EXIF, Machine Tags, Groupr, and more Paul Mison

After we published Paul’s interview last week, he wrote in to let us know Groupr had been dusted off and was alive and well again. And followed it up with a post on machine tags, and automated EXIF extraction, two of our favorite topics here at Code.Flickr:

Why bother with such a thing? Flickr will extract EXIF metadata, but it won’t allow you to do any aggregate queries on it. By extracting all the data from my photos into machine tags (and a local SQLite database), it becomes possible to point people at all the photos taken at the wide end of my widest lens, or those taken with a particular make of camera (and to do more complex queries locally).Flickr, EXIF, Machine Tags
