Schema.org, Enumerations and Wikidata proposal

There are many 'lists' or 'enumerations' (such as the list of countries,
languages, ...). Often, markup wants to refer to items from such lists.
Since we have the corresponding types, pages can refer to them via
descriptions (e.g., 'a country with the name xxx'). It would be useful to
have canonical lists of urls for items on these lists to help with
reconciliation, etc.

 The proposal is to periodically (with every schema.org release) import
particular lists from Wikidata into 'lists.schema.org'. So, '
lists.schema.org/Language/Tamil <http://lists.schema.org/TamilLanguage>', '
lists.schema.org/Country/Mexico <http://lists.schema.org/MexicoCountry>',
etc. Along with each item (such as lists.schema.org/MexicoCountry), we
should also import a set of attributes/relations from Wikidata so that we
have a description of the node, which can help with recon using reference
by description. It will also include a sameAs link to the corresponding
Wikidata item.

 Schema.org will also suggest the use of Wikidata as a common, canonical
entity repository for targets of the sameAs relation.
