June 7 - 9, Digital Data 2021: Digital Datas Grand Challenge: Expanding Discovery Across Multiple Domains (virtual)


Plazi will introduce the proposed term for the new class MaterialCitation for the TDWG vocabulary.

The corpus of biodiversity literature represents the scientific output produced in biodiversity research. Each species has at least a taxonomic treatment, but in many several hundreds treatments exist. These are all interconnected and composing the entire catalogue of life. Each of these treatments is implicitly (sometimes explicitly) linked to specimens in natural history collections. Already in the advent of taxonomy Linnaeus kept a reference collection for his seminal works which he cited by listing its geographic origin in a regularly occurring section in the treatments. These material citations range today from a summary of specimen data (e.g. 20 paratypes from Columbia” ) to very detailed, normalized, augmented data including specimen, collection, and gene accession codes as well as collectors, date, collecting methods of host, etc. These material citations represent one of the best curated data about a specimen, full of links between different resources. This is a citation of a specimen and not a formal specimen record, which adds to the confusion on how to handle them. For this reason, we submitted “MaterialCitation” as a new class to TDWG’s Darwin Core standard, which is now open for public review. In this lecture we will explain the new term, its role in the biodiversity knowledge graph and to create digital accessible knowledge.
