What is FAIR?

Preamble: We strive to make marine image data FAIR. We maintain metadata profiles to establish a common language of marine imagery, we develop best-practice operating procedures for handling marine images and we develop software tools to apply the vocabulary and procedures to marine imagery.

FAIRness#

The buzzterm FAIR is an acronym for Findable, Accessible, Interoperable and Reusable. Which you probably knew already. Sorry. But in case you didn’t: its the big idea, currently driving research data management (RDM) and a massive challenge for RDM infrastructure providers, maintainers and users. But it is also a fantastic opportunity to open up research by making research efforts more prominent and results more reliable. It appears everywhere nowadays, most importantly in project calls and thus project proposals. So while there is also no way around it, embracing this new data culture will change the face of research for the better!

FAIR Digital Objects for images (iFDOs)#

Achieving FAIRness and Openness of (marine) image data requires structured and standardised metadata on the image data itself and the visual and semantic image data content. This metadata shall be provided in the form of FAIR digital objects (FDOs). These documentation pages describes how FDOs for images (aka iFDOs) shall be structured. If you want, an iFDO is a human and machine-readable file format for an entire image set, except that it does not contain the actual image data, only references to it through persistent identifiers!

And where are the images?#

That is entirely up to you! iFDOs only contain metadata - including information on where images can be found. Ideally image data is also openly accessible, but this is not mandatory. Your images will likely be stored in a media asset management system (MAMS) that is ideally web-accessible and where the persistent identifiers in an iFDO file link to. So its easy to share image metadata data with iFDOs (they are small enough to be emailed if needed) and you simultaneously share the image data without moving it physically.

Journal publication#

The principles and workflows - described on these pages here - in detail have been published as a peer-reviewed journal article in Nature Scientific Data: https://doi.org/10.1038/s41597-022-01491-3

Please cite this article in your own works in case you use iFDOs for your data.

Standard Operating Procedures (SOPs)#

More hands-on material on creating and using iFDOs is available in two OceanBestPractices Bundles. One on iFDO Creation and one on Image curation and publication.

Vocabulary terms - what are images?#

We use the following wording - based on Dublin Core - throughout these pages: images are both photos (still images) and videos (moving images) acquired by cameras, recording the optical spectrum of light. Still imagesare static visual representations, while moving images are a series of visual representations imparting an impression of motion when shown in succession. An image set is a collection of at least one, but usually many, images. We further use as placeholders for specific information (like a variable).
