ETSI in respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the
ETSI IPR online database.
Pursuant to the ETSI Directives including the ETSI IPR Policy, no investigation regarding the essentiality of IPRs,
including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not
referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become,
essential to the present document.

Foreword
This Group Specification (GS) has been produced by ETSI Industry Specification Group (ISG) Augmented Reality
Framework (ARF).
The present document is part 6 of a multi-part deliverable covering Interoperability Requirements for AR components,
systems and services, as identified below:
Part 1: "Overview";
Part 2: "World Storage and AR Authoring functions";
Part 3: "World Capture, World Analysis and Scene Management";
Part 4: "World Analysis, World Storage and Scene Management functions";
Part 5: "External Communications";
Part 6: "3D Objects of World for AR Authoring and Scene Management functions".
The ISG ARF shares the following understanding for Augmented Reality: Augmented Reality (AR) is the ability to mix
in real-time spatially-registered digital content with the real world. The present document specifies interoperability
requirements for References Points AR15 and AR19 of the reference architecture for AR solutions defined in ETSI
GS ARF 003 [1].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document specifies the high level Reference Point requirements between the AR Authoring functions,
Scene Management and World Storage as they are identified in ETSI GS ARF 003 [1]. It further defines the
requirements of Reference Points "3D objects of World ARA" (AR15) and "3D Objects of World SM" (AR19).
