Re: [xml-dev] XML to graph

[Ihe Onwuka <ihe.onwuka@gmail.com>]

You will note that the data doesn't have a unique id. Title certainly isn't unique, if you consider how many movies there have been called Batman or Treasure Island.

Now I may encounter data about this movie from another source that covers different facets , for example it's box office takings or movie reviews. 

So it's a classic semantic web application. I want to amalgamate disparate data about the same fact in one entity. As I said I have a transformation that does this but it doesn't scale very well because I have to search the entire movie base to find the best match. To overcome this I have to adopt a mapReduce-ish approach to solve the problem.

The thinking is a graphical representation would eliminate that problem because a graph gives me a persistent data structure  already  indexed for retrieval via several different axes, whereas indexes constructed in the XSLT transformation for the same purpose  are ephemeral and would need to be reconstructed every time you ran the transformation.

Should be pretty straight forward to import that into Neo4J or Titan.  Neo might be simplest, in particular via conversion of the data into JSON.  However, Titan might give you other capabilities such as using Hadoop type processing either for import or for subsequent analytics. Without knowing more about the business requirements can't really give you much more than that...

I would like  to convert the XML snippet below to a multi-relational graph representation. 

One way is to transform a triple store via RDF. Another which I am less familiar with is to transform to graphML followed by a subsequent import into some graph database tool.

The graphical representation is desirable for processing rather than visualization reasons. Chiefly I have a matching algorthim implemented in XSLT which works fine but doesn't scale well, a problem that I think can be solved with a graphical representation. 

I am keen to hear from my elders and betters on the subject.
