This will not work if I have web document about a web document. EARL is a good example here. In other words in RDF Topic Maps I can say: Uche: rtm:/indicatedBy <http://uche.ogbuji.net/>; :created [ rtm:/constitutedBy <http://uche.ogbuji.net/>; rtm:/indicatedBy <http://www.web-analysis.org/analysis-of-uche.ogbuji.net.html> ]. The part that would not work is the last 2 triples: You need to say rtm:/constitutedBy <http://uche.ogbuji.net/>; rtm:/indicatedBy <http://www.web-analysis.org/analysis-of-uche.ogbuji.net.html> In order to not confuse it with: rtm:/indicatedBy <http://uche.ogbuji.net/>; rtm:/constitutedBy <http://www.web-analysis.org/analysis-of-uche.ogbuji.net.html> > this is also being discussed on www-tag as the "range of HTTP > issue". It's a real practical problem, and something that we had > to get round in the EARL [1] project.

Aha! Looks like TimBL is also into Topic Maps into RDF mapping. Sad that Topic Maps are not being mentioned. Attempts 2 and 3 are just forms of Topic Maps baseName representation in RDF. Let me copy and paste... Attempt 2 <rdf:description> <rdf:type resource="http://www.people.org/types#person" /> <play:name rdf:parseType="Resource"> <rdf:value>Ora Yrjö Uolevi Lassila</rdf:value> <play:lang>fi</play:lang> </play:name> <play:mailbox resource="mailto:ora.lassila@research.nokia.com"/> <play:homePage resource="http://www.w3.org/People/Lassila"> </rdf:description> Attempt 3 <rdf:description> <rdf:type>http://www.people.org/types#person</a> <play:name> <lang:fi>Ora Yrjö Uolevi Lassila</lang:fi> </play:name> <play:mailbox>ora.lassila@research.nokia.com</play:mailbox> <play:homePage>http://www.w3.org/People/Lassila/</play:homepage> </rdf:description> And here is Topic Map: <topic> <instanceOf><topicRef xlink:href="http://www.people.org/types#person" /> <baseName> <scope><topicRef=http://www.topicmaps.org/xtm/1.0/language.xtm#fi/></scope> <baseNameString>Ora Yrjö Uolevi Lassila</baseNameString> </baseName> <occurrence> <instanceOf><topicRef xlink:href="#mailbox"/></instanceOf> <resourceRef xlink:href="mailto:ora.lassila@research.nokia.com"/> </occurrence> <occurrence> <instanceOf><topicRef xlink:href="#homePage "/></instanceOf> <resourceRef xlink:href="http://www.w3.org/People/Lassila"/> </occurrence> </topic> > [1] http://www.w3.org/2001/03/earl/ > [2] http://www.w3.org/DesignIssues/InterpretationProperties --Nikita.
