It is also worth noting that ProcessUtils is only used to provide the
dataset locking functionality which helps prevents databases being used
from multiple JVMs at a time which may be a non-issue on Android since how
likely is is that more than one app will try and use the same TDB database?

The JSON-LD support through JSON-LD-Java also uses HTTPClient (to load
@contexts), but it can be statically overridden, if needed:

Hi Sören,
Thanks for that assessment.
Re: Xerces
Jena uses Xerces for datatypes - java.xml stiff provides Java types to
handle xml values but jena uses Xerces internals for literal parsing and
for the knowledge contained in the derived types hierarchy. It's not an
insignificant amount of wor
You can configure the footprint of TDB in 32 bit "direct" mode for
smaller datasets:

You would probably need https://github.com/SQLDroid/SQLDroid so you
get a JDBC driver.

Might it make sense to use a different persistence engine on Android since
it probably will not have the huge datasets that TDB is designed for. It
might make sense to have a small store available for small devices. Just a
thought.

Hi Andy,
thanks for your feedback and sorry for taking so long to reply. It would
be great to get Android support into mainline Jena and I'm willing to
help. It might be necessary to build an extra jar package for Android
though, similar to what jena-osgi does.
Is there are anything the Jena
Thank you very much for all these hints!
Yes it is SOLR and the hint on the text/search integration was helpful!!!

SPARQL results are HTTP-streamed back from Fuseki (and in TDB
programmatically), as long as you don't use ORDER and select a
streamable serialization format like JSON (not JSON-LD)
That is exactly what I do in

Dear community
does anyone know how to query RDF Data with SPARQL in huge graphs using
Jena so, that a portion of rdf triples is processed - say 1000 triples
at a time ?
I need this in order to INDEX triples in a search engine, need therefore
to access every triple but not all at a time ...

Hi Sören,
Interesting approach - having something that will be able to track more
easily the evolution of the Jena codebase is great to see. There seem
to have been an increase in questions on StackOverflow and on
answer.semanticweb about Jena on Android over the last few months so
great tim
Hi all,
We are working on some Android app prototypes that deal with RDF data.
To make things easier, we have created a version of Apache Jena that
runs on Android. It basically consists of a bunch of Maven build files
that do some repackaging of the original Jena jars in order to make them
