Survey for media-type evolution

Dear Semantic Web community,

TL/DR: do your RDF tools encounter problems when loading the following 
resources?

As many of you know, the W3C RDF-Star Working Group [1] is currently 
extending the RDF abstract syntax and the corresponding serialization 
formats. A long standing question that we have to respond is whether we 
should change the media types of the formats, or keep them for the new 
versions of the format [2,3].

A middle-way was discussed yesterday by the Working Group [4], 
consisting in adding a 'version' parameter to the media-types, e.g. 
'text/turtle;version=1.2'. The goal of this email is *not* to discus the 
merits and drawbacks of this approach, but to check an assumption that 
some of us have, namely:

     Despite the fact that the current media-types do not support the 
version parameter currently, its presence will be gracefully ignored by 
current implementation.

To test this hypothesis, I have added such a version parameter on 
different versions of my own FOAF profile, and I have checked that the 
following tools load from these URLs without any trouble:

- sophia-cli (https://github.com/pchampin/sophia-cli)
- rapper 2.0.16 (https://librdf.org/)
- Jena RIOT 5.2.0 (https://jena.apache.org/)
- Ruby RDF command line tool 3.3.2 (https://ruby-rdf.github.io/)
- Python RDFlib 7.1.1 (https://rdflib.readthedocs.io/en/stable/ -- via 
the method Graph.parse)

It would be great if we could collectively extend this list, to assess 
how disruptive (if at all) the use of the 'version' parameter would be 
on legacy implementations. Please respond to this email with your own 
experiment.

   thanks in advance,
   pa


PS: let me emphasize again that, if you want to discuss the pros and 
cons of this solution, you should contribute to [3], but do *not* do it 
in response to this email, to keep the thread focus on the survey itself :)
