[DAS2] will miss today's conf. call

[Andrew Dalke]

Hi all,

   Not only am I on the road back from the Python conference but
my cell phone battery is nearing dead so I won't be able to make
it to today's phone conference call.

   Here's my status.  I've been working on the validator, to
the detriment of the next spec rewrite.

   This validator does single-document checks.  That is, it
does not do internal integrity checks to make sure that
the results of, say, a range query only returns features in
that range, or that the features are in the range given by
the segments.

   I plugged the results into a web server running on my
laptop.  It's using some new Python libraries which are
not yet installed on the OBF machine, but which I can install
after I get back to Santa Fe.  The GUI is similar to what
I threw together at Sanger during the Sprint - enter a URL
and a document type, view the results.

   What took long is the code to pin down where the errors
happened, for example, to show which attribute was the
extra attribute in an element.

  I've attached sample output for your viewing pleasure.

There is enough there for a Javascript jockey to make an
neat little interactive viewer, eg, click on the error
message to be shown where it occurs in the document.
Also, the marker I'm using to show where the error occurs
in the body of the text needs work - the method I use
isn't that cross platform portable.

I think the next steps for me are:
   - get the validator working as-is on the OBF web site
       (should be on-line by tomorrow)
   - get back to writing the 3rd draft of the spec.
