Ed Knutson’s job is to get those sites talking to each other, even though the content may be in different languages (English, Spanish, Arabic, etc.) and created with different content management systems, or CMSs, such as Drupal or Wordpress. The Global Square network will connect not through those systems but through “semantic Web” standards designed to link up disparate technologies.
One key standard has the wordy name Resource Description Framework, or RDF, a universal labeling system.
If an occupier wants to post the minutes of a meeting, for example, they might type them in the appropriate text box in the content management software running the site. That software pushes the information to an RDF database and tags it with some universal label – it could be called “minutes” or any other term that all the occupations agree on. The local occupier might also select “Group: Alternative Banking” from a dropdown list, and that label would be added as well. Using the same labels allows all the sites to trade information. So a search for minutes from an Alternative Banking group would pull up records from any occupation with that kind of group.
With RDF, sites can work together even if they run on different content management software, such as Drupal (as in the FGA) or Wordpress (as in the Spanish M15 group).
“The handoff point is that everything goes through RDF,” said Knutson. “You don’t care if they have a Drupal site or some kind of Frankenstein combination of different stuff.”
The problem the coders face will be the same one that’s faced the web for years – getting people to agree on standards and to then adopt them. One long-running attempt to do this quickly is called Microformats – a way of including markup data in HTML that’s invisible to an human visitor, but which can be understood by their browser or by a search engine. Examples include marking up contact information so that a reader can simply click contact information to add it to their address book and annotating a recipe so that search engines can let you search for recipes that include ’spinach’.
