cite-as: A Link Relation to Convey a Preferred URI for Referencing
Abstract
A web resource is routinely referenced by means of the URI with which
it is directly accessed. But cases exist where referencing a
resource by means of a different URI is preferred. This
specification defines a link relation type that can be used to convey
such a preference.

RFC 8574 The "cite-as" Link Relation Type April 2019
1. Introduction
A web resource is routinely referenced (e.g., linked or bookmarked)
by means of the URI with which it is directly accessed. But cases
exist where referencing a resource by means of a different URI is
preferred, for example, because the latter URI is intended to be more
persistent over time. Currently, there is no link relation type to
convey such an alternative referencing preference; this specification
addresses this deficit by introducing a link relation type intended
for that purpose.
2. Terminology
