0.    INTRODUCTION

       This specification provides the definition of the Drawing
       organisation message (CONDRO) 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 CONDRO is intended to describe the general
       (project) organisation and structure, valid for a whole project
       or environment.
       
       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
       CONDRO is one of these messages.

1.2   Field of Application

       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

       CONDRO is the EDIFACT message to initiate the future exchange
       of engineering/CAD files, and does not consist of any
       engineering or graphical information. Its aim is to acquaint
       the participant of a project with the existing organisation,
       the used computer environment, the agreed conventions for
       structuring/naming the transferred data and in a second
       application to announce any changes to the above mentioned
       agreement.
       The exchange of all engineering and graphical information is
       administered by the EDIFACT message CONDRA (Drawing
       Administration).
       This information will be transferred by existing standard
       graphical exchange formats or native formats.
       Changes in the agreements and conventions should be minimised
       and be made at the beginning of a project or exchange process.
       Consequently it is not necessary to repeat the description of
       the files' organisation with every exchange of engineering/CAD
       files. This means not only a reduction of data volume at each
       exchange, but also avoiding the exchange of redundant data.

4.    MESSAGE DEFINITION

4.1   Data Segment Clarification

       This section should be read in conjunction with the Segment
       Table which indicate 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 organisation message is
       CONDRO.
       
       Note: Drawing organisation messages conforming to this document
       must contain the following data in segment UNH, composite S009:

       Data element  0065 CONDRO
                     0052 D
                     0054 98A
                     0051 UN

0020   BGM, Beginning of message
       A segment for unique identification of the Drawing Organisation
       name, number and function.

0030   DTM, Date/time/period
       A segment specifying the dates relevant to this document; e.g.
       the date the agreement of the drawing organisation information
       in this message has been defined or redefined (in case of
       changes).

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   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, should be given, in order to identify the project to
       which this message relates. In any later 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.

0080      RFF, Reference
          A segment for quoting the unique references which can be the
          project number for which this message is relevant, or, in
          the case of a reference to another message or document, that
          message or document's unique identifier.

0090      DOC, Document/message details
          Document details for the reference quoted in the previous
          RFF segment.

0100      DTM, Date/time/period
          Date of a reference quoted in the previous RFF segment, e.g.
          project date or message/document date.

0110      FTX, Free text
          This segment can contain any textual information relevant to
          the reference quoted in the previous RFF segment, e.g. a
          small project or message/document description and/or other
          narrative, for additional information.


0120   Segment group 2: NAD-LOC-FTX-SG3-SG4
       A group of segments identifying all the relevant parties with
       specific information about them that other business partner
       should know.

0130      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
          Organisation 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.

0140      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.

0150      FTX, Free text
          A segment giving more specific location information of the
          party specified in the NAD segment e.g. internal
          site/building number.


0160      Segment group 3: RFF-CED-DTM
          This segment group has two functions:
          
          Firstly, it can be used to quote specific references for
          each partner for internal use. Examples of references: a
          partner may require a internal project number or a DP
          number.
          
          Secondly, the main function of this segment group, is to
          describe for each partner his internal computer environment,
          from the hardware platform and operating system to the
          software implemented.
          For each partner several environments may be described, as,
          particularly in large organisations, different environments
          can be in use simultaneously. Each environment will be
          identified through a unique reference number specific to
          that partner.

0170         RFF, Reference
             In this segment specific internal references will be
             quoted, as and if required.
             When this segment group is used to describe the computer
             environment, this segment segment which will specify the
             unique reference number by which, in future, the
             following computer environment details for this party can
             be identified.

0180         CED, Computer environment details
             By repeating this segment, it will describe, at each
             occurrence, one of the party's computer environments,
             identified in the previous RFF segment. The computer
             environment details will consist of, for example,
             hardware platform, operating system, software in use,
             converter etc.

0190         DTM, Date/time/period
             A segment specifying the date and/or time details related
             to the environment details.


0200      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.

0210         CTA, Contact information
             A segment to identify a person or department, and their
             function, to whom communications should be directed.

0220         COM, Communication contact
             A segment to identify a communication type and number for
             the contact specified in the CTA segment.

0230         LOC, Place/location identification
             This segment specifies the location of the contact
             described 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.


0240   Segment group 5: DOC-INP-RFF-MEA-SG6
       In this segment group a "contractual document" can be described
       that is relevant to a certain project or project phase. A
       contractual document consists of one or more computer files
       which be quoted and linked by a file identification to the
       corresponding contractual document.

0250      DOC, Document/message details
          This segment will give the document details of the
          contractual document.

0260      INP, Parties and instruction
          This segment conveys for each receiver instructions of what
          to do with the contractual document.

0270      RFF, Reference
          A segment to indicate the unique reference number of the
          contractual document.

0280      MEA, Measurements
          This segment will give details about the scale used in the
          contractual document.


0290      Segment group 6: EFI-CED-DTM
          In this segment group files may be identified which will
          form part of the previously quoted contractual document.
          These computer files are external ones which will not
          necessarily be part of the exchange of the message.

0300         EFI, External file link identification
             This segment will identify each file, that is part of the
             contractual document, by quoting their name and a number.

0310         CED, Computer environment details
             The segment will give additional information about the
             file identified in the previous EFI segment, like for
             example, conversion details.

0320         DTM, Date/time/period
             This segment will convey the date/time details of the
             computer file identified in the previous EFI segment.


0330   Segment group 7: BII-GIS-DTM-IMD-RFF-QTY-SG8
       This segment group can be used to record two types of
       information:
       
       Firstly, information about all kinds of lists (like naming
       conventions, libraries used etc.) with their object
       descriptions and other details relevant to the exchanged
       engineering/CAD files.
       
       Secondly, detailed descriptions about the structure of the
       engineering/CAD files.
       
       In both cases, the information is organised hierarchically in
       several levels. The level will be identified first and will
       contain its own specific set of information, like technical
       data, references, etc.
       This segment group therefore varies depending on the type of
       information, the application of the segments and whether they
       will be used or not.

0340      BII, Structure identification
          This segment will, through a structured index code, uniquely
          identify the set of information following this segment.

0350      GIS, General indicator
          This segment is used to define the type of information
          (lists or engineering/CAD file structure) appearing in this
          segment group identified by the previous BII segment.

0360      DTM, Date/time/period
          Date and time details relevant to the set of information
          identified in the previous BII segment (e.g. list version
          date).

0370      IMD, Item description
          This segment records the details of the set of information
          identified in the previous BII segment (e.g. descriptions of
          the hierarchical levels or objects, part of the lists).

0380      RFF, Reference
          This segment will give a reference to another set of
          information (e.g. engineering/CAD file structure referring
          to naming conventions given in a previously-supplied list).

0390      QTY, Quantity
          This segment conveys the number of objects within the next
          higher level of a list.


0400      Segment group 8: LOC-DIM-QTY-MEA
          A group of segments to record the technical data of the set
          of information identified in the previous BII segment.

0410         LOC, Place/location identification
             This segment will give detailed information of the
             position in a co-ordinate system in case the structure of
             an engineering/CAD file is described (e.g. the
             co-ordinate details of a layer group or a layer in a CAD
             file).

0420         DIM, Dimensions
             Dimensions (like unit of measurements) relevant to an
             engineering/CAD file can be quoted in this segment.

0430         QTY, Quantity
             A segment identifying the quantities of objects in lists
             or engineering/CAD files.

0440         MEA, Measurements
             For an engineering/CAD file, the scale used can be quoted
             in this segment.

0450   UNT, Message trailer
       A service segment ending a message, giving the total number of
       segments in the message and the control reference number of the
       message.
