Path expressions for EDI based on a proposal in ISO/TS 20625:2002

["Moberg Dale" <dmoberg@axway.com>]

ISO/TS 20625:2002 describes the rules for the derivation of XML schemas from EDI MIGs providing a sound method of representing semantic facts.

ISO/TS 20625:2002 describes how to derive XML from UN/EDIFACT MIGs. In principle, the rules are equally applicable to other EDI standards.

 

Here is a naming convention

 

 

6 Rules for the generation of XML schemas derived from EDI MIGs

6.1 Rule 1: Tag naming

6.1.1 Variant 1

The names of the XML structure will be derived from the EDI tags.

They will be given a prefix depending on the structure level (segment

group, segment, composite data element or data element):

„M_“+ message type + [suffix] Example: M_ORDERS

„G_“+ segment group + [suffix] Example: G_SG36 or G_LIN_ALC

„S_“+ segment + [suffix] Example: S_LIN

„C_“+ composite data element + [suffix] Example: C_C082_2

„D_“+ data element + [suffix] Example: D_3035 or D_3035_10

The suffix is optional and can be generated based upon various

semantic understanding of EDI elements.
