[georss] Getting started with Georss & KML

[Holmes, Charles V.]

Thanks for all the responses.  The sample feed and schemas will be
immensely useful.  

FeatureServer is very interesting too since part of the project will be
converting OpenLayers features from the EditingToolbar into KML too.
However, it just doesn't seem to follow the approach of where we're
going.  One question I did have though...when I click the KML button
(http://featureserver.org/demo.html), the result in Google Earth
contains 100's of features rather than those just shown on the map.
Where are these coming from?

I will take your advice about the loose approach.  The design we're
going with is taking gml and w3c formats and converting them to the
spec, so, internally, we only have a spec feed.  But I'm beginning to
feel that we'll need to convert gml, simple and w3c to spec simple.

One other question.  Georss doesn't support altitude.  I'm sure there
are some small number of people who have altitude information they want
to encode (e.g. location of world's highest peaks).  How do they handle
such a case?  Do they use another format, or does another coordinate
system in gml support altitude?

Thanks,
Charles

Mapufacture is back up - so you can use it for converting feeds/KML or
grabbing some more examples. I've also put up a "full" example on the
front-page of georss.org

This is a very good point. There is a big difference between being
"compliant" with the 'spec' and actually being able to consume the
large number of feeds out there that are broken in some way. This is a
general problem with RSS and user-created documents in general.

It's also why people like Google, Mapufacture, and I assume
FeatureServer don't want to be thought of as the "Validators". Too
often people think "but it works in GoogleMaps - I must have it
right". Gregor pointed out FeedValidator, and hopefully peopl start
using that more now that it supports GeoRSS & KML.

Perhaps all of our aggregators should ping (via SMS, phone calls,
knocks on the door in the middle of the night) feed owners whenever we
see their feed is invalid (but still loosely parse it)
