Open Repositories 2015 DEVELOPER TRACK

June 8-11, 2015, Indianapolis, Indiana, http://www.or2015.net

*** Deadline 13th March 2015 ***

Cool Tools, Daring Demos and Fab Features

The OR2015 developer track presents an opportunity to share the latest developments across the technical community. We will be running informal sessions of presentations and demonstrations showcasing community expertise and progress:

What cool development tools, frameworks, languages and technologies could you not get on without?

Is there a particular technique or process that you find apt for solving particular day-to-day repository problems?  Demonstrate it to the community.  Extra credit for command-line shenanigans and live debugging.

What new features (however small) have you added to your organisation’s repository?  What technologies were used and how did you arrive at your solution?

Presentations will be flexibly timed (5 to 20 minutes). Live demos, code repositories, ssh, hacking and audience participation are encouraged.

Submissions should take the form of a title and short paragraph detailing what will be shared with the community (including the specific platform and/or technologies you will be showcasing). Please also give an estimate of the duration of your demonstration.

Submit your proposal here: https://www.conftool.com/or2015/ by March 13, 2015

Ideas Challenge

The Developer Challenge this year has been replaced by the more inclusive IDEAS CHALLENGE. We would like to encourage teams to form before and during the conference to propose an innovative solution to a real-world problem that repository users currently face.  Each team should include members from both the developer and user community, and represent more than one institution.

Teams’ ideas will be presented to the conference and prizes will be awarded based on the nature of the problem, the quality of the solution and the make-up of the team. Find out more at www.or2105.net/ideaschallenge

For inquiries, please contact the Developer Track Co-Chairs, Adam Field and Claire Knowles  at af05[AT]ecs.soton.ac.uk and claire.knowles[AT]ed.ac.uk

Announcing Hydra 9.0.0

We’re pleased to announce the release of Hydra 9.0.0.  This Hydra gem brings together a set of compatible gems for working with Fedora 4. Amongst others it bundles Hydra-head 9.0.1 and Active-Fedora 9.0.0.  In addition to working with Fedora 4, Hydra 9 includes many improvements and bug fixes. Especially notable is the ability to add RDF properties on repository objects themselves (no need for datastreams) and large-file streaming support.

The new gem represents almost a year of effort – our thanks to all those who made it happen!
