Hi Silvio,

Nice work: this could be handy.  I have a couple of questions/comments:

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

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

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.

> A media type is an identifier (for example "text/turtle") for file formats on the Internet composed by two parts: a registry ("text" in the example) and a record ("turtle" in the example). They are handled by the Internet Assigned Numbers Authority (IANA), which is the official authority for the standardisation and publication of these classifications.

In particular, a media type is accessible by concatenating the URL "http://www.sparontologies.net/mediatype/" with its related identifier. For instance, "http://www.sparontologies.net/mediatype/text/turtle" allows one to access the specific resource for the "text/turtle" media type.
