The present document provides reference test material and test results for improved usability of technologies in TS 26.118: Virtual Reality (VR) profiles for streaming applications.

The specification TS 26.118 includes several VR media profiles for video and a single media profile for audio with different configuration options. The specification focuses primarily on interoperability requirements for VR360 applications, but does not address performance characterization of the solutions. In order for content providers and the rest of the ecosystem to be able to select and configure the technologies defined in TS 26.118 and to generate content for streaming applications, collecting such information would be most valuable.

This standard specifies the requirements and test methods for the motion to photon (MTP) latency that causes virtual reality (VR) sickness while users are using the virtual reality content. This standard is applicable to VR content related with software, hardware, and human factors regarding MTP latency.

This document is the first of a family of standards. This document specifies the behaviour of Web APIs that provide access to features in a dataset in a manner independent of the underlying data store. This document defines discovery and query operations. Discovery operations enable clients to interrogate the API, including the API definition and metadata about the feature collections provided by the API, to determine the capabilities of the API and retrieve information about available distributions of the dataset. Query operations enable clients to retrieve features from the underlying data store based upon simple selection criteria, defined by the client.

This document defines the conceptual framework and mechanisms for mapping information elements from Building Information Modelling (BIM) to Geographic Information Systems (GIS) to access the required information based on specific user requirements. The conceptual framework for mapping BIM information to GIS is defined with the following three mapping mechanisms: (1) BIM to GIS Perspective Definition (B2G PD); (2) BIM to GIS Element Mapping (B2G EM); (3) BIM to GIS LOD Mapping (B2G LM). This document does not describe physical schema integration or mapping between BIM and GIS models because the physical schema integration or mapping between two heterogeneous models is very complex and can cause a variety of ambiguity problems. Developing a unified information model between BIM and GIS is a desirable goal, but it is out of the scope of this document. The scope of this document includes the following:

(1) definition for BIM to GIS conceptual mapping requirement description;

(2) definition of BIM to GIS conceptual mapping framework and component; and

(3) definition of mapping for export from one schema into another.

The following concepts are outside the scope:

(1) definition of any particular mapping application requirement and mechanism;

(2) bi-directional mapping method between BIM and GIS;

(3) definition of physical schema mapping between BIM and GIS; and

(4) definition of coordinate system mapping between BIM and GIS.

NOTE: For cases involving requirements related to Geo-referencing for providing the position and orientation of the BIM model based on GIS, there exist other standards such as ISO 19111 and the Information Delivery Manual (IDM) from buildingSMART on Geo-referencing BIM.

Defines:

- common formats,

- values, and

- coding for Internet of things (IoT).

This document specifies technical aspects related to the extraction, decoupling, trading, and benefits of data components throughout the digital twin life cycle.

Definition of DTw correspondence measure; Components of the measure such as similarity, resolution, latency, LoD (level of detail); Quantification of the measure, Relation with other DTw projects including maturity level; and Unique features of DTw including twinning.

This standard defines a digital twin maturity model for industry, including digital twin capability domains and corresponding subdomains. This standard also defines assessment methodologies, including assessment content, assessment processes, and assessment maturity levels.

This document establishes terminology for Digital Twin (DT) and describes concepts in the field of Digital Twin, including the terms and definitions of Digital Twin, concepts of Digital Twin (e.g., Digital Twin ecosystem, lifecycle process for Digital Twin, and classifications of Digital Twin), Functional view of Digital Twin and Digital Twin stakeholders. This document can be used in the development of other standards and in support of communications among diverse, interested parties/stakeholders. This document is applicable to all types of organizations (e.g., commercial enterprises, government agencies, not-for-profit organizations).
