Hi Simone, Thanks for the clarifications. I haven't had much need for graph algorithms other than traversal and shortest path myself, but perhaps I haven't been thinking hard enough about my data :-).
Based on your clarification, I realize that while there is probably going to be /some/ overlap, they are addressing different areas, and I think commons-graph would be a good initiative, and for my purposes, would probably help me address different problems against a graph backed by neo4j. Regarding contributing, I would probably be focusing on /using/ the commons-graph algos against neo4j, so I would probably be able to write up user level tests/documentation if appropriate. So fwiw, +1. -sujit On Wed, 2011-06-08 at 08:18 +0200, Simone Tripodi wrote: > Hi Sujit, > thanks for your contribution, but just to avoid misunderstandings: > Neo4J is a great graph database, OTOH commons-graph aims to create a > higher-level APIs to interact with graphs and providing general > purpose algorithms implementation for a large set of known problems, > not just traversal/shortest path.
