Loads of potential, but stubsWhat can these do?How will practices be collected?

Image Overlays
Mikel Maron What's Next, GeoRSS FOSS4G 2006
Confusion of Multiple Flavors, Namespaces
W3C vs Simple vs GML
Geo “RSS”
What's the Point, GeoRSS?
Mikel Maron What's Next, GeoRSS FOSS4G 2006
How does it stay open as interest gains and implementations multiply?
How do we govern overselves when we're completely open?
How does a “community standard” stayed controlled within closed standards bodies?
- Microformats model?
An Open Standards Process
Mikel Maron What's Next, GeoRSS FOSS4G 2006
OGC White Paper & Lightweight InitiativeW3C Incubator Group
How do open standards work in membership based standards groups?
Mikel Maron What's Next, GeoRSS FOSS4G 2006
- Sensors ObsRSS- Transport Data
Can a GeoRSS-like process be applied to other heavy weight standards?
Mikel Maron What's Next, GeoRSS FOSS4G 2006
Is a Microformat serialization of GeoRSS appropriate?What is the content? hAtom is sillyHuman Readable?Reusing HTML?
Speaking of Microformats
Mikel Maron What's Next, GeoRSS FOSS4G 2006
Is there an obvious, simple, unrestricted way to open up to place names
Addresses?
Or do we resolve to another namespaceWorking under the same model?
<georss:featurename>
Toponyms
Mikel Maron What's Next, GeoRSS FOSS4G 2006
With huge spreads of GeoRSS being published (flickr, weather, for example)
what's the best way to aggregate
how to aggregate a search?
A9 OpenSearch?
Aggregation ...
Mikel Maron What's Next, GeoRSS FOSS4G 2006
bbox is enough?WFS Basic
Can we devise a standard way to query for GeoRSS?
Mikel Maron What's Next, GeoRSS FOSS4G 2006
xslt/sparql hard to process space seperated lists(unlike w3c geo)
but are these really seperate properties?Problems with commas led to GML space separated
Some processing problems
Mikel Maron What's Next, GeoRSS FOSS4G 2006
A lightweight Catalog Spec
OpenSearch(?)
Discoverability
Mikel Maron What's Next, GeoRSS FOSS4G 2006
open to loads and loads of feeds (kiva, globalvoices)but inaccurate
RSS to GeoRSS converters
Mikel Maron What's Next, GeoRSS FOSS4G 2006
Why does it need to be an open standard?What's wrong with KML?
Google and KML
