Metadata adds value: Photos plus metadata equals money.
“Established [picture] libraries are now busy cataloguing and digitising their huge collections, and searching can be a nightmare. That's where fotoLibra has a great advantage. The people cataloguing its images are the ones who know them best—the photographers and picture owners themselves. That means picture buyers can find exactly what they're looking for, quickly and reliably.“
So here is value from Metadata being created at source. There is however an interesting forum debate about the resulting problems of “keywording”. People often overdo the metadata and “throw the dictionary or thesaurus at it” I also found it interesting that they are using DOIs.
Flickr from Ludicorp research is another photo sharing site that is getting a lot of attention and was featured in the Guardian recently. It is interesting that you can choose to license the photos you upload to Flickr under a Creative Commons license. They too place a lot of emphasis on metadata or “tags” Both these sites, because they are about sharing are good examples of Folksonomy in action. I noticed Ludicorp’s president Stewart Butterfield is sharing a platform to speak on “Folksonomy, or How I Learned to Stop Worrying and Love the Mess” at next month’s emerging technology conference in San Diego.
