Experiences and discussions
- URIs in Data Primer by @JeniT
- Choosing URIs, not a five minute task a blog post with an alternative approach than the UK gov, by Rob Styles, @mmmmmrob, at Talis
- Discussion threads on on W3C HCLS mailing list (public-semweb-lifesci@w3.org June 2011) about URI syntax (language mnemonic vs. alphanumeric). Using an example from the updated OBO Relationship Ontology: part_of (language mnemonic) vs. RO_0000001 (alphanumeric). See two threads: "My task from last week: Semantic free identifiers" and "In defense of meaninglessness: an ontologist's dilemma". Especially @micheldumontier's pragmatic anticipation of language mnemonic AND alphanumeric identifiers.
- A great blog post by @JeniT What does URIs Mean Anyway? summarizing the the different options to either cope with, constrain or avoid using the same URI meaning different things such as: the Wikipedia page about Moby Dick, the novel Moby Dick, the whale, Moby Dick, the story Moby Dick (originally a novel but later adapted as a film), and so on.

Some background reading
- What Is a URI and Why Does It Matter? by Henry S. Thompson at Language Technology Group of HCRC in the School of Informatics at the University of Edinburgh.
- Linked Data Strategy for Global Identity by Hugh Glaser and Harry Halpin
- Rethinking the Meaning of Identifiers in Information Infrastructures describing the significant economic and political issues with more profound consequences in the design, choice, assignment, withdrawal, and replacement of identifiers such as personal identification numbers, student numbers, and license numbers. Interesting insights in the problems associated with the Swedish PID (personal identification) number.
