Scope (English)

This part of ISO 15531 specifies a generic framework for the description of topological properties applicable to a wide range of one dimension domains. However, and given the needs of the other parts of ISO 15531, the developments made in this part are focused on the time domain, thus providing a universal, self consistent model, independent of any event that may occur, or has already occurred, at a given point in time. The time model specified in this part enables any software application to provide an accurate time reference to any related event, or sequence of events, whether in the past, in the present, or in the future. This time model may be used by any application that needs to reference events, actions, or sequences of action linked to time or intervals of time simultaneously. According to this, the scope of this part of ISO 15531 includes the following: - the description of the topological properties of an one dimension domain; - the description of the time model and of the related definitions; - the EXPRESS definitions of entities, attributes and schemas as prescribed in ISO 10303-11 (the reference manual of the EXPRESS language); - the EXPRESS-G diagrams of the model as prescribed in ISO 10303-11. The following are out of the scope of this part of ISO 15531: - the description of any kind of measure theory or measure method - elements and domains of more than one dimension - the modelling of any event as described in ISO 10303-41 EXAMPLE Since their domain dimension is greater than one, squares, rectangles, triangles,..as well as cubes and spheres are out of the scope of this part of ISO 15531.
