I was introduced to the concept of ethnoclassification over the weekend, and so was pleased to run across this ethnoclassification primer (via MANE IT News): Metadata for the masses. From what I understand, ethnoclassifcation refers to metadata tags that arise from the data (actually, are imposed by those who create the data) rather than tags that are imposed from above. Del.icio.us (ex. CCTE Distributed Research) and Flickr (ex. my photos) are the two sites that are being pointed to as employing this method, and from the sounds of it, we’ll be seeing more soon.
