This goes out to all the @champions and anyone working on data repositories.
If you have put down a data repository, whether an OAR clone, or otherwise, I would like to urge you to suggest the data repository to the Registry of Research Data Repositories (Re3data). This is a service run by DataCite, to make data findable. To include your repository, just fill in the form at http://www.re3data.org/suggest
One of the things we've tried to promote in the Sci-GaIA project is making data FAIR :
See https://www.force11.org/group/fairgroup/fairprinciples for more details on these principles.
FAIR is just a set of principles currently - there is a working group trying to address means for making FAIR data a reality, via consultation.
Feel free to have a look there to see if you can contribute ideas and work on the issues at hand.
