[gme-users] copy and paste references

[Aditya Agrawal]

To add fuel to this fire I would like to ask if there are any plans to
clean up the way libraries are managed in GME. 

The reason the problem mentioned below surfaces is because the library
is copied into the project. If the libraries are implemented such that
they are not copied in then the below mentioned problem will not be
there.

Thanks,
Adi

On the same topic, we have a small problem with the way models that are
built using the same single underlying imported library, are merged.

The scenario we have is different people have to work on building
different
aspects of the same modeling paradigm, but everyone is using the same
library, say ESML. Assuming the common portions of the extended library
are
captured, the individual developers are free to extend their aspects of
the
paradigm. Now when the aspects need to be merged, it would be nice if
the
copy/paste done as part of the merging, maintained the reference
information of elements of each aspect to elements defined in the
imported
library, instead of

1. Either invalidating the references because GME keeps track of objects
   via id which obviously fails when doing copy/paste. 
2. Having multiple copies of the same base imported library.

I was wondering if it is possible to provide such support for atleast
MetaGME paradigm in GME, as the combination of kind and type should be
unique in MetaGME.

We (Adi and me) discussed a bit on trying to solve it on the same lines
of
the LibraryUpdate tool that he implemented. I am looking for arguments
for/against having such support in GME.

Without this, we effectively have to serialize the process of creating
meta-models, which IMHO, is a waste of time.

Comments/Suggestions very welcome.
