How do I implement revisions with neo4j?

Question

I have an object and I need to keep a history of all changes made to it. How would I implement this using neo4j?

Answer 1

You could also approach it from the other side:

(pages)-[:VERSION]->(V1)-[:VERSION]->(V2)-[:VERSION]->(V3)
   ^                                                   ^
   |                                                   |
category                                            current
  node                                          version of page

advantage : when you create a new version, you just add it at the end of the chain, no need to "insert" it between the (page) and the current version.

disadvantage :you can't just throw away old versions, unless you reconstruct the chain. But this is probably not a frequent operation.
