SIOC

Hello,
I was wanting to produce RDF files for each member of a large online community of writers. It is using Drupal 7, so it has RDFa and many vocabularies "out of the box." I might want to add doac (description of a career), vcard RDF vocab, and perhaps bio.
I don't know if it is possible to go in now and create a file structure for holding data files that relate to each person. For example, starting with FOAF, I'd want to have a folders structure such as:
[username]/foaf.rdf
or better yet:
[user's real name/foaf.rdf

I'd like to share some quick thoughts on how Drupal Data could be described in RDF. The attached schema represents the mappings between the current Drupal data structure and the proposed RDF Schema, reusing existing ontologies such as Dublin Core, FOAF, SIOC and SKOS.

The green circles represent the Drupal objects (node, revision, user, role, term), with their equivalent RDF class. The rectangles are the values used in Drupal. It's important to differentiate a class from its actual instances (resources) which are each defined by a unique URI, see the examples below. This schema is meant to be simple, incomplete, and to show the main core features.
Comment and Node are 2 different elements in Drupal, they can be combined in the same Class with the recursive property sioc:has_reply (Comment as Node). Node and Revision objects are separate here as they are in the Drupal Data structure, but they could fundamentally be merged as well.

I presented SIOC at DrupalCon Barcelona, and showed how it can be used to describe online communities. The SIOC sioc:Item class which I used here as equivalent of a Node is a broad Class with many sub-types: AddressBook, AnnotationSet, AudioChannel, BookmarkFolder, MailingList, MessageBoard, BlogPost, BoardPost, WikiArticle... See the SIOC Types Module for more details.

I am very interested in the state of Social Networking direction for Drupal.
I would also be interested in writing/contributing modules if I knew how they would all fit together.

I propose a Bird-of-a-Feather (BOF) meeting on Social Networking in Drupal at DrupalCon2008 in Boston.

We can get to know all of the people working on Social Networking stuff for Drupal and create a coordinated
plan for making Drupal a top-notch Social Networking platform. (If this plan already exists, please fill me in on it.)

What do you think?
