Creating Solr core on a selected set of LMF contexts (graphs)

[Rohana Rajapakse]

Hi,

Can someone tell me how to create a Solr core on data from one or more selected LMF contexts (graphs)?

Thanks

Rohana

Hi Rohana,

First, take into account that LDPath, the language used to configure the
Semantic Search engine in LMF, is now being developed in Apache Marmotta
[1]; so CCing users@marmotta for replying your question also there.

For limiting the LDPath evaluation to a subset of context/s (graph/s),
you'd need to use the expression:

@graph context ;

You can find some examples included in the LDPath test suite [2]. I
think the documentation needs to be updated.

Please, take into account that such feature [3] has been included in the
latest release of LDPath (3.1.0-incubating), therefore only available in
current develop branch of LMF, which should be released in few weeks.

Cheers,
