This clause contains requirements that all OTDs must satisfy.
It shall be possible to unambiguously map between the OTD's implementation data model and the ISO/TS 22745-10 model in both directions.
Identifiers for concepts, terms, definitions, and images shall be as specified in ISO 22745-13.
An OTD shall meet the requirements of the "free encoding" conformance class specified in ISO 8000-110.
An OTD shall provide a dictionary interface for computer application to application communication that supports:
resolving an OTD identifier to its underlying meaning;
searching for OTD concept identifiers whose terminology matches a given pattern.
EXAMPLE Finding the identifiers of all concepts that have a term containing the words "U" and "bolt".
NOTE 1 It is the intention of ISO TC 184/SC 4/WG 12 to add a requirement that the interface conform to ISO/TS 22745-14 in a future edition of this part of ISO 22745, once ISO/TS 22745-14 is published. Implementers of systems based on this part of ISO 22745 are encouraged to use a dictionary interface that is compatible with the current draft of ISO/TS 22745-14.
NOTE 2 It is recommended that an OTD that is a collection of already standardized terminology be maintained according to the procedures specified in ISO 22745-20.
