Semantic Web Metadata (RDF, RDFa)


“The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources; using a variety of syntax formats.” - Wikipedia


“[Simple] Wikipedia does not yet have an article with this name.” - Simple Wikipedia


RDF, Really

“Triple” statements.<Fred> <is giving> <a talk on RDF>.<This work> <is licensed> <under CC BY>.

Serialized XML fileLike RSS, sort of.

Vocabularies to describe anything Using URIs

Some Microformats are RDF, but not all.Saturday, June 20, 2009

RDFa

The “a” is for “attribute”Using XHTML meta and link attributes.

A good compromise with the goals of Microformats

Now a W3C RecommendationccREL is expressed in RDFaGoogle, Yahoo, MySpace, Digg, etc.

RDFa FAQ

dc:title/dc:type

dc is Dublin Core Title, Author, Type, etc.

The inner HTML of the tag is “RDFa FAQ” which is the title of the work.

This is a text document, so we point dc:type to the Dublin Core definition for "Text" using the rel tag.

Another document Type that could be specified with the href is http://purl.org/dc/dcmitype/StillImage or http://purl.org/dc/dcmitype/Sound, depending on the medium being licensed.


http://purl.org/dc/elements/1.1/

http://purl.org/dc/dcmitype/Text

http://purl.org/dc/dcmitype/StillImage




http://purl.org/dc/dcmitype/Sound

http://purl.org/dc/dcmitype/Sound

<a xmlns:cc="http://creativecommons.org/ns#" href="http://www.example.com" property="cc:attributionName" rel="cc:attributionURL">John Doe</a>

cc:attributionName/cc:attributionURL

CC is using its own XML namespace, abbreviated using cc:

The property is CC's AttributionName attribute, the value is the content inside the anchor tag (in this case, the fictitious John Doe), and a relationship of cc:AttributionURL is defined as being http://www.example.com.


http://creativecommons.org/ns#


http://www.example.com

<a rel="license" href="http://creativecommons.org/licenses/by-sa/3.0/us/">Creative Commons Attribution-Share Alike 3.0 United States License</a>.

rel="license"

Most basic and fundamental part of CC's usage of RDFa

Always included in the HTML offered, regardless of whether users fill out the "Additional Information" section.

The rel specifies the relationship of the href's URL. In this case, the relationship is "license" and the URL is a standard Creative Commons license.


http://creativecommons.org/licenses/by-sa/3.0/us/

http://creativecommons.org/licenses/by-sa/3.0/us/

Based on a work at <a xmlns:dc="http://purl.org/dc//" href="http://wiki.creativecommons.org/RDFa" rel="dc:source">wiki.creativecommons.org</a>

dc:source

Similar to dc:title, dc:source specifies where the original source of the file is located.

Flickr does this and its awesome.

In this case it is pointing to http://wiki.creativecommons.org/RDFa




http://wiki.creativecommons.org/RDFa

Permissions beyond the scope of this license may be available at <a xmlns:cc="http://creativecommons.org/ns#" href="http://moreperms" rel="cc:morePermissions">http://moreperms</a>.

cc:morePermissions

Part of the CC+ protocol, creators can specify a URL where re-users of CC licenses can obtain more rights to the work.

Here, the nonexistent URL of http://moreperms is used as a placeholder.

Try Ogg Player Fall Back to Flash Player

Firefox 3.5, Chrome natively supports Ogg + <video> within HTML5

Safari, IE? Anyone?

Push to default YouTube to OGV instead of H.264 No good excuse from Google.
