ETSI

The purpose of this Group Report is to explain with examples the usage of NGSI-LD information model and API, as defined in GS-004 prelimAPI, and considering also some use cases from GR-002 for ICT professionals. Worked examples are provided, with code fragments made available in a public repository. No changes in the GS-004 prelimAPI specification can be introduced or proposed in this document.

This Group Specification provides additions and corrections to the GS-009 NGSI-LD API specification, based on feedback received from developers in the linked-data, internet-of-things, mobile-apps and smart-applications communities, as well as from end users and stakeholders.

Defining indicators (KPIs) for Smart Cities expressing city level in terms of People, Planet, Prosperity and Governance.,

This extension has been created by investigating resources from potential stakeholders of the ontology, such as standardization bodies (e.g. Open Geospatial Consortium), associations (e.g. Spanish Federation of Municipalities and Provinces), IoT platforms (e.g. FIWARE) and European projects and initiatives (e.g. ISA2 programme, as reported in ETSI TR 103 506)

The report will identify the role of existing standards relevant to augmented reality and document any interoperability gaps. This activity will analyse the standardization work done around augmented reality in various standards setting organizations.

The present document collects information on eXtended Reality (XR) in the context of 5G radio and network services. The primary scope of the present document is the documentation of the following aspects:- introducing Extended Reality by providing definitions, core technology enablers, a summary of devices and form factors, as well as ongoing related work in 3GPP and elsewhere,- collecting and documenting core use cases in the context of Extended Reality,- identifying relevant client and network architectures, APIs and media processing functions that support XR use cases,- analysing and identifying the media formats (including audio and video), metadata, accessibility features, interfaces and delivery procedures between client and network required to offer such an experience,- collecting key performance indicators and Quality-of-Experience metrics for relevant XR services and the applied technology components, and- drawing conclusions on the potential needs for standardisation in 3GPP.

The present document presents and classifies industrial use cases for AR applications and services. It forms the basis for the requirements document to be drafted ETSI GS ARF 004: Augmented Reality Framework (ARF) Interoperability Requirements for AR components, systems and services.

The present document specifies a functional reference architecture for AR components, systems and services. The structure of this architecture and the functionalities of its components have been derived from a collection of use cases, ETSI GR ARF 002 (V1.1.1): Augmented Reality Framework (ARF) Industrial use cases for AR applications and services, and an overview of the current landscape of AR standards, ETSI GR ARF 001 (V1.1.1): Augmented Reality Framework (ARF); AR standards landscape. The present document introduces the characteristics of an AR system and describes the functional building blocks of the AR reference architecture and their mutual relationships. The generic nature of the architecture is validated by mapping the workflow of several use cases to the components of this framework architecture.

The present document reviews the high level Reference Point requirements between the Scene Management and External Application Support functions as they are described in ETSI GS ARF 003 (V1.1.1): Augmented Reality Framework (ARF) AR framework architecture.

The present document provides an overview and an introduction to the interface specification for the reference points "AR 16 - World Anchors" and "AR 17 - Reference Objects" of the AR framework architecture, ETSI GS ARF 003 (V1.1.1): Augmented Reality Framework (ARF) AR framework architecture, developed by the ETSI Industry Specification Group (ISG) for an Augmented Reality Framework (ARF). The actual interface specification is provided as OpenAPI™ specification, ARF005 - World Storage API, revision 1.0.0, and forms the baseline for the present document.

The present document collects information on glass-type AR/MR devices in the context of 5G radio and network services. The primary scope of this Technical Report is the documentation of the following aspects:- providing formal definitions for the functional structures of AR glasses, including their capabilities and constraints,- documenting core use cases for AR services over 5G and defining relevant processing functions and reference architectures,- identifying media exchange formats and profiles relevant to the core use cases,- identifying necessary content delivery transport protocols and capability exchange mechanisms, as well as suitable 5G system functionalities (including device, edge, and network) and required QoS (including radio access and core network technologies),- identifying key performance indicators and quality of experience factors,- identifying relevant radio and system parameters (required bitrates, latencies, loss rates, range, etc.) to support the identified AR use cases and the required QoE, and- providing a detailed overall power analysis for media AR related processing and communication.
