[Neo] Create/Modify Graph
Hi, I'm new to neo4j. I successfully installed and went through the getting started example. I also installed neoclipse, which seems to be a nice tool to look at the graphdb. Nonetheless, I have a few questions. 1. How do I add nodes to an existing graph? So far, I created a simple graph which stored in var/base and visible from neoclipse, however when I modify my script to create additional nodes and relationship, changes are not visible in neoclipse, although I quit neoclise prior to adding nodes and edges. 2. How do I list overall relationship? I found graphDb.getAllNodes() but not graphDb.getAllRelationship(), nor graphDb.getNumberOfRelationship() to loop through. Of course I understand that the prefered solution would be to traverse the graph, but before going further in learning about neo4j, I just wanted to check that node and edge creations succeeded. 3. What happen if I create a node that already exists - for instance when I rerun my code? I get no error message on existing nodes, but new nodes are not created either or at list not visible in neoclipse. Thanks in advance for answers, Pierre ___ Neo mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

I am thinking about how to construct triple store based on verbosequadstore of neo4j. The problem that I am going to have too many contexts (I want to model version as context), and I think the verbose quad store attaching context to the reference node. Is it possible to manupulate the quad store to have subcontexts attached to the ref node and then attach actual contexts to subcontexts? The second issue, the context node may have 10mln or more nodes attached. Would it create perfomance problems? The other question if I use verboseQuadstore to populate the db can I return to neo API to traverse the nodes or I will stack with Sail? (I mean I want to use build -in sail facility to index and load the db, but to use my own logic to access nodes instead of spaql? Or I will be forced to reindex? (I need to lookup nod_id by uri to be able traverse from particular node?

[Neo] Gremlin 0.2 (Gremicide) Released
Hi,
While everyone is happy on the Neo4j 1.0 release, I'd like to point you
all to Gremlin 0.2 (Gremicide) which was released on Sunday. The release
notes are provided below:
http://wiki.github.com/tinkerpop/gremlin/release-notes
A cool rundown of things that might be of interest to this list:
1. JUNG algorithms directly supported
-- http://wiki.github.com/tinkerpop/gremlin/working-with-jung-algorithms
-- the list of provided algorithms will grow as time goes on
2. Direct SPARQL support for SAIL-based graphs
-- list sail:sparql(graph?, string)
3. Ability to define function and paths both natively in Gremlin or in Java
-- http://wiki.github.com/tinkerpop/gremlin/user-defined-functions
-- http://wiki.github.com/tinkerpop/gremlin/user-defined-paths
If you are interested in trying Gremlin over your new Neo4j 1.0 instance,
just:
gremlin $_g := neo4j:open('/tmp/mygraph')
Take care,
Marko.

Re: [Neo] Announcing Neo4j 1.0
Hi, Johan. Small question: The Kernel distribution includes jta-1_1.jar and the APOC distribution uses the Geronimo JTA jar. Is there any functional difference or any reason to not use the Geronimo version in all cases?
