Crowdsourcing platform for full text transcription and tagging
Concordia is a platform for crowdsourcing transcription and tagging of text in digitized images. It was developed by the Library of Congress so that volunteers of all backgrounds could transcribe and tag digitized images of manuscripts and typed materials from the Library’s collections that could not otherwise be done by optical character recognition.
This is attempt to make an open source bookmarking system that supports tagging, distributed data storage, genetic "splicing" of strains of bookmarking tags and much more!
