uid

UID

"uid" is an hCard property. The semantics of "uid" are defined in RFC2426 section 3.6.7 as noted in the hCard profile. Note the erratum regarding the UID type subproperty.

See also hCard examples for canonical user profile URLs.

This page also documents an effort to define a microformat for identifiers. This effort came about from two angles:

• the need for a module that hCard and hCalendar could reference for defining the behavior of UID
• the need for marking up freeform identifiers that are found in web content

Per the microformats process

• uid-examples
• uid-formats
• uid-brainstorming
