RAIN URI Identifier

Version 2025-12-15 15 December 2025

Active

The RAIN URI Identifier defines how a RAIN item identifier is expressed as a URI, so that it can be read and resolved by a smartphone operating system without a dedicated application. It covers two modes: the URI as the unique item identifier in MB01, optionally extended into user memory, and the URI as an add-on to an existing identifier stored in user memory. Annex B defines the RAIN URI Templates that the RUTlist publishes.

Always the current edition. This address does not change when a new version is published, so it is the one to give to software.

Always this edition, under the name it was issued with. Cite this where the exact text matters, and it will go on serving these words after a newer version exists.
