[georss] RE: Drafty timeline for GeoRSS

Wed May 3 18:42:13 EDT 2006

All -

Below is a draft timeline for the current instance of GeoRSS. I have checked with several folks but know I have missed key dates, may not have correct info, or am missing key elements.

Please check over and let me know of any additions, deletions, etc.

I apologize in advance for any ommisions. Timelines are good so that we can capture info now and update as we go so that there is not confusion in the future.

Regards

Carl

1997 - Dave Winer "plays around" with web feeds.

1998: RFC 2445 - iCalander, released as an Internet standard. Has a simple 
location syntax for a point geometry. This is relevant because it appears 
that the W3C geo syntax is based on the one in iCalander.

1999 RSS "invented" - Netscape RSS v 0.9 released

2001: Internet draft submitted to the IETF Geo-registration (geotagging) of 
HTML documents, Kaegi and Daviel. Never became a standard but significant 
because it appears to build on the iCalander systax but is much richer and 
more semantically rigorous.

2001 February: Yahoo geowanking discussion list. Minor discussion on how to 
link an RSS message to a geographic location.

2002: GeoURL concept established - geotagging of URL locations. 
www.geourl.com

2002 July: RDFMap (Chris Goad): First known instance of geoenabling an RSS 
document.  http://www.mapbureau.com/rdfmap0.91/index.html . Interestnig to 
note that the developers also checked out GML 2.x, used the geometry model 
but modified the syntax so that it would work with RDF.

2003 January: First version of the W3C "geo" vocabulary/syntax published. 
geo is a simple microformat (RDF based) for geotagging web content using a 
point geometry

2003 May. First known instance of the use of the term "georss". In an email 
in the geowanking discussion list.

2003 July: Harvard releases RSS 2.0

2004 Summer: geowanking discussion list on the concept of a geourl molecule 
code. This would be a microformat for tagging content.

2004 Raj presented a paper on GeoBlogging in the summer of 2004 at URISA's 
Public Particiation and GIS conference in which he mentions the georss 
concept: 
http://web.mit.edu/rajsingh/www/cmp/collabmaps/Singh-GeoBlogging.pdf.

2004 During the summer of 2004, Raj, Josh, Allan, and others discussed 
geoenabling feeds during the Boston area GIS Interest Group meeting.

2005 February: At Location Intelligence, Carl had a meeting with Dave Sonnen 
in which we discussed light-weight geospatial payloads and standards related 
work being done in the IETF.

2005 April: George, Ron, and Carl write a draft GML Point Profile.

2005 March: At the BAAMA Symposium, Carl had dinner with Mike Leibold and we 
discussed the concept of geo-enabling (or geotagging) light weight payloads 
as part of Web 2.0 and the geospatial web, including web feeds.

2005 July. Raj, Josh, and Allan decided to go for georss.
Raj Singh registers the georss.org domain on 7/20/2005. This could be 
considered the official start date of the current georss initiative.
Allan Doyle sets up the georss server on an eogeo machine over the next 
couple of days.

2005 Summer: Raj Singh stands up georss.mit.edu feeds application.

2005 July: The IETF releases ATOM 1.0 as an internet standard.

2005 August: Then in August 7th and 8th, Raj and Carl had an email exchange 
on ATOM and how we might have missed the boat in terms of providing input to 
geo-enable ATOM. This led me to have a dialogue with Tim Bray (major enabler 
for the  development of the ATOM spec) geoenabling ATOM.

2005 August: All this led to an August 18th teleconference - and I am not 
sure who actually who suggested this - to have a brainstorming session that 
included Allan D, Josh L, Raj, Ron Lake, and Carl R.. There were actually a 
series of teleconferences and emails. Some of the teleconferences pre-dated 
the dialogue with Tim Bray.

At this point, many others began contributing to the discussion, setting 
requirements and so forth.

2006 January - What we believe to be the first official version ready for 
implementation.

2006 March: Mikel Maron stands up first georss feed validator.

2006 March: GeoRSS goes to ROME (http://georss.geonames.org/)

2006 April: GeoRSS Blog is set up.
