At PDC a mere two weeks away attendees will get a first-hand look at OLSO through a CTP. Three technologies that will make up OSLO will be in it:

A language – codenamed “M” – that helps people create and use textual domain-specific languages (DSLs) and data models
A relational repository – that makes models available to both tools and platform components
A tool – codenamed “Quadrant” – that helps people define and interact with models in a rich and visual manner

So some more codename’s, but at least I know what to expect. This CTP will probably reside on a 160 Gb external hard disk every attendee will receive.
