Following the change of name from the Hydra Project to Samvera, the Steering Group commissioned a set of logo designs for the community. Of those submitted, the tree, in autumn colors, was the clear favorite. This logo went into use mid-2017. The Samvera logo is a registered trade mark in the USA and is the subject of trademark applications in Canada, the UK and the EU.
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 Hydra logo that was the branding for the Hydra Project throughout most of its existence under that name. It was dropped when the Community changed name to Samvera in order to avoid a trademark dispute.
Following a number of successful trademark applications, "TM" was added to the basic Samvera logo. The Samvera logo is a registered trade mark in the USA and is the subject of trademark applications in Canada, the UK and the EU.
