New issue 109 by csarasua...@gmail.com: Provenance of links
http://code.google.com/p/void-impl/issues/detail?id=109

Hi,

When doing research in the field of data interlinking, we often use linked
data sets from the LOD cloud. In my opinion, it would be very useful to
have some information on the provenance of links within voiD descriptions
of data sets (i.e. related to void:Linkset). For example:

* how were the links generated? automatically / semi-automatically /
manually
* in case the process was done (semi-)automatically, which was the
interlinking tool used? Silk, MeLinDa, LIMES, LogMap ...
* in case the process was done manually, who were the agents involved in
the definition of links?

I need manually generated or manually reviewed links for an evaluation, and
I could hardly find this information at the DataHub or in voiD files.

Kind regards,
Cristina

This is related to Issue #3 (provenance information). I'd say that existing
provenance vocabularies, including W3C's PROV-O, are quite suitable and
probably sufficient for expressing this kind of information.

The only thing not obviously covered there is the distinction between
manual/semi-automatic/fully-automatic processes. For this, a specialisation
of PROV-O focused specifically on expressing the provenance of RDF links
could be a good idea.

Whether publishers will include such information in their VoID files is of
course a separate question. A first step here would be to encourage the
developers of link generation tools to generate provenance information
along with the links, in a consistent format.
