The following ITU-T Recommendations and other references contain provisions which, through reference in
this text, constitute provisions of this Recommendation. At the time of publication, editions indicated were
valid. All Recommendations and other references are subject to revision; users of this Recommendation are

3 Definitions

3.1 Terms defined elsewhere

This Recommendation uses the following terms defined elsewhere:
3.1.1 future network (FN) [ITU-T Y.3001]: A network able to provide services, capabilities, and facilities
difficult to provide using existing network technologies. A Future Network is either:
a) a new component network or an enhanced version of an existing one, or
b) a heterogeneous collection of new component networks or of new and existing component
networks that is operated as a single network.
3.1.2 identifier [b-ITU-T Y.2091]: An identifier is a series of digits, characters and symbols or any other
form of data used to identify subscriber(s), user(s), network element(s), function(s), network entity(ies)
providing services/applications, or other entities (e.g., physical or logical objects).
3.1.3 name [b-ITU-T Y.2091]: A name is the identifier of an entity (e.g., subscriber, network element) that
may be resolved/translated into address.

3.2 Terms defined in this Recommendation
This Recommendation defines the following terms:

3.2.1 data ID: An identifier used to identify a data object. It has a form of a series of digits, characters and
symbols or any of these combinations, which generally do not have any meaning.

3.2.2 data name: A string of alpha-numeric characters that is used to identify the data object. A data
name, which may have variable length, is usually configured in such a way that it would be easier to be read
and remembered by humans.
NOTE – A data object may have both data name and data ID. In this Recommendation, data name and data ID are used
interchangeably.
3.2.3 data object: An individually identifiable unit of information created by individuals, institutions and
technology to benefit audiences in contexts that they value.
