Re: Extension for schema.org/Skiresort

I have doubts this thread is useful, but what Dan is referring to is e.g.

- Simple HTML Ontology Extensions (SHOE), developed ca. 1996
- Meta Content Framework (MCF), developed between 1995 and 1997
- Work done under the "global schema" theme in database research in the 1980s and 1990s
(try https://scholar.google.de/scholar?q=global+schema&hl=en&as_sdt=0%2C5&as_ylo=&as_yhi=1990)

etc.

Schema.org is based on paradigms and ideas of the Semantic Web vision and its predecessors without being tied to the details of the W3C implementation of the W3C vision. A main innovation of schema.org was that it abandonend the idea of fully decentralized ontology design ("ontology alignment at consumption time") in favor of a centralized approach ("ontology alignment at ontology engineering time"), mainly motivated by the fact that Web masters need some kind of guidance of which vocabularies are actually considered by mainstream consumers of data.

Microdata brought some valuable ideas to the development, like the notion that usage and visibility of data increases its quality, but it would really be a stretch to say that microformats are the direct predecessor of schema.org.
