The Meta-Content Framework and Apple HotSauce

The Meta-Content Framework (previously “Format”), developed in 1996–7, was a structured data format for knowledge representation, typically used to describe the content of a website. This site is an archive of material about MCF, and HotSauce, Apple Computer’s graphical interface to MCF. The pages have been cleaned up, but a link to the original as captured in the Internet Archive is on each.

MCF was superseded by the Resource Description Framework (RDF). For information on how the transition from MCF to RDF happened, see Tim Bray’s history of RDF (2003).
