Yep, so we must do this.

Ah. That is interesting although… I am not sure it is relevant in terms of the review of these specs. The horizontal review is really to assess whether the documents abide to the requirements of accessibility.

That is also interesting… do you think it would be possible to provide some schema specific metadata samples for various sub-vocabularies of schema? Then people may use a csv file to describe the data and trust some conversion to, say, JSON-LD. That may be interesting...

Beyond DWBP a big yes for other govt lists. Leave that to Jeni & Rufus...

That is correct; I am not sure how of us could/should write that.

I think it would be a stretch to bind it to R2RML. The whole idea of URI template makes it very different, there is nothing like that in R2RML. Also, R2RML (or the Direct Mapping) do not have any notion of validation of the data, which is a very important part of what we have done.

Note, however:

https://github.com/w3c/csvw/issues/455

showing that it is easy to reproduce, for a specific csv file, the Direct Mapping output with a suitable metadata file. If that approach works, it could be an important part of our answer to this.

The short answer is: no. But that falls under the issue that we have no XML mapping in the first place. And, at this stage, we are sure there won't be….

(B.t.w., the XFOrms WG has been closed, afaik…)

Yeah. It is unfortunate that Yakov is not active any more; I wonder whom we could contact on this (if there is anybody still active on this)

We are ahead of schedule:-) the documents are ready on our site, and the request to the webmaster has been sent!
