Here are some snippets of XML Topic Map syntax, representing my
modelling of delicious bookmarks. Note that a topic map is the model,
XTM is merely an exchange format (bit like a relational model versus a
csv file).
<association>
 <instanceOf>
 <topicRef xlink:href='#bookmark'/>
 </instanceOf>
 <scope>
 <topicRef xlink:href='#rob'/>
 </scope>
 <member>
 <roleSpec>
 <topicRef xlink:href='#resource'/>
 </roleSpec>
 <topicRef xlink:href='#microformats_org'/>
 </member>
 <member>
 <roleSpec>
 <topicRef xlink:href='#tag'/>
 </roleSpec>
 <topicRef xlink:href='#microformats'/>
 </member>
 </association>
Here the resource topic referred to in that association:
 <topic id='microformats_org'>
 <instanceOf>
 <topicRef xlink:href='#resource'/>
 </instanceOf>
 <subjectIdentity>
 <resourceRef xlink:href='http://microformats.org/'/>
 </subjectIdentity>
 <occurrence>
 <instanceOf>
 <topicRef xlink:href='#title'/>
 </instanceOf>
 <scope>
 <topicRef xlink:href='#rob'/>
 </scope>
 <resourceData>microformats blog</resourceData>
 </occurrence>
 <occurrence>
 <instanceOf>
 <topicRef xlink:href='#description'/>
 </instanceOf>
 <scope>
 <topicRef xlink:href='#rob'/>
 </scope>
 <resourceData>pave cow paths</resourceData>
 </occurrence>
 </topic>
The Linear Topic Map Notation (LTM) is much more concise, so I'll show
more topics and bookmarks:
/* topic types */
[resource @"http://www.w3.org/1999/05/WCA-terms/01#Resource2"]
[tag @"http://dublincore.org/documents/dces/#subject"]
[user @"http://www.w3.org/1999/05/WCA-terms/01#User"]
/* occurence types */
[title @"http://dublincore.org/documents/dces/#title"]
[description @"http://dublincore.org/documents/dces/#description"]
/* association types */
[bookmark @"http://del.icio.us/post/"]
/* topics */
[rob : user @"http://del.icio.us/rob"]
[bud : user @"http://del.icio.us/bud"]
[microformats_org : resource %"http://microformats.org/"]
[microformats : tag @"http://del.icio.us/tag/microformats"]
[web : tag @"http://del.icio.us/tag/web"]
/* topic occurrences */
{microformats_org, title, [[microformats website]]} / bud
{microformats_org, title, [[microformats blog]]} / rob
{microformats_org, description, [[pave cow paths]]} / rob
/* bookmark associations */
bookmark(microformats_org, microformats) / bud
bookmark(microformats_org, microformats) / rob
bookmark(microformats_org, web) / rob
Cheers,
