[DAS2] Notes from the weekly DAS/2 teleconference, 19 Jun 2006

I have a temporary CGI set up to accept WRITEBACK documents:
I have attached a das2xml document that POSTs cleanly for me using the
lwp-request that is part of libwww-perl. Please modify this document, post,
and let me know if anything breaks.
This implementation accepts only new records. It supports neither updates
nor deletes. Furthermore, it only accepts new feature records. It does not
support new type records, new region records, or any other type of record.
Feature records may have 0 or more locations, 0 or more parents, 0 or more
children, and 0 or more properties. All parts/parents must be present in
the document (no refering to existing features by URI), or it will throw a
HTTP 500 error.
Next I will implement the update and delete support. This should be fairly
straightforward, and may be doable over the weekend.
