0??? tools: perhaps this is a phase all such
tools must go through.
Early development of MetaEdit+ concentrated on laying a strong architectural
foundation, based on the experiences with MetaEdit and building on earlier work in
QuickSpec and PSL/PSA. Initial development took place in the MetaPHOR research
group, which had been formed at the university in 1987. The company, MetaCase, was
founded in 1991, and development efforts progressively shifted from the university to
the company. This move was completed when the core developers ?¬?nished their
doctorates in 1998. While much has happened since then, the academic history of the
early days does mean that there are around 30 theses and 150 articles documenting the
initial versions of MetaEdit+ (e.g., Kelly et al., 1996) and the ideas behind it
(e.g., Tolvanen, 1998).
MetaEdit+ is at level 6 in our scale of tool evolution: metamodeling and modeling
take place in the same integrated environment, running as a single or multiuser system
on any of today??™s major platforms.With version 4.5 released in 2006, it ful?¬?lls all the
criteria we have identi?¬?ed above as desirable for a DSM environment??”time to
identify some new requirements! Humor aside, given the greater time we have had to
evolve MetaEdit+, it would be surprising if we had not been able to develop it to ful?¬?ll
what we see as necessary from our experience and understanding.
