So,
using this approach, you could potentially switch forth and back
between an Index-based step traversal betwen nodes, and a
reference-based traversal between nodes, maybe with some treshold
tweaking on when to switch involved?
And using the event model, you could even indicate that nodes

Hi,
I've been using neo4j for some time now and evaluated various GUI solutions.
(cytoscape, graphviz / xdot, gephi, plantUML)
My conclusion is that the neo4j eclipse gui is often the best solution for
complex structured graphs.
However, I have a few suggestions for improvement. (In order of
Hi!
Thanks for your input.
I'm working on a new version of neoclipse and hope to commit my changes
soon. Just waiting for my code base to get reasonably consistent :-)
The biggest change is that neoclipse will handle threads in a correct
manner, that is, there will only be exactly one
Hi there,
also, I would think an export/import db to/from GraphML button would
be nice and handy.

Hi to all,
I am a GSoC (Google Summer of Code) student working on adding support
for Neo4j in Gephi. I appreciate you to look at Gephi as a very nice
visualization tool. This week I will also finish the article
summarizing what have I done and what is needed to do. In fact Gephi
has much more
Martin,

Also, hav you tried to open big graphs with Gephi? I recently tried to
open the Neo4j db generated by the test of
http://github.com/neo4j/neo4j-spatial (run mvn clean test), but
things slowed down to a trickle. Not sure if what the limit is for
Gephi, and how to open/surf nodes with a depth-1
Peter,
about editing support = this is true. I firstly focused on core
abilities like importing and exporting including filtering abilities.
The fact is that another student is working on Data Laboratory, so the
place where it will be possible to change data. We are also thinking
about setting
Sorting by relevance is possible via
http://components.neo4j.org/neo4j-index/apidocs/org/neo4j/index/lucene/LuceneIndexService.html#getNodes(java.lang.String,%20java.lang.Object,%20org.apache.lucene.search.Sort).
Exposing this sorting thingie would require you to add that in the rest code
as well
Sticking with the original thread topic of requirements for neoclipse.
I find that if I accidentally open a view of a graph with more than
about 500 nodes to layout then the whole lot takes a very long time to
come back. Is there a way to either speed it up, or let the user
interrupt the process
I was changing the neo4j-rest server to use the new lucene-index framework
myself, and have been very frustrated with this problem. There seems to be
a lucene version conflict:
- org.neo4j.index.impl.lucene.LuceneIndex.search() uses
org.apache.lucene.Hits, which was removed in lucene 3.0
-
I copied that org.apache.lucene.Hits class into the lucene-index component,
so it exists there in that package (and has existed there since the birth of
this component). That's the class that LuceneIndex.search uses, not the one
from lucene-core-3 (since it has been removed).

so i have this jython code to import a shapefile using the ShapefileImporter

Your code has at least two (these are the obvious ones) issues:
1. You are trying to write Java in Python. This is Java:
ShapefileImporter importer = new ShapefileImporter(graphdb);
In Python you don't declare types, and you don't use 'new' to create new
instances.
2. You are mixing the python
My two-pence regarding neoclipse -
I am working on a set of data with about one million links between
nodes. It takes quite a long time to display that in neoclipse - so I
cut down the data set to about 5000 links between 500 or so nodes, and
there are about 6/7 connected components (like
