 |
|
Hi all,
I have been studying on MDA and I met MOF, a standardization of OMG for
metamodels. One of these metamodels is the UML metamodel. Looking at this
metamodel noticed that he has a lot of thing in common with ValueType
Framework, but in a way a little more abstract. Our idea is the creation of
a tool MDA Free. As metamodels repository nor a reflection schema that it
can obtain the complete model in runtime for Delphi still doesn't exist I
thought about beginning for UML-Metamodel and then, to create reflexive
interfaces to have access to this Metamodel.
The idea is that I can represent any model UML (only the part of classes
for the time being) and to create objects starting from metadada stored in
the repository. One of these metamodelos is the metamodelo UML. Looking at
this metamodelo noticed that he has a lot of thing in common with ValueType
Framework, but in a way a little more abstract.
This will later be able to be used by OPF or MVP.
Unhappily my knowledge are not very big and I can be confusing some things.
Will it be that anybody can be explained that can be really done?
Am I in the right road?

The Value Type Framework is indeed a metadata type of framework; AFAIK both
Bold and ECO use similar concepts. I have designed my own VTF and use it to
power both OPF and MVP frameworks; the only thing I haven't done yet is to
provide a RAD design environment, but I am not sure if the domain would work
as cleanly in a RAD environment.

I have yet to be convinced that a RAD environment is actually useful for
that :-)

I would agree, but I still wonder if Bold/ECO is doing it right and I should
join in :-)

Join in, join in!
ECO II is a fantastic architecture for OPF work - and it's much more
pluggable than any previous version, so it should be possible to extend it
in all sorts of directions. I can't wait to be able to afford licenses...

Sorry Bryan, but any system that requires multiple classes in one unit is
not ideal.
I want much more control over where the code is placed )

That's just Object Pascal for you though. It's either lots of classes in a
single file, or lots of interfaces in a single file, either way the words
"in a single file" echo.

Use C# then, it's a much nicer .net implementation.
