punting on beta9

[Peter McCartney]

Heres my status:

spatialReference - finished content revisions, ca 3 more hours of work to do
on documentiation, probably can check that in Monday.

protocol - done pending some more feedback regarding my last bug entry, but
can check in now if cvs will let me.

spatialImage, Grid, Vector
	- Huge frustrations here - there are major difference between the
december draft of 19115 and the 19115.3 draft of ISO, mostly in a downward
direction. Despite the work I had put into these files, I have to admit that
between the lack of constistency and support in ISO, the recent memo from
NSF regarding the possibility that federal mandates for FGDC compliance may
apply to NSF funded projects, and ESRI's tool support for FGDC, I'm inclined
to replace these modules with equivalents based on FGDC and GML (GML
provides a true ontology for geometry types compared to the worthless
enumerations in both FGDC and ISO). Given the relative simplicity of the
Vector and Grid models, i think i can get these done by Wednesday. We may
have to wait on an image module - ISO 19115.3 completely dropped all the
remote sensing related stuff so im not sure what's going on there now. ill
give you a better idea on monday.

view, storedProcedure. We didnt really talk much about these - they just
need documentation and i can circulate them for review on monday. - im a bit
vague as to how to link attributes and constraint to these modules. we need
to be able to tell someone that a view can be joined with another entity, so
unless someone has an objection, im assuming that constraint can apply to
these entities as well. 

I think we should shoot for starting the discussion on packaging soon - even
before we've finished the individual module revisions. we still dont know
what bugs this is going to turn up.

Hey,

There are a number of modules that have not yet been finished, so we are 
going to have to wait on the release of beta9.  I propose we shoot for 
the end of next week to package the release.  Can everyone be done their 
modules by say Wednesday?

I'm making headway on the packaging changes and have been discussing at 
leat 5 alternative technologies for satisfying our requirements while 
simplifying our system.  We are leaning towards ID/IDREF from XML, or 
key/keyref from XML Schema, or XLink.  They all have some fatal flaw 
with regards to our goals, and their similarities are deep, so the 
choice may be somewhat arbitrary.  This packaging/linking issue is also 
tightly bound to the "distribution" element in resource, and what it 
means to have an external link.  I'll try to send an email Monday that 
outlines a proposed approach.  Sorry for the delay -- its been confusing 
work.

These packaging changes, as well as copyright and namespace changes, 
will need to be layered on top of all of the other module changes that 
you are making, so it would be good if you could try to wrap up your 
module changes by the middle of next week.

Thanks for all of the work!
Matt
