 The Role of Architectural Forms in XML-EDI
Link to this resource This paper suggests how some of the Architectural Form Definition Requirements expressed in Annex A-SGML Extended Facilities of ISO/IEC 10744-1997 could be used to simplify the creation and management of XML document type definitions (DTDs) that are designed to be used for business-to-business electronic data interchange (EDI).  | This paper presents the SGML Architectural Form as an alternative mechanism for XML document semantics. The advantage which it offers it that AF's are a technique which can be immediately realised using current XML standards and tools. However, the disadvantage is that AF's provide only a labelling mechanism that can be used to map specific kinds of elements to specific processing semantics. True schemas declare the explicit data semantics and constraints, whereas AF's declare conformance to a semantics which is hidden in a processing module. However, it may well be (as the author states) that AF's provide a short-term solution for instance documents of well-understood schema. |  |
