Idea

Basically,

Schema is much like a machine readable word-list rather than creating
sentences, that can the be checked for reputation (ie: do the claims make
sense once processed by search magic).

CONCEPTS
A site exists that allows someone to use a UI/UX to create mark-up.
They're able to use a series of RDF Statements to create a RDF 'sentence',
that may otherwise not be easily covered by the existing 'word-list'
provided by mark-up.

1. The ability to create concepts (and save them): ie: MedicalSpa = Place
(daySpa + medicalClinic), staffedBy (medicalPractitioner, beautyTherapist)
2.  The ability to use existing Concepts to add to records (ie:
medicalSpa + Location, Opening Times, etc.)
3. The ability to generate a URL/URI that acts as a schemaURI (triple) to
describe the whole concept.

Other examples;

NewsArticle
HistoricalDocument (place, about(wikidatalink pertaining to wikipedia
and/or other page on historical subjects)

In this way, it's a bit like an external CSS file.  User can either
download the generated file, or simply use the URI/URL in a document as
part of a triple to describe what the document is attempting to describe.

USE OF 'VERIFIABLE CLAIMS' (seeAlso:
https://www.w3.org/community/credentials )

The creator of concepts could 'sign' them, and they could be stacked.  Ie:
a publisher might create a statement that says it's a publisher, et.al.  A
journalist may have a statement that pertains to the publisher; and the
article may be authorized by the journalist.  In-effect you get 'concepts'
as 'verifiable claims', that can be used as elements to describe other
(broader) concepts (graphs) that may in-turn pertain to a multitude of
actors (ie: some medicalSpa association says that medicalSpa is a thing and
that the nominated 'subject/actor' is a member).

Other examples of similar concepts;
Google Services:
- Google My Maps: https://www.google.com/maps/d/ - allows a user to upload
a CSV file with stuff in it, then generate a URI to represent the custom
map.
- http://cse.google.com/  - Allows a user to generate a custom search
(inclusively to the use of schemaorg terms) then generate a public.

NOTE: TBL's argument the HTTP URIs (without "#") should be understood as
referring to documents, not cars.[1]

This would be a machine-readable document, however the underlying notion
it's providing is a set of machine-readable declarations about the document
it is intended to be asserted to.

CONSIDERATIONS

*REFERENCE DESIGN*
A reference design be produced that is available via GitHub as a
work-product of this group. I can see enormous benefits (including the
insertion of advertising and/or tracking codes) for commercial applications
of the concept; however i also think it's kinda important it's not produced
simply as a web 2.0 styled silo, and i'm as yet unsure of how interop
requirements may grow if the idea was successfully developed.

EXPORT OF CONCEPTS
Existing 'word-lists' in schemaorg (for instance) are based on discussions
and are slowly developed.  This tool may find that a particular concept is
readily used and therefore better added to the core 'dictionary' rather
than being a constructed concept[2].  This is similar to the manner in
which language develops in society, in that a concept ends-up getting added
to a dictionary[3].

TOOLS Document
For anyone who hasn't checked it out, or isn't aware - the Tools[4] Sheet
has been developing and contributions are welcomed.
