The Biodiversity Information Standards (TDWG) Material Sample Task Group*1 kicked off in the third quarter of 2021. The group’s initial focus was to

1) achieve a clear conceptual delineation between the terms MaterialSample, PreservedSpecimen, LivingSpecimen, and FossilSpecimen (the terms used in basisOfRecord in the current DwC-A provided to the Integrated Publishing Toolkit (IPT) for describing physical material)

2) define the conceptual relationship between these terms and the term Organism

3) consider the possible implications of the activities towards the diversification of the Global Biodiversity Information Facility (GBIF) data model*2 and what standards already exist that should inform our work.

Based on this conceptual work, the group is now developing a concrete proposal for a clarification of a MaterialSample class with its own properties. Our presentation will provide a brief review of the task group's progress and our thoughts about what comes next.
