Note: There is a newer version of this specification see VEC 2.1.0

The DocumentVersion is one of the two anchors for PDM information in the VEC. All technical information about a PartVersion is contained in one or more documents. The documents are containing the actual content of the VEC since all Specifications are an element of a document.

Derived Classifiers


Name Type Mult. Description Owning Classifier
abbreviation LocalizedString 0..*

Room for a short name of the Item. In case of a document the attribute is wanted to contain its title.

description AbstractLocalizedString 0..*

Room for additional, human readable information about the ItemVersion. e.g. Buchsengehäuse 26-polig

companyName String 1

Defines the publishing company of the ItemVersion. The companyName is part of the main identifier of an ItemVersion together with the corresponding number (partNumber or documentNumber) and version (partVersion or documentVersion).

processingInstruction Instruction 0..*

Processing instructions for the application of the part or the document.

documentNumber String 1

The documentNumber is the major identifier of a DocumentVersion. The format is user defined and respectively company specific. Over all VEC-documents a DocumentVersion-instance can be trusted to be identical if the combination of documentNumber, documentVersion and companyName is identical.

documentType String 0..1

The type of the document. This should be an enumeration of values defined in a conformance class. Typical values would be example: WiringDiagram, HarnessDrawing, etc.

documentVersion String 1

The documentVersion specifies the version index of a document (see also documentNumber).

creatingSystem String 0..1

The creatingSystem specifies the computer application or the machine which is used to create the document.

dataFormat String 0..1

The dataFormat specifies the convention that was used to structure the information in the document. This is useful if the DocumentVersion is actually a pointer to an external document, which is not contained in the VEC or if the content of this DocumentVersion was automatically generated by the extraction of the information out of the original document.

fileName String 0..1

If this DocumentVersion is a link to an external document (e.g. a ComponentSymbol), then the fileName attribute points to the file containing the original document. To use this attribute is only valid, if the original document is distributed along with the VEC-file e.g. in a ZIP-archive. It must not point to any file location which is not part of the bundle provided together with the VEC-file (e.g. a File on a central server file share).

location String 0..1

The location specifies where a document can be found in a digital or physical data storage system.

numberOfSheets String 0..1

The number of sheets contained in the document.
