Content Assembly Mechanism (CAM)〔Standard defined in http://docs.oasis-open.org/cam/〕 is an XML-based standard for creating and managing information exchanges that are interoperable and deterministic descriptions of machine-processable information content flows into and out of XML structures. CAM is a product of the OASIS Content Assembly Technical Committee. The CAM approach aligns with the National Information Exchange Model (NIEM) approach and assists with producing Information Exchange Package Documentation (IEPD). The camprocessor tools enable creation of realistic XML examples from XSD schema structure definitions. These XML samples simulate test cases for use in interoperability testing and determination of templates for use in actual business information exchanges. The single most important problem that CAM is solving is simpler and more reliable interoperability for business information exchanges. Today's electronic commerce via the internet is extremely limited in the amount of automation or integration that is occurring. The ability to share accurate concise and verifiable information exchange definitions is a critical next step in enabling easier and cheaper global commerce. CAM is emerging as the definitive standard underlying effective management of information exchanges through the critical mass being generated by the open source solution. A broad range of OASIS standard definitions are now being documented, validated and enhanced using the CAM open source toolset and approach. To date these include EDXL, CIQ, and EML. CAM use is also extending to external industry groups such as PESC, MISMO, STAR Automotive, CAQH and then for government uses including stratML, LEXS and NIEM. Each group faces the same challenges in promoting localizations of their overall standards in ways that can be quickly verified and adopted. Using CAM they are able to take their existing XSD schema work and rapidly develop localization templates, XML test cases, new subset schemas for use with web services and create re-usable want lists and content hints. In addition CAM templates are used to build domain dictionaries directly from the XSD schema definitions and then produce cross-reference spreadsheets for individual templates to the master dictionary definitions. All these capabilities are aimed at improving the quality and speed of implementation and interoperability using business information exchanges based on XML. == History of CAM == The OASIS Content Assembly Technical Committee (CAM TC), which met for the first time in January 2003, was chartered "to produce a specification of a generalized mechanism in XML whereby implementers can deliver the means to bring together business process context and the localized implementation business rules needed to take a raw industry standard schema instance and combine that with actual business information content, context and roles and produce a valid consistent XML document instance." () OASIS is developing specifications for business process mechanisms, industry standard schemas, registry systems, and schema mechanisms. The CAM specification will allow these four components to be brought together in a consistent and standard way and publish assembly implementation instructions based on these OASIS specifications. This will facilitate the work of industry groups and allow development of software tools that work consistently with all these specifications. The original work predating CAM was begun in the later days of the ebXML initiative as an offshoot of the ebXML Registry work. This working group was dubbed "BRIM" – Business Registry Interface Model and the focus was Registry content assembly services and content syntax storage specifications (link to BRIM reference at CEFACT ). In addition the BRIM work was also positioned to enable core component message assembly (CCMA) for business processes. The work was moved into OASIS at the end of 2002 to better facilitate the necessary XML development. Implementations and deployments of CAM V1.1 are in progress as of this writing (January-2009) including open source solutions using Java and XSLT. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Content Assembly Mechanism」の詳細全文を読む スポンサード リンク
