microdata

A proposed update to the W3C microdata specification.

This work aims to bring the specification in line with deployed implementations and publish it as a W3C Recommendation.

Substantive changes are documented in the specification, major technical changes include:

In the current editors' draft:

  • Clarify that microdata does not guarantee ordering of properties
  • Remove the conversion to JSON-LD

In the 10 October Working Draft:

  • Add a normative algorithm to convert microdata to RDFa
  • Add a normative algorithm to convert microdata to JSON-LD

Changes in previous Working Drafts include:

  • Remove the special unimplemented Drag-and-Drop functionality
  • Use itemtype as a vocabulary identifier.
  • Add a global content attribute as a mechanism to explicitly define property values
  • Allow data, meter and time elements to use their text content as a value.
  • Allow itemid more liberally.
  • Allow for the use of microdata in languages other than HTML
  • Remove the Microdata DOM API
