Definition

A tango.info object id is a tango.info object name that identifies exactly one tango.info object.

Descriptive information

Currently the ":" is used only in the time component[1] of an ISO 8601 identifier.

Currently the "/" is used only in

Currently the "_" is used only in the youtube videoID.

Currently the "." is used only in the

  • tango.info youtube video id, format: youtube.<youtube video id>
  • tango.info ipi person id, format: ipi.<IPI-13 number>

Currently case sensitivity only exists in
