The work of preparing Inte
5、rnational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison wi
6、th ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technic
7、al committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstanc
8、es, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publica
9、tion if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee castin
10、g a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it
11、 must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/PAS 17506 was prepare
12、d by the Khronos Group (as COLLADA Digital Asset Schema Release 1.5.0 Specification, April 2008) and was adopted by Technical Committee ISO/TC 184, Automation systems and integration, Subcommittee SC 4, Industrial data.

13、ved 1Industrial automation systems and integration COLLADA digital asset schema specification for 3D visualization of industrial data 1 Scope This Publicly Available Specification describes the COLLADA schema. COLLADA is a COLLAborative Design Activity that defines an XML-based schema to enable 3D a
14、uthoring 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 Publicly Available Specification is to provide a specification for the COLLADA schema in sufficient detail
15、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 th
16、ose used in the video game and movie industries, and CAD tools. This Publicly Available Specification covers the initial design and specifications of the COLLADA schema, as well as a minimal set of requirements for COLLADA exporters. 2 Requirements Requirements are indicated using “must” in the foll
17、owing publication (reproduced on the following pages), which is adopted as a Publicly Available Specification: COLLADA Digital Asset Schema Release 1.5.0 Specification, April 2008.
