Re: Neo4j Graph Database 1.0 released
#2Neo4J is a great tool - I have used it with the Ruby wrappers.
A little off topic but: I think that the AGPL (which is used for Neo4J) is a good license but I wish that dual licensed projects would be a bit more up front on what the cost of the commercial waiver is for various use scenarios. For me the issue is that I would like to know up front how much 'commercial' use would cost if I would happen to have a customer who could not live with AGPL license terms.

My bad: Neo4J did have their prices listed.

Could you post the link?
Also curious if they list "powered by" - who uses Neo in real world applications...?

Can you use neo4j to store weighted graphs? Looking at their api it doesn't seem like there's any way to specify edge weights (or any other metadata about edges).

You can set properties (including weights, though not sure if you can define said weights in a tightly integrated manner - they're just an additional property) on nodes and edges ("relationships"). It's right there in the getting started guide's "Create a small graph" section:
http://wiki.neo4j.org/content/Getting_Started_Guide#Create_a...
Weights are treated like any other metadata.

#8I found this presentation from Emil (Jan 19, 2010) much more informative than the podcast linked to from the release:

Edit:
What's really intriguing is what they're going to roll out with v2.0 - instead of basic, customer-written sharding algos, they're going to supply automatic sharding based on graph clustering algos.

From the AGPL:
"Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License."
So, if you write a wrapper licensed as gplv3 (say, a set of Clojure bindings), distribute the source for that and for neo4j, and load the wrapper (a gplv3 licensed work) into your program, the network interaction cluse of the agpl should not trigger, no?
