Internet-Draft             EPC to DBS Interface             January 1997

1    Introduction

     An EPC is used to electronically retrieve the information contained
     within the printed parts books.  This is usually accomplished
     with a highly graphical interface.  In addition, most EPCs run
     on Windows-based PC's.  The EPC is only a lookup/ reference
     tool, but it does allow for the creation of "pick lists".  A pick
     list places a number of part numbers along with the corresponding
     quantities requested into a list.

     A DBS is used to catalog the Part Numbers available at an Equipment
     Dealer/ Distributor's location. Typical systems allow for the entry
     of Part Numbers, Quantity on Hand, Quantity on Order, Bin Location,
     Retail Price, Customer Price, Suggested Retail Price, etc...  These
     systems typically run on Unix based mainframes.

     With the rising use of EPCs in the outdoor power, agricultural,
     and construction equipment industries the need to share data in
     real-time with the legacy DBSs has become a key issue
     to successfully installing these systems.  A number of
     proprietary, operating system specific, and inflexible
     protocols have been proposed to handle these interactions.
     It is the intent of this Internet-Draft to describe an interface
     which has been successfully implemented that overcomes the
     limitations of previous interfaces.


2    Key Features

     The key features of this interface are as follows:

     - expand-ability  The framework is expansion-friendly

     - network independent  Although tcp/ip is the only
       protocol currently used to implement this interface
       there other protocols that share TCP's key features
       such as ISO 8072 could be used instead.

     - client-server

     - decoupling  The DBS and the EPC can each be upgraded
       without requiring a simultaneous upgrade in the other.  This
       is particularly important in environments with EPC's from
       several vendors being used simultaneously.

     - operating system independent

     - real-time  The user always sees the most current
       information.

Internet-Draft          EPC to DBS Interface             January 1997

3    Protocol

     The protocol is very simple.  Data is transferred in both
     directions using the same format.  Each line in the transfer
     is split up into four pieces.

     The first character is the `table'.  Some might feel more
     comfortable referring to this as the `file' or `database',
     but since table is a less ambiguous term that is what this
     I-D will use.  Examples of tables would be the part, stock
     part, pick list header, and pick list detail.  Each of these
     has a unique character.  The capitalization of this character
     is also significant.  It is used to indicate the beginning of
     records.  If the table character is a capital, that indicates
     the beginning of a record.  If it is lower case, then it is a
     continuation of the current record.  If the table is `#' then
     the rest of the line is ignored and is a comment.  These
     comments are not intended to be displayed to the user.  They
     are there merely to facilitate the debugging process.

     The second character is the `field'.  Within each table
     characters are defined for individual fields such as
     `manufacturer', `part number', and `description'.  Again, the
     capitalization of the characters is relevant.  If a field is
     a capital letter it indicates information that is known.  If
     it is lower case it indicates information that is being
     requested.  The `*' character can be used to request all
     available information.  Although no one has currently
     implemented it, it is possible for this character to be used
     to delete or count matching records.

     The third piece is simply a space (ASCII 32).

     The fourth piece consumes the rest of the line.  It is the
     `value'.  Monetary values are expressed in pennies. $123.45
     would be passed as `12345'.  The line should be terminated
     with a UNIX (LF) or DOS (CR/LF) line terminator.  There
     should be no white space between the end of the value and the
     line terminator.  If there is, it should be ignored.  White
     space includes space, tab and other control characters.  For
     purposes of this I-D ASCII 1-32 except LF should be
     considered white space.

     One particularly important point of this interface is the
     decoupling of the EPC and DBS.  To achieve this version
     numbers are used.  As long as the major number hasn't
     changed, both ends should cope gracefully with new tables and
     fields.  The EPC or the DBS may have fields which the other
     does not.  That these fields might be sent should not crash
     the interface, or cause the user to see an error message.
     The current version number is 2.1.


Sheppard                                                        [Page 3]


Internet-Draft             EPC to DBS Interface             January 1997

     In the tcp/ip realm it has become common practice for the DBS
     to accept connections on port 2345. Many clients also rely on
     resolving `bsihost' to the IP address of the server.

     Also the system information passed in the `$' table should be
     the first thing sent.  The client should send in the order
     `H' then `V' then the other optional `$' fields.  The server
     should start with a `V' that is the same major number as the
     client.  The other `$' fields should not be passed since they
     would be superfluous.

