Hi Andreas,I've seen the code in the source repository, however I'm not sure (at least yet) that its going to be helpful for my use case. What I am looking to do is that I have a set of nodes that occur with certain ordering and contain relationships based on some transportation metadata (trainpath/walkingpath etc). I would like to do some pattern matching by selecting these nodes with their orderings (i.e. a potential subgraph) out of my data set which can be millions of nodes. Is there a way to do this without using loops or using the Traverser API. I was wondering if sparql and RDF could help with this. See example below:
DataSet: Million nodes with a property called nodetype of "trainstop","foodstop","pointofinterest","attraction"Query: Find all paths with a nodetype of trainstop occuring before a nodetype of "pointofinterest" occuring before a nodetype of "attraction"Data Returned: A set of paths Some insight into this would be much appreciated.Best Regards > From: [email protected] > Date: Mon, 14 Feb 2011 15:28:57 +0100 > To: [email protected] > Subject: Re: [Neo4j] Graph pattern matching component > > Hey Saikat, > > The component site has some example code: > http://components.neo4j.org/neo4j-graph-matching/ > > Is there something specific you have in mind? > > -Andreas > > On Feb 11, 2011, at 6:48 PM, Saikat Kanjilal wrote: > > > > > Hi Everyone,I am reading up on email threads and documentation pertaining > > to the pattern matching component and am considering using it to advance > > the next set of features for the code.
