7 Property distribution and model relationships schema

The following Express declaration begins the property_distribution_and_model_relationships_schema and identifies the necessary external references.

7.1 Introduction

The property_distribution_and_model_relationships_schema specifies the relationship between:

7.2 Fundamental concepts and assumptions

Within ISO 10303, the following are separate concepts:

NOTE 1   A property distribution over an idealised product, action or state can be recorded using ISO 10303-41, or using ISO 13030-53.

NOTE 2   A property distribution can have many discretised models created for it.

NOTE 3   The discretised model of a property distribution obtained by analysis can be recorded using either ISO 10303-104, or ISO 10303-53.

The ISO 10303 series of parts allows a single property distribution to be recorded in different ways, and allows a discretised model of a property distribution to be recorded in different ways. This part of ISO 10303 associates a discretised model of a property distribution with the corresponding distribution, irrespective of the way in which they are recorded.

7.3 property_distribution_and_model_relationships_schema type definitions

7.3.1 discretised_distribution_model_select   EXPRESS-G

The discretised_distribution_model_select type is an extensible list of alternate data types. It provides a mechanism to refer to instances of the data types included in the discretised_distribution_model_select type or in its extensions.

NOTE  The list of entity data types will be extended in application resources that use the constructs of this resource.

EXPRESS specification:

*)
TYPE discretised_distribution_model_select = EXTENSIBLE SELECT
   (model_property_distribution,
    state_definition);
END_TYPE;
(*

7.3.2 idealised_distribution_select   EXPRESS-G

The idealised_distribution_select type is an extensible list of alternate data types. It provides a mechanism to refer to instances of the data types included in the idealised_distribution_select type or in its extensions.

NOTE  The list of entity data types will be extended in application resources that use the constructs of this resource.

EXPRESS specification:

*)
TYPE idealised_distribution_select = EXTENSIBLE SELECT
   (domain_property,
    property_definition);
END_TYPE;

7.4 property_distribution_and_model_relationships_schema entity definitions

7.4.1 distribution_view_relationship   EXPRESS-G

A distribution_view_relationship is a relationship between: which indicates that the discretised model is a model of the property distribution.

EXPRESS specification:

*)
ENTITY distribution_view_relationship;
  id : identifier;
  name : label;
  description : OPTIONAL text;
  discretised_model : discretised_distribution_model_select;
  idealised_distribution : idealised_distribution_select;
END_ENTITY;
(*

Attribute definitions:

id: the identifier for the distribution_view_relationship.

name: the words by which the distribution_view_relationship is known.

description: the text that provides further information about the distribution_view_relationship. The value of this attribute need not be specified.

discretised_model: the discretised distribution model for numerical analysis.

idealised_distribution: the distribution for which a discretised model is created.

7.4.2 same_discretised_distribution_model   EXPRESS-G

A same_discretised_distribution_model is a relationship between records of a discretised distribution model, which states they each have the same meaning.

EXPRESS specification:

*)
ENTITY same_discretised_distribution_model;
  id : identifier;
  name : label;
  description : OPTIONAL text;
  equivalent_records : SET[1:?] OF discretised_distribution_model_select;
END_ENTITY;
(*

Attribute definitions:

id: the identifier for the same_discretised_distribution_model.

name: the words by which the same_discretised_distribution_model is known.

description: the text that provides further information about the same_discretised_distribution_model. The value of this attribute need not be specified.

equivalent_records: the records of a discretised distribution model which have the same meaning.

7.4.3 same_idealised_distribution   EXPRESS-G

A same_idealised_distribution is a relationship between records of an property distribution over an idealisation of product, action or state for analysis, which states they each have the same meaning.

EXPRESS specification:

*)
ENTITY same_idealised_distribution;
  id : identifier;
  name : label;
  description : OPTIONAL text;
  equivalent_records : LIST[2:?] OF idealised_distribution_select;
END_ENTITY;

Attribute definitions:

id: the identifier for the same_idealised_distribution.

name: the words by which the same_idealised_distribution is known.

description: the text that provides further information about the same_idealised_distribution. The value of this attribute need not be specified.

equivalent_records: the records of a property distribution which have the same meaning.
