Re: [DFDL-WG] Fw: Inconsistent naming for text bidi properties
by Steve Hanson 10 Jan '12

10 Jan '12

Agreed on WG call to take errata so that second occurrence of 'text' in a bidi property name is removed. That leaves: - textBidiOrdering - textBidiOrientation - textBidiSymmetric - textBidiShaped - textBidiNumeralShape Regards Steve Hanson Architect, Data Format Description Language (DFDL) Co-Chair, OGF DFDL Working Group IBM SWG, Hursley, UK smh(a)uk.ibm.com tel:+44-1962-815848 From: Steve Hanson/UK/IBM To: dfdl-wg(a)ogf.org Date: 09/01/2012 14:44 Subject: Fw: Inconsistent naming for text bidi properties To be discussed on this week's DFDL WG call.

If textBidi is 'yes' then the following properties come in to play: - textBidiTextOrdering - textBidiOrientation - textBidiSymmetric - textBidiTextShaped - textBidiNumeralShape Two of the properties have 'text' appearing twice in the name. This seems superfluous to me. Any reason why these two properties have an extra 'text' ? I only noticed this because the IBM DFDL model has coded 'textBidiTextOrientation' which does not match the spec.

spec clarification needed: is dfdl:terminator='{ ...returns empty string ... }' allowed?
by Mike Beckerle 10 Jan '12

10 Jan '12

Let's use the example of terminator as a delimiter. If I provide an expression so that I can compute terminator at runtime, is it allowed to return empty string? I.e., equivalent to writing dfdl:terminator="" which is effectively "turning off" use of terminator? It seems very problematic to me if we allow this. Nor do I think this generality is needed. We should clarify that for initiator/terminator/separator, if a runtime expression is used, then it must return at least one non-zero-length value. So using a runtime expression for a delimiter is effectively saying "yes there will be a delimiter", you are just not binding its specific value. I believe this runtime expression capability for delimiters was intended to allow the choice of the specific delimiter to be made based on data containing the value. This is common practice in data formats. However, turning on/off whether delimiters are present or not, is not something I anticipated, and it has far bigger implications for the format. I mean you really can't decide much about the data format statically if even the existence of delimiters as part of the format or not can be postponed to runtime.
