Hi All,

I am a GSOC student and I am working on Open Metadata Search. Please visit
the following link if you are required any information about the project.

http://wiki.eclipse.org/Open_Metadata_Search

My target is to register the EMF models for JavaEE which I can find in the
WTP in the EMF Index and call search operations.

I have already set up the wtp and looking forward to add the index plugins
into my plugin project. I have the problem of how to add these index
plugins into my plugin project.

Please be kind enough to help me in adding these index plugins.

Thanks in advance.

Regards,
Sajith.

Hi Sakith

note that currently EMF Index is quite preliminary and may change
drastically in the near future.

Here is how it currently works:

1) You enable indexing by adding the EMF Index nature to the projects
containing your models.
2) You configure the kind of information that should be extracted and
indexed by implementing a ResourceIndexer. You can inherit from the
ResourceIndexerImpl that already provides protected methods for the
interesting hooks. Your resource indexer has to be registered to the
org.eclipse.emf.index.indexer extension point.
3) You get a hold on the current index store by means of
org.eclipse.emf.index.ui.internal.EmfIndexUIPlugin.getDefaul t().getIndexStore()
4) Queries are created using the appropriate DAO, e.g.
indexStore.eObjectDAO().createQuery().name("objName")

The rest should be easy to figure out yourself.

Regards
Jan
