[georss] Discovery of georss and other geographic information?

[Ron Lake]

Relative to the last point there has already been discussion on this list of
using the ebRIM Catalogue profile for the purpose stated.

 

I should note that the next release of Galdos WFS will support harvesting
and we consider this a potential common feature with Catalogue.

 

Cheers

Stefan -

 

I browsed the wiki sites mentioned in your email. A couple of
questions/observations:

 

1. I believe that WFS 1.1 supports both GML 2.1.2 and GML 3.1.1 (see
outputFormat) and by restriction, the new GML simple features profile. The
new GML app schema is only 61 pages long with 20 pages of examples.

2. I was wondering why OAI-PMH page compares OAI-PMH with WFS? WFS is not
designed for harvesting or for being a Catalogue service. WFS is designed so
that once a content resource has been discovered (and perhaps registered in
a Catalogue/Registry) that source can then be queried and asked to return a
set of features (as a GML payload).

3. Was wondering if the new OGC Catalogue 2.0.1 19119/19115 Application
Profile has been looked at.? Seems to me that there could be some real
synergy between this Cat App Profile and OAI-PMH.
https://portal.opengeospatial.org/files/?artifact_id=8305 . There are
already quite a few implementations of this Application Profile.

 

Cheers


Carl

Raj,

 

I agree that encodings can differ as long there is a common understanding on
the semantic level and as long 'best encoding practices' are fulfilled (what
currently is the case in GeoRSS).

 

But newly published encodings should consider established ones, which seems
to not the case actually (in W3C draft?). I know that standardization is
slow but programmers often don't care...

 

But my initial question was not only targeted to adjust GeoRSS to be
accepted as a Microformat. What I'm thinking about currently is
(auto-)discovery of geodata and services as documented here
http://www.gis.hsr.ch/wiki/OSGeodata_Discovery .

 

I'd like to discuss if GeoRSS icons are means to guide webcrawlers to
xml-encoded content or if there is a need for a 'friend' attribute in a (yet
to be re-defined ISO 19115) metadata as described in
http://www.openarchives.org/OAI/2.0/guidelines-static-repository.htm

2006/9/4, Raj Singh <raj at rajsingh.org>: 

If you have a hammmer, everything looks like a nail.

I say that because the hammer many people on this list have is information 
architecture. We try hard to make everything elegant in the information
model. I think interoperability occurs best at the programmer level, and
therefore we shouldn't try to hard to make all encodings of geography 
interoperable from an encoding standpoint. If it takes less time for
programmers to code with less elegant encodings, then that's the "right" way
to do it.

This is a long way to say that I agree that GeoRSS should stop with support 
for Atom and some other RSSes. If it's simpler to diverge from this encoding
to do microformats and/or XHTML, so be it.

My 2 cents,
Raj
