with a strong central repository can modeling tools be integrated, cope with large projects, provide full life-cycle support, produce complete documentation, perform system-wide validation and verification, and adequately control a project. In examining the various approaches chosen or proposed by various tool providers and users vendors, it is apparent that for many a model repository is nothing more than an off-the-shelf version control system into which XML files are saved. However, as this talk will demonstrate, current version control systems and XML cannot be successfully employed as a model repository.
This keynote is homage to Richard J. Welke's article from 1988, "The CASE Repository: More than another database application", which laid out the requirements for a model repository and meta-metamodel. The article is as relevant today as it was 20 years ago -- in fact, with the increased interest and usage of modeling, it is even more relevant now.

Ever present on the program committee of the OOPSLA workshops on Domain-Specific Modeling, he co-organized the first workshop in 2001. He is author of a book and over 20 articles, most recently in journals such as Dr. Dobb's and ObjektSpektrum, and is a member of the editorial board for the Journal of Database Management. He has an M.A. (Hons.) in Mathematics and Computer Science from the University of Cambridge, and a Ph.D. from the University of Jyväskylä. His computer education began with machine code, Assembler and BASIC, and came to rest in Smalltalk. Outside of work, he has co-authored the first grammar of the Kenyan Orma language, and is a soccer player in the Finnish Third Division.
