neo4j 2.2 support

[FlxVctr]

Please add neo4j 2.2(.1) support, as neo4j has major performance improvements in 2.2.

At the moment it only gives an empty warning if I try to import (and yes, database is shut down.)

Cheers :)

I too see a blank error message when trying to import my Neo4j database on Windows 7, JRE 7, Neo4j 2.2.0.

In the interim, what's the best way to get a graph out of Neo4j 2.2 and into Gephi 0.8.2? I suppose I could write my own little wrapper, or do a CSV export of some sort.

[FlxVctr]

Best way is to export graphml with shell tools: https://github.com/jexp/neo4j-shell-tools though it doesn't get the labels right and you will have to correct the graphml file to do so.

@FlxVctr Thank you. For the moment I've got it working with spreadsheet formats for the node and edge lists, since the queries to build them are straightforward and I don't need to round-trip the data back to neo4j yet. I'll have to check out the shell tools, too.

It will be more difficult than expected to adapt Neo4j to Gephi 0.9, since the new core no longer has the old delegates system.

Probably the new Neo4j plugin will be a simple importer and exporter of Neo4j files.

[FlxVctr]

That would be sad as dynamic loading would be handy to explore very large graphs ... if I get you right. What do you mean exactly by Neo4j-files?

[eduramiba]

I mean the database files. I still need to study what options we have. Also I'm not a neo4j expert at all...
