4 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu Friend of a Friend FOAF -- currently, probably the most widespread application of RDF –http://www.foaf-project.org/http://www.foaf-project.org/ The next several examples taken from Edd Dumbill's "Finding Friends with XML and RDF" –http://www.ibm.com/developerworks/xml/lib rary/x-foaf.htmlhttp://www.ibm.com/developerworks/xml/lib rary/x-foaf.html

14 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu Autodiscovery for FOAF In the head of your.html file: <link rel="meta" type="application/rdf+xml" title="FOAF" href="foaf.rdf" /> Example: http://www.w3.org/People/EM/http://www.w3.org/People/EM/ <link rel="meta" type="application/rdf+xml" title="Contact" href="contact" /> Link to: http://www.w3.org/People/EM/contacthttp://www.w3.org/People/EM/contact See: http://wiki.foaf-project.org/w/Autodiscoveryhttp://wiki.foaf-project.org/w/Autodiscovery

15 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu Xhtml Friends Network FOAF is either done with separate RDF files, or integrated into the HTML with RDFa with and tags XFN is a simpler, albeit lower fidelity approach to the same thing by using the "rel" attribute in or elements –next several examples from: http://gmpg.org/xfn/http://gmpg.org/xfn/ –an example of "microformats" -- the bottom-up contrast to RDF http://microformats.org/

16 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu XFN Example from: David wrote about a new theory... to: <a rel="colleague met" href="http://d.example.com/2003/11/08.html#T2134"> David wrote about a new theory... In HTML, rel can take multiple space separate values. In Atom, rel can only take a single value.

17 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu More Precision David wrote about a new theory...

18 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu 18 Different rel Types… http://gmpg.org/xfn/11 perhaps the most interesting: rel="me" useful for linking to other versions of "me" at different sites…

20 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu Google Social Graph API What kind of services can we build on the various FOAF & XFN links out there? Google Social Graph –http://code.google.com/apis/socialgraph/http://code.google.com/apis/socialgraph/ –next several examples taken from the above website See also Yahoo's SearchMonkey –http://developer.yahoo.com/searchmonkey/smguid e/profile_vocab.htmlhttp://developer.yahoo.com/searchmonkey/smguid e/profile_vocab.html

21 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu Mining me links XFN rel="me" links FOAF converted to me : –elements: weblog, homepage, openid, mbox_sha1sum –links:.html to.rdf others: –foaf:knows --> xfn:contact –more info: http://code.google.com/apis/socialgraph/docs/edg es.html http://code.google.com/apis/socialgraph/docs/edg es.html

22 ODU CS 751/851 Spring 2010 Michael L. Nelson mln@cs.odu.edu The Social Graph API http://socialgraph.apis.google.com/ ? & & Where the possible methods are: lookup: low-level access to the graph. otherme: given one or more of a person's identifiers (e.g. URLs), return other identifiers for that person. testparse: test your site's XFN or FOAF to see what the Social Graph API's parsers find in it
