dfdl:calendarLanguage - should allow an expression?
by Steve Hanson 29 May '13

29 May '13

DFDL has the design point that the combination of schema & data should give the same result regardless of locale and/or machine. To create a schema that does vary across locale or machine requires the user deliberately to use expressions for the relevant DFDL properties (encoding, decimal separator, etc) and parameterise the schema, using either built-in DFDL variables or user-defined variables. However the dfdl:calendarLanguage property is only defined as a String, I think it should also allow an expression as otherwise a schema is tied to a particular locale for it's calendar language support.

examples of decimal validation using pattern facet
by Mike Beckerle 24 May '13

24 May '13

Roger costello of Mitre provides this example of using pattern facet. Basically, it expresses several different possible formats, all of which are some combination of digits and a optional decimal point. In terms of cobol-style patterns it is one of these formats: 99 99.9 99.99 99.999 99.9999 I am not sure a textNumberPattern can handle the optionality of the decimal point. I know we can deal with the varying number of fraction digits, and the fixed number of integer digits, but conditional decimal point I am unsure about. ---------- Forwarded message ---------- From: Costello, Roger L. <costello(a)mitre.org> Date: Fri, May 17, 2013 at 4:00 PM Subject: RE: examples of decimal validation using pattern facet To: Mike Beckerle <mbeckerle.dfdl(a)gmail.com> Cc: "Cranford, Jonathan W." <jcranford(a)mitre.org> Hello Mike,**** ** ** **Ø **Can you send an example of the lat/lon validation **** **Ø **you mentioned on yesterday's Daffodil call?**** ** ** Here ya go:**** <xsd:simpleType name="foo"> <xsd:restriction base="xsd:decimal">**** <xsd:minInclusive value="00"/> <xsd:maxInclusive value="59.9999"/> <xsd:pattern value= "[0-9]{2}|[0-9]{2}\.[0-9]{1}|[0-9]{2}\.[0-9]{2}|[0-9]{2}\.[0-9]{3}|[0-9]{2}\.[0-9]{4}" /> </xsd:restriction> </xsd:simpleType>**** ** ** /Roger**** ** ** *From:* Mike Beckerle [mailto:mbeckerle.dfdl@gmail.com] *Sent:* Thursday, May 16, 2013 8:15 AM *To:* Costello, Roger L. *Subject:* examples of decimal validation using pattern facet**** ** ** Roger, Can you send an example of the lat/lon validation you mentioned on yesterday's Daffodil call? The other members of the workgroup are wondering what can't be done via totalDigits/fractionDigits, etc. The rationale for why pattern facet is not supported on numbers in DFDL is that we already have a much more powerful mechanism for parsing and unparsing numbers called textNumberPattern. The pattern facet only allows pass/fail using a regex, and is considered redundant (and problematic) for numbers as a result. ...mike -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com**** -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com

rationale for only allowing pattern facet on xs:string type
by Mike Beckerle 16 May '13

16 May '13

The pattern facet is allowed on all types in XML Schema. DFDL says the XSDL pattern facet is for xs:string type elements only. What is the rationale for this restriction? We are encountering many constraints in format specs that are using XML Schema regular expressions, where those regex are applied to numeric types (e.g., xs:decimal for lattitude and longitude). -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com
