For Hydra Connect 2016, the local organizers took the project's basic logo and extended it. It was used on large display screens adjacent to the conference's main auditorium.
Two or so years into the Hydra project, around 2010, an on-line demonstrator was produced for the emerging software. The product was called Hydrangea. It proved difficult to keep up to date at a time of rapid development and was soon dropped - but it was in use long enough to get its own logo.
The team that founded the Hydra Project met several times in the fall of 2008 at the University of Virginia. At their meeting in December of that year the name 'Hydra' was coined. Later that same day, a hydra toy was spotted, and subsequently purchased, in a local shop - this became part of the first design used on the project's documents and presentations.
A presentation given at Samvera Connect 2019 described thus and This presentation will cover the initial work to move the University of Michigan’s Deep Blue Documents repository from DSpace to Hyrax on Samvera and also merge it with the U-M data repository, Deep Blue Data, which is already on Hyrax. Deep Blue contains more than 120,000 items and has been around on DSpace since 2006. The Deep Blue Data repository started in 2016. Presenters will discuss steps taken so far to migrate and merge the repositories, including creating a minimum viable product (MVP) list, testing migration, addressing challenges so far, collaborating between IT and service providers, and determining next steps.
