Topic map is basically a graph where topics are nodes and associations edges between nodes. A topic is a reification of it's subject and the subject is expressed using URIs. A topic has always one subject identifier URI but the number of subject identifier URIs is not limited to one. Sometimes it is convenient and even necessary to attach several subject identifier URIs into a topic. Linked data is a movement in computing that bridges URIs that should be thought as same. Sameas.org is a linked data web service that stores and distributes URIs linked with the sameness relation. For example, the sameas.org service can be requested for URIs that are same as http://dbpedia.org/resource/Edinburgh . The response contains more that 170 linked URIs.
Wandora's Sameas subject expander is tool that is used to retrieve all linked URIs from the sameas.org service and attach retrieved URIs into the given topic. Usually the effect is that the number of topic's subject identifiers is increased. The effect suggests that topic's subject expands.
Notes
- The sameas.org doesn't contain all possible URIs but a curated set of URIs. Thus, the user is using her own URI vocabulary, the subject expander may have no effect at all.
