From the post:
Summary: RDFa 1.1 Lite is a simple subset of RDFa consisting of the following attributes: vocab, typeof, property, rel, about and prefix.
During the schema.org workshop, a proposal was put forth by RDFa’s resident hero, Ben Adida, for a stripped down version of RDFa 1.1, called RDFa 1.1 Lite. The RDFa syntax is often criticized as having too much functionality, leaving first-time authors confused about the more advanced features. This lighter version of RDFa will help authors easily jump into the Linked Data world. The goal was to create a very minimal subset that will work for 80% of the folks out there doing simple markup for things like search engines.
I was struck by the line “…that will work for 80% of the folks out there doing simple markup for things like search engines.”
OK, so instead of people authoring content for the web, the target of RDFa 1.1 Lite targets 80% of SEOs?
Targeting people who try to game search engine algorithms? Not a terribly sympathetic group.
