Release 0.81

This release contains only a parser. There is no unparser functionality in this release.

The following are not yet implemented as of this release:

  • Numeric Types: decimal, integer, nonNegativeInteger

  • textNumberPattern
  • Other Types: boolean, hexBinary, and all associated properties.

  • For types date/time/dateTime binary representations (text representation IS supported)
  • nilKind="literalCharacter"

  • nilKind="logicalValue"
  • useNilAsDefault
  • lengthKind="endOfParent"
  • lengthKind="prefixed"
  • occursCountKind="stopValue"
  • Defaulting of values for required elements
  • separatorSuppressionPolicy
  • ignoreCase="yes"
  • the newVariableInstance annotation element
  • textNumberKind="zoned"
  • any 'packed' binary number representation (packed, bcd, ...)
  • unicodeByteOrderMark
  • bi-directional text properties
  • unordered sequences
  • documentFinalTerminatorCanBeMissing
  • external variables
  • choices: choiceLength property
  • raw-byte entities
  • validation - to be clear, one can call the dfdl:checkConstraints function from an assertion or discriminator or inputValueCalc, but there is no command-line option to tell Daffodil to validate the data with respect to the schema.
  • utf16Width='variable'
  • save/reload of a parser
  • alignment, alignmentUnits, leadingSkip, trailingSkip
  • dfdl:contentLength and dfdl:valueLength functions
  • attributeFormDefault (attribute of the xs:schema element)
  • the 'type' component of the DFDL Infoset

Some additional limitations:

  • File sizes are limited to 4Gigabytes due to underlying Java libraries using type int for offsets.
  • A Java 7 JVM is required as a number of its regular expression capabilities are passed through to Daffodil's DFDL implementation (as is required by the standard).
  • An expression enclosed in {{ ... } cannot have whitespace before or after the brace {{, } characters. To work around this limitation, use CDATA, that is, as the body of an element, wrap expressions like this: <![CDATA[{...expression...}]]>

There is a list of bugs available in our JIRA tracking system.
