14:05:29 <Steven> Steven: Well, the final report link is fine; it's only the draft links to Norm's page that is broken
14:06:12 <Steven> Norm: Let us remove the drafts link, or otherwise I'll reinstate the link

14:12:13 <Steven> Topic:  Status of implementations
14:12:28 <Steven> Norm: I have implmeneted metadata in the prolog proposal
14:12:38 <Steven> ... also the simple datatype checking proposal
14:12:55 <Steven> John: I've implemented metadata proposal too
14:13:02 <Steven> ... also a subtraction operator
14:15:15 <Steven> ... that unmatches possible matches
14:16:37 <Steven> Michael: Be interesting to think about performance aspects
14:17:36 <Steven> Steven: Definitely needs a theoretical underpinning

14:22:42 <Steven> [None]
14:23:02 <Steven> s/[None]//
14:23:22 <Steven> Michael: Gunther has added a change to some tests fror space after prolog
14:23:29 <Steven> Norm: I will merge
14:23:57 <Steven> Topic:  Review and resolution of bug reports and technical issues
14:24:19 <Steven> Subtopic:   Pull request #227 Add .gitattributes
14:24:48 <Steven> Norm: I want to skip this week
14:24:57 <cmsmcq> Depends on newline handling.
14:25:08 <Steven> Topic:  Issue #233 There are other things called iXML
14:25:13 <Steven> Closed
14:25:39 <Steven> Topic:  Issue #139 Sample grammars for IRIs and URIs
14:26:20 <Steven> Pending action
14:26:40 <Steven> Topic:  Issue #137 Document the XML tag set of ixml grammars
14:26:45 <Steven> Awaiting action
14:26:58 <Steven> Topic:  Issue #137 Document the XML tag set of ixml grammars
14:27:29 <Steven> Norm: There is a PR, and there is a small change from Michael
14:27:47 <Steven> ... [reads change]
14:27:50 <Steven> Steven: Fine
14:28:05 <Steven> Topic:  Issue #203 Spec should say nonterminals are case-sensitive
14:28:20 <Steven> Michael: Same
14:29:59 <Steven> Topic:  Issue #192 Normalizing line endings in ixml inputs
14:30:25 <Bethan> https://github.com/invisibleXML/ixml/pull/242
14:30:47 <norm> https://invisiblexml.org/pr/242/autodiff.html
14:31:54 <Steven> "Invisible XML processors normalize line endings when they read grammar and input files. They apply the same rules as [XML]: every occurrence of the two character sequence #D #A, and any #D not immediately followed by a #A, are translated into a single #A in the input. This assures that the single character #A can always be used to match an end of line, irrespective of the conventions of the system where the files were created. It follows[CUT]
14:31:54 <Steven> iXML exclusion ~[#A]* will always match all of the characters to the end of a line."
14:32:22 <Steven> John: Do we want to add something about making it an option to turn that off?
14:32:52 <Steven> Michael: I don't think it's necessary
14:33:07 <Steven> .. I'm happy with this version
14:33:16 <Steven> ... I do have one residula concern
14:33:40 <Steven> s/ula/ual/
14:34:03 <Steven> Michael: John Cowen says on Oct 24
14:34:19 <Steven> ... something
14:34:28 <Steven> Norm: We have given him what he wants
14:35:05 <Steven> Bethan: he is saying that which character we normalise to is a separate issue, and then gives some choices.
14:35:05 <cmsmcq> s/Cowen/Cowan/
14:35:35 <Steven> Norm: We need to write more tests if we adopt this.
14:36:56 <Steven> Bethan: Small point. Can we use either #A or #a consistently?
14:37:02 <Steven> Norm: I will fix
14:39:04 <Steven> Steven: I think the ixml grammar is fine, and doesn't need any change to reflect this.
14:40:15 <Steven> Norm: Closing this
14:41:39 <Steven> Topic: Issue #237 What would the absense of version number mean?
14:41:50 <Steven> s/sense/sence/
14:41:51 <norm> "In this case, it is implementation-defined which version or versions the implementation uses when it attempts to parse the grammar. "
14:42:50 <norm> https://invisiblexml.org/pr/243/autodiff.html
14:44:43 <Steven> Steven: I would like unrecognised and absent version numbers to be treated identically
14:44:55 <Steven> Norm: I will take another stab at it.
14:45:27 <Steven> Topic:  Issue #239  Support simple data types?
14:45:36 <norm> https://github.com/invisibleXML/ixml/issues/239
14:46:11 <Steven> Norm: You want a grammar for an ISO Date
14:46:34 <Steven> ... it can't limit it to exact dates, and leap years and so on
14:46:46 <Steven> ... we already have types for this
14:47:15 <Steven> ... I propose we allow XML types be used
14:47:42 <Steven> ... I did a test implementation
14:48:00 <Steven> John: I did a similar thing
14:48:11 <Steven> ... using XPath expressions
14:49:15 <Steven> .. I'm in an XPath-rich environment
14:50:33 <Steven> Steven: I'm in two minds about this
14:50:57 <Steven> ... it adds a big chunk that solves a tiny part of the computability problem
14:52:15 <Steven> Steven: Is this to identify dates or check them?
14:52:33 <Steven> Norm: For identifying. It adds to the parsing.
14:54:22 <Steven> Michael: [A question about whether it's an ORacel or ...]
14:54:58 <Steven> Norm: I have an oracle in mind. If there's a type that defines prime numbers, it would accept that.
14:55:39 <Steven> s/ORacel/Oracle/
14:55:59 <Steven> Michael: I need time to think about.
