1、 GEIA STANDARD EIA-836A Configuration Management Data Exchange and Interoperability EIA-836A March 2007 GOVERNMENT ELECTRONICS AND INFORMATION TECHNOLOGY ASSOCIATION A Sector of the Electronic Industries Alliance Copyright Government Electronics Version 1.2 has the changes accepted. Unlike Version 1
2、0, where the Business Objects were located within the reference schema, the Business Objects in the interim versions 1.1 and 1.2 consist of individual schemas that relate to a Program or Project, a Product or an Instance of a Product. The elements used in the Business Objects are defined in the Ref
3、erence Schema, whis is linked to and accessible from each of the business objects. An XML schema language conversion of the Reference Schema DTD is included and is an exact equivalent. Jan 2004 A This revision provides significant technical changes: the data model was restructured using a discipline

This standard is written generically tocover all products, but this revision
10、primarily covers hardware and software. Information for firmware and systemsare included in the hardware area. Facilities are addressed, but only in the most basic way and only in support ofhardware and software for operational purposes. It is expected that future revisions of this standard will exp

It also includes the requirements forand results of testing, qualification, and certification, and information ne
13、cessary for the operation, maintenance,modification, and disposal of hardware instances. The hardware design provides for the identification of embeddedsoftware. It provides the current design information for the developer, acquirer, and user. It is the baseline for productionand procurement, and th
14、e basis for all proposed design changes.A Hardware instance is called a HardwareUnit . The HardwareUnit is uniquely identified to differentiate it fromall other like pieces of that product. The information captured about the HardwareUnit begins with the “as-built”configuration describing the actual
15、configuration as manufactured, into what higher assembly it was placed, and changesthat were authorized to the design as it was being built. Information captured about the HardwareUnit and changesto its configuration continues throughout its lifecycle, including maintenance, modifications, and dispo
