>                 Key: NXP-3615
>                 URL: http://jira.nuxeo.org/browse/NXP-3615
>             Project: Nuxeo Enterprise Platform
>          Issue Type: Bug
>    Affects Versions: 5.2 GA

> Items to be covered:
>  - the entity manager opened by getTaggingProvider is never closed on 
> component close.
> Not a finalize() method. The TagServiceImpl is a Nuxeo Component, it has an 
> activate() and deactivate() method where initialization and shutdown can be 
> done.
> - getOrCreateTag: this uses getChildren with a filter, but a filter is quite 
> costly in general as the filtering is done in Nuxeo and not in db. It would 
> be better to make a core query like "SELECT * FROM Tag WHERE ecm:parentId = ? 
> AND tag:label = ?"
>  - tag.config: what is all this??? is the goal to read .properties and some 
> XML configuration files? Why not use the standard Nuxeo mechanism that reads 
> property files in nuxeo.ear/config, and extension points if you need to use 
> XML stuff? tagservice.cfg.xml doesn't have to follow Hibernate syntax, does 
> it? Using JAXB is way overkill. This should be either in an extension point, 
> or in simple documented nuxeo Framework properties.
> It's overkill in terms of reinventing a schema and parsing method that's 
> nonstandard for Nuxeo and adds a number of classes and files that could be 
> avoided. Nuxeo has standardized on extension point and properties, they must 
> be used.
> The extension point seems to be conflict with the request to be easy to 
> configure it from outside (not by rebuilding the code). I think the best 
> solution is to have a proper tagservice-db.properties file in nuxeo.ear/config
>  - have Nuseo book updated.
>  - fix the last unit test in TestTagService
