still no need for fn:error
by Mike Beckerle 03 Aug '16

03 Aug '16

Here's the example as suggested by Jonathan of how to issue an error that I previously was suggesting needed fn:error. I'm convinced this is sufficient and we can avoid the need for fn:error now. <xs:element name="magic_number" type="ex:uint32" dfdl:byteOrder="bigEndian"> <xs:annotation> <xs:appinfo source="*http://www.ogf.org/dfdl/*<http://www.ogf.org/dfdl/dfdl-1.0/> "> <dfdl:assert test="{ (xs:unsignedInt(.) eq *dfdl:hUInt('0xa1b2c3d4')*) | (xs:unsignedInt(.) eq *dfdl:hUInt('0xd4c3b2a1')*) }" message="{ fn:concat( 'Magic number ', dfdl:hexBinary(dfdl:unsignedInt(.)), ' was not 0xA1B2C3D4 (for bigEndian) or 0xD4C3B2A1 (for littleEndian).' }" /> <dfdl:setVariable ref="ex:bOrd">{ xs:unsignedInt(.) }<dfdl:setVariable> </xs:appinfo> </xs:annotation> </xs:element> -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com

Dear Steve/Mike, we eventually discussed with our contractor the points raised last summer on the use of DFDL schema included in S2G tool (and now in our underlying parser DLDL4S. The disposition we agreed is recorded for information in the attached pdf. It relates to one of the point of latest minutes.

action 228 - tutorials - small progress
by Mike Beckerle 16 Feb '16

16 Feb '16

Progress on this action. Here's a start at a tutorial on bit-order. Eventually the URL will change to a more reasonable and stable one: https://opensource.ncsa.illinois.edu/bamboo/artifact/DFDL-MASTER21/JOB1/bui… <https://exchange10.columbia.tresys.com/owa/redir.aspx?C=518bb2929d6b4d75a8f…> This is the TDML source file corresponding to it where you can see the <tdml:tutorial> elements have been inserted with extensive xhtml5 markup. https://opensource.ncsa.illinois.edu/bitbucket/projects/DFDL/repos/daffodil… This renders well in Chrome and in Firefox. Have not tried other browsers. We have a background project here (meaning people are squeezing it between other things) at Tresys to add interaction capabilities to these, where one would have buttons that take you to an interaction dialog where you can edit the schema and/or expected/input data and run. The links above do not have any connections to this feature yet. So the advantage of TDML in the above is only that the files are sure to create verifiable working examples that do not become stale and non-working.

clarification: textStandardDecimalSeparator
by Mike Beckerle 11 Feb '16

11 Feb '16

Is textStandardDecimalSeparator really supposed to be a List of string literals, or just a single string literal. ICU only supports a single one. Not sure if this is a mistake. Right now Daffodil just does Schema Definition Error if there is more than one string literal.

minor spec fix - bitOrder description
by Mike Beckerle 09 Feb '16

09 Feb '16

Description of the bitOrder property says: "The bit order can only change on byte boundaries, and alignment of up to 7 bits will be inserted to ensure byte-alignment whenever the bit order changes." Should say "The bit order can only change on byte boundaries, and alignment of up to 7 bits will be skipped (parsing) or inserted (unparsing) to ensure byte-alignment whenever the bit order changes.
