Re: SHACL and SHACLC mime types

Hi Vladimir,

I am glad to hear you find SHACLC useful. You may be aware that we 
rushed this through the door in the final days of the original data 
shapes WG but it then didn't become an "official" deliverable by that 
WG. Instead it became input to the Community Group where this mailing 
list is for. The current draft is at

https://w3c.github.io/shacl/shacl-compact-syntax/

I am mentioning this because I believe it might be best if someone else 
than me takes it over. I have my name already on 3 other SHACL-related 
docs and cannot do justice and give the Compact Syntax the attention 
that it deserves. I don't want to be an obstacle.

So if someone else wants to take it over or join as first or second 
editor I'd be very happy to take a back seat. If someone else drives 
this, we could also reopen the syntax and modify it to cover more use 
cases. Nothing here is cast into stone, consider this a "living" 
standard. This also includes the IANA registration.

What are your thoughts?

Regarding the specific mime type question, text/shaclc with .shaclc 
sounds good to me. I don't really think the others need specific mime 
types as there is no such things as a pure SHACL Turtle file IMHO. It's 
usually SHACL mixed with some parts of RDFS and other properties such as 
rdfs:comment.
