ISO 16684-1:2012(E) BS ISO 16684-1:2012iv Foreword ISO (the International Organization for Standardization) is a worldwide federatio
28、n of national standards bodies (ISO member bodies). The work of preparing International 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.
29、 International organizations, governmental and non-governmental, in liaison with 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 wi
30、th the rules given in the ISO/IEC Directives, Part 2. The main task of technical 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 appro
31、val by at least 75 % of the member bodies casting a vote. ISO 16684-1 was prepared by Adobe (as XMP S pecification Part 1, Data Model Serialization, and Core Properties, July 2010) and was adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 130, Graphic technology, in para
32、llel with its approval by the ISO member bodies. ISO 16684 consists of the following parts, under the general title Graphic technology Extensible metadata platform (XMP) specification: Part 1: Data model, serialization and core properties Future parts will address formal validation of XMP and XML sy
33、ntax for describing XMP UI elements. ISO 16684-1:2012(E) ISO 2012 All rights reservedBS ISO 16684-1:2012 ISO 2012 - All rights reserved vIntroductionThis International Standard specifies a standard for the definition, creation, and processing of metadata thatcan be applied to a broad range of resour
34、ce types. The Extensible Metadata Platform (XMP) was introducedby Adobe Systems Incorporated in 2001 and has since established itself as a critical technology for improvingbusiness efficiency in many industries. The Adobe Systems XMP Specification Part 1 version of July 2010 isthe basis for this Int
35、ernational Standard. Establishing this International Standard ensures the stability andlongevity of its definitions and encourages broader integration and interoperability of XMP with existingstandards.Metadata is data that describes the characteristics or properties of a resource. It can be disting
36、uished from themain content of a resource. For example, for a word processing document, the content includes the actual textdata and formatting information, while the metadata might include properties such as author, modification date,or copyright status. Some information could be treated as either
37、content or metadata, depending on context. In general, metadatais useful without regard for a resources content. For example, a list of all fonts used in a document could beuseful metadata, while information about the specific font used for a specific paragraph on a page would belogically treated as
38、 content.Metadata allows users and applications to work more effectively with resources. Applications can make use ofmetadata, even if they cannot understand the native format of the resources content. Metadata can greatlyincrease the utility of resources in collaborative production workflows. For e
39、xample, an image file might containmetadata such as its working title, description, and intellectual property rights. Accessing the metadata makesit easier to perform such tasks as searching for images, locating image captions, or determining the copyrightclearance to use an image. File systems have
40、 typically provided metadata such as file modification dates and sizes. Other metadata canbe provided by other applications, or by users. Metadata might or might not be stored as part of the resourcewith which it is associated.This International Standard provides a thorough understanding of the XMP
41、data model. It is useful for anyonewho wishes to use XMP metadata, including both developers and end-users of applications that handlemetadata for resources of any kind.The serialization information is vital for developers of applications that will generate, process, or manage filescontaining XMP me
42、tadata. The serialization information will also interest application developers wishing tounderstand file content. This International Standard also provides additional guidelines for programmers whowill implement XMP metadata processors.The International Organization for Standardization (ISO) draws
43、attention to the fact that it is claimed thatcompliance with this document may involve the use of a patent concerning the creation, processing,modification, and storage of XMP metadata.ISO takes no position concerning the evidence, validity and scope of this patent right. The holder of this patentri
44、ght has assured ISO that he is willing to negotiate licences under reasonable and non-discriminatory termsand conditions with applicants throughout the world. In this respect, the statement of the holder of this patentright is registered with ISO. Information may be obtained from:Adobe Systems Incor

47、 the most fundamental aspect. This is an abstract model that defines theforms of XMP metadata items, essentially the structure of statements that XMP can make about resources. Serialization: The serialization of XMP defines how any instance of the XMP data model can be recordedas XML.In addition, th
48、is part of ISO 16684 defines a collection of core properties, which are XMP metadata itemsthat can be applied across a broad range of file formats and domains of usage.The embedding of XMP packets in specific file formats and domain-specific XMP properties are beyond thescope of this part of ISO 166
