Information coding

The mission of the Media Working Group is to develop and improve client-side media processing and playback features on the Web.
 
Standardization efforts to develop media foundations for the Web, such as the HTMLMediaElement interface and Media Source Extensions, have helped turn the Web into a major platform for media streaming and media consumption. Building on the experience gained through implementation, deployment and usage of these technologies, and on incubation discussions within the Web Platform Incubator Community Group, the Media Working Group will extend media foundations with new standardized technologies to improve the overall media playback experience on the Web.
 
The scope of the Media Working Group is:

• Detection of media capabilities
• Detection of the autoplay policy
• Statistics on perceived playback quality
• Generation of media streams for playback
• Playback of encrypted content
• Exposure of media features at the system level to Web applications (e.g. access to platform media keys, display of media metadata at the system level, creation of an always-on-top video window) to Web applications
• Exposure of metadata event tracks synchronized to audio or video media

The TOSCA Simple Profile in YAML specifies a rendering of TOSCA which aims to provide a more accessible syntax aswell as a more concise and incremental expressiveness of the TOSCA DSL in order to minimize the learning curve and speed the adoption of the use of TOSCA to portably describe cloud applications. This proposal describes a YAML rendering for TOSCA. YAML is a human friendly data serialization standard (http://yaml.org/) with a syntax much easier to read and edit than XML. As there are a number of DSLs encoded in YAML, a YAML encoding of the TOSCA DSL makes TOSCA more accessible by these communities.This proposal prescribes an isomorphic rendering in YAML of a subset of the TOSCA v1.0 XML specification ensuring that TOSCA semantics are preserved and can be transformed from XML to YAML or from YAML to XML. Additionally, in order to streamline the expression of TOSCA semantics, the YAML rendering is sought to be more concise and compact through the use of the YAML syntax.

This specification defines a profile for the use of the OASIS eXtensible Access Control Markup Language (XACML), versions 3.0 [XACMLv3]and earlier. Use of this profile requires no changes or extensions to the XACMLstandard. This specification assumes the reader is somewhat familiar with XACML. XACML can be used for controlling access within a single application.This removes hard-coded security constraints from the application code, making it easier to change them. It also makes it possible to use a standard Policy Decision Point (PDP), so that organizations can make a proper make-or-buy decision. For virtually all organizations, authorization is not their core business, so being able to use an off-the-shelf product is appealing. Although these are substantial benefits, XACML really shines when authorizationis completely externalized from the application. Policies can then be reused across many applications, each using the same PDP. This leads to greater consistency of access control rules and improved efficiency in maintaining them.

While industry-specific data formats have the advantage of maximal optimization for their busines scontext, the existence of different formats to accomplish the same purpose in different business domainsis attended by a number of significant disadvantages as well.  The OASIS Universal Business Language (UBL) is intended to help solve these problems by defininga generic XML interchange format for business documents that can be restricted or extended to meet the requirements of particular industries.

Cloud computing is a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand. The cloud computing paradigm is composed of key characteristics, cloud computing roles and activities, cloud capabilities types and cloud service categories, cloud deployment models and cloud computing cross cutting aspects.

This Recommendation | International Standard provides an overview of cloud computing, and defines related terms.
The terms and definitions provided in this Recommendation | International Standard:
– cover commonly used terms and definitions in cloud computing standards;
– will not cover all terms and definitions used in cloud computing standards; and
– do not preclude the definition of additional terms for use in cloud computing standards.

Cloud computing is a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on demand. See Rec. ITU-T Y.3500 | ISO/IEC 17788.  The CCRA presented in this Recommendation | International Standard provides an architectural framework that is effective for describing the cloud computing roles, sub-roles, cloud computing activities, cross-cutting aspects, as well as the functional architecture and functional components of cloud computing.

Recommendation ITU-T Y.3510 provides requirements for cloud computing infrastructure; these include the essential capabilities for processing, storage and networking resources, as well as the capabilities of resource abstraction and control.

Recommendation ITU-T Y.3511 describes the framework for interactions of multiple cloud service providers (CSPs), which is referred to as inter-cloud computing. Based on several use case, and after considering the different types of service offerings, this Recommendation describes the possible relationships (peering, federation or intermediary) among multiple CSPs. By introducing the concept of primary CSP and secondary CSP, the Recommendation further describes CSP interactions for the cases of federation and intermediary patterns. Finally, relevant functional requirements are derived.

Recommendation ITU-T Y.3516 specifies inter-cloud computing functional architecture, including functions and functional components, based on the inter-cloud computing framework specified in [ITU-T Y.3511]. The Recommendation builds upon the functional view of the cloud computing reference architecture [ITU-T Y.3502] and makes extensions to functional components with inter-cloud functions. This Recommendation also describes the mapping between functions and functional requirements of inter-cloud computing and examples of inter-cloud related reference points.

Standardization of graphic character sets and their characteristics, including string ordering, associated control functions, their coded representation for information interchange and code extension techniques. Excluded: audio and picture coding.

SC 2 experts have been working hard to develop Universal Coded Character Set, ISO/IEC 10646, and related standards which are the fundamental basis of Information systems and being referred from every standard involving character-based information exchange and/or processing.

The first version of ISO/IEC 10646 standardized 32,884 characters and published in 1993. Edition 5 of it, the latest version currently under development, will cover over 130,000 characters.

SC2 will keep the quality and speed of its work to develop standards for a character. And close cooperation between SC2 and other all committees to develop standards involving character codes is essential.
