Its purpose is to specify a document architecture level and a content architecture level, and to select an interchange format class suitable for videotex interworking as defined in configuration 1 of Recommendation F.300 and in Recommendation T.564. 2 Field of application This Recommendation defines a document that is in conformance with the T.400 Series of Recommendations and that allows interworking between two videotex services using configuration 1 defined in CCITT Recommendation F.300 and Recommendation T.564. The videotex documents are interchanged only in a formatted form, allowing the recipient to reproduce them as intended by the originator. This document application profile is defines the features of the document structure that can be interchanged. 3 References - Rec. F.300: Videotex service - Rec.

Therefore the purpose of this document application profile is to allow the recipient to image the layout of the interchanged document as intended by the originator. This section specifies the functional description of the features supported by this document application profile. 5.2 Logical characteristics Not used. 5.3 Layout characteristics 5.3.1 Layout document structure At a given time a document contains one single page which contains one or more blocks. The content of the block is: - "Videotex" content. Fascicle VII.7 - Rec. T.504 3 5.3.2 Document structure elements 5.3.2.1Page format The page format is expressed in accordance with the definition of the videotex service or videotex terminal, by using scaled measurement units. The relation between BMUs and SMUs is specified in the document profile. 5.3.2.2Block size The position and the dimension of the blocks are restricted to be equal to those of the page. Block size not equal to page is for further study. 6 Definition of the document application profile 6.1 Overview 6.1.1 Document architecture level The document application profile makes use of document architecture class FDA as defined in Recommendation T.412. The document architecture level includes the following structure: - a specific layout structure. The document architecture level is defined in Tables 1/T.504, 2/T.504 and 3/T.504. 6.1.2 Content architecture level The content architecture level that may be used in documents conforming to this document application profile is as follows: - "Videotex" Details are specified in Recommendation T.101. 6.2 Document profile level The document profile level used in this document application profile is defined in Table 4/T.504. Every document interchanged in accordance with this document application profile must include a document profile. 6.2.1 Interchange format class The interchange format class used in this document application profile is "B" as defined in Recommendation T.415. 6.2.2 Definition of document structure The document structure contains a specific layout structure. The number of hierarchical levels is 3, namely: - document layout root; - page; - block. All these levels are mandatory. At most one content portion can be associated with one block. 6.3 Specification of attributes The attributes applicable to constituents of the layout structure are defined in Tables 1/T.504 and 2/T.504, using the following notation: --- attribute not applicable; m attribute is mandatory; nm attribute is non-mandatory; d attribute is defaultable; * exceptionally not used by this document application profile. 4 Fascicle VII.7 - Rec.

The unit scaling factor is defined by the attribute "unite scaling" within the document profile. The "nominal page size" within the attribute "medium type" defines the number of rows and columns to be imaged on the screen by the videotex application in terms of SMUs. For the block, the position and dimensions are those of the page. Note 2 - It has to be taken into account that within the national videotex systems the position is usually determined by (1,1). 6 Fascicle VII.7 - Rec.
