PDM-UG: Document format property
From WikiSTEP
This page belongs to the PDM Usage Guide.
The format related properties of documents are represented accordingly to the general scheme outlined above. To indicate that the property is related to document format the used representation must be instantiated with:
This capability specifies the format of a document object. At least one of the items shall be specified for each instance of this property representation. Aspects of the format property can be modeled via the following instantiations of descriptive_representation_items collected in the above representation.
| requirement | descriptive_representation_item.name | Descriptive_representation_item.description |
| the convention that was used to structure the information in the characterized object | 'data format' | Where applicable the following values shall be used: 'DXF', 'IGES', 'STEP AP203', 'STEP AP214', 'TIFF CCITT GR4', 'VDAFS', 'VOXEL' |
| the character code that is used for the stored data | 'character code' | Where applicable the following values shall be used: 'US ASCII 7bit', 'ISO LATIN-1', 'EBCDIC', 'binary' |
| the dimensions of a physical presentation | 'size format' or 'size format standard' where applicable | e.g., 'ISO A0', '0.2 x 0.4 x 0.4 meters' |
The Instance Model: STEP exchange file format (ISO10303 Part 21 syntax)
/* Entities #140 to #200 assign document format parameters to 'file1' (#80)
#140 = PROPERTY_DEFINITION('document property', '', #80);
#150 = PROPERTY_DEFINITION_REPRESENTATION(#140, #160);
#160 = REPRESENTATION('document format', (#170, #190), #200);
#170 = DESCRIPTIVE_REPRESENTATION_ITEM('data format', 'VOXEL');
#190 = DESCRIPTIVE_REPRESENTATION_ITEM('character code', 'binary');
#200 = REPRESENTATION_CONTEXT('', 'document parameters');
