ISO 16757-2:2016 describes the modelling of building services product geometry. The description is optimized for the interchange of product catalogue data and includes(a) shapes for representing the product itself,(b) symbolic shapes for the visualization of the product's function in schematic diagrams,(c) spaces for functional requirements,(d) surfaces for visualization, and(e) ports to represent connectivity between different objects.The shape and space geometry is expressed as Constructive Solid Geometry (CSG) based on geometric primitives concatenated to boundary representations by Boolean operations. ISO 16757-2:2016 uses the applicable primitives from ISO 10303‑42 and from ISO 16739 and adds primitives which are required for the special geometry of building services products. For symbolic shapes, line elements are also used. ISO 16757-2:2016 neither describes the inner structure and internal functionality of the product nor the manufacturing information because this is typically not published within a product catalogue. Building services products can have millions of variant dimensions. To avoid the exchange of millions of geometries, a parametric model is introduced which allows the derivation of variant-specific geometries from the generic model. This is necessary to reduce the data to be exchanged in a catalogue to a manageable size. The parametric model will result in smaller data files, which can be easier transmitted during data exchanges. The geometry model used does not contain any drawing information such as views, line styles or hatching.

This document describes the COLLADA schema. COLLADA is a Collaborative Design Activity that defines an XML-based schema to enable 3D authoring applications to freely exchange digital assets without loss of information, enabling multiple software packages to be combined into extremely powerful tool chains. The purpose of this document is to provide a specification for the COLLADA schema in sufficient detail to enable software developers to create tools to process COLLADA resources. In particular, it is relevant to those who import to or export from digital content creation (DCC) applications, 3D interactive applications and tool chains, prototyping tools, real-time visualization applications such as those used in the video game and movie industries, and CAD tools. This document covers the initial design and specifications of the COLLADA schema, as well as a minimal set of requirements for COLLADA exporters. This document covers the following information:(a) initial design and specifications of the COLLADA schema;(b) requirements of COLLADA tools and a minimal set of requirements for COLLADA exporters;(c) detailed explanations for COLLADA programming;(d) core elements that describe geometry, animation, skinning, assets, and scenes;(e) physics model, visual effects (FX), boundary representation (B-rep) of animation, kinematics.The document does not specify the implementation of, or definition of a run-time architecture for viewing or processing of COLLADA data.

This part of ISO 10303 specifies the use of the integrated resources necessary for the scope and information requirements for the exchange of building element shape, property, and spatial configuration information between application systems with explicit shape representations. Building elements are those physical things of which a building is composed, such as structural elements, enclosing and separating elements, service elements, fixtures and equipment, and spaces. Building element shape, property, and spatial configuration information requirements can be used at all stages of the life cycle of a building, including the design process, construction, and maintenance. Building element shape, property, and spatial configuration information requirements specified in this part of ISO 10303 support the following activities:(a) concurrent design processes or building design iterations;(b) integration of building structure designs with building systems designs to enable design analysis;(c) building design visualization;(d) specifications for construction and maintenance;(e) analysis and review.The following are within the scope of this part of ISO 10303:(1) explicit representation of the three-dimensional shape of building elements using boundary representation (B-rep) solid models, swept solid models, or constructive solid geometry (CSG) models.(2) the spatial configuration of building elements that comprise the assembled building;(3) building structures that represent physically distinct buildings that are part of a single building complex;(4) non-structural elements that enclose a building or separate areas within a building;(5) the shape and arrangement of equipment and service elements that provide services to a building;(6) the shape and arrangement of fixtures in a building;(7) specification of spaces and levels;(8) the shape of the site on which the building will be erected;(9) specification of properties of building elements, including material composition;(10) specification of classification information;(11) association of properties and classification information to building elements;(12) changes to building element shape, property, and spatial configuration information;(13) association of approvals with building element shape, property, and spatial configuration information; and(14) as-built record of the building.

ISO 10303-46 specifies the integrated resource constructs for Visual presentation. ISO 10303-46 specifies the integrated resources for the visualization of displayable product information. Presentation data as described in ISO 10303-46 are combined with product data and are exchanged together between systems with the aim that the receiving system can construct one or several pictures of the product information suitable for human perception. Product information can be visualized in two ways: either by realistic, life-like images according to the rules of projective geometry and light propagation and reflection, or by symbolic presentations that conform with draughting standards and conventions. ISO 10303-46 supports both types of presentations. The two types of visualization processes require different kinds of graphical transformations and these can be combined in the same picture. The actual generation of the picture from the product information and its presentation data is left to the receiving system. The rendered depiction can deviate from an ideal target because of limitations in the capabilities of graphics systems.

