Align with schema.org terms

Ellis Pratt has suggested aligning our document types with https://schema.org terms.

Schema.org maintain and promote schemas for structured data on the internet. In particular, they provide tags which we probably should be incorporating technical documentation. It was founded by Google, Microsoft, Yahoo and Yandex and using this apparently increases search indexes.

What do others think about including these tags into our templates?

Any ideas on how we would incorporate such tags into Markdown? Or some other wiki?

Possible alignment with our 0.1 templates:
