- Inter-University Consortium for Political and Social Research (http://www.icpsr.umich.edu/) ICPSR is the world's largest archive of social science data, and has been collecting, curating, and delivering content for nearly fifty years. Our historical approach has been to normalize file formats into plain ASCII (for survey data) and plain ASCII or TIFF images (for data documention), and to store the content in the filesystem and the metadata in a relational database. More recently we have been normalizing our metadata into the DDI XML standard (http://ddi-alliance.org). 
; We are just getting started with Fedora and are tackling an initial project of moving our oldest content into Fedora 3.x. Due to the lack of good administrative metadata from those early days, this makes for a project that is both very easy (e.g., the content model is simple) and very challenging. I've been posting some initial thoughts on an approach in my ICPSR blog (http://techaticpsr.blogspot.com).
