Hi Graham,

> Nice work: this could be handy.  

Thanks :-)

> 1. I assume the machine formats are accessible by content negotiation?  

They are accessible by content negotiation indeed. In particular, one can use:
- "application/rdf+xml" for having the data in RDF/XML;
- "text/turtleĒ or "text/n3" for having the data in Turtle;
- "application/ld+json" or "application/json" for having the data in JSON-LD;
- any other kind of request will result in having the data in HTML.

E.g.:

> curl -L -H "Accept: application/rdf+xml" http://www.sparontologies.net/mediatype/text/plain <http://www.sparontologies.net/mediatype/text/plain>

will return the RDF/XML representation of such media type.

> It might be handy to also include direct links on the web page.  For example, I found I could change the .html suffix to .ttl or .json to get alternative representations, but that required guesswork on my part.

Thatís right, you can access directly to the related formats by adding .rdf, .ttl, .json and .html respectively. Iíll add a note in the homepage of the dataset and in each HTML page of each mime type soon.

> 2. Are there any plans (and resources) in place to ensure longevity of the sparontologies.net domain?

Well, actually now the sparontologies.net <http://sparontologies.net/> website is handled by me, with personal resources. I would like to keep it available without external funds, but in case it will be more expensive to maintain I think I can ask for support to the University of Bologna, thatís the plan at least. Do you have something different in mind?

> 3. I note that the HTML page indicates cc-by licensing of the content, but there is no such information in the machine readable formats.

Thatís right, I have to add these data into the RDF representation as well Ė in my todo list.

Have a nice day :-)

S.
