We decided that we needed a meta-data character that wasn't :. Instead,
you now write: r~TYPE

Hi there,
Haven't tried it, but I would guess that you have to use the same version of
things. Use 1.4.M05 of neo4j-shell, or 1.4-SNAPSHOT of neo4j, and you should
be good to go.

If the property op_type contains a Number, you can't compare it against a
string. Could that be the problem?

Yes, op_type is a number property.
I'm wondering how to specify this in the query.

Hello graphistas,
Today we’re releasing the fifth and final milestone in our 1.4 “Kiruna Stol”
family. We’ve expanded our feature set to include Auto Indexing and paged
traversers for the REST API, the Cypher query language has seen some major
improvements and as always, we’ve squeezed more

Thanks for your answers. The correct quotation marks are working. Couldn't

It's under the return statement. I'll make it clearer. Thanks for the
pointer.
It is not possible now.
As part of the next milestone, which should come out tomorrow, we'll package
a Cypher-plugin, that allows you to do Gremlin queries over the wire:
http://docs.neo4j.org/chunked/1.4-SNAPSHOT/gremlin-plugin.html
If you are using a snapshot version, it should already be there.

Are you referring to what the implementation looks like? This is the source.
I haven't grokked it yet, so I can't give you a TL;DR;, sorry.

Hi there,
Your images are difficult to read on gmail. A gif might help. :)
I'm not quite certain on what is not working. In Cypher, your question would
look something like this:
START rules=(0)
MATCH (subReference
)-[:APPLIES]-(rules)-[:RULE]-(rule)-[r,:LESS_THAN]-(answer)
WHERE r.Threshhold 0
If it's any consolation, I've bumped the version of Scala to 2.9.0 already,
so the next milestone should work with GraphStream.
Regards,
Andrés

Good catch. Fixed in trunk now.

Hi there,
You are using an old version of graph-matching.
You should not have to depend on graph-matching. Just depend on cypher, and
it will pull the correct version of graph-matching.
If you want to depend on graph-matching explicitly, make sure you depend on
either 1.4.M04, or 1.4-SNAPSHOT.
