OData Accessing CustomMeta info empty

Question

We are trying to configure the access to the Broker via the Odata protocol. We already get keywords information with simple queries like:

Keywords.Take(100)

The problem is when we try to get CustomMetas, our result query is empty.

from x in CustomMetas
where x.PublicationId == 41
select x

I guess we have some misconfiguration problem in the cd_storage, but logs show a warning related to AmbientData.

• Is it necessary to configure Ambient Data for using CustomMeta info?
• Do we need a special typeMapping for this case, different from the Query one?

I post the logs for the query shown before.

We are using Tridion 2013 SP1 and have installed the WS in a RHEL as a java application.

Thank you

The problem was a missconfiguration in the cd_storage_conf.xml file contained in the web service. The taxonomy information is stored in the db by the deployer, and I had in the WS that the Query type would be consulted from the default source, which was the filesystem. The ODATA service is using the query type for getting the information, so there was the problem. My query was trying to retrieve information from the filesystem, when it's stored in the DB. Then, I configured the Query access to db instead of the FS and I republished the category. Now it's working perfectly.

It would be wonderful to have a section in the OData configuration telling how the cd_storage_conf.xml has to be configured for using properly this service.
