Definition:
|
An abbreviation, pronounced "esh", for the concept of a web link (a URL string beginning https:// or http://). When prepended to an alphanumeric string beginning with a capital letter, possibly followed by a URL path, the whole string represents a hypothetical URL with a variable server name. When prepended to a well-formed internet domain name, possibly followed by a URL path, the whole string represents a URL beginning either https or http. When prepended to a URL path beginning "/", the whole string represents a URL with domain name unspecified. The plural form is πes. As a verb, it means to transform an identifier into an actionable π.

When actionability is unimportant, π/foo is a compact way to write and pronounce https://www.example.org/foo. Distinct web servers πA and πB represent two web namespaces. Legacy, pre-Internet identifiers can often be πed by adding suitable prefix strings, promoting them to actionable, globally unique identifiers. The π symbol is suggested by drawing the individual letters of "HTTPS" on top of each other (superimposing them).
