28、vised.iv ISO 2017 All rights reserved ISO 22938:2017(E)IntroductionThis document specifies a consistent interchange format for data contained in electronic content/document management (CDM) systems, including documents, their associated resources, and retrieval index values that are stored in, or ma
29、naged by, these technologies. Such a standard should facilitate the exact interchange of CDM data, i.e. the standard should not require that the data be irreversibly modified or packaged within a format that does not allow the reconstruction of the original data. Therefore, this document avoids choo
30、sing one particular data format and anointing it as the interchange standard for CDM. Rather, this document specifies a common markup format, based on the XML (eXtensible Markup Language), which encapsulates all forms of CDM data. A DTD (document type definition) describes the XML markup used for CD
31、M data transfer. The XML format is a W3C (World Wide Web Consortium) standard, adopted in February 1998. XML is extensible, so that additional CDM formats may be easily specified by appropriately updating the DTD.The purpose of this document is to define standards for information interchange in a wa
32、y that benefits both the consumers and vendors of content/document management systems. Some possible benefits are as follows:a) document information can be exported from one standards compliant CDM system and afterwards imported to another standards compliant CDM system;b) disparate CDM systems with
33、in an enterprise (due to autonomous selection, replacement, or merger/acquisition) will be able to exchange or consolidate CDM information.To this end, the standards are defined with the goal of striking a balance between being either too restrictive or too general. They should be broad enough to en
34、compass all common CDM information types and all common uses of CDM systems, as well as ones that might be expected in the future. On the other hand, the standards should be restrictive enough so that CDM vendors do not have inordinate difficulty complying with the standards. ISO 2017 All rights res

41、ic documents is an application of the XML. XML is an extensible, flexible, platform-independent format, and has been adopted by the W3C as a standard (officially a “recommendation” in W3C terminology).The primary use of this document is to exchange data between diverse document management systems th
42、at do not already have an exchange methodology in place. This document is considered to be the foundational platform from which other XML-based exchange standards are developed, ensuring a common framework throughout the document management industry. The use of the ZIP-based Open Packaging Conventio
43、n (OPC) to group the document interchange format XML, the content it describes, and related resources into a single standardized archive file allows the interchange of documents among CDM systems without the risk of the related parts becoming separated or out of sync.5.2 Use of XML and OPC for conte
44、nt/document management data5.2.1 Overview of OPC structureThe document interchange format for electronic documents utilizes the packaging format described in ISO/IEC 29500-2 (“OPC”). This is a ZIP-based format containing data files (“Parts”) and metadata describing relationships between these parts.
45、5.2.2 Content/document management (CDM) Specific OPC structureA document of the format specified in this document which implements OPC packaging shall be an OPC package, as specified in ISO/IEC 29500-2.

Appropriate to contentThe content types of OPC Parts contained in the package shall be mapped to package data as defined in ISO/IEC 29500-2:2012, 10.1.2, which
48、 includes mapping of the content type of most types of data stored in the package to the data in a Content Types stream with the logical name Content_Type.xml included in the package as specified in ISO/IEC 29500-2:2012, 10.2.6.5.2.3 Content/document management (CDM) Specific relationshipsA document
