I've been noticing that I'm getting more and more behind on the online identity conversations, implementations, ruminations, and exploitations (?). But I try to keep track of what pops up on the weblogs of Mary Hodder and Kaliya Hamlin, for starters.
I was looking at the acronym "ID" and that triggered the following set of associations:
IDs = identifiers, could even be names, but seem to be more formal, as in "Show me your ID."
UIDs = unique ones of these ID thingys. These show up sometimes on software modules.
GUIDs = globally unique ID thingys. I've seen these being applied to globally identifying species, and again to software (where it's sometimes spelled UUID).
and this led me to yet another acronym:
FLUIDs = which I'm defining as familiar, famous, or favorite local, unique, identifier thingys. These, I think, are also known as names.
