Net.Leksi.Edifact

The Net.Leksi.Edifact library is designed to convert messages from the EDIFACT format to XML and vice versa. The library also contains a number of utilities for creating a working environment.

All classes are contained in the Net.Leksi.Edifact namespace.

Contents of the library

The following functionality is available.

• EdifactDownloaderCLI: preparation of a command line application for downloading specifications from the site UNECE with converting them into a set of XML schemas, which are subsequently used as a grammar, and to check data and structure restrictions for the translator between formats.
• EdifactMessageCustomizerCLI: preparation of a command line application for editing the specification of a standard message (customization) for the needs of an agreed exchange between specific parties. This includes reducing the set of segments used and changing data restrictions.
• EdifactMessageVisualizerCLI: template command line application for visualizing the specification of a standard or abbreviated message in the form of a tree of segments and groups of segments.
• EdifactParser: translation of the incoming flow of the exchange session (interchange) into events:
  • start of the session;
  • beginning of the functional group (if any);
  • the beginning of the message, the handler must provide a stream for writing the XML document received from the message;
  • end of message;
  • end of the functional group (if any);
  • end of the session.
• EdifactBuilder: broadcasting calls of the corresponding methods to the specified outgoing stream of the exchange session:
  • start of the session;
  • beginning of the functional group (if any);
  • message transmission, the sender provides a stream to read the XML document for translation into the message;
  • end of the functional group (if any);
  • end of the session.
• EdifactParserCLI: template command line application for translating the exchange file into XML files.

In addition to the library, the working environment includes a directory of XML schemas containing schemas obtained from downloaded specifications, as well as custom schemas. More details...

Customization is carried out using a script, which is an XML schema of a special structure. More...

The structure of XML documents is described Here.

Header classes

These are types that correspond to the EDIFACT header and trailer system types.

• BatchInterchangeHeader - batch session header, corresponds to the UNB segment.
• BatchMessageHeader - header reportedpacket session, corresponds to the UNH segment.
• GroupHeader - functional group header, corresponds to the UNG segment.
• InteractiveInterchangeHeader - interactive session header, corresponds to the UIB segment.
• InteractiveMessageHeader - message header of the interactive session, corresponds to the UIH segment.

Header Property Classes
