LODr is a new semantic web application that allows you to convert your web 2.0 tags from various sites like Flickr to semantically enriched web 3.0 URIs. For example, say you took a photo of a place in Southampton, uploaded it to your Flickr account and gave it a tag “southampton”. LODr lets you connect the tag “southampton” to a URI on the semantic web that represents the entity Southampton. In this case I chose to link up to the Southampton represented in the Ordnance Survey administrative geography ontology. Other tags can be linked to URIs in DBpedia, geonames or if music is your thing the new BBC music beta (semantic) web pages.
I guess initially this will appeal mainly to semantic web geeks, but it will be interesting to see what sort of mash-ups this generates as more and more tags are connected to URIs.
