Pat, I don't think this discussion was meant to apply to the semantic web generally (but primarily to biomedical ontologies - hence the relevance to this interest group mailing list) and as much as I agree with you about the issues associated with requiring opaque identifiers, this discussion is

This entire discussion is simply absurd, if it is supposed to apply to the semantic web generally. OF COURSE people are not going to re-name the RDFS or OWL vocabulary (for example) with 'opaque' names. Programming languages are not going to use opaque identifiers for their reserved vocabularie

Skipping the line of reasoning that leads to these conclusions... I think one of the main point is the role of the 'web'. Whether we are talking about terminologies encoded in OWL/RDF, or about a distributed web-based information space. I bet we could make a test and see the correlation between

Personally, I don't want tooling to "help". I want to be able to look at what would otherwise be a perfectly readable serialization (Manchester OWL, Turtle, etc.) and be able to read and write it without constantly referring to lookups. I've seen this discussion in the software engineering world ma

So.. a long but useful discussion. That will teach me to open my big mouth :) Is this fair as the PRIMARY reasons for this difference in opinions: 1. Having semantic information such as a label in a URI makes it easier to, at a glance, grasp some sort of meaning of a class/predicate and makes SPA

Hi, I think there is some confusion going on on the subject. We need to name things in an unique way. In many cases codes are just the best option. No wonder we all have tax-codes and the like, it's easier than to try to find a unique name based on some attributes. The case of terminologies is a

FYI, the rationale behind the use of identifiers for SNOMED-CT (ironically enough, given this thread) was to allow for some organizational semantics to be embedded in them. See: http://www.ihtsdo.org/fileadmin/user_upload/Docs_01/Publications/SNOMED_CT/SNOMED_CT_Identifiers_v1.0.pdf [[[ The Sct

Other standards (outside of semantic web) saw the need to rely on numeric identifiers, even if that created a burden for their users e.g. in SNOMED Lung = T-28000 Of course it is a pain to query SNOMED with "all the diseases that affect T-28000". But the fact is that despite the inconvenience of h

Here's my thinking: The whole point of the semantic web is to get away from relying on terms. Why would you intentionally want to become dependent upon labels (terms)? Label's are not identifiers; they are annotations. There is no uniqueness guarantee. A concept can have many labels and many co

I think all those who suggested "semantic-less" or "meaning-less" identifiers should come out and define what they mean by "semantics/meaning". Does a URI "http://example.com/foo#good"; carries the semantics of *good* as how the word "good" is defined in an English dictionary? Unless there is a sp

Hi All, Sorry to come in so late to this discussion but It would seem that the meaning that resides in the application (or in a SPARQL query) should be part of the discussion. Even if the data identifiers have really fine readable meanings, an application can change the semantics completely.
