RDF and Resources
RDF's definition of resource seems to be incompatible with the URI specification that it references: > All things being described by RDF expressions are called resources. > A resource may be an entire Web page; such as the HTML document > "http://www.w3.org/Overview.html" for example. A resource may be a > part of a Web page; e.g. a specific HTML or XML element within the > document source. A resource may also be a whole collection of pages; > e.g. an entire Web site. A resource may also be an object that is > not directly accessible via the Web; e.g. a printed book. Resources > are always named by URIs plus optional anchor ids (see [URI]). According to RFC 2396, a resource is something addressable by a URI (without fragment identifier) -- a complete HTML or XML document, not a part of it. Also, I find it interesting to note that RDF does not seem to be able to attach metadata to components of things that are not XML: frames of a video, records in a database, paragraphs in a Word document and so forth. We need the ability to do so. -- Paul Prescod - ISOGEN Consulting Engineer speaking for only himself http://itrc.uwaterloo.ca/~papresco "Silence," wrote Melville, "is the only Voice of God." The assertion, like its subject, cuts both ways, negating and affirming, implying both absence and presence, offering us a choice; it's a line that the Society of American Atheists could put on its letterhead and the Society of Friends could silently endorse while waiting to be moved by the spirit to speak. - Listening for Silence by Mark Slouka, Apr. 1999, Harper's xml-dev: A list for W3C XML Developers.
