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.
> The aforementioned web space, part of the SPAR Ontologies website, has been reserved for providing the RDF representation of each media type defined by IANA [3]. 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.
> Each media type can be accompanied by agents who acted as contributors, the related RFC documents documenting it, its current status (either official, deprecated or obsoleted), and direct links to Wikipedia pages and DBpedia resources related with the media type.
> All these resources defining media types, thus, can be used for specifying particular formats (e.g., by means of the DCTerms property dcterms:format) that a certain entity, such as a book or a dataset, can have.
