Hi everyone,

Can Skosmos be used with other Triplestore/SPARQL server apart from
Apache Jena Fuseki? Since it relies on SPARQL queries I think that there
should be no problems but has anyone used it with any other SPARQL
server such as GraphDB, Virtuoso, AllegroGraph, etc.? If so, are there
any performances issues (I do not know if Skosmos uses some specific
optimizations provided by Apache Jena Fuseki which are not present in
the other triplestores)?

Thank you

Andrea

Hi Andrea

Many years ago we plugged Skosmos on Virtuoso. It required some tuning on the SPARQL queries, I think now they have been integrated in the main branch.

e.g. this deployment talks to a Virtuoso endpoint : https://data.legilux.public.lu/vocabulaires/fr/

Hi Thomas,

thank you for the reply. By "It required some tuning on the SPARQL queries" you mean that you had to manually change the source code of Skosmos and in particular optimized, somehow, the SPARQL queries?

Thank you

Andrea

Yes (see https://github.com/tfrancart/Skosmos/commits/master/model/sparql/GenericSparql.php)

But these changes have since been integrated in the source code of Skosmos, so you don't have to do it again.
