Preserving and disseminating your scientific images

MédiHal is an open archive which enables to deposit image-type scientific iconographic documents (scanned images, digitalised photographs, digital photographs, synthesis images or digital simulation images, etc.). These iconographic documents are stored in a secured warehouse, with strong digital and human infrastructure, with backup copies of the images and of their metadata.

In the spirit of the international movement in favour of open access to scientific data, the images deposited in MédiHAL are accessible on line i.e. immediately after deposition, or after a mobile barrier (which remains modifiable), in compliance with the intellectual property of the authors.

Just like the HAL open archive, MédiHAL is based upon self-archiving by french scientists (researchers, lecturers-researchers) and supervision staff members in superior education and research. Self-archiving is strongly encouraged so as to increase visibility, accessibility, diffusion speed and impact of iconographic data.

The deposition of a document on MédiHAL is very similar to the presentation of scientific findings in a conference: the works are divulged publicly which may, taking into account the European regulations, prevent the filing of a patent in some cases.

MédiHAL is neither an institutional nor a thematic photolibrary, it is a data warehouse, open to all scientific disciplines. Each deposit, as in HAL, is checked for format before being put on line.

MédiHAL is developed through the Centre for direct scientific communication (CCSD) and the National centre for the digitisation of visual sources (CN2SV) of the CNRS, and with le support of the ADONIS Scholar Infrastructure of the CNRS. Since june 2010, all photos and images hosted in MédiHAL are archived for long term at CINES (Montpellier) by the OAIS process.

What can we deposit?

The iconographic data must be scientific data derived from:

  • scientific research projects, in progress or past
  • or scientific programmes, in progress or past
  • individual or collective scientific collections

These images may have been generated when preparing a scientific publication or putting together the iconographic documentary collection of a laboratory, of a team, etc. MédiHAL may also serve as a warehouse for iconographic data enclosed with an electronic article deposited in HAL, in an electronic journal, a research book, etc.

MédiHAL manages:

  • the scientific photographic collections of researchers and lecturers/researchers
  • the photographic and iconographic collections of research libraries and documentation centres

MédiHAL has the capacity to host large collections or series of images and does not select the volume of data.

In this first version, MédiHAL hosts fixed images in JPEG and TIFF formats. Images may be documented either via their IPTC and EXIF metadata or via an entry form (see help). These scientific metadata are highlighted by diffusion via the OAI-PMH protocol (Open Archives Initiative Protocol for Metadata Harvesting) and by RSS (see the RSS section).

Geo-localisation of deposited data

The images deposited in MédiHAL can be geo-referenced. This geo-referencing is integrated to the deposition form by a cartographic access coupled with the GeoNames.org geographical referential. The images containing GPS metadata will be automatically positioned on the map.

Share images and photos

MédiHAL’s users are governed by common good usage rules of data in the scientific world: respect for original works and authors’ quotation, with institutional authorizations. The author transmits to MédiHAL, on a non-exclusive basis, the right to diffuse his/her work in conditions of free and non-restricted access. The intellectual property of the documents deposited remains entirely with the author(s). It is also possible to franchise the deposited data under Creative Commons. These licences define various frameworks of use of the data.
