Re: [Owlim-discussion] context in triples after serialization

[Ivan Peikov]

Hi Haibo,

In order to preserve the context across serialization/import procedure you 
need to utilize a context-aware RDF format, e.g. TriG. After you serialize 
your repository in some file e.g. export.trig you need to execute the 
following steps in the workbench:

1/ Go to [Add]
2/ Choose Data format: TriG
3/ Choose RDF Data File: export.trig
4/ Clear the Context textfield (it was set to the URI of the file). If you 
don't clear this field all RDF will go to the <file://export.trig> context or 
alike.
5/ Upload

This should import back your data in the respective contexts. You can also use 
the TriX format (another XML-based context-aware RDF serialization format).
Let me know if this worked for you.


Cheers,
Ivan
