Support for Importing and Exporting DCAT Metadata

[posixeleni]

To support importing data from data.gov and exporting in the same format for data.gov to ingest our metadata.

Need to research this:

Here is the metadata schema used in the US Government, which is based on DCAT: https://project-open-data.cio.gov/v1.1/schema/

As you can see, there are a lot of optional fields, but only a few required ones (title, description, keywords, contact, URL). We recently moved to the 1.1. of the schema.

Also note that Data.gov ingest local, state, and university data

http://catalog.data.gov/dataset?organization_type=Federal+Government

http://catalog.data.gov/dataset?organization_type=University

Regardless of what we do, we should make sure Data.gov harvests/ingests us.

And here is how Data.gov does the harvesting:

Here is a tool we can look at when working on support for DCAT/RDF http://rdforms.com/editors/dcat/

I just added the "harvesting" label to this issue but http://www.data.gov/developers/harvesting doesn't mention OAI-PHM (which is now supported as of Dataverse 4.5) so maybe this is a different type of harvesting.
