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?

My Drupal real estate site
I had a custom MLS module built for my site 3.5 years ago. I describe the site in detail below. The site is Drupal 4.7 and I'm looking to upgrade it to 6 and collaborate on the effort with other realtors. I had this site built so I could do more for my clients as well as use it as a tool for better search engine rankings. I have studied search engine optimization and hired a number of consultants to ensure I know it well. The site ranks #1 on Google for "Lake Tahoe Real Estate".
The site downloads the MLS data each day from two different MLS boards (North Tahoe and South Tahoe) via a Python script and converts the data into nodes(pages). It then notifies clients who have subscribed for updates. Notifications include; new listings that match their criteria, price changes, and when photos have been added/changed. It also has a weekly statistical email subscription that crunches some basic stats and includes link to new listings, price changes, and new/updated photos. On the property pages we display the following; listing date, property details (including HOA fees), listing agent's comments, a history of original price and dates of each price reduction, a slide show (via Google's Picasa) of additional photos we've taken, comments from us after we've previewed, Google Street view that has the ability to see the neighboring properties, Google map, a slide show (via Google's Picasa) of the HOA amenities, a table of recent sales in the community (uploaded via node import module), a table of recent price reductions in the community (automatically done via the MLS module), a table of properties in the community that we've recently previewed and added photos. In the side bar of each property page we include an area called Quick Links that includes; Search the MLS, Weekly market report, Lake Tahoe lakefront homes, Recent sales by area, Recent price reductions by area, Bank owned properties, Short sales, and another link to contact us. Below this the MLS module automatically crunches the following stats;

Below this we display featured properties. We currently have this configured to display properties within the same community that are priced similar to the property the client is viewing. This can also be set to display any properties....those we see as exceptional, those we've previewed, or our listings.
I get comments from new clients often saying they are contacting me because my site provides more information than any other site in my market. 99% of the sites are a framed IDX solution from a local developer. But there's more I want to do with the site. More stats, mapping search and results displays, better search engine optimization of the properties, multiple community sites that feed from the main site, integration with a CRM like salesforce.com, automation of the addition of the sold stats... I'm reaching out to other realtors in an attempt to see if we can get a few of us to collaborate on the details of the build as well as the cost of the build.
Take a look at the site and let me know what you think.
