Very nice story indeed. The platform is also very elegantly defined.

But I feel an important thing is missing – it is the time axis. Some facts are temporary by nature and don’t stay truth forever, same with relationships. To some degree one can manage this by keeping timestamps and time periods in corresponding properties associated with everything, but I feel it will be more natural if the time component is somehow managed by the Graph platform so it has an intrinsic notion of time. This will allow to keep “versions” of the graph and to analyze its evolution over time.

Comment on Exploring Wikipedia with Gremlin Graph Traversals by Marko A. Rodriguez

Hello,

Most natural graphs/networks have a similar degree distribution. In other words, natural graphs have mostly vertices with a low-degree and very few vertices with a high-degree. To figure out which vertex has the highest in (or out) degree, you can simply do:

vertex = null; degree = 0;
g.V.sideEffect{d = it.out.count(); if(d > degree) {vertex = it; degree = d}}

You can get fancy with that code motif to get the top 10, etc.

Thanks for reading,
Marko.

Very interesting to see the in- and out- degree distributions for Wikipedia. The most common in-degree is just one! What are those few articles that have in-degrees in the millions?

You can find the raw data dumps at the DBPedia project’s download page: http://wiki.dbpedia.org/Downloads37. Enjoy.

Fascinating article, as usual. Is there a way to get access to the DBPedia files to reproduce these experiments?

Comment on On the Nature of Pipes by Jogger: almost like named_scopes « Another Word For It

Jogger: almost like named_scopes « Another Word For It — Mon, 05 Mar 2012 00:15:54 +0000

[...] Remember the named_scopes from back in the days when you were using rails? Jogger gives you named traversals and is a little bit like named scopes. Jogger groups multiple pacer traversals together and give them a name. Pacer traversals are are like pipes. What are pipes? Pipes are great!! [...]

That was an awesome and very entertaining overview! I’m looking forward to playing in TinkerPop land. Thank you for instigating and creating.

Perhaps Gremlins cousin Gizmo is toiling in the TinkerPop with a new looking glass of relative awareness calibrated to the individual graphical perspective of each conceptual thing, capable of facilitating an instantaeous blue paint can click on the blueprints. Will the paint burst the pipes, spill out of the frames and splash onto gremlins head in echoing laughter?
