Getting structured data to RDF: GRDDL

• GRDDL is a way to access structured data in XML/XHTML and turn it into RDF:

• • defines XML attributes to bind a suitable script to transform (part of) the data into RDF
  • • script is usually XSLT but not necessarily
    • has a variant for XHTML
  • a “GRDDL Processor” runs the script and produces RDF on–the–fly

• A way to access existing structured data and “bring” it to RDF

• • eg, a possible link to microformats
  • exposing data from large XML use bases, like XBRL
