Application module: Activity as realized | ISO/TS 10303-1259:2004(E) © ISO |
ISO 10303 is an International Standard for the computer-interpretable representation of product information and for the exchange of product data. The objective is to provide a neutral mechanism capable of describing products throughout their life cycle. This mechanism is suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases, and as a basis for archiving.
This part of ISO 10303 specifies a module to record that an activity has occured - or has at least started. It distinguishes the historical record from plans or intentions. Activity_as_realized may record something done to a product design, document, plan, task description or to an actual product. Activities on an actual product may include repair, maintenance, replenishment and simple observations about the condition of the product. The function of activity_as_realized is as collector of the historical record.
The concept activity_as_realized is introduced to distinguish between the activity (the data that is created in order to describe the activity) and activity_as_realized (the data that records what was actually occurred). In general, the data recorded against the two will be different. However, even if the intention is carried out exactly, activity_as_realized records that the activity occurred, and relates this to the activity as specified through the entity activity_happening.
Clause 1 defines the scope of the application module and summarizes the functionality and data covered. Clause 3 lists the words defined in this part of ISO 10303 and gives pointers to words defined elsewhere. The information requirements of the application are specified in Clause 4 using terminology appropriate to the application. A graphical representation of the information requirements, referred to as the application reference model, is given in Annex C. Resource constructs are interpreted to meet the information requirements. This interpretation produces the module interpreted model (MIM). This interpretation, given in 5.1, shows the correspondence between the information requirements and the MIM. The short listing of the MIM specifies the interface to the resources and is given in 5.2. A graphical representation of the short listing of the MIM is given in Annex D.
In this International Standard, the same English language words may be used to refer to an object in the real world or concept, and as the name of an EXPRESS data type that represents this object or concept.
The following typographical convention is used to distinguish between these. If a word or phrase occurs in the same typeface as narrative text, the referent is the object or concept. If the word or phrase occurs in a bold typeface or as a hyperlink, the referent is the EXPRESS data type.
The name of an EXPRESS data type may be used to refer to the data type itself, or to an instance of the data type. The distinction between these uses is normally clear from the context. If there is a likelihood of ambiguity, either the phrase "entity data type" or "instance(s) of" is included in the text.
Double quotation marks " " denote quoted text. Single quotation marks ' ' denote particular text string values.
