Re: RDDL draft 20010114

["Thomas B. Passin" <tpassin@home.com>]

I just went through an interesting little test of the draft.  I tried to
validate it using rxp.  I copied the draft to my computer, and then the dtd.
That didn't work - of course -  since the dtd's address is relative, and rxp
couldn't find all the included fragments.  Then I added the rddl base url to
the path in the DOCTYPE declaration so it read
"http://www.openhealth.org/RDDL/rddl-xhtml.dtd".  Now rxp could find the
pieces.

rxp said the document is well-formed and it gave no validity errors - of
course it gave a lot of warnings about redefinitions - but it also had
warnings about missing attributes.  It didn't like the xlink or rddl namespace
"attributes", and it didn't seem to understand the html stuff.  This part of
the warning messages is included below.

There are several interesting things here.

1) I either needed to edit the html file, or I needed a catalog mechanism to
find the rddl dtd - in other words, I need rddl-aware software  to validate
the rddl spec if I import it to my own machine!  Intriguing.  This leads to
the next point.

2) Once the spec is complete and valid, it would be very nice to use it as
part of any conformance requirements.  In other words, a conforming
(validating) processor has to be able to validate a local copy of the spec,
since it describes its own dtd!  You might have to tweak the rddl element for
the dtd by adding an arcrole so that the processor can be sure what the dtd is
for.

3) Although rxp is reasonably fast, the validation process was pretty slow.
The slowness seems to have been getting all the dtd pieces over the network.
This highlights how important caching is going to be.  In turn, this says that
rddl will have to work with cached resources.

I'm not really up on caching issues.  Anyone who is, please help out here.
What, if anything, needs to be included in rddl to have it work correctly with
cached resources?

Here are some of rxp's earnings:
