My second Linux Journal article, titled Geotagging Web Pages and RSS Feeds was posted yesterday.
It was a little difficult to narrow down the current, commonly used geotagging mechanisms. I'm very excited about the results of the SWAD-E results of their Workshop on representing geographic information in the semantic Web. Doing things like FOAF (friend of a friend) relationships with geographic information. Having tooltips that popup showing relative geographic distances between links (e.g. this link is located 4.5km away).
Let me know your thoughts on the article.
