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 one
       project will be supported by EDIFACT messages. The message
       CONDRA is one of these messages.

1.2   Field of Application

       This message type may be applied for both national and
       international trade. It is based on universal practice 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 to be exchanged during a
       project's life cycle and its naming/structuring conventions,
       including project organisation and system environments are
       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.

       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.

       This segment conveys exchange information like the number of
       engineering/CAD files and their total size (volume) that form
       part of the exchange of this message and to which this message
       refers.


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.

0100      DOC, Document/message details
          Document details of the reference quoted in the previous RFF
          segment.

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.

0170      INP, Parties to instruction
          A segment that gives each of the receivers their specific
          instructions for what they should do with this message and
          the files to which this message refers.

0180      RCS, Requirements and conditions
          A segment that gives specific requirements to each of the
          receivers of this message, e.g. action request.


0190      Segment group 3: RFF-DTM
          This segment group can be used to quote specific references
          for each partner, that may be needed for internal use.

             In this segment specific internal references will be
             quoted, as and when required.

0210         DTM, Date/time/period
             A segment specifying the date and/or time details related
             to the party's specific internal references.


0220      Segment group 4: CTA-COM-LOC
          A group of segments giving contact details of the specific
          person or department within the party identified in the NAD
          segment.

0230         CTA, Contact information

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.

0270      EFI, External file link identification

             previous BII segment it is possible to refer to other
             messages/documents on other levels of the structure of
             the engineering/CAD file identified in the previous EFI
             segment. It is also possible to refer to other levels
             which are part of a different engineering/CAD file than
             the one identified in the previous EFI segment. If
             needed, here should also be made a reference to a
             contractual document or to a revision number.

0470            RFF, Reference
                An ID number will be used to refer to either another
                message/document or to another engineering/CAD file.

                   to are quoted in this segment.


0510            Segment group 9: SEQ-BII-RFF-GIS-DTM-IMD
                This segment group will be used when a reference is
                made to another specific level in the structure of an
                engineering/CAD file.
                If in the previous RFF segment a standard dummy value
                is quoted, the level referred to is part of the
                engineering/CAD file identified in the previous EFI
                segment. If, however, in the previous RFF segment any
                other value is quoted, the level described in the
                following BII segment is part of the engineering/CAD
                file identified by the ID number.

0520               SEQ, Sequence details
                   A segment identifying the beginning of a CAD-file
                   by a sequential  number.

0530               BII, Structure identification
                   This segment will through a structured index code
                   uniquely identify the level referred to.

                   Through an "index system", updates (versions) can
                   be recorded in a reference number. In this segment
                   the version of the level referred to can be quoted.

0550               GIS, General indicator
                   This segment is used to define the level type
                   identified in the previous BII segment; like, for
                   example, drawing sheet, view, layer group and
                   layer.

0560               DTM, Date/time/period
                   Date/time details of the level that is referred to
                   are quoted here.
