This is a post about our first release of Orbital.
About a month ago, Dr. Tom Duckett, Reader in The Department of Computing and Informatics approached the Orbital project because he urgently wanted to publish around 20GB of data for Long-term mobile robot operations. That afternoon, we gave Tom and Feras Dayoub, his Research Assistant, space on one of our servers and they uploaded a bunch of HTML pages and the zipped up data. We minted a proxy URL for them and advised them on an appropriate data license to choose. We also set up Google Analytics, so they could see what interest in his data there was.
Job done. For the time being.
What Tom really wanted was to be able to email a link to his data to a robotics mailing list and tell an international community of likeminded researchers and manufacturers that the data was available to use. He says that long-term datasets for mobile robots are quite rare in his community, so there was a good chance people would be interested in them. He also wanted to be able to demonstrate his work when writing an EU bid. There will be a follow up blog post about what impact this has had on Tom’s research.
That afternoon got us thinking: What is the minimal set of functions that a researcher like Tom requires of a Research Data Management tool?
Tom wanted access (sign in) to a server (hosting) where he could upload his data (storage) and describe it so that other people could understand and download it (publish) under an appropriate license. The URL pointing to the data should be persistent, even if the data itself is migrated from one system to another. The impact (analytics) of the data should also be measurable.
Tom’s chance intervention in our project made us focus on Orbital v0.1 as the ‘minimum viable product‘ for researchers who need to publish open data. We thought his requirements were a great opportunity to release something early and start getting direct user feedback on our product. We decided to set a release date for Orbital v0.1 a month ahead and aim to deliver everything that Tom asked of us in this first release.
A Minimum Viable Product has just those features that allow the product to be deployed, and no more.
Today, we released Orbital v0.1 and it does everything described above. It’s an alpha release, but we’ve been testing it like crazy, we also had Feras test it and we’ve been pushing code through Jenkins since the beginning of the project so we know it passes our QA checks and we think it’s stable enough for use. From this point forward, Orbital and the URIs it mints will persist, too.
From today, a researcher at the University of Lincoln can sign in to Orbital, create and describe a project, upload their data to the project, choose a license for the data and add a Google Analytics code to measure project analytics (we’re also tracking each button click to better understand how people use Orbital). The data is published at a id.lincoln.ac.uk URI, which will persist indefinitely. At this stage, until we’ve got an approved business case for scaling it up and out to all academics, we’ll be limiting uploads on a case-by-case basis. You can view and request what other features we develop for Orbital on UserVoice, or in more detail on our project tracker. We’ve also written a basic development roadmap.
For developers, here are the basic technical details. You might also want to trawl through our implementation plan and the collected blog posts at the bottom of the plan.
Orbital is written in PHP using the CodeIgniter development framework. It’s split into two main pieces of functionality. Orbital Core (database and APIs) is currently hosted on a Linux box on Rackspace’s cloud. Orbital Manager (the User Interface) is likewise hosted on Rackspace. A user signs in to Orbital Manager via OAuth 2.0 using their university credentials. Orbital Manager is using Twitter’s Bootstrap framework. The project metadata is stored in a MySQL database. Files are uploaded to Rackspace’s cloud files storage using Andrew Valums’s AJAX Uploader. APIs are exposed using Phil Sturgeon’s CodeIgniter REST server.
Orbital is licensed under the GNU Affero GPL 3 license and you can download, fork it and create pull requests on Github:
New contributors to Orbital will be ritually applauded each weekday morning 🙂 Thanks.
