[Neo] encoding formats for tuples?

2009-08-03 Thread Rich Morin
I'm getting ready to write some scripts to glean relationship information from some disparate sources (eg, RubyGems metadata and output from MetricFu and YARD processing runs). I hope to pour all of this information into Neo4j as input for an online documentation system. Anyway, I'm trying to

Yeah, I think that a mentioning of graph databases should definately be in there somewhere! 2009/8/3 Rich Morin r...@cfcl.com: Looking at http://en.wikipedia.org/wiki/Database, I see nothing about graph databases.  Nor do I see a page on either this topic in general or Neo4j in particular.

Hi Mattias, With this information I was able to fix my dilemma.Thanks. One more thing. OK I already set-up the schema. Along with it is the expected values, range, data type, etc. But the thing is I cannot access or put values on the properties that I have created. I ran out of options, can u

Oh ok, you use the same methods for getting the classes and properties as for creating them: (the true/false 2:nd argument is the allowCreate option, so that if true then the class/property will be created if it didn't already exist). MetaStructureClass myClass = namespace.getMetaClass(

Oh I see, Maybe I have to refresh again. Anyway, just another question. For example I already have configured the meta structure, with all the data type( string, integer...), data range, etc. Can you give an idea on how can I use or put values in it? I'm lost here. Thanks. Jers On Mon, Aug 3,

Re: [Neo] meta structure

2009-08-03 Thread Mattias Persson
Well, the meta structure is really just a helper for keeping data according to a certain structure... if you make those checks against it yourself, that is. There's nothing automatic in validation or insertion by using this framework as of yet. Inserting data is still done by using the neo4j

Hi! If the link or two lead to very specific notes on setting up Neo4j for the language, that's fine. This depends on the project providing a Neo4j wrapper for the language. For instance the Ruby wrapper comes with a few example apps and documentation as well. On the other hand I don't think

[Neo] ReturnableEvaluator behaviour

2009-08-03 Thread Jonny Wray
Hi, I had a clarification question regarding the ReturnableEvaluator behaviour. When the evaluator returns false does that result in a stop of traversal also or does the traversal continue beyond the node not returned? I can see both being valid situations (I need the former) so just want to be

Re: [Neo] ReturnableEvaluator behaviour

2009-08-03 Thread Peter Neubauer
Jonny, the ReturnableEvaluator is just deciding whether the current node should be included in the set of results that are returned or not. It does not stop the traversal - that is the job of the StopEvaluator that returns a boolean for stopping the traversal. HTH /peter GTalk:
