IRIs

<johnarwe> 4632 nor P2 Linu cmsmcq@w3.org NEW Use of IRIs

Philippe reports: IRI support is not in Java 6. Need to deal with non-ASCII characters
...Issue: What happens when you pass IRI for URI?
... Original issue: Switch from URI to IRI in specification?

Discussion proceeds between Philippe and Bassam regarding size and cost of project to implement IRI.

<MSM> [For what it's worth, http://java.sun.com/j2se/1.4.2/docs/api/java/net/URI.html describes the java.net.URI class as accepting arbitrary Unicode characters and doing the percent escaping properly in the path]

<MSM> http://en.wikipedia.org/wiki/Punycode

<MSM> Wikipedia make the punycode algorithm seem reassuringly simple to implement as a string-string transform

Bassam: Is this right time for us to do this? Should it be requirement? (Future implementations would have to anticipate future Java implementations.)

<plh> http://www.ietf.org/rfc/rfc3987.txt

Bassam: Critical concern in SML is the comparison of URIs / IRIs.

Bassam is Checking current implementation of URI creation algorithm for handling non-ASCII escaped character

<johnarwe> ACTION: Philippe to Check situation in Java when creating URI whith non-ASCII character. [recorded in http://www.w3.org/2007/07/12-sml-minutes.html#action01]

<trackbot-ng> Created ACTION-105 - Check situation in Java when creating URI whith non-ASCII character. [on Philippe Le Hégaret - due 2007-07-19].

<Bassam> static void Main(string[] args)

<Bassam> {

<Bassam> Uri uriA = new Uri("http://www.??.com");

<Bassam> Uri uriB = new Uri("http://www.??.com");

<Bassam> bool doesCompare = uriA.Equals(uriB);

<Bassam> }

<Bassam> ?? non-ASCII

Bassam: .NET does seem to compare correctly.

<MSM> Here's an interesting example.

<MSM> If you use www.zürich.com

<MSM> and compare to IDN representation www.xn--zrich-kva.com

<MSM> or to punycode www.zrich.com-0ob

<MSM> or to utf-7 www.z+APw-rich.com

Bassam: If this is what is expected for support of IRI, then no addition is required.

<plh> As an example,

<plh> "http://r&#xE9;sum&#xE9;.example.org" may be considered equivalent to "http://xn--rsum-bpad.example.org".

<Bassam> static void Main(string[] args)

<Bassam> {

<Bassam> Uri uriA = new Uri("www.z�rich.com");

<Bassam> Uri uriB = new Uri("www.xn--zrich-kva.com");

<Bassam> bool doesCompare = uriA.Equals(uriB);

<Bassam> }

<Bassam> static void Main(string[] args)

<Bassam> {

<Bassam> Uri uriA = new Uri("www.z�rich.com");

<Bassam> Uri uriB = new Uri("www.xn--zrich-kva.com");

<Bassam> bool doesCompare = uriA.Equals(uriB);

<Bassam> }

<Bassam> uriA throws an "invalid URI format" exception

<Bassam> Bassam: .NETFX does NOT support IRI in the form of "www.z�rich.com" and "www.xn--zrich-kva.com".

<johnarwe> Kirk loses connection to internet, will try and reconnect

<Bassam> Bassam: such IRI throw an "invalid URI format" exception

<plh> Bassam, and if you add "http://" ?

<plh> you give a domain name to the Uri class, not a full addresss...

Definitions of consumers, producers - related to email discussion

<Jim> Part 1: What is considered an SML consumer?

<johnarwe> how much to align with TAG Note http://www.w3.org/2001/tag/doc/versioning

<ginny> I think John's definition of SML consumer as: an "SML consumer" ... is a consumer of 1/more SML documents that processes those document(s) using, in whole or part, semantics defined by SML.

<ginny> is a simple and adequate definition.

Ginny: What is point of defining "SML Consumer"?

Issue - In SML-IF there are normative requirements placed on SML consumers and producers (section 3.1)

John: If this is in SML-IF, it does not put requirements on SML.

Jim: Issue is what does it mean to understand a model?

John: XSLT processor consumes SML, but does not treat it as an SML document. It treats the document simply in terms of the XML that it "understands". See emails earlier this week too for detailed discussion.

Ginny: Agrees with John's definition, but we can't go further.

MSM: Also agrees.

General agreement (by silence) of leaving this discussion in SML-IF rather than moving it to SML spec.

Jim: Part two of the issue: Should we comment to the TAG regarding use of terminology?

John: Comment that the "simplified" diagram seems inconsistent; also, the acts of consumption and production don't imply anything about what is understood.

Jim: Feeling is that unless someone feels strongly enough "to carry the torch", let it go.
...John: WG does not feel strongly enough to carry this forward with the TAG.
