At CDN, we are fostering Open Science and Open Data through a series of recommendations. We follow the Charter of Good Practices for Open Sciences, adopted by the Observatoire de Paris, in September 2018. The main points of this charter are:
The application of these principles to the ORN is declined in several ways, beyond the principles stated above, which fully apply, for example, to the publications of research teams using the instruments of the ORN. Our goal is to provide FAIR (Findable, Accessible, Interoperable and Reusable) and science ready products to the scientific community.
The scientific publications making use or related to any instruments of the ORN, shall be deposited in an open archive, such as ArXiv or HAL. We recommend to use HAL, including the “USN” tag (old name of the ORN), so that the publications can be easily retrieved from: https://cnrs.hal.science/USN.
Datasets collected with instruments of the ORN, derived from such original datasets, or that have been processed using the ORN data and computing facility, shall also be published in open repositories. We recommend to publish the datasets in the following repositories:
Software developed in the frame of projects related to the ORN shall be published with an open license, and shared in an open software repository. For ObsParis personnels, we recommend to use the institution’s GitLab server, but using other open software forges is also acceptable (such as, e.g., GitHub). A big advantage of using github is to be able to publish your code to Zenodo.
We recommend to add codemeta metadata to your repository, so that the software publication is facilitated (through software heritage, for instance)
According to French law, all resources (data, documentation, software, etc) produced by a public administration (such as research labs) must be published with an open license. The official legal license is the Etalab-2.0 open license, however, it is possible to share data under Creative-Commons-Attribution (CC-BY) license (which is very close to the Etalab Open License).
For sharing software, several options are available, depending on the licenses of the pieces of code that are reused.
Each instrument team or user at CDN shall have a Data Management Plan in place. This is a working and evolving document, which is used as an interface between the team or user and the CDN management team. The document defines what data are produced, their life cycle, their location, their accessibility and distribution channels, as well as the responsibilities of each parties. The DMP is thus a tool for the teams or users (improving their data management), as well as for the CDN team (improving the service, with accurate prediction of needs).
An inventory of the data collections related to ORN’s activity is compiled and updated regularly. This concerns both the digital collections hosted on the site’s servers, but also the old collections of data on analogue media (film, tape…) and also collections hosted in other institutes or data centres. The listed collections will enter into a virtuous process of openness that will lead to better scientific visibility and facilitate their reuse. Following the guidelines presented in this page will help the CDN team to update this list, and will enhance the visibility of your work.