This document gives the scientific summaries of visually induced motion sickness resulting from images presented visually on or by electronic display devices. Electronic displays include flat panel displays, electronic projections on a flat screen, and head-mounted displays. Different aspects of human-system interaction are covered in other parts of the ISO 9241 series (see Annex A).

This includes - requirements - guidance on how to identify points of interoperability - guidance on how to express behavioral and policy information on capabilities - guidance on how to achieve trustworthiness interoperability, and - use cases and examples.

ISO/IEC 21823-3:2021 provides the basic concepts for IoT systems semantic interoperability, as described in the facet model of ISO/IEC 21823-1, including:(1) requirements of the core ontologies for semantic interoperability;(2) best practices and guidance on how to use ontologies and to develop domain-specific applications, including the need to allow for extensibility and connection to external ontologies;(3) cross-domain specification and formalization of ontologies to provide harmonized utilization of existing ontologies;(4) relevant IoT ontologies along with comparative study of the characteristics and approaches in terms of modularity, extensibility, reusability, scalability, interoperability with upper ontologies, and so on; and(5) use cases and service scenarios that exhibit necessities and requirements of semantic interoperability.

This document investigates barriers and proposes measures to improve interoperability between geospatial and BIM domains, namely, to align GIS standards developed by ISO/TC 211 and BIM standards developed by ISO/TC 59/SC 13. Where relevant this document takes into account work and documents from other organizations and committees, such as buildingSMART, International (bSI), Open Geospatial Consortium (OGC) and Comité Européen de Normalisation (CEN). The focus is to identify future topics for standardization and possible revision needs of existing standards. This document investigates conceptual and technological barriers between GIS and BIM domains at the data, service and process levels, as defined by ISO 11354 (all parts).

Advice is given for cloud computing ecosystem participants (cloud vendors, service providers, and users) of standards-based choices in areas such as application interfaces, portability interfaces, management interfaces, interoperability interfaces, file formats, and operation conventions. These choices are grouped into multiple logical profiles, which are organized to address different cloud roles.

A functional model for federation based on the NIST Cloud Federation Reference Architecture is defined in this standard. This model allows a range of deployment topologies and governance. As a general federation model, it can be applied to many application domains using different implementation approaches. As such, it includes cloud-to-cloud federation and interoperability.

This standard provides a general shared function model for cloud computing, in order to normalize how functions are shared between cloud service providers (CSPs) and cloud service customers (CSCs). The standard specifies functions ownership from seven aspects for three main cloud service delivery models, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). The seven aspects of function are as follows:1) The physical infrastructure function.2) The virtualization infrastructure function.3) The operating system function.4) The network control function.5) The application function.6) The data function.7) The identity and access management function. Each of the seven aspects considers many factors including security, management, etc. In this standard, levels 1 to 4, which are clearly the service provider's function for IaaS, PaaS, and SaaS, are briefly mentioned for the integrity of the model. This standard focuses on levels 5, 6, and 7.

The standard specifies how Augmented Reality and Virtual Reality (AR/VR) devices should be set up and used in the enterprise; in a manner that ensures Health and Safety (H&S) is maintained, H&S consequences are understood, and additional risks are not introduced. Within this concept of safe usage, there is particular focus on guidance around safe immersion (time) and safety in the workplace. This ISO/IEC standard:(a) defines the concepts of AR, VR, the virtuality continuum and other associated terms such as Augmented Virtuality and Mixed Reality;(b) provides guidance on setting up AR systems;(c) provides guidance on setting up VR systems;(d) provides guidance on safe usage and immersion in AR systems both in the consumer and enterprise domains; and(e) provides guidance on safe usage and immersion in VR systems both in the consumer and enterprise domains.This standard focuses on visual aspects of AR and VR. Other modes such as haptics and olfactory are not addressed within this standard. The standard covers both the hardware (the physical VR/AR head mounted displays) and areas of visual stimulus (the environments and graphics displayed in those headsets). The standard does not cover all possible visual stimulus scenarios; focus is directed toward those areas that are known to have implications on safe use. This specifically includes the source vection (visual illusion of self-motion in physically stationary VR/AR users) and/or motion (physical movement of VR/AR users) and associated safe use considerations. It should be noted that AR/VR have some shared safety concerns, but many are distinct to AR or VR and a consumer or enterprise environment. As such all of these are in scope, and the standard is structured to account for these differences.
