The RDF Model and Syntax Specification became a W3C Recommendation nine years ago today!
Resource Description Framework (RDF)
Model and Syntax Specification
W3C Recommendation 22 February 1999
Best wishes to all members of the original W3C RDF Model and Syntax Working Group and to all those who have built on top of the foundations we created.
Seems like only yesterday 😉
