The eOTD is an ISO 22745 compliant dictionary managed by ECCMA, and was developed with the support of the Defense Logistics Information Service (DLIS), an agency of the US Defense Logistics Agency (DLA). ISO 22745 is the international standard for the exchange of characteristic data, which was developed with the aim of bridging the gap between military and commercial cataloging standards.
The eOTD contains terms, definitions and images linked to public domain concept identifiers, which are used to create unambiguous language independent descriptions of individuals, organizations, locations, goods, services, processes, rules and regulations. The process of using concept identifiers from an external open technical dictionary is a form of semantic encoding compliant with the requirements of ISO 8000-110:2009, the international standard for the exchange of quality master data.
The eOTD does not include a class hierarchy or class-property relationships. This is offered in the eDRR (ECCMA Data Requirements Registry).
Using the eOTD to improve data quality
Organizations use the eOTD to create data requirement specifications as identification guides or cataloging templates. These identification guides contain the class-property relationships that are used for cataloging, to measure data quality as well as to create requests for data or requests for data validation.
eOTD public domain concept identifiers are designed specifically to allow the creation of portable data and to protect corporate master data from third party copyright claims. Using public domain identifiers as metadata creates portable data that can be legally separated from the software application that was used to create it.
