Schema Markup Documents ie: .bot files

Had an idea.

The idea relates to the various ontology mark-up currently placed in-line
with a HTML document.  Problem is various agents want different formats /
different ontologies.

So,

HTML5 currently has a

.HTML
.js
.css

the suggestion is to add a .bot file (or other name - as that's not
consequential)

The intention is to improve support for schema by identifying what the
client is, much like the means CSS improves user-experience for 'style'.

In this way, if the 'agent' is FB - then OG tags; or search providers =
schemaorg, etc.

The external file would need to be linked to tags in the HTML doc; allowing
it to be flexibly parsed using various schema markup to suit different
agents.

Thoughts?
