hello planetrdf
I’ve finally updated and customised Wordpress, tweaked the links to use RSS1, and discovered that I can get category-specific feeds, eg. technology.
Planet RDF is now taking that category feed (thanks Dave!), which allows me to vent freely on other things without worrying too much about cluttering up a predominantly tech-oriented site. That said, I find [...]

Flickr’d photos via Yahoo! Maps (geo-extended RSS 2.0)
As a contrast to the GML/KML and Google-related posts, here is an annotated Yahoo! map, derrived from geo-extended RSS 2.0 markup. I tried feeding the service a variant of RSS 1.0 last week (albeit with the Yahoo! extensions implicitly in the RSS namespace) and it seemed to work. They don’t yet have worldwide coverage, [...]
Syndicating EXIF location info, nearly
I’ve been trying to get lat/long GPS data embedded in my photos, before I upload them to Flickr, so that geobloggers.com will make use of the data. So far, I can only get that site to use explicit “geo:lat=123.345″ based flickr-tagging; embedded EXIF seems ignored. See ongoing discussion in the Flickr GeoTagging group.

Profiling GML for RSS/Atom, RDF and Web developers
I spent some time yesterday talking with Ron Lake about GML, RDF, RSS and other acronyms. GML was originally an RDF application, and various RDFisms can still be seen in the design. I learned a fair bit about GML, and about its extensibility and profiling mechanisms.
We discussed some possibilities for sharing data between GML, RSS/Atom [...]

Chris Goad on RDF and GML
RDF versus GML, Chris Goad (Sept 2004),
GML is the XML language for geography developed by the Open GIS consortium. The third major revision of this specification, known as GML3, was released in January of 2003. RDFMap, when used in conjuction with RDFGeom, constitutes an attempt to develop an alternative approach based on RDF to [...]

geobloggers: “Network Link” in Google Earth
This is the hidden gem of Google Earth. Adding a “Network Link” allows you to fetch KML data from remote servers. It does this in two ways, Time Based or Location Based. So *anyone* can add dynamic data to Google Maps.
Apparently KML is based on GML. I don’t know Keyhole/Google’s work differs. There seems to [...]
