Subject: Re: [entity-resolution-comment] Some queries on the XML Catalogsspec
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 / Richard Tobin <richard@cogsci.ed.ac.uk> was heard to say: | (You certainly make it hard to post comments here! The address in the | spec is wrong - is has an "s" on the end of comment - and you can't | subscribe in the way it describes.) Fixed. | I'm implementing the XML Catalogs spec for RXP, working from the 21 | Feb 2003 draft, and I have a few queries: Cool! | Is the system identifier input to the resolver the system identifier | as it appears in the document, or the result of absolutizing that? | Presumably the latter, but it doesn't seem to say that in section 7.1. It's the former, as Paul said. I don't see any obvious way to say that in the spec, though. The resolver uses whatever you hand it. | Step 3 of 7.1.2 does not mention that the rewriteSystem entry with the | longest systemIdStartString is the only one used. This is stated in | 6.5.5, but it should be explicit in the description of the algorithm. Fixed. | Section 6.3 does not explicitly say whether the hex digits in a | %-escape inserted during normalization must be in upper or lower case, | though the use of %HH might be taken to mean upper case. Since there | is no mention of these being matched case-insensitively, it is | important which are used. I recall some discussion recently that suggested U/C was the more widely accepted choice, so I've added that. | Is there a recommended way to handle external identifiers when parsing | catalog files themselves? Obviously they cannot be looked up in the | catalog. Is it reasonable to have a copy of catalog.dtd built-in to | the parser and special-case its system and public identifiers? This is a *really* good point and one that I stumbled over just recently myself. (Lauren, I'd like to discuss this at the next meeting.) Richard, what do you think the right answer is?
