Validation of Expressed Micro-data
USE CASE: Expose machine-readable documentation of micro-data
vocabularies so generalized validators and authoring tools can be
* Echo would like to write a generalized software tool to help page
authors express micro-data. One of the features that she would
like to include is one that displays authoring information, such
as vocabulary term description, type information, range
information, and other vocabulary term attributes in-line so
that authors have a better understanding of the vocabularies that
* Thundercleese would like to ensure that his indexing software

* Originating vocabulary documents should be discoverable.
* Machine-readable vocabulary information shouldn't be on a
separate page than the human-readable explanation.
