0. INTRODUCTION
This specification provides the definition of the Drawing administration message (CONDRA) to be used in Electronic Data Interchange (EDI) between trading partners involved in administration, commerce and transport.
1. SCOPE
1.1 Functional Definition
The message will be used for the administration of each exchange of a set of engineering/CAD files. It will give additional information about the files; for example, their nature, a list of their contents and technical information necessary to interpret them.
The whole process of exchanging engineering or CAD (Computer Aided Design) files between different parties within projects will be supported by EDIFACT messages. The message CONDRA is one of these messages.
1.2 Field of Application
The Drawing administration message may be used for both national and international applications. It is based on universal practice related to administration, commerce and transport, and is not dependent on the type of business or industry.
The following descriptions refer to the exchange of engineering/CAD files, but do not exclude any other type of "native" files, e.g. files originating from software packages and tools like word-processing, spreadsheet, DTP (Desk Top Publishing), graphics and so on.
1.3 Principles
CONDRA is the EDIFACT message to administer the exchange of engineering/CAD files. The message itself does not consist of any engineering or graphical information. This information will be transferred within files written in existing standard graphical exchange formats or native formats, referred to within the message as external file reference to identify each of these files. The nature of the engineering files and its content is not relevant for the syntax of the EDIFACT message.
All types of engineering/CAD files may be exchanged during a project's life cycle. The naming/structuring conventions, including project organisation and system environments can be defined in the EDIFACT message CONDRO (Drawing Organisation).
CONDRA will refer to the message CONDRO, previously received by the business parties, if there is additional information required about the project organisation, system environment and naming/structuring convention.
