International Standard Identifiers

Project description

The package identifiers provides classes that can be used to create and check identifiers for unique objects or unique classes of objects according to international standards.

Definition from Wikipedia:

"An identifier is a name that identifies (that is, labels the identity of) either a unique object or a unique class of objects, where the "object" or class may be an idea, physical [countable] object (or class thereof), or physical [noncountable] substance (or class thereof). The abbreviation ID often refers to identity, identification (the process of identifying), or an identifier (that is, an instance of identification). An identifier may be a word, number, letter, symbol, or any combination of those."
