Finding a research data article repository archive

Whether you're looking for data to reuse or integrate with your research, or trying to find somewhere to deposit your own data, a relevant data repository (also known as an archive or data centre) is a good place to start.

Discipline-specific repositories

The best place to start is a repository that focuses specifically on the types of data you work with. There are thousands of these available, but you can easily browse by subject area in the Registry of Research Data Repositories (re3data) to find something suitable.

General-purpose repositories

If there isn't a suitable specialised repository, we recommend trying one or more of the following more general options:

Zenodo 

example:
https://zenodo.org/record/375921
An open access data, software and publication repository for researchers who want to share multidisciplinary research results not available in other repositories. It was developed by and is hosted at CERN, but is suitable for all types of research data. It is free to use and has guaranteed funding from the EU for the foreseeable future.

dryad

only datasets
Dryad is built upon the open-source DSpace repository software. All customizations not available within the main DSpace distribution are available from the Dryad code repository under an open source (new BSD) license.
Dryad supports multiple ways of receiving article or manuscript metadata from publishers. The simplest method involves reading email notifications, but we are also implementing a REST API for those desiring greater control over the data deposition process.

datahub Open Knowledge Foundation

https://datahub.io/
CKAN is a tool for managing and publishing collections of data. It is used by national and local governments, research institutions, and other organisations which collect a lot of data. With its powerful search and faceting, users can browse and find the data they need, and preview it using maps, graphs and tables - whether they are developers, journalists, researchers, NGOs, citizens or your own colleagues.

CKAN is free, open-source software, which has been developed by the Open Knowledge Foundation since 2006 and used by government and organisations around the world. Version 2.0 was released in May 2013.
