Enhanced MetaTag Specification
07 Jul 2022 by Brandt Redd

Today I have updated the MetaTag Specification. The new spec, version 1.1, is backward compatible with version 1.0. It has the following enhancements:

  • MetaTags (without prefixes) are explicitly from the schema.
  • A regular expression is given that can be used to find metatags embedded in text.
  • A namespace prefix may be used to specify another schema.
  • It explicitly states that repeated MetaTags should be interpreted as a list of values for the same property - but only when the property definition accepts a list.
  • Design goals are given along with discussion about why I made certain design decisions.
  • An experimental design for hierarchical data models is included.
