Introduction

Recommendation T.400 is one of a set of the T series of Recommendations to facilitate the interconnection of telematic systems and terminals. It is related to the other CCITT Recommendations in the set as defined by the Reference Model for OSI (X.200) and also makes provision for non-X.200 existing telematic services.

1	Scope

Recommendation T.400 serves as an introduction and guide to Recommendations in the T.400 series, and associated Recommendations in the T.500 series that make use of the T.400 series.

2	The T.400 series and the related T.500 series of Recommendations

Recommendations in the T.400 and T.500 series set the grounds for the architecture, the transfer and the manipulation of documents in current and future telematic services.

2.1	Document architecture, transfer and manipulation

The T.400 series of Recommendations specifies how documents are to be described and which are the rules for transferring and manipulating such documents.

2.1.1	T.410 series of Recommendations: Open document architecture (ODA) and interchange format

The T.410 series of Recommendations defines the document architecture, i.e. rules for structuring documents, and the interchange format, i.e. rules for representing documents. It also gives rules for defining document application profiles, i.e. the specifications of the features of a document to be used in an application.

2.1.2	T.430 series of Recommendations: Document transfer and manipulation (DTAM)

The T.430 series of Recommendations defines document transfer services and protocols. It also gives rules for defining communication application profiles, i.e. the specifications of the communication support functions, service classes and functional units to be used in a communication applications.

These Recommendations make use, in turn, of functions defined by other Recommendations in the OSI environment such as those in the X.400 series and in the X.200 series. Annex B of this Recommendation shows how the T.410 series relates to the X.400 and X.200 series in the OSI environment.

Annex E of Recommendation T.411 describes the use of the X.400 series of Recommendations to transfer documents conforming to the T.410 series.

The interchange format defined in the T.410 series constitutes an application context as defined in Recommendation X.226. The abstract syntax of the application context is defined in Recommendation T.415.

2.1.3	Recommendation T.441: Document transfer and manipulation (DTAM) - Operational structure

Recommendation T.441 defines the concept of the operational structure, which enables the manipulation of documents or parts of documents, and gives an outline of the principles and use of the operational structures.

2.2	Application profiles

Each Recommendation in the series T.500 through T.559 specifies either a document application profile based on the rules of T.411, or a communication application profile based on the rules of T.431, or an operational application profile based on the rules of T.441.

2.3	Terminal and gateway characteristics

Each Recommendation in the series T.560 through T.599 specifies terminal characteristics or gateway characteristics for equipments using application profiles in the T.500 through T.559 series.
