Is there any tool to query MongoDB using SPARQL ?
I store object using an RDF schema (boo Mongo no schema ^^), and now i looking for a tool/server to query the datastore using SPARQL.
I started to write a SPARQL parser, but if such as tool exists, i think i would use it.
Thanks in advance.
I would suggest, if you use RDF, that you have a look at Neo4J database, rather than MongoDB. Neo4J is a graph database and is well suited for manipulation of RDF data.
Querying any datastore with SPARQL is rather more complex than just writing a parser - you also need a query engine to process the query and some method to get your data into a form the engine understands OR hook your data into the API of the engine you re using.
I ve got both MongoDB and Neo4j down on my lists of Triple Stores to support in my RDF API eventually but this support is months off. I don t know of any existing SPARQL engines which can query MongoDB
Are there any Java libraries available that allow RDF processing on the Google App Engine?
