11、for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has t
12、he right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft I
13、nternational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO11788 was prepared by Technical Committee ISO/TC23, Trac
14、tors and machinery for agriculture and forestry, Subcommittee SC19, Agricultural electronics. ISO11788 consists of the following parts, under the general title Electronic data interchange between information systems in agriculture Agricultural data element dictionary: Part 1: General description; Pa
15、rt 2: Dairy farming; Part 3: Pig farming; Part 4: Poultry farming; Part 5: Non-animal stationary application. Annex A forms an integral part of this part of ISO11788. Annex B and Annex C are for information only.iv blankBSISO11788-1:1997 BSI 04-1999 1 Introduction Standalone computers on the farm re
16、quire that data must be manually entered and collected from the different computers. This is a laborious task which becomes superfluous when the computers are interconnected and able to communicate with each other automatically to share and exchange information. Information exchange means data trans
17、port between the management computer on one side and each process computer on the other side. An agricultural data element dictionary (ADED) consists of data elements that may be used in the agricultural sector to exchange data electronically. ADED is closely linked to agricultural data interchange
18、syntax (ADIS), which is a syntax used in the agricultural sector to exchange data electronically. ADED in combination with ADIS makes electronic data interchange possible. In a data element dictionary all data elements are described in a unique way. Each element is uniquely identified by a data dict
19、ionary number (DD number). Data dictionaries for data exchange between management computers and process computers may be subsets of larger data dictionaries. The standardization of on-farm data interchange between management computer and stationary process computers consists of an ADIS and an ADED.
20、ADIS is described in ISO11787. A general description of ADED is given in this part of ISO11788, the other part of ISO11788 describe data dictionaries for different fields of application. This part of ISO11788 describes the general structure of an agricultural data element dictionary; lists the attri
21、butes of data elements and entities; gives the header structure (an entity that is used in all data interchanges, independent of the field of application). NOTEThe term “process computer” can also be read as “datalogger”. 1 Scope The data elements described in ISO11788 are intended for communication
22、 between on-farm process computers and management computers. This part of ISO11788 specifies how an agricultural data element dictionary (ADED) may be used for on-farm data exchange. The data elements concerning mobile equipment are not dealt with in this part of ISO11788. ADED data elements may be
23、used for: direct data exchange between process computer and management program; data exchange between process computer and interface software of the process computer on the management computer (PC) (alternatively, manufacturer-specific methods may be used for this exchange); data exchange between th
24、e interface software for the process computer on the PC and the management program. NOTEThis does not mean that agricultural data elements cannot be used for other data interchange. Many farmers use a method similar to ADIS to exchange data between management computers and external computers. ADED m
