Should dc:format not be "image/svg+xml" ?

cnt:charEncoding  should be cnt:characterEncoding  - it is useful to
keep this property as an agent who needs to save the SVG to file for
further processing would know which character encoding to use and not
be in conflict with any character set declared within the XML.

Using instead cnt:ContentAsXML
http://www.w3.org/TR/Content-in-RDF10/#ContentAsXMLClass would avoid
character set issues; but would generally only be useful if your
primary RDF format is RDF/XML.

Yes, this would make sense; specially when <pageURL> contains more
than just the HTML for viewing the video (such as comments, related
videos, a playlist)
