CSV on the web support

[Floppy]

From @JeniT:

Specs are at:

http://w3c.github.io/csvw/syntax/
http://w3c.github.io/csvw/metadata/

The examples at:

http://w3c.github.io/csvw/csv2json/#examples

are particularly useful.

There are tests are described at:

http://www.w3.org/2013/csvw/tests/

and are in Github at:

https://github.com/w3c/csvw/tree/gh-pages/tests

There’s a manifest in JSON at:

https://github.com/w3c/csvw/blob/gh-pages/tests/manifest.jsonld

which points to the manifest for the validation tests (which are the only ones I think we have to care about) which is at:

https://github.com/w3c/csvw/blob/gh-pages/tests/manifest-validation.jsonld

Creating something that maps that test manifest into whatever format tests are needed for csvlint would be good.

I suspect that you will want to distinguish between validation based on datapackage and validation based on CSV on the Web metadata: there are many similarities but they’re not identical.

I have started to implement this in the feature-csvw-validation branch
