General

The concept of Profiles for OSI, and the structure of the international Standardized Profiles that document them, are defined in ISO/IEC TR 10000-1. Such Profiles are divided into a number of different classes and subclasses. Two of these classes contain sub classes comprising functions of the Virtual Terminal Basic Class Service and Protocol specified in the base standards ISO 9040 and ISO 9041 These are the Application Profiles (A-Profiles) and the interchange Format and Representation Profiles (F-Profiles).

The relationship between A-Profiles and F-Profiles is described in 7.3.2 of ISO/IEC TR 10000-1 and is as follows Application Layer base standards require, implicitly or explicitly, the structure of information carried or referenced by them to be specified Ior each instance of communication It is the purpose of F-Profiles to specify such information structures. Particular functional requirements may then be met by the combination of an A Profile with one or more F-Profiles

Establishment of a VT-association involves the selection by negotiation of a particular Virtual Terminal Environment profile (VTE-profile), and of particular values fa any arguments of that VTE-profile. The VTE-profile specification, and possibly also the values of certain VTE-pro We arguments, may in tum reference the definitions of VT control object types and assignment types. These VTE-profiles, contra object types and assignment types are thus information structures that require exploit reference within the VT protocol Particular instances of these structures are fully defined within the base standards, but the base standards also provide for further instances to be defined by registration Each registered Instance constitutes an F-Profile within the framework a ISO/IEC TR 10000.

The Virtual Terminal Basic Class Service and Protocol may be used to realise a wide range a distinct functions Particular functions may be realised through the selection of appropriate VT functional units, F-Profiles and other VTE- profile argument values. The specification of the selection required to realise a particular function and to promote interoperability constitutes a Virtual Terminal A-Profile within the framework of ISO/iEC TR 10093 The three international Registers a VT information structures and the specifications of VT Application Profiles are each published as a separate multi-part ISP as fallows:

- ISO/IEC ISP 11184 is the Register of VTE-profiles;

- ISO/IEC ISP 11185 is the Register of contra object type definitions;

- ISO/IEC ISP 11186 is the Register a assignment-type definitions;

- ISO/IEC ISP 11187 contains the specifications of VT Application Profiles

This part of ISO/IEC ISP 11185 contains the definition of a contra object type that may be used to define horizontal tabulation stops for use during data entry into a d splay object The manner a use cl the tabulation stops does not form part of this definition and should be specified by the VTE-profile that references this control object.
