Oct 18-22, 2021. TDWG 2021 — Virtual Annual Conference

October 18-22, 2021: Virtual Conference

As we (TDWG) continue to connect people and biodiversity data globally by virtual means in these globally uncertain times, TDWG 2021 will be composed of symposia, workshops, contributed oral and poster presentations, demos, and discussions, as well as keynotes and social events. The Interest/Task Group working sessions will be held separately during the month following the virtual conference (November 2021).

SYM18 Discovering known biodiversity: Digital accessible knowledge

Session Type: Symposium (no unsolicited presentations considered)

Organizers: Donat Agosti, Plazi, Bern, Switzerland; Alexandros Ioannidis-Pantopikos, Zenodo - CERN, Meyrin, Switzerland

Scientific publishing is building up our knowledge by connecting facts using an intricate network of implicit and explicit citations. Taxonomic publications are exceptionally rich beginning with the explicit citation of publications, to implicit citations provided by taxonomic names, treatment citations, materials, actors, collections to a domain-specific vocabulary. In a sense, we are still living in an analogue world because most of our knowledge is not even digital or most of it is made for human consumption at best and not as digital accessible knowledge (DAK). DAK are facts that are both human and machine readable and they are open, findable, accessible, interoperable and reusable, proven as such by their reuse by external services such as the Global Biodiversity Information Facility (GBIF). A second aspect of DAK is that its citations are annotated with respective identifiers. This allows easy integration and/or connection with existing DAK.

Discovering known biodiversity is a challenge taken on by Plazi. This requires defined target resolution of data, sustainable infrastructures, workflows, reference vocabularies, resources, and strategies to discover and convert a daunting corpus of ca 500 M pages of rapidly ever-growing publications. Current technical and persistent identifier developments will be highlighted.
