HI all, I'm still using Compass 2.x (Hibernate GPS integration) but have been keen to migrate to Elasticsearch for quite a few months now, so I thought I'd ask what the current recommendation is? 1. Wait a bit longer (e.g. months) for a future release of Elasticsearch to include Compass-style OSEM, at least something to help migration. 2. Get involved with some of the projects that are covering similar ground, e.g. felipera's Play Framework stuff ([http://geeks.aretotally.in/play-framework-module-elastic-search-distributed-searching-with-json-http-rest-or-java](http://geeks.aretotally.in/play-framework-module-elastic-search-distributed-searching-with-json-http-rest-or-java)) 3. Start again from scratch, and manually call Elasticsearch for each entity change (not fun!). 4. Stay with Compass - it's fine (I'm not expecting this to be the answer). Any suggestions much appreciated! ---

Mu suggestion is to get involved with projects that will develop OSEM like capabilities and on top of that, Hibernate (or other ORM) integration. My hope is that the Java/JVM community will kick in and start developing different integrations on top of elasticsearch as has been done in other languages. Note, my plan was to possibly build something similar to OSEM and the ORM integration in elasticsearch, but currently, the preference is to focus on code elasticsearch features that will benefit a broader set of users, and let the community work on addons.

Alois starts a really good job about OSEM / ES : [https://github.com/aloiscochard/elasticsearch-osem](https://github.com/aloiscochard/elasticsearch-osem) > **[aloiscochard/elasticsearch-osem](https://github.com/aloiscochard/elasticsearch-osem)** > > elasticsearch-osem - ElasticSearch OSEM You can have a look at this and see if you can use it. There are some tests cases that really help to understand how it works. Hope this helps, David.

Thanks, Shay and David, I'll have a look at Alois's project and try to get something up and running. If I get the Hibernate integration layer working I'll contribute it to the community. Andrew ---

Just a quick update to mention my new OSEM/Hibernate integration project: > **[poblish/elasticsearch-osem](https://github.com/poblish/elasticsearch-osem)** > > elasticsearch-osem - ElasticSearch OSEM with Hibernate-ORM integration Essentially what I've done is extract the gps/device/Hibernate code from the final version of Compass, breaking the dependencies on the high-level Compass interfaces, and commenting-out the mapping, resource, and transaction calls until I had something that would build standalone (well, build against Hibernate 3.6 and Lucene 3.3). A bit of a hack, perhaps, but I figured that the Compass Hib code is tried and tested, and worth saving where possible. I merged the results into my fork of Alois's elasticsearch-osem project, leaving me the challenge of replacing the commented-out mapping, resource, transaction, etc. stuff with the ElasticSearch/OSEM replacements. While I'm doing this I'll also be refactoring to remove stuff that's obsolete, and trying to ensure that the Hibernate and GPS code fits in properly with the ES model. Very early days, so help and advice (and integration tests) much appreciated! ---
