Sounds cool though I have to admit it will take me a bit to wrap my brain around picturing the implementation. I do get the idea of using XML to persits metadata though as we do that in VFE apps when we want to check metadata for a view into source control ( using Vault )

What your talking about in this Java framework seems to be a factory pattern for class instantiation, which is a familiar concept as well.

>>I definitely don't want to get in the middle of a pie throwing contest between you and Walter <g> ( I have the good sense never to try to punch above my weight class ) but I am interested in the idea of meta-data. I am a .net novice but love SQL as a data store and use it exclusively in my VFP apps. (thanks to the Feltmans - pretty sure I'd find it tedious without the strength of the framework) Having DBCX available on the VFP side is very powerful.

>>Anyway, I am very used to having a metadata store and data-driving a lot of stuff in VFP and have been looking for places in .Net where that would be appropriate. i realize classes are instantiated differently so some of factory patterns that are used in VFE might not be relevant. I use Strataframe in .NET and there is an ongoing discussion there, often fueled by Fox people, about encouraging Microfour to expand their Data Deployment Toolkit ( which uses smo to deploy and synch sql schemas ) to be more of a general metadata store. They already implement something like msgsvc as part of the framework.

>>>Walter, last year you kept criticizing my statement about how stored procs can be flexibile - NULL handling was part of your argument. Well, I demonstrated to everyone how you can use sprocs for updates that handle NULLs as well as "change-tracking". I know that a few people wound up using what I posted.

From what I've seen in the .NET world (but also the java world) and also from the .NET experts here, there really is a lack of realism what the power of data is and how data should be done.

>>>Some of your notions, specifically embedded meta-data in EXEs, are more hacked-out solutions, and hardly scalable (not only in the obvious sense, but also for the size of the development teamm). I really get the feeling from many of your posts that you often work on very small teams, or teams of one.
