Missing fn prefix on count function in 14.5 Hidden Groups example
by Mike Beckerle 12 Oct '17

12 Oct '17

The example shows an expression "{ count(.... ) }". This should be fn:count with the prefix. It would be very odd to bind the default namespace to the XPath function namespace for these tiny expressions. I can imagine someone doing that if they have a large expression, but in this example we should be more explicit.

propose new dfdl:binaryNumberRep "offsetBinary"
by Mike Beckerle 15 Sep '17

15 Sep '17

We have found a number of places that use offset-binary numeric representation. This is also called excess-K, or biased, but I think offset binary is a better description of it. In this representation you take an unsigned binary, and just subtract an offset. E.g., for a 3-bit number, mostSignificantBitFirst: bits unsigned twos-comp offsetBinary 000 0 0 -4 001 1 1 -3 010 2 2 -2 011 3 3 -1 100 4 -4 0 101 5 -3 1 110 6 -2 2 111 7 -1 3 At the moment, users have to work around this in Daffodil using inputValueCalc and outputValueCalc. This is feasible, but really awkward for such a simple concept. So we suggest that the next revision of DFDL include dfdl:binaryNumberRep="offsetBinary" Thoughts? ...mikeb Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com Please note: Contributions to the DFDL Workgroup's email discussions are subject to the OGF Intellectual Property Policy <http://www.ogf.org/About/abt_policies.php>

We are pleased to announce the release of Daffodil 2.0.0! Downloads are available as zip, tar, and rpm at: https://opensource.ncsa.illinois.edu/projects/artifacts.php?key=DFDL&versio… Daffodil is the open source implementation of the Open Grid Forum's Data Format Description Language (DFDL) specification. http://www.ogf.org/dfdl Daffodil uses DFDL descriptions to parse data into an XML or JSON infoset for ingestion and validation. Daffodil can also perform the reverse, by serializing or "unparsing" an infoset back to the original data format. Daffodil 2.0.0 is a monumental milestone that denotes stability and usability, and is ready for general availability. Major features that make up this release include: - Support for unparse with one-to-one feature parity with parse - New API with native support for JDOM, w3c DOM, Scala XML, XML text, and JSON - Support for many non-byte size encodings - Support for xs:choice direct dispatch - Support for xs:boolean types - Support for xs:ignoreCase="yes" - Support for xs:union restrictions - Many improvements to the DFDL expression language - Numerous bug fixes and performance improvements More details of the changes are available: https://opensource.ncsa.illinois.edu/confluence/display/DFDL/Changelog https://opensource.ncsa.illinois.edu/jira/secure/ReleaseNote.jspa?projectId… Daffodil 2.0.0 has also been integrated into Apache NiFi and XML Calabash, with the source available in the following git repositories: Apache NiFi: https://opensource.ncsa.illinois.edu/bitbucket/projects/DFDL/repos/daffodil… XML Calabash: https://opensource.ncsa.illinois.edu/bitbucket/projects/DFDL/repos/daffodil… Although Daffodil has reached this milestone, active development continues, with some features not yet available.
