Hi Alfredas,
One thing I forgot to mention. You can express pattern match queries in Gremlin:
https://github.com/tinkerpop/gremlin/wiki/SPARQL-vs.-Gremlin
While not having the same syntax, you can still do pattern matching as a
traversal. But yes, I ultimately want to get an extension
Hi all!
Recently I started exploring things about graph databases in conjunction
with knowledge management and have run across the Neo4j. It now seems to me
that Neo4j can somehow be used with the semantic-mediawiki to store RDF and
quiery Neo4j with SPARQL.
Did anyone have any experience with
There is a rdf-sparql component to Neo4j that could in theory be
configured to be used as a backend for semantic mediawiki.
But you still have better chances to configure smw to use a
triplestore http://en.wikipedia.org/wiki/Triplestore
For more info see:
This looks great.
I've encountered a problem when following the example. Here I'm trying
to create a sail out of Neo4jGraph.
java.lang.RuntimeException: No such index exists: edges

Hi,
I apologize. When I said 1-to-1, I spoke with exaggeration. You will need to
create a GraphSail from a blank Neo4jGraph initially.
Sail sail = new GraphSail(new Neo4jGraph(/tmp/neo4jgraphsail))
At that point, you can move back and forth. The reason being, GraphSail
requires
Got it. It would be great to be able to use Sparql on neo4j or any
other Blueprint db.
Do you think it would be possible to map/translate sparql query to
gremlin/pipes?

Yea it would.

I plan to create a new DSL over Gremlin/Pipes that has a syntax flavor like
this. E.g.
x = []; y =
Well I'm in general interested in having all these different
mechanisms (native (traverse), pipes, gremlin, sparql) to query the
same graph.
That would give so much more flexibility when writing domain methods.
Ideally you would not want to write domain methods at all, but
annotate interfaces with
