update on Grails Neo4j GORM plugin
The milestone release 1.0.0.M2 of the Neo4j Grails GORM plugin was published a couple of days ago. The plugin provides a GORM compliant implementation backed by a Neo4j datastore. This means you can switch any Grails application to use Neo4j by simply exchanging the GORM plugin used.
Plugin documentation can be found at http://springsource.github.com/grails-data-mapping/neo4j/manual/index.html. There is also a very minimal demo application available at http://neo4j-grails-demo.herokuapp.com/, see https://github.com/sarmbruster/neo4jsample for the source code. The demo app consists of three trivial domain classes with scaffolding controllers – nothing more for now.
Since there is currently the Neo4j Challange in progress, I’ve decided to participate there. As already stated the neo4jsample demo application is very minimal but it its intention is to serve as a starting point for your own Grails application using Neo4j as datastore backend. If you want support this project in the neo4j challenge, please send a tweet.
