Spring Data Graph - Neo4j Support 1.0.0.M4 Released

[trisberg]

Dear Spring Community,

We are pleased to announce that a new milestone release (1.0.0.M4) of the Spring Data Graph 1.0 project with Neo4j support is now available!
The primary goal of the <b>Spring Data</B> project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.
The Graph Neo4j module provides integration with the Neo4j (http://neo4j.org) graph database.

Downloads (http://www.springsource.com/download/community?project=Spring%20Data&version=1.0.0.M4) | JavaDocs (http://static.springsource.org/spring-data/data-graph/docs/1.0.0.M4/api/) | Reference Documentation (http://static.springsource.org/spring-data/data-graph/docs/1.0.0.M4/reference/html/) | Changelog (http://static.springframework.org/spring-data/data-graph/docs/1.0.0.M4/changelog.txt)

To learn more about the project, visit the Spring Data Homepage (http://www.springsource.org/spring-data).

The features in Spring Data Graph 1.0.0 M4 include:


update to Neo4j-1.3.M04
simplification of detached/attached state
all node entities are detached at creation, must call persist()
attach() renamed to persist()
separate indices per domain class
support for fulltext indices
fixed direct lookup of numerically indexed values
relationships via relateTo are now also restricted to one per type,direction and target
added EntityPath/EntityPathMapper for entity based Neo4jTemplate callbacks
added EntityEvaluator for entity based path evaluation
error handling for node type strategy called on non type nodes
FieldTraversalDescriptionBuilder build method parametrization
re-enabled, updated and fixed cross-store persistence
graph managed fields no longer have to be annotated with @Transient (the aspect takes care of that)
changed documentation format to guidebook, added tutorial as first part


Looking forward to your feedback on the forum (http://forum.springsource.org/forumdisplay.php?f=80) or in the issue tracker (https://jira.springsource.org/browse/DATAGRAPH).

I also updated the examples for Spring Data Graph to the current M4 build.

You can find them here: http://github.com/springSource/spring-data-graph-examples.

In doing that I also rewrote some parts of the IMDB app (https://github.com/SpringSource/spring-data-graph-examples/tree/master/imdb), so that the in-graph index now also used Spring Data Graph, that cut down the necessary code (https://github.com/SpringSource/spring-data-graph-examples/blob/master/imdb/src/main/java/org/neo4j/examples/imdb/domain/ImdbSearchEngineImpl.java) to almost the half size (180 lines to about 100).

Cheers

Michael
