Representations of the operations themselves are not specified here; the mechanisms provided in this document allow the use of entity data types defined in other parts of ISO 10303 for that purpose.The following are within the scope of ISO 10303-55:2005: the specification of sequences of constructional operations for the generation of any kind of explicit representation or model; the hierarchical structuring of constructional sequences; the embedding of explicitly defined elements in constructional sequences for the representation of hybrid models; the use of representation_item definitions from other parts of ISO 10303 to represent constructional operations for instances of those representation_items; the definition of a dual representation by association of a procedural model with an explicit "current result" model, the latter acting as a representative example of the parametric family of models defined by the former; the association of design rationale information with a procedural model; the identification, in a procedural model, of explicit elements selected by interactive picking from the visual display of the model in the sending system; the identification, in a procedural model, of constructional operations that can be suppressed for purposes of model simplification; specialization of the foregoing capabilities for the procedural representation of shape models.

ISO 10303-108:2005 specifies the resource constructs for the representation of model parameters and constraints in CAD or other kinds of models, together with the mechanisms necessary for associating them with geometric or other elements of transferred models. The use of these capabilities potentially allows certain aspects of the behaviour of a model in its originating system to be conveyed together with the basic model itself. The intention in transferring this additional information is to provide the receiving system with data that will enable it to reconstruct corresponding behavioural characteristics in the model following the transfer. Ideally, this will enable the model to be edited in the receiving system just as as though it had been created there. That would not be possible without the exchange of what is known as design intent information. ISO 10303-108:2005 enables the capture and transfer of an important aspect of design intent. The following are within the scope of ISO 10303-108:2005: parameterization of models through the association of variables with quantities occurring in them, including dimensional values; constraints defining mathematical relationships between variable parameters; constraints on models expressed as descriptive relationships between their constituent elements or attributes of those elements; specialized descriptive constraints corresponding to the geometric constraints commonly used in product shape modelling (e.g., parallelism or tangency between geometric elements); applications of parameterization and constraints to two- and three-dimensional shape models; specialized representations for two-dimensional geometric sketches or profiles; representation of models that are incompletely defined in the sense that certain values in the model may be regarded as not fully constrained. The following are outside the scope of ISO 10303-108:2005: procedural or history-based model representations, expressed in terms of sequences of constructional operations; implicit or procedurally defined constraints, inherent in the operation of constructional operations; solution methods for systems of constraint equations; form features of shape models; behaviour of a system in which a variational model is edited following a transfer; considerations of accuracy in constraint satisfaction. The following notes apply to the excluded capabilities. Procedural or history-based representations are the subject of ISO 10303-55. Methods of solving constraint equations are the responsibility of the application systems involved in the exchange. ISO 10303-108:2005 merely transfers the constraint relationships that need to be solved. Various other parts of ISO 10303 provide representations for different application-oriented views of form features. The information transmitted by the use of ISO 10303-108:2005 is intended to allow implementers to provide 'reasonable' or 'intuitive' behaviour by receiving systems following the transfer of a model in the circumstances mentioned above, but ISO 10303-108:2005 does not prescribe the detailed nature of such behaviour or of its presentation to the system user. Accuracy considerations are essentially the same in the ISO 10303-108:2005 context as those arising generally in the geometric modelling of product shape. Means are provided elsewhere in ISO 10303 for addressing accuracy issues.

This part of ISO 10303 specifies the use of the integrated resources necessary for the scope and information requirements for Technical Data Packages (TDPs) (see 3.5.28) to be exchanged among product data management systems. Each enterprise uses content, format, and the level of configuration control as parameters when establishing its product exchange or access requirements among business partners. Because of the diverse set of products, product data, and lifecycle processes PDM systems support, this part of ISO 10303 allows many combinations of these parameters and their values. Using a defined set of these parameters, the disclosure of product information needs to be sufficient to satisfy the business purpose of the TDP. NOTE 1 TDPs may be prepared to a level where the product information is sufficient to evaluate a product definition concept. Or a TDP may be prepared to a level where the product information is sufficient to enable full design disclosure (see 3.5.9). Requirements for this part of ISO 10303 were derived from functions that create and use TDPs and reside throughout the product's life cycle. The key informational aspects addressed in this part of ISO 10303 are shared and exchanged throughout the product's life cycle. NOTE 2 Within a product's life cycle, there are many functions that create and use the technical information about a product. Figure 3 illustrates the functional usage of technical data within each life cycle phase of a product. The largest percentage of the technical data is developed in the concept development, concept and validation, and product and process development lifecycle phases. The operations and support lifecycle phase, for most products or commodities, is the longest and is impacted the greatest by the quality and usability of the TDP information. The production lifecycle phase typically has the second largest usage of the information contained within the TDP. In the production and product process development lifecycle phase, TDP data is used to build and deliver the product. NOTE 3 The application activity model in annex F provides a graphical representation of the processes and information flows that are the basis for the definition of the scope of this part of ISO 10303.
