PD IEC/TR 61908 is applicable to the technology roadmap for industry data dictionary structure, utilization, and implementation.
PD IEC/TR 61908 covers one aspect of industry relationships the data dictionary. A data dictionary is made up of information about products. The products can be electronic components, base material, clothing, chemicals or any product that can be described in terms of an industry understood descriptive name (element) and the characteristics that make up that part (attributes). Another item that helps data dictionaries become very efficient is to reuse the characteristics (attributes) in more than one element. Reuse of information is desirable in any implementation strategy in order to reduce search time for the implementation software. The topic of discussion, therefore, in this report is the status, completeness, implementer goals, and standardization efforts related to electric components.
PD IEC/TR 61908 on the technology roadmap for industry data dictionary is useful for:
A library is like a catalogue. It uses dictionary entries to be built into the database. In a library
you find the characteristics with their values, so you can compare components of different
manufacturers on their characteristics.
PD IEC/TR 61908 defines physical performance requirements or conformance details, the contractual agreements between members of the supply chain handle these according to an implemented revision level to explore the differences and the similarities between their respective approaches to data element dictionaries.
PD IEC/TR 61908 defines the difference between a dictionary and a library to assist you in making informed judgments and continuing to outsource much of the supply chain operations, whether purchasing, fabrication, assembly, or testing of electronic hardware.
