NOTE Existing closed systems are used subject to bilateral agreement between the participants. 3.2 open system application in which independent parties may freely participate and in which bilateral agreements are not necessary 3.3 application standard specification defining the method by which and conditions under which automatic identification and data capture technology may be applied to a particular purpose, prescribing, for example, data formats, optical requirements and symbology related parameters as subsets of the total range defined by relevant technical standards 4 Requirements 4.1 Closed or open system The developer of a standard shall determine if the system to which the application standard applies is a closed or an open system. 4.2 Pre-existing standards Before commencing the making of a new application standard, careful consideration should be given to the potential of adopting an existing standard.
Many currently used application standards are readily adaptable to specific industry uses whilst remaining totally compatible with their existing uses.
Broadening the scope of existing international, multi industry standards, provides for the ready trading of bar code marked items internationally and between industry sectors and is, therefore, the preferred option.
It should be noted that the proliferation of standards is a waste of resources and is contrary to the principles of standardisation.
4.3 Data to be encoded 4.3.1 Type of Data to be Encoded The choice of symbology will be influenced by the type of data to be encoded; which can be: —
numeric —
alphanumeric —
ASCII other character sets which, particularly in high capacity two dimensional symbologies, may be accessed by the use of the AIM : ECI — Part 1.
Annex A includes details of those symbologies which support this standard. The character set required to encode the data content shall be a subset of the encodable character set of the symbology. There are symbologies covered by European and International Standards, the encodable character set of which meet all these requirements. For a given application, the character set used may be a limited part of the total character set available. NOTE The character sets encodable by symbologies covered by European or International Standards are described in annex A. 4.3.2 Data string length 4.3.2.1 Linear symbols The data string length to be encoded will influence the length of linear bar code symbols.
The specification of long data strings, and the resultant long symbols, may be the cause of symbols being difficult to scan with a high degree of reliability and ease. It will also limit the choice of bar code printing and reading systems which may be used for a particular application. In particular some types of bar code readers may have limitations in the data string length which may be decoded and transmitted to the host system. 4.3.2.2 Two dimensional symbols For some applications the data string length to be encoded may exceed that which can be encoded in a linear symbol. In such cases high capacity two dimensional multi-row bar code or matrix symbols can be used. In their largest sizes these may permit up to two thousand characters of data to be encode in a symbol. Some two dimensional symbologies permit the decoded data from more than one symbol to be concatenated into a single data string, thus enabling very large amounts of data to be encoded in a set of symbols. 4.3.3 Data check characters For applications where key entry is used, or where data security is critical, data check characters as distinct from symbol check characters should be used. The system of data check characters used will depend upon the application, a suitable algorithm may be selected from those described in ISO/IEC 7064. SIST EN 1649:2005
