This is a visualization of the curation of TEI XML documents in the Shelley-Godwin Archive's sg-data Git repository github.com/umd-mith/sg-data. It highlights how a distributed group of scholars collaborated to create the TEI documents that make up the archive. It also demonstrates the activity that a version control system like Git records, and its application in a digital curation environment.
The two green clusters of nodes that appear in the top left corner about 10 seconds after the video begins are the TEI XML documents. You should be able to make out different users who are making edits to them. The other portions of the visualization are Word documents and code related to the archive.
The sg-data repository is where the Shelley-Godwin TEI XML documents were started. If you are looking for the current data it has since been moved to a new repository: github.com/umd-mith/sga/tree/master/data
