Search or read data for additional applications

If you use Solr as your database or index, use the Rest-API of Solr for searching or / and getting data in XML or JSON format or use Solr Client APIs to get data with your favorite programming language.

Or if you use a triple store as database use its standard SPARQL interface.

Libraries for different programming languages

Data enrichment and data analysis plugins
