Interesting interview, especially the piece about Excel as a (sort-of) language workbench. I'm gathering that many in the DSL forefront see the future of programming as writing DSLs for specific platforms (i.e. Oslo), frameworks (i.e. Rails), or the actual language used for writing the code in a specific business domain (i.e. DDD). I find that an interesting proposition, though I can only imagine the number of DSLs we'll see as most programmers (or at least I do) like digging into the nuts and bolts and making things fit their own mindset.
Martin Fowler, on C9?
Bloody awesome!
We want more
My criticism of Oslo would be that it focuses too much on data and not enough on behavior. I think that's what makes it "19th century".
On the other hand, a focus on data sells, especially in the Microsoft space. You just have to be prepared to be snubbed by the "intellectuals", who admittedly don't represent a huge market segment.
Another problem I have with Oslo is its use of a database as an artifact repository; something like TFS with version control would seem to be more of a fit. A question: why don't you tell us to put our code in databases? Is the DSL any different?
It is my understanding that the DSLs, textual information, etc. are just text and therefore are more than suited to being housed within something like TFS. I think that the purpose of the repository being within SQL Server is because the creation of the structure is only half of the story. The other half, is the runtime consumption of the information stored witin that repository and even updating, inserting information into the database. It is probably more of a mental leap to think in terms of moving from the model being a design-time artifact to a runtime one in the form of model-supported or model-driven applications.
Hmm, I want more!
