Maintaining Your Own Gremlin Language Implementations
|

Hi,
There are people pushing updates to Gremlin-Scala in the Tinkubator. Stephen and I talked this morning and we think that it would be best if individuals kept their clones (or primary branches) in their respective individual repos. Next, I've added a section at the bottom of the following page:... more »

Design Consideration
|
| |
Greetings! I'm looking to apply some 'dynamic weighting' to graph traversals. For example: DIST-MAP dist : weight 1 : 10 2 : 8 3 : 6 4 : 4 5 : 2 NodeA -- related --> NodeB <-- related (distance 5) -- NodeC NodeB <-- related (distance 2) -- **NodeD* NodeB <-- related (distance 1) -- NodeE NodeA -- related --> NodeH <-- related (distance 2) -- **NodeD*... more »

Public constructors for OrientDB/Neo4j Vertex/Edge and Neo4j transaction checking.
|
| |
Hi,
I have made the constructors for OrientVertex/OrientEdge and Neo4jVertex/Neo4jEdge public as they were back in 1.x. This should make it easy for OrientDB's GREMLIN function and Neo4j's Gremlin plugin to go from their raw representation to Blueprints. Moreover, I believe this fixes the remote: issue OrientDB is having with Blueprints element serialization.... more »

Rexster 0.8 Old Syntax to Achieve Order step?
|

Another group at my company setup a Rexster server running 0.8 that I'm trying to query. I'd like to run a query like the following (grab the vertex of the highest degree who has name property of 'algebra'): g.idx('dbpedia')[[name:'algebr a']].order{it.outE.count()}.ne xt() But the order step is not recognized on version 0.8.... more »

ain't no thing but a chicken wing

I really love tinkerpop; but evertime I come back to my project that uses it it makes we want to cry... The new germlin always breaks my code; and I can never figure out how to build an old gremlin. If I use the "1.4" tag (which matches my code I'm trying to migrate to a new machine) and I do a 'mvn install' I get this:... more »

TinkerPop 2.1.0 -- an apology to our supporting vendors.
|
| |
Hi everyone,
TinkerPop 2 has some great changes in it, but in all those changes, there were some hasty moves that were made that led to a suboptimal release. To rectify this unfortunate situation, TinkerPop needs to work on a 2.1.0 release that will provide fixes to the following issues. Luckily, for most everyday users, these are non-issues. However, for our vendors, it is important we fix these sooner than later so they can get TinkerPop2 confidently into their products.... more »
