Thanks for the links and the info. 

I was talking about the EDG 7.2 feature "Commit Ontology to Git 
Repository". We found this feature extremely useful, and it saved us lots 
of tedious work of exporting, copying and renaming TTL files. With this 
feature, the "External Graph URI" of included sub-graph is not 
automatically persisted in the including sub-graph, however. 

Back to the origin of my question: I need to find a way to resolve 
<urn:x-evn-master:b> to a local file b.ttl, which was exported to the same 
directory as a.ttl in the git repository. I need to run the SHACL validator 
(https://github.com/TopQuadrant/shacl), which can not understand 
"*<urn:x-evn-master:a> 
owl:imports <urn:x-evn-master:b>*", but does understand  "*<urn:x-evn-master:a> 
owl:imports <file:b.ttl>*"  . This is why I was thinking of populating an 
additional triple to import <file:b.ttl>. This might just be a workaround 
though.

It would be much appreciated if you could provide some suggestion about how 
to resolve <urn:x-evn-master:b> to a local file b.ttl, such that the 
external SHACL validator can run through without changing the persisted TTL 
files by the EDG git feature. 

Thanks.

Regards, Kai
