For content management systems written in PHP, the framework provides a <sparql> meta-tag that performs queries, generates HTML, and includes form information in a page to provide all of the functionality necessary for data-powered content editing. This tag can be included alongside custom content by performing preprocessing of a page in Drupal or MediaWiki.

There are three key components that work in concert to provide data-driven web content:1. Content generation
by query using XML stylesheets
2. Form construction using RDFa hints
3. Update propagation to backing triple store
Turning Data into Web-accessible Content
The Framework is designed to be platform independent, allowing organizations to move between different content management systems to meet their growing needs. Additionally, since content can be transformed into XHTML, one can embed content on pages external to the site, e.g. researcher CVs, making it easier to manage pages across many different sites. Our framework operates over common ontologies such as FOAF, Dublin Core, OWL Time, VOID, RSS, iCal, etc.
Benefits of RDFa
Data Portability and Reuse
RDFa embeds information about the structure of data into HTML pages, making it available for machines to use. For example, our system uses RDFa annotations to generate dynamic forms that allow users to edit the content of pages without needing to maintain two separate pages for each item (e.g., see right). Also, machine annotations can allow for smarter search over data, including the use of tools like faceted search and rich snippets, making it easier to disseminate information across the World Wide Web.
