RDFa

Importing catalogues

We need to import arbritary catalogues (spreadsheets) into RDFable Drupal nodes.

We suggest the following as a way forward: before implementing this, we want to see if this would be useful to the broader Drupal RDF community, and whether it is compatible with other existing proposals:

Option 1: Dynamically create content types

For each import format dynamically create a node type that matches the field structure. Provide an RDF mapping for the created node type to enable the imported items to be tagged up with RDF.

Option 2: Define a generic content type for imports

Spreadsheets are imported into two node types. The 'header' includes the spreadsheet file and information about it's structure. A second content type is used to import each row. A row is a list of attributes taken from the column data for that row.

We also need to consider round-tripping issues, as follows:

For those of you who have been following Drupal 7 core development, you might be aware that many RDF patches have already been committed. So, before it's old news: Drupal 7 will ship with RDFa enabled by default on nodes, comments, terms and users!

The first alpha release of Drupal 7 will be created next Friday Jan 15th. We've already incorporated most of the feedback we received from the semweb community so far, but I wanted to give the community a last chance to review the RDFa markup and the default RDF mappings we use before it's too late. I should emphasize that all the markup and default RDF mappings that we ship in core will be pretty much set in stone after the stable release of Drupal 7, hence this call for feedback. Site administrators who care about semantics will be able to alter these mappings by installing extra modules, but many people (read several 10K sites) will just install Drupal 7 and not care about the semantics it generates. Therefore we want to make sure the RDFa generated by Drupal out of the box is somewhat correct and does not make folks from the semantic/pedantic web community angry :) - we've tried to keep the semantics as generic as possible for that reason.

RDF mappings

I've created a diagram representing the default semantics of the core data structure which has been committed and I would appreciate feedback on the RDF terms we've used.

I am interested in building RDFa features into a number of real estate sites I have worked on. I have a pre-release module that will bridge drupal and MLSpin.com IDX data using property node type. I have been looking for existing namespaces or ontologies, alongs the lines of foaf and dc that would categories real estate or listings. If there is not an existing namespace, then I am interested getting it started. Has anyone found, built or published on?

DrupalCon DC 2009 featured a nice selection of RDF related sessions. 2 regular presentations served as introduction to those who were unfamiliar with the topic, or just wanted to refresh their mind with the latest happenings.
