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.

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.

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.

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.

See UNTDID, Part 4, Chapter 2.3 UN/ECE UNSM - General Introduction, Section 1.

See UNTDID, Part 4, Chapter 2.3 UN/ECE UNSM - General Introduction, Section 2.

This section should be read in conjunction with the segment table which indicates mandatory, conditional and repeating requirements.

0010 UNH, Message header

A service segment starting and uniquely identifying a message. The message type code for the Drawing administration message is CONDRA.

Note: Drawing administration messages conforming to this document must contain the following data in segment UNH, composite S009:

0020 BGM, Beginning of message

A segment for unique identification of the Drawing administration document name, number and function.

0030 DTM, Date/time/period

A segment specifying the dates relevant to this document; e.g. the date, when the drawing administration in this message has been defined.

0040 AUT, Authentication result

A segment used to authenticate the message by exchanging a password or some other form of identification agreed between the business partners.

0050 AGR, Agreement identification

A segment will be used to identify the "type of agreement of the organisation of engineering or CAD files" that apply to the information given by this message.

0060 FTX, Free text

A segment with free text information, in coded or clear form, used for any textual information. In computer to computer exchanges, such text will require the receiver to process this segment manually.

0070 QTY, Quantity

0080 Segment Group 1: RFF-DOC-DTM-FTX

A group of segments used for quoting references and their relevant dates applicable to the message. For the building industry the following recommendation is given: in the first occurrence of this segment group the project references, if relevant, can be given, in order to identify the project to which this message relates. In any subsequent recurrence of this segment group, references to other messages (e.g. the original CONDRO when it is an update) or documents, relevant to this message, may be quoted.

0090 RFF, Reference

A segment for quoting the unique references which can be the project number to which this message is relevant, or, in the case of a reference to another message or document, that message or document's unique identifier.

Document details of the reference quoted in the previous RFF segment.

0110 DTM, Date/time/period

Date of a reference quoted in the previous RFF segment, e.g. project date or message/document date.

0130 Segment Group 2: NAD-LOC-FTX-INP-RCS-SG3-SG4

A group of segments identifying all the relevant parties with specific information about them that other business partner should know.

0140 NAD, Name and address

A segment identifying name and address of a party, in coded or clear form, and its function relevant to the Drawing Administration Message. This is to identify each partner involved in the future exchange of CAD files. It is recommended that where possible only the coded form of the party ID should be specified.

0150 LOC, Place/location identification

A segment giving more specific location information of the party specified in the NAD segment e.g. internal site/building number.

0160 FTX, Free text

This segment allows any narrative that may be needed to accompany the party name and address information specified in the previous NAD segment.

A segment to identify a communication type and number for the contact specified in the CTA segment.

0250 LOC, Place/location identification

This segment specifies the location of the contact specified in the previous CTA segment. In large organisations and construction projects it is possible that persons are not necessarily on the same internal site or construction site specified in the previous LOC segment in segment group 2. This segment also enables the specification of a more accurate internal site location.

0260 Segment Group 5: EFI-CED-RFF-DTM-QTY-SG6

A group of segments that refers through an external file identification to each of the external engineering/CAD files and giving additional information about each of the files.
