Title: Message
Daniel,
Do you
think that we have to add more examples and explanations to the UDDI V3
Specification, Appendix D.2 Multiple names in the same
language?

SAP,
whether it's written in Latin or non-Latin alphabet, remains meaningless with
respect to the language in which it's written and therefore what's significant
is the script - and not the language - qualifier.
This
issue touches upon the intended use of content in UDDI registries.
Content intended for developers has different representation requirements than
content intended for marketing or legal use; there may conceivably
be other contexts too. For instance, legal name of OASIS is SGML Open,
but it's doing business as OASIS. Also, SAP and IBM stand for various
things (some more obscure than others <g>), which may or may not be
specified in their complete form depending on intended
context.
Is
this something worth addressing in the spec?

Claus,
I agree with all what you say, but I have just
one small remark:
1. Select the encoding for this message as
UTF-8
2. Read this
СÐÐ
This how Russians call SAP. It sounds the same,
but they use their alphabet. I suspect that Chinese, Japanese and other
non-Latin alphabets have their own
transcriptions/interpretations.
Cheers,
Max

use="optional" on the description element
There was a lengthy discussion about requiring
the xml:lang attribute for names during V3 development and the V3 authors
consciously decided to specify it as being optional. Names like "SAP"
simply don't have an associated language. See section 3.3.2.3 of the V3
specification for more details. Also, using statically defined or
out-of-band negotiated default values can invalidate digital
signatures.
A different thing are descriptions. I tend to
agree that descriptive text always has an associated language and believe
that the V3 authors also wanted to specify this. Interestingly, the V3
specification (section 3.3.2.4) and the V3 API schema are in sync and BOTH
specify the xml:lang attribute as being optional for descriptions. This is
true since not specifying the use attribute for attribute declarations (as
is done for xml:lang within the description element) results in an
optional attribute (see XML Schema specification at http://www.w3.org/TR/xmlschema-1/#cAttribute_Declarations).
In case we were trying to make xml:lang
mandatory within descriptions, we would have a problem for migrating data
from V2 to V3 (xml:lang is also optional in V2). Which language should be
applied to those descriptions that don't carry an xml:lang value? Maybe
this was the reason why xml:lang is still specified as being optional in
V3.
Regards,
Claus

I do not see how we can have a default value without providing a
way for the client to find out what it is. A publisher may have a
different idea of what the default value is than the inquirer, which
means that an out-of-band implied agreement must exist between all users
of a registry. A node, on the other hand, is not involved in the
interpretation of content (is it?), so it is not a party to such
agreement. A node may be used though to establish the agreement
between users by publishing a special "default language" descriptor in
the node businessEntity. It could be either in the
businessEntity's categoryBag or down at the service level to allow for
multiple different default languages on multiple services or endpoints,
if that's a realistic requirement. Sounds like TN
material?
Replication also complicates things
somewhat...
My opinion is that it would be
worthwhile to make xml:lang mandatory everywhere.
This would eliminate the need for users to agree on a default. If
the registry is used by more than one language community, it would be
very difficult to establish and meaningfully enforce a default
language.

Omission of use="optional" on the description

My reading of the standard suggested that it was
optional, and that its omission indicated that the text was in the
"default" language, not that the idea of default language is
adequately described - is it default for the node, or default for the
user?
It used to be that only one entry could use any given xml:lang
value (including default), but that restriction has been eased in V3.
As I see it, any number of entries could be coded to the default, so
optional seems a valid way of indicating this.
I'd be in favour of drawing it into line with the treatment of
xml:lang for names - the two are analogous, as I see it.

Yes, the xml:lang is optional everywhere else but
for descriptions. I
agree we weren't consistent in its
treatment. I also seem to recall that
it was
intentionally left as required here because descriptions
are
intended to be human readable text and having the xml:lang
can be important
for such uses. We should consider if
this line of reasoning is important
before making it optional I
think.
Other opinions? Someone with a different
recollection than mine here?
Thanks,

[uddi-spec] Omission of use="optional" on the
description
element
Tom / TC,
Please note that
the http://uddi.org/schema/uddi_v3.xsd
schema omits
use="optional" on the description element. I think
this is an omission and
recommend we correct this
definition as part of CR-002. The current schema
is
declared
as:
<xsd:elementname="description"type="uddi:description"final="restriction"/>
<xsd:complexTypename="description"final="restriction">
<xsd:simpleContent>
<xsd:extensionbase="uddi:validationTypeString255">
<xsd:attributeref="xml:lang"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
... when I think we should have it
declared
as:
<xsd:elementname="description"type="uddi:description"final="restriction"/>
<xsd:complexTypename="description"final="restriction">
<xsd:simpleContent>
<xsd:extensionbase="uddi:validationTypeString255">
<xsd:attributeref="xml:lang"use="optional"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
For your
consideration.
