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

[Haibo Liu]

Dear Ivan,

Thanks for the prompt reply!
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
  
Yes, the TriG format does work!

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.

  
The TriX format failed with error message:

The processing instruction target matching "[xX][mM][lL]" is not 
allowed. [line 4, column 6]

The first few lines of the TriX file:
<?xml version='1.0' encoding='UTF-8'?>
<TriX xmlns='http://www.w3.org/2004/03/trix/trix-1/'>
</TriX>
<?xml version='1.0' encoding='UTF-8'?>
<TriX xmlns='http://www.w3.org/2004/03/trix/trix-1/'>
   <graph>


Thanks a lot,

Haibo
   
Cheers,
Ivan

Dear,

I have a question about reserving contexts in serialization. I'm running
a context based Sesame-SwiftOWLIM triple store. So the statements are
organized under various contexts. However when I load the serialized
N-Triples into a Sesame-SwiftOWLIM server through the openrdf-workbench,
the only context visible is the file name just loaded, all other
contexts  disappeared.

My questions are:
1. Does the  serialization reserve the context in the triple store?
2. How to make the serialization reserve the context and be able to be
loaded that way (organized under contexts)?

Thanks,

Haibo
