<foaf:Person about="#someone">
	<wot:inverseOfIdentity>
		<wot:PubKey>
			<wot:fingerprint>645D 8055 B685 E0EC 3B0B  B507 3B29 6D51 CC18
5A3B</wot:fingerprint>
		<wot:PubKey>
	</wot:inverseOfIdentity>
</foaf:Person>

<foaf:Person about="#somebody">
	<wot:inverseOfIdentity>
		<wot:PubKey>
			<wot:fingerprint>645D 8055 B685 E0EC 3B0B  B507 3B29 6D51 CC18
5A3B</wot:fingerprint>
		<wot:PubKey>
	</wot:inverseOfIdentity>
</foaf:Person>

To be able to conclude that #someone owl:equals #somebody I think the
following would be needed:
1. wot:inverseOfIdentity should exist
2. wot:inverseOfIdentity should be an InverseFunctionalProperty
3. wot:fingerprint should be an InverseFunctionalProperty

While I assume the first two not to be two controversial....
just reread http://rdfweb.org/topic/TrustVocabIssue and saw that the
hex_id is to small not the fingerprint, so I see no problem with 3.

Cheers,
Reto
