If you've used the Archives' digital collections to search for photographs or read old issues of the Barnard Bulletin, you've used an open source software called Islandora. Open source software is powered by community contributions, and in January, Archives Director Martha Tenney led collaborators at other schools that use Islandora in an online hack/doc, which combines the form of a hackathon–bringing coders together to work on a predetermined problem in a large block of time–with a substantial documentation and testing component. At the January 13-14 hack/doc, 40 participants worked on developing tools for metadata cleanup and migrating data out of the current version of Islandora.
