Flickr unveiled a new organization feature that seems neat. Flickr Sets let you group photos arbitrarily, based on some central idea that makes sense to owner of the photos. Sometimes Flickr users will want to create hierarchy among their Sets, and prior to the launch of today’s feature, there was really no way to create hierarchy. To address the need for nested Sets, Flickr has introduced Collections. To complement the introduction of Collections, Flickr now also allows Pro users to change their default layout.
To test out this new feature, I used my trip to Asia in 2006. On the trip I visited three countries: Hong Kong, China and Vietnam. I had attempted to create a Set for each city, then add those Sets to a Set that grouped an entire country, then add the Sets that grouped countries into one large set titled “Asia Trip 2006.” One advantage to that approach was the Guest Pass feature, which lets me invite non-Flickr users to view private photos contained in a Set. With Collections I can still do that, I just now have the additional option of nesting Sets into Collections.
Collections can contain either Sets or other Collections. So to create hierarchy using the example of my trip to Asia, I removed the Sets for each Country and the Set for the entire trip, and replaced that Set with a Collection titled Asia Trip 2006 that contains other Collections (which are Collections of Sets by country). Within the country Collections, the original Sets are there (where I can control privacy at the Set level). Now users can drill down into the Set they care about. This also obsoletes Smugmug galleries in my opinion, since Flickr now does hierarchy too, but has the advantage of allowing users to place one photo in multiple sets (without uploading them twice).
The new Layout feature lets Pro users show different default photos pages, where previously the only option a layout with the standard small size photos, a vertical bar on the right side showing Sets. Now users can remove Sets from their default page, show Collections, or various combinations of those options.
There are some negative aspects I see right away: there is no slideshow at the Collection level. There is no Group Pass at the Collection level. I’m not sure why Flickr implemented Collections to support Collections or Sets, to me it would be more useful to mix and match Sets and Collections within a Collection. As of this writing the Flickr API documentation does not include Collection information. Specifying collection_id instead of set_id to create an embedded slideshow did not work. Minor issue: the algorithm that selects random images for the mosaic is not very good, since I noticed the same image in the mosaic several times after “randomizing” it, it does not seem to pull from all the Sets in a Collection equally. Regarding comments: comments are allowed on individual photos and Sets, but initially have not been implemented for Collections.
