Identifier

Full Title or Meme

An identifier is basically a name that is assigned to a digital Entity or even to a single digital interchange (like a Session ID or cookie).

Context

In this wiki all Identifiers apply only to digital entities which includes data base entries, like User Objects. Real-world names are considered to be merely Attributes.

Problems

• There is a very real confusion in the real-world as to the meaning of terms used in Identity Management.
• Lots of the energy spent by philosophers revolves around verbalism, or arguing about the meaning of words.
• The page on Knowledge discusses these problems in more detail.

Solutions

This wiki seeks to have a common understanding. So terms are given more precise meaning in order that the statements made here can be more logically precise.
