Re: [topbraid-users] SQL TO RDF

Tue, 16 Sep 2014 07:35:43 -0700

Maarary; To be clear, TopBraid Live is not needed for this conversion.  You can use TopBraid Composer-ME.

The D2RQ wizard is a good choice, and one the DataView mapping is opened you can yse EXport > Export/Merge/Convert RDF Graphs to copy the data into an RDF file.

For a  SPARQLMotion solution, the sml:IterateOverSQL module will iterate through the result set of a SQL query, which can then be converted to RDF with an ApplyConstruct (basically a SPARQL CONSTRUCT query), etc., module.

Documentation on this can be found in TopBraid Composer Help > Reference > SPARQLMotion Library Reference.  There is also a useful section on our home page:

Hi Maarary. I missed your specific SQL reference. There is ‘import relational data using D2RQ’ wizard in TBC that is relevant.  When possible - please also review here:


Thanks,
Mark

Hi Maarary,

You can create an SDB connection file to your DB in TBC and create a SPARQLMotion script. You can find much detailed information in the TBC help file and at this page that should help you to get started http://www.topquadrant.com/knowledge-assets/product-documentation/

Thanks,
Mark

HI,

as part of a project that i'm running for an organization i have the requirement to convert some SQL data and RDF. These RDF data shall be store in a semantic database from which they will exposed as linked data. 


The semantic database is fixed and i have to use it. 



Hence i need an approach to routinely convert the SQL data in RDF and update my database with it. 


Is there a way that TopBraid can help me with these kind of task ? 


I red somewhere that SPAQRLMOTION could help with it.  However i can't get a hold on the right documentation. MoreOver it sounds like more TBC Mastro we will have to get TOPBRAIDLive, to run sparqlMotion Script. 


In short, what support TopBraid Provide for converting SQL to RDF. Is it a one time thing, or there might be a way to do it routinely ?
