t_xref & t_xrefsystem

[lubos]

Hello,

can anybody provide some information about these tables?
Especially  about their columns XrefID,client,supplier for t_xref
and XrefID,Supplier,link for t_xrefsystem.
I expect that XrefID is a primary key.
client and link referes to elements (t_object,t_diagram,...)
but I can't find out what the supplier refers to.

----
We want to join many projects into one, and since these project were created from the same basic project, we have a lot of elements with the same ea_guid that we don't want to collide.
We decided to rename ea_guid in all projects to assure that they will be unique in each project. but we have to rename all occurences consistently.
Exporting the whole project and importing with strip guid is not possible, since the XML file is very big (100MB and more) and EA crashed in import always.

thak you for any hints

I think the client/supplier works just like a regular relationship.
A relation alway's goes from client to supplier.
Depending what the t_xref is actually representing I guess that could be anything from an object to a stereotype.

I have expected it too, but I find the refered objects (with given ea_guid).
but since in each project there are only a few rows (30 max) in these tables, they are not so important and it is safe to ignore them in our migration proces...

thanks

err:: I CAN'T find the refered object ;-)
