RE: [w3c sml] section "resolving an SML reference" section missing.

What exactly does the statement "References MUST be supported by model
validators that conform to this specification" (section 4) mean?

 

In the context, I would take this statement to mean that every reference
must be supported by at least two model validators.  In other words, to
use just an SML URI scheme in a reference, the URI scheme MUST
(obligatorily) be supported by at least validators "out there" in the
market place.  If there is only one URI scheme validator "out there",
then must I include another scheme for which a validator exists in order
to meet this requirement on the reference itself?  (Ok, I'm being a
little ridiculous on this last question, but it is to point out that the
statement could say something radically different than what was intended
if read literally.)

 

Is the intention to something more like:  Processing SML references
SHOULD employ a model validator that conforms to this specification - ??

Thanks Ginny for performing this extensive analysis. I think Valentina
and I reached the same conclusion when we were discussing 5291. 

I'd also like to keep the current organization. "Rules" are generally
easier to understand than "steps". 

I can also see how the steps could help people, especially implementers.
Also the steps helped us (the WG) to ensure that we got what we wanted. 

Maybe a compromise could be to keep the current organization, and
include the steps as a non-normative section? Or the other way around
(rules non-normative; steps normative), but this could be much harder to
do. 

So I can see 3 options: 
1 Rules only 
2 Both rules and steps, with steps non-normative 
3 Both rules and steps, with rules non-normative 

No strong preference.

BTW, a purely editorial comment. It seems that the organization of 4.2.1
and 4.2.2 looks a bit awkward. The current 4.2.1 and 4.2.2 overlap a
little bit; and 4.2.1 also depends on the second half of 4.2.2. Would it
help at all to have: 

4.2.1 At most one target 
4.2.2 Consistent Reference Schemes 
4.2.3 Identical Targets 

where 4.2.1 and 4.2.2 talk about different aspects of the "one target"
rule; both of them need the "identity" definition for targets, which is
defined in 4.2.3?

[w3c sml] section "resolving an SML reference" section missing.

 

 

 



As promised, attached is a document that contains the missing section in
the SML spec that I believe Kumar was referring to in our last meeting.
The document contains the missing section and also the current text for
comparison. The missing text lists several reference resolution and
model validation requirements. I've indicated in the comments which of
the current sections contain these requirements.

I prefer the current text and organization rather than the missing
section for the following reasons:

- the missing section mixes reference resolution and model validity in
what appears to be a series of 'steps'
- the current organization allows us to define terms and add additional
information along with specifying each requirement.
