IBM DFDL error messages
by Steve Hanson 31 Oct '13

31 Oct '13

IBM is sharing the error messages that it issues for schema definition errors in order to assist other DFDL implementations. Attached are the IBM DFDL model component and validator component error messages. Between them they should cover all SDEs, except those caused by violation of XML 1.0 and base XML Schema 1.0 rules - we just echo what we get back from the EMF code. Notice that the messages all have a consistent structure for the text. However considerable rationalisation is possible if one combines error messages that are essentially the same and use appropriate inserts. If the DFDL WG agrees that is the right thing to do then IBM can do this and re-distribute.

FYI. -Jonathan -----Original Message----- From: datascience-list-bounces(a)nist.gov [mailto:datascience-list-bounces@nist.gov] On Behalf Of Greenberg, Craig S Sent: Thursday, October 24, 2013 8:57 AM To: datascience-list Cc: datascience Subject: [Datascience-list] NIST Data Science Symposium RESCHEDULED to March 4-5, 2014 Dear Data Science Community, The NIST Data Science Symposium has been rescheduled to March 4-5, 2014. The difficult decision to reschedule the event is due to several unforeseen circumstances. We hope that you will be available to participate in the rescheduled symposium, and we are deeply sorry for any inconvenience this may cause. Abstracts that have been submitted will still be considered, and updated versions as well as new submissions will be welcome. For those who already registered to attend the symposium, your registration will remain active. If you need to withdraw your submitted abstract or cancel your registration, please send an email to datascience(a)nist.gov. More information will be made available in the near future. In the meantime, please feel free to send any questions you have to datascience(a)nist.gov.

action 224: add section for implementation defined limits
by Cranford, Jonathan W. 24 Oct '13

24 Oct '13

All, Action item 224 was raised two weeks ago during the WG call. 224 Add section for implementation defined limits (All) 3/9: Several places in the spec cite this, should be grouped. Currently partially listed in section 2.6. Also note distinction between 'implementation defined' and 'implementation dependent'. Check spec for correct usage. Resolve during public comment. The action item was created based on a comment I made during the call, so I thought it'd be good to provide an example of the distinction I was trying to make. The W3C XProc specification does a great job of differentiating between implementation-defined and implementation-dependent features, with a convenient list of each in the appendix. Appendix A (http://www.w3.org/TR/xproc/#conformance) contains the following text. Conformant processors must implement all of the features described in this specification except those that are explicitly identified as optional. Some aspects of processor behavior are not completely specified; those features are either implementation-dependent<http://www.w3.org/TR/xproc/#dt-implementation-dependent> or implementation-defined<http://www.w3.org/TR/xproc/#dt-implementation-defined>. [Definition: An implementation-dependent feature is one where the implementation has discretion in how it is performed. Implementations are not required to document or explain how implementation-dependent<http://www.w3.org/TR/xproc/#dt-implementation-dependent> features are performed.] [Definition: An implementation-defined feature is one where the implementation has discretion in how it is performed. Conformant implementations must document how implementation-defined<http://www.w3.org/TR/xproc/#dt-implementation-defined> features are performed.] Section A.1 then lists all the implementation-defined features, and section A.2 lists all the implementation-dependent features. I think the XProc spec provides a great example to follow on two counts. First, it formally distinguishes between implementation-defined and implementation-dependent features. The choice of terms isn't nearly as important as the distinction itself, of course: implementations must document how certain features are implemented. In the DFDL realm, section 2.6 lists some implementation limits which always constitute schema definition errors; surely these are the types of details that must be documented by any DFDL implementation. Using terminology such as "implementation-defined" and "implementation-dependent" would flag these types of documentation requirements for implementations within the specification. Second, all the implementation-defined and implementation-dependent features are listed in one place in the specification. I think doing the same in the DFDL spec would provide a great resource for DFDL implementers. Comments? If everyone agrees, I don't mind taking the action to search through the document looking for candidates for inclusion in such a list. Sincerely, -- Jonathan W. Cranford Senior Information Systems Engineer The MITRE Corporation (http://www.mitre.org)
