+
+=====================
+ type:tempest-plugin
+=====================
+
+This tag is part of the type-classification system for projects
+managed by the release team. ``type:tempest-plugin`` indicates that a
+deliverable is meant to be consumed by :ref:`project-tempest` as a
+plug-in, to provide an unified integration test suite for a given project.
+
+
+Application to current projects
+===============================
+
+.. tagged-projects:: type:tempest-plugin
+
+
+Rationale
+=========
+
+We have a growing number of projects that are Tempest plugins, and it would be
+useful to have them easily grouped together. Using this tag will help both users
+and automated tooling identify which deliverables provide companion
+functionality for Tempest.
+
+
+Requirements
+============
+
+* The repository contains code meant to be dynamically loaded by
+  Tempest to provide an unified integration test suite for a given project.
+
+
+Tag application process
+=======================
+
+Anyone may propose adding or removing this tag to a set of projects by
+proposing a change to the openstack/governance repository. The change
+is reviewed by the Release Team and the QA PTL, and the Technical
+Committee finally approves it using its lazy consensus approval rule.
+
+
+Deprecation
+===========
+
+There is no deprecation process for tags in the ``type`` namespace. If
+we need to change the type of a project, we can just do that.
