character string used as an abbreviated means of
recording or identifying information. (b) To represent or identify information using a specific symbolic form that can be recognised by a computer. |
| Component data element | A simple data element which is a subordinate portion of a composite data element and in an interchange is identified by its position within the composite data element. |

| Data element | A unit of data for which the identification, description and value representation have been specified. |
| Data element name | One or more words in a natural language identifying a data element concept. |
| Data element separator | A character used to separate data elements in a segment. |
| Data element tag | A unique identifier for a data element in a data element directory. |
| Data element value | The specific entry of an identified data element represented as specified in a data element directory. |
| Data element representation | The format (e.g. numeric, alphabetic, variable length etc.) of a data item. |
| Detail section | The portion of the message between the header and the detail section which relates to detail information only. |
| EDIFACT | Electronic Data Interchange for Administration, Commerce and Transport. |
| Explicit representation | The technique used to give an absolute identification of the location of a data segment within a message. |
| Functional group | One or more messages of the same type headed by a functional group header service segment and ending with a functional group trailer service segment |
| Functional group header | The service segment heading [and identifying the functional group. |
| Functional group trailer | The service segment ending a functional group. |
| Group of segments | Identified, usually repeatable, grouping of related segments. |
| Header section | The portion of the message which precedes the actual body and trailer of the business transaction, and which contains information which relates to the entire message. |
| Identifier | A character or group of characters used to identify or name an item of data and possibly to indicate certain properties of that data. |
| Interchange | Communication between partners in the form of a structured set of messages and service segments starting with an interchange control header and ending with an interchange control trailer. |
| Interchange agreement | Document, usually in the form of a user manual, which describes, e.g., level of syntax, messages, legal and security requirements, etc. |
| Level | Relative hierarchical position of a data segment within a message. |
| Mandatory | A statement in a segment or message directory which specifies that a segment, a data element, a composite data element or a component data element must be used. |
| Message | A set of segments in the order specified in a message directory starting with the message header and ending with the message trailer. |
| Message structure diagram | A graphic representation of the sequence of segments within a message. |
| Message header | The service segment starting and uniquely identifying a message. |
| Message trailer | The service segment ending a message. |
| Message type | An identified and structured set of data elements covering the requirements for a specified type of transaction, e.g. invoice. |
| Nested segment | A segment which directly relates to another segment in an identified and structured group of segments covering the requirements for a specific message type. |
| Omission | Exclusion in an actual message of one or more units of data which are defined as conditional in a message type specification. |
| Qualified data element | A data element whose precise meaning is conveyed by an associated qualifier. |
| Qualifier | A data element whose value shall be expressed as a code that gives specific meaning to the function of another data element or a segment. |
| Release character | A character used to restore to its original meaning any character used as a syntactical separator. |
| Repeating segment | A segment which may repeat in a message as specified in the relevant message type specification. |
| Section control segment | A service segment used to separate header, detail and summary sections of a message where necessary to avoid ambiguities in the message segment content. |
| Segment | A predefined and identified set of functionally related data elements values which are identified by their sequential positions within the set. A segment starts with a segment tag and ends with a segment terminator. It can be a service segment or a user data segment. |
| Segment code | A code which uniquely identifies each segment as specified in a segment directory. |
| Segment directory | A listing of identified, named, described and specified segments. |
| Segment name | One or more words in a natural language identifying a data segment concept. |
| Segment table | A table showing the sequential order of segments, their arrangements in segment groups and the status and allowed repetitions of the segments and groups in a message. |
| Segment tag | A composite data element in which the first component data element contains a code which uniquely identifies a segment as specified in the relevant segment directory. Additional component data elements can be conditionally used to indicate the hierarchical level and nesting relation in a message and the incidence of repetition of the segment. |
| Segment terminator | A syntax character indicating the end of a segment. |
| Separator character | A character used for syntactical separation of data. |
| Service data element | A data element used in service segments. |
| Service segment | A segment required to service the interchange of user data. |
| Service string advice | A character string at the beginning of an interchange defining syntactically delimiting characters and indicators used in the interchange. |
| Simple data element | A data element containing a single value. |
| Status | Specifies whether an element or segment is mandatory or conditional. |
| Summary section | The portion of the message which follows the body of the message and which contains summary information relating to the entire message. |
| Syntax rules | Rules governing the structure of an interchange and its functional groups, messages, segments and data elements. |
| Tag | A unique identifier for a segment or data element. |
| Trading partners | The sending
and/or receiving parties involved in exchanging
electronic business messages. |
| UNSM | United
Nations Standard Message, an EDIFACT message type
approved for international use. A UNSM is a message
which: I. has been registered, published and which is maintained by the United Nations Economic Commission for Europe; II. has the values contained in the Controlling Agency, Message Type, Message Version Number and Message Release Number fields (the requirements for the use of which are specified in ISO 9735), allocated and controlled by the UN/ECE; III. always has the code value "UN" in the Controlling Agency field. |
| UNSM Sub-set | A sub-set of
a UNSM is a message which is directly derived from an
approved UNSM, has the same function as the UNSM from
which it is derived, and which: I. contains all of the groups and segments defined as having a mandatory status within the message, and the mandatory data elements within them. There shall be no change to the status, order or content of the groups, segments and composite data elements and data elements contained within the segments. (It should be noted, however, that although many UNSMs contain Conditional Groups of segments which may contain one or more mandatory segments, providing the complete conditional group is omitted from the sub-set, this does not break the rule regarding the inclusion of mandatory segments); II. does not change the status, order or content of the Segments, composite data elements and data elements in the conditional segments chosen for use from the UNSM. III. does not add any segments, composite data elements or data elements to the message; IV. contains the identical values specified for use in the Message Type, Controlling Agency, Message Version Number and Message Release Number fields, as are specified for the UNSM from which the sub-set is derived. |
| User data segment | A segment which, in contrary to a service segment, contains the information itself. |
