CMS for publishing Linked Data with the 303 URI method

Question

I’m looking for a CMS that allows to publish Linked Data (RDF) out of the box.

As a solution for the httpRange-14 issue, it MUST use the 303 URI method:

It’s, for example, used by the DBpedia:

1. The URI http://dbpedia.org/resource/The_Lord_of_the_Rings (…/resource/…) represents the thing.
2. When visiting this URI, you get HTTP status code 303 See Other.
3. Now content negotiation redirects you to your preferred representation, i.e.,
   1. http://dbpedia.org/page/The_Lord_of_the_Rings (…/page/…) if you prefer HTML
   2. http://dbpedia.org/data/The_Lord_of_the_Rings (…/data/…) if you prefer some RDF serialization

Bonus: Allow different RDF serializations, e.g. /data/The_Lord_of_the_Rings.xml (for RDF/XML), /data/The_Lord_of_the_Rings.turtle (for Turtle) etc. The additional serializations should, of course, be generated/converted automatically.

I have no specific requirements about how to add data.
I’d prefer a GUI that allows to enter triples, preferrably with auto-completion of internal URIs/CURIEs and external vocabularies.

The HTML representation should be auto-generated from the RDF data, allowing to browse to related documents and values of triples.

Formal requirements

• It MUST be FLOSS.
• It MUST run natively on a GNU/Linux server.

(Personally, I can’t use a Java-based solution, but please recommend them nonetheless as others might be interested.)

Answer 1

If an automated system is acceptable, then Walder seems a quite decent option.

It requires Node.js (not Java). It is Free Software (using liberal Mit/Expat license).

It does not provide a GUI, however - so if that is what you imply when requiring a "CMS" then unfortunately this is not adequate.
