Semantic Web Metadata (RDF, RDFa) Saturday, June 20, 2009

“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 Saturday, June 20, 2009

“[Simple] Wikipedia does not yet have an article with this name.” - Simple Wikipedia Saturday, June 20, 2009

RDF, Really “Triple” statements. <Fred> <is giving> <a talk on RDF>. <This work> <is licensed> <under CC BY>. Serialized XML ﬁle Like 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 Recommendation ccREL is expressed in RDFa Google, Yahoo, MySpace, Digg, etc. Saturday, June 20, 2009

Based on a work at <a xmlns:dc="http://purl.org/dc/terms/1.1/" href="http:// wiki.creativecommons.org/RDFa" rel="dc:source">wiki.creativecommons.org</a>. 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>. Saturday, June 20, 2009

dc:title/dc:type RDFa FAQ  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. Saturday, June 20, 2009

cc:attributionName/cc:attributionURL <a xmlns:cc="http://creativecommons.org/ns#" href="http://www.example.com" property="cc:attributionName" rel="cc:attributionURL">John Doe</a>  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. Saturday, June 20, 2009

rel="license" <a rel="license" href="http://creativecommons.org/licenses/by-sa/3.0/us/"> Creative Commons Attribution-Share Alike 3.0 United States License</a>.  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. Saturday, June 20, 2009

dc:source 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>  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  Saturday, June 20, 2009

cc:morePermissions 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>.  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.

File Metadata (XMP, Ogg, etc.) Saturday, June 20, 2009

liblicense  Low-level license metadata integration for applications.  Features:  Extract and write license information for files  Supports enumeration of available licenses  Wraps internationalized license information for Creative Commons licenses  Bindings for dynamic languages (currently Python and Ruby)  Extensible support for file types using module system  No specific GUI library dependency allows applications to build the graphical chooser most appropriate for their platform.  FLAC, MP3, XMP, Ogg, GSF.

How C Uses Open Video & Metadata Saturday, June 20, 2009

Try Ogg Player Fall Back to Flash Player <video src="http://player.uncensoredinterview.com/e/11222.ogv" controls width="384" height="216"> <object type="application/x-shockwave-flash" width="384" height="216" data="http://player.uncensoredinterview.com/e/11222.swf"> <param name="movie" value="http://player.uncensoredinterview.com/e/ 11222.swf"></param><param name="allowfullscreen" value="true"></param> </object> </video>  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. Saturday, June 20, 2009
