Hi all, David, I know you already know my personal view of this stuff with our recent private interactions & on the umbel mailing list. For the LOD mailing list readers, here is the background for this conversation: http://groups.google.com/group/umbel-ontology/browse_thread/thread/6bd977e50e1f372b Matthias suggested to used rdfs:seeAlso. I think it would make sense to createa subproperty of this property for that kind of purpose. In UMBEL we created a property that "is like" owl:sameAs, but that doesn't entail as much as sameAs does. *I am not suggesting* to use it for this specific use case, but *I would* suggest it to use it instead of owl:sameAs when "automatic" linkage is done between two datasets where issues can arise. This property is called "umbel:isLike" and come from the UMBEL ontology here: http://umbel.org/ontology/umbel.n3 The umbel:isLike property is described as: "he property umbel:isLike is used to assert an associative link between similar individuals who may or may not be identical, but are believed to be so. This property is not intended as a general expression of similarity, but rather the likely but uncertain same identity of the two resources being related. This property can and should be changed if the certainty of the sameness of identity is subsequently determined. In general, we may not be able to assert that two individuals are the same based solely on current information on hand. However, there may be quite reasonable bases or methods that the two individuals are likely the same without being one hundred percent sure. umbel:isLike has the semantics of likely identity, but where there is some uncertainty that the two resources indeed refer to the exact same individual with the same identity. Such uncertainty can arise when, for example, common names may be used for different individuals (e.g., John Smith). It is appropriate to use this property when there is strong belief the two resources refer to the same individual with the same identity, but that association can not be asserted at the present time with certitude." Hope this helps this conversation, and helps to extends the "owl:sameAs" conversation that arise from time to time (here is another one: http://i9606.blogspot.com/2009/02/semantic-dissonance-in-uniprot.html) Thanks! Take care, Fred
