40、Software engineering, in collaboration with ITU-T. The identical text is published asITU-T Recommendation X.960.Annex A forms a normative part of this International Standard. Annexes B and C are for information only.Introduction This Recommendation | International Standard prescribes the ODP Type Re

41、pository Function (subclause 14.4 of ITU-T Rec. X.903 | ISO/IEC 10746-3) to support the storage, retrieval and management of type descriptions within an identified framework for type descriptions. ITU-T Rec. X.902 | ISO/IEC 10746-2 provides a general definition of type in subclause 9.7; this definit

42、ion allows the description of types using any predicate. ITU-T Rec. X.903 | ISO/IEC 10746-3 introduces a number of target concepts specific to particular viewpoints. This Recommendation | International Standard supports the establishment of type definitions based on the concepts defined in the ODP f

43、amily of Recommendations | International Standards. This Recommendation | International Standard enables type descriptions for use by the ODP functions outlined in ISO/ IEC 10746-3. Type descriptions can occur in specifications from any viewpoint, e.g. enterprise specification can introduce enterpri

44、se types. This Recommendation | International Standard specifically addresses the needs of the ODP computational and engineering viewpoint types, but is capable of supporting type descriptions coming from other viewpoint languages. This Recommendation | International Standard permits the use of mult

45、iple type description languages. There are a number of widely used and standardized languages for type description, for example CORBA IDL, ASN.1, LOTOS, GDMO and SDL, which fulfil some of the requirements of type descriptions in ODP-RM. This Recommendation | International Standard does not define a

46、single all-encompassing type language. Users can use either existing languages or languages defined within other ODP Recommendations | International Standards. Annex B is an informative annex outlining languages that support large sets of target concepts. This Recommendation | International Standard

47、 supports type systems with a type Type (e.g. pass type as parameters as in the ODP computational language). ITU-T Rec. X.903 | ISO/IEC 10746-3 defines a subtype relationship between computational operational interface signature types. This Recommendation | International Standards supports a wider v

48、ariety of relationships between types, which might include the analysis of behaviour and environment contracts, but the definition of such relationships is not within the scope of this Recommendation | International Standard. Relationships between types can either be asserted or deduced. It is recog

49、nized that not all relationships (including equivalence) can always be automatically deduced. However, automatic deduction should be encouraged whenever applicable. The type repository function supports the allocation of identifiers to types in order to allow the transmission of these “shorthand“ representations across domains (i.e. between objects using different type repositories). The type repository function addresses interworking and federation to support the distribution of the type repository function by clarifyin
