A preliminary version of a DFDL Schema for MIL-STD-2045 is now available on the github DFDL Schemas site.

This schema makes use of the dfdl:bitOrder='leastSignificantBitFirst' property and the x-dfdl-us-ascii-7-bit-packed character set encoding that are being added to DFDL v1.0 in response to a public comment review.

These features have been prototyped in the Daffodil open-source DFDL implementation; hence, this DFDL schema will (as of this writing) only run with that DFDL implementation. This schema is, in effect, the proof point that the new DFDL features will in fact address the needs that were raised by the public comment on bit ordering.

This data format has much in common with other binary MIL-STD data formats, so techniques illustrated in it are expected to be used in other DFDL schemas. However, as of this news item some improved ways of modeling the data have already been discovered, so this DFDL schema for MIL-STD-2045 is expected to evolve substantially.

The schema is available at https://github.com/DFDLSchemas/mil-std-2045

The repository in DFDLSchemas GitHub which contains DFDL schemas for the Toshiba Commerce (formerly IBM) 4690 Transaction Log (Tlog) point-of-sale format has been updated.

It now includes schemas for SuperMarket Application (SA) in addition to the existing ACE schemas.

The schemas are compatible with IBM DFDL 1.0 and 1.1 releases, as shipped in IBM WebSphere Message Broker 8.0.0.2 onwards and IBM Integration Bus 9.0.0.1 onwards, respectively.

Example data streams and XML infosets are included.

Full details in the repository readme at https://github.com/DFDLSchemas/IBM4690-TLOG.

The repository in DFDLSchemas GitHub which contains DFDL schemas for the ISO 8583 standard has been updated.

It now includes schemas for 1993 and 1987 versions of the standard, supporting both packed bitmaps and unpacked bitmaps.

The schemas are compatible with IBM DFDL 1.0 and 1.1 releases, as shipped in IBM WebSphere Message Broker 8.0.0.2 onwards and IBM Integration Bus 9.0.0.1 onwards, respectively.

Example data streams and XML infosets are included.

A new repository has been added to the DFDLSchemas GitHub website which contains DFDL schemas for the UN/EDIFACT standard.

The initial schemas in the repository model a selection of supply chain messages from the D03B release, namely DESADV, INVOIC, ORDCHG, ORDERS, ORDRSP, RECADV and REMADV. Other messages and releases are available from IBM.

The schemas are compatible with IBM DFDL 1.0 and 1.1 releases, as shipped in IBM WebSphere Message Broker 8.0.0.2 onwards and IBM Integration Bus 9.0.0.1 onwards, respectively.

The schemas include the following features:

• Full UN/EDIFACT interchange;
• Dynamically defined delimiters via UNA segment;
• Syntax version 4 and syntax version 3 (minor edit required);
• Segments with or without new lines at the end;
• Interactive messages via UIH/UIT segments;
• AUTACK, CONTRL and KEYMAN service messages;
• Separate schemas for each industry/release combination, in their own namespace.

Our public DFDL schemas web community is now live. The first DFDL schemas are up there, others will follow. Anybody can download and use the schemas subject to accompanying license. Anybody can apply to the DFDL WG to create a repository for a new format, or to contribute to an existing repository.
