[edit] Self-reference

Per Avoid self-references, should this article really link to an RDF dump of Wikipedia's contents (under the "RDF Files" section)? – Minh Nguyễn (talk, contribs) 04:20, 27 July 2006 (UTC)

It is an example of self-reference, but much milder than the examples given in Wikipedia:Avoid self-references. Its removal would not detract much. If you feel bothered by it, remove it. cygri 20:12, 11 February 2007 (UTC)
I am removing it. However, Example 2 is more serious self-reference problem and should be removed if someone can write a good second example (I don't have the technical knowledge of RDF to do it); the first simple one is not enough. However, there is a world of examples to choose from, which makes a WP article a particularly poor choice. One reason for the Wikipedia:Avoid self-references policy is that it makes WP look amateurish and therefore less authoritative. EB doesn't do it in the many articles where it could use itself as an example. Finell (Talk) 21:33, 17 February 2007 (UTC)
Is there an external reference that uses Wikipedia as RDF somehow? Drf5n 15:48, 2 November 2007 (UTC)

[edit] Planet RDF

I added a link to planetrdf.com since that site really is the hub of all RDF-related development. Subsequent edit took it out citing policy against linking to blogs. I'd contest that - planetrdf.com is an aggregator for RDF-related news and is central to the RDF community. Omitting it seems detrimental to this article. – Ian Davis

The site was described as a blog aggregator, and per Wikipedia:External links blogs are normally to be avoided. If you feel that this link is important, I won't oppose you adding it again, but I would appreciate it if you would explain here in some detail how it is important to the article. That would also help if somepne else comes along and also sees that it is a blog. -- Donald Albury 01:10, 5 September 2006 (UTC)
Here comes someone else in support of Ian, and re-insertion of the link to Planet RDF. RDF community is a reality, and Planet RDF is a hub for this community. I understand why links to blogs should generally be avoided (they often provide non-neutral, biased or extreme viewpoints), but since Planet RDF is aggregating many blogs, this makes for multiplicity of viewpoints. universimmedia 07:36, 5 September 2006 (UTC)
(Disclosure: Ian Davis, universimmedia, and me are all syndicated at Planet RDF.) Is a blog search engine a blog? No. Neither is a blog aggregator. The link should be in the article. Planet RDF is the most substantial source of RDF-related news and includes almost all of the important voices of the RDF community, including several members of the W3C's working groups that have developed RDF. The policy cited above explicitly does not apply to sources “written by a recognized authority”. Since Planet RDF is an aggregator of more than 50 sources, it is very different in nature from a single-author blog, and I do not see how the cited policy applies. (I leave it to someone else to re-add the link because of the obvious conflict of interest.) cygri 20:07, 11 February 2007 (UTC)

[edit] RDF data model vs. RDF/XML syntax

The article should discuss the difference between the RDF data model (a.k.a RDF Abstract Syntax) and the RDF/XML syntax. As it stands, the article mostly discusses the data model, but the file format infobox refers to the RDF/XML syntax, and the term RDF/XML is used throughout the article without the necessary introduction. cygri 09:05, 13 March 2007 (UTC)

[edit] Can't Add References?

I've attempted to add a reference in the Criticism of RDF section but the wiki is not creating a reference section. Can anyone fix this?Clan-destine 23:53, 11 June 2007 (UTC)

The filling-in of the references section is automatic, but you still have to create a stub for it. I just created one by adding the following to the article, above the "See also" section:
==References==
{{subst:Reflist}}
The Reflist template fills in the actual code, the crucial bit of which is <references/> —mjb 02:31, 12 June 2007 (UTC)

[edit] other examples

I'm new to RDF, but it seems this is another way of expressing a function based relationship. Given the article's example:

<http://en.wikipedia.org/wiki/Tony_Benn> <http://purl.org/dc/elements/1.1/publisher> "Wikipedia"

it could be expressed as y = f(x):

"Wikipedia" = http://purl.org/dc/elements/1.1/publisher( http://en.wikipedia.org/wiki/Tony_Benn )

and since y = f(x) is commonly expressed in various ways in computer code, wouldn't an example like this be useful in helping convert specialized jargon to a mathematical-like language that transcends written language, such as English?

[edit] Literals in subject position

RDF does not allow literals to occur in subject position. Therefore the very first example of this article stating that "the sky" is blue cannot be expressed in this way. Instead one would have to associate a URI with the concept "sky". I don't want to mess up the introduction, but this should be corrected. Brezenbene 16:31, 2 November 2007 (UTC)

Well it says a 'subject denoting "the sky" '... so it is not false, actually. But a little confusing, because one might think of literals. I guess we can delete my comment above. Brezenbene 16:34, 2 November 2007 (UTC)

[edit] Added Notes and rearranged references

I added a Notes section to gather footnotes and moved the W3C links into the references section. StephenReed 17:05, 26 March 2008 (UTC)
