Made as simple as possible, but not simpler.
Wikidata uses opaque identifiers for its catalogued information resources. For example, the statement “wd:Q42 wdt:P69 wd:Q691283” may map to the label sequence “‘Douglas Adams’ ‘educated at’ ‘St John’s College’” with a language-locale preference of English-US.
I recently encountered the Archival Resource Key (ARK) identifier scheme and read its latest draft specification.
Imagine a data system modeled as three parts: an interface, a processor, and a repository.
After my last note on identifiers, Leo Talirz pointed me to a great riff1 on Tim Berners-Lee’s classic note2 on “cool URIs”.
