HIts purpose is to specify an operational structure class suitable for videotex interworking as defined in configuration 1 of CCITT Recommendation F.300 and in Recommendation T.564. 2 H Field of application  HThis Recommendation defines an operational application profile, that is in conformance with DTAM (T.400 Series of Recommendations) and that allows operational structures to be interchanged for the purpose of an international videotex interworking.  HThis operational application profile defines the features of the operational structure that can be interchanged. These features are depending on the document structures as specified in the document application profile (see Recommendation T.504). * 3 H References H Rec. F.300: Videotex service'  H Rec.

" 5 H Characteristics supported by this operational application profile 5.1HOverview  HFor the purpose of videotex interworking operational structures are associated with a videotex document to provide an environment for interactive communication, necessary for a recipient to handle the userw's input data as intended by the originator.  HTherefore the purpose of this section is to specify the functional description of the features supported by this operational application profile. 5.2HRange of operational structures  HFor the purpose of an international videotex interworking four operational structures are specified, one of each representing the "data entry structure", the "application control memory", the "administrative structure" and the "special terminal facilities structure" as defined in Recommenda tion T.564. 5.3HGeneric characteristics HNot used. 5.4HSpecific characteristics  HEach of the operational structures specified in this operational application profile only supports specific features of operational structures. 6 H Definition of the operational application profile 6.1HComplexity level of operational structures HFor further study. 6.2HOperational profile level  HOne operational profile has to be defined for every application using operational structures. HThis operational profile specifies: H Four operational structures are used; H Each of the operational structures only contains specific features. HDetails are for further study. 6.3HSpecification of operational structures  HFour operational structures are specified by this operational application profile. 6.3.1HData entry structure  HThe data entry structure as defined in draft Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present.  HThe DataEntrySE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 11.  HThe subordinates of DataEntrySE are: DataEntryProgramSE, FieldSE, RulesSE, PromptSE, and ResultSE.  HDataEntryProgramSE is mapped to composite operational object. FieldSE, RulesSE, PromptSE and ResultSE are mapped to basic operational objects. HFieldSE, PromptSE and ResultSE may have associated operational elements.  HSubordinate to DataEntryProgramSE is DataEntrySubprogramSE. DataEntrySubprogramSE is mapped to basic operational object.  HFor each of the SEs specified above, constraints are defined on the number of SEs which may exist at one time. These constraints are defined in Recommendation T.564. ( 6.3.2HApplication control memory structure  HThe application control memory structure as defined in Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present.  HThe ApplicationControlMemorySE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 12.  HSubordinate to the ApplicationControlMemorySE is the RecordSE. The RecordSE is mapped to basic operational object.  HFor each of the SEs specified above, constraints are defined on the number of SEs which may exist at one time. These constraints are defined in Recommendation T.564. 6.3.3HThe administrative structure  HThe administrative structure as defined in Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present.  HThe AdministrativeInformationSE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 13. 6.3.4HSpecial terminal facilities structure  HThe special terminal facilities structure as defined in Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present.  HThe SpecificTerminalFacilitiesSE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 14.  HSubordinate to the SpecialTerminalFacilitiesSE is the RedefinitionEntitySE. Redefinition EntitySE is mapped to basic operational object.  HFor each of the SEs specified above, constraints are defined on the number of SEs which may exist at one time. These constraints are defined in Recommendation T.564. 6.4HSpecification of attributes  HThe attributes applicable to constituents of the operational structure are defined in the following tables, using the following notation: H  attribute not applicable Hm attribute is mandatory Hnm  attribute is nonmandatory Hd attribute is defaultable  HFrom the attributes specified for operational structures in Annex A to this Recommendation, videotex interworking will not use the attributes operational object class and subordinates. HThe use of the attribute document fragment is for further study. 6.4.1HAttributes of the data entry structure  HTable 1/T.541 shows the use of attributes defined for objects of operational structures. * $TABLE 1/T.541   x|@ w      Attributes  DataEntrySE          DataEntryProgramSE            DataEntrySubprogramSE              FieldSE                RulesSE                  PromptSE                    ResultSE               Object type  m  m  m  m  m  m  m              Object identifier  m  m  m  m  m  m  m    (Note)                     Reference attribute   d  d     nm              Application defined           attribute lists  d  d  d  d  d  d  d              Default value lists  nm                       HP ,x--h.Xp   XXNoteThis attribute may be omitted when the value can be unambiguously derived from the transmission sequence of the relevant objects.'X    XValues for the attribute objecttype XDataEntrySE: 0 XDataEntryProgramSE: 1 XDataEntrySubprogramSE: 2 XFieldSE: 3 XRulesSE: 4 XPromptSE: 5 XResultSE: 6   XTable 2/T.541 shows the use of attributes defined for operational elements. |& "TABLE 2/T.541   w       Fieldcontent portion          Promptcontent portion               Resultcontent portion     Operational element       identifier (Note)  m  m  m          Operational element content type  d  d  d          Operational element content  d  d  d          XXNoteThis attribute may be omitted when the value can be unambiguously derived from the transmission sequence of the relevant elements.'X      XpXp$%%p&6.4.1.1 DataEntrySE 6.4.1.2 DataEntryProgramSE  XThe attribute firstsubprogram, defined in Recommendation T.564, is mapped to the reference attribute, defined in Recommendation T.441 (or currently in Annex A of this Recommendation).