     The client and server should both finish by sending a final
     line of `QUIT' or `DONE'.  While `DONE' may still be in use,
     `QUIT' is preferred since it is more consistent with other
     tcp/ip protocols.  Version 2 clients and servers should
     support both, but Version 3 and greater clients and servers
     should support and send only `QUIT'.

     Appendix A lists the currently defined tables and fields.

4    Examples

     These examples are provided to help make the protocol easier
     to understand.

4.1  Part Queries

     The EPC might send the following to the DBS:

          $H N-Compass
          $V 2.1
          $U tom
          SE XYZ
          sI 12345
          s*
          QUIT

     In this case 'tom' is on 'N-Compass' running a version 2.1 EPC
     and is requesting information on part
     12345 from manufacturer XYZ.

     The DBS might respond with

          $V 2.1
          QUIT

     This would indicate that no information is available.  Its
     likely that the DBS does not have that part on file.
     The DBS could have responded with:




Sheppard                                                        [Page 4]


Internet-Draft              EPC to DBS Interface             January 1997

          $V 2.1
          SE XYZ
          sI 12345
          sB top shelf
          sC 123
          sO 2
          sQ 550
          sD what-cha-ma-jig
          QUIT

     This indicates that the EPC should display the information to
     the user.  The DBS also might have responded with

          $V 2.1
          SE XYZ
          sI 12345
          sB top shelf
          sC 123
          sO 2
          sQ 550
          sD what-cha-ma-jig
          sA don't sell this without grease and instructions
          sA Bob knows how to install this
          QUIT

     In this case, the dealer or the manufacturer have added
     comments for this part.  If possible this information should
     be displayed to the user in the EPC.

     Another example of a query from the EPC is

          $H N-Compass
          $V 2.1
          $U tom
          TE XYZ
          tI 12345
          tD What-Cha-Ma-Jiggy
          tZ US
          tC 123
          tS 456
          t*
          SE XYZ
          sI 12345
          s*
          QUIT

     In this case the EPC knows information about the part that is
     relevant in the US.  The DBS should store this information
     and use it to compute markups (actual customer prices are
     calculated).

Internet-Draft             EPC to DBS Interface             January 1997

4.2  Pick Lists

     An example of a simple pick list sent from the EPC would be:

          $H N-Compass
          $V 2.1
          $U tom
          HI 1
          hN sale for maury
          hS S
          DH 1
          dI 1
          dQ 2
          dM XYZ
          dP 12345
          DH 1
          dI 2
          dQ 4
          dM XYZ
          dP 67890
          QUIT

     In this case two parts are to be invoiced.  The first part is
     quantity 2 of manufacturer `XYZ' part `12345'.  The second
     part is quantity 4 of manufacturer `XYZ' part `67890'.

5    Mass Updates

     Support for this feature is not necessarily available on all
     current implementations.  If the user would like to have the
     DBS updated with information from the EPC, they should be
     able to start a mass update.  The mass update would include
     the normal $H and $V information.  Then T records would be
     passed.

6    Security Considerations of this Memo

     Most vendors involved have not been concerned about security
     and all current implementations make few if any security
     checks.  The host and user information included in the
     information from the client is assumed by most servers to be
     correct.  While on a small private network this may or may
     not be acceptable, something such as SSL or PGP should be
     used in Internet environments.

7    Summary of tables and fields

     Table     Field       Description

     #          Comments   This line should be ignored.  Use of
                           comments for debugging purposes is
                           recommended.

     $          B          Branch. A query option.  This is
                           not required

     $          C          Customer Number. A query option.
                           This is not required

     $          H          Hostname. The $H line must be
                           the first line the EPC sends to the DBS.
                           The hostname need not be sent by the DBS
                           to the EPC.

     $          O          Order Type. A query option. This
                           is not required.

     $          S          Source Type. A query option. This
                           will either be C for Counter, M for
                           Machine or W for Work Order.  This is not
                           required.

     $          U          Username. A query option. This is not

     $          V          Version. This is a floating point
                           number.  There will never be a
                           "version 4.5.3" or "version 2.1.2.12.9.5".
                           For this release the version "2.1".
                           Sending it is required and it must be the
                           second record sent by the EPC and the
                           first record sent by the DBS.
