ABCD (Access to Biological Collection Data, Holetschek et al. 2012) and DwC (Darwin Core, Wieczorek et al. 2012), are TDWG standards for documenting the occurrence of organisms in nature and/or collections, whether as specimens or observations (i.e., unit-level data), and are used for a wide range of applications. Since 2019, the working group has been investigating ways to enable a closer link and integration of these standards (Blum et al. 2019).

This presentation will summarize the results of the September 2020 workshop of the ABCD/DwC Alignment Working Group as part of the TDWG 2020 Virtual Conference Working Sessions Week. Prior to the workshop, we will have collected use cases for the application of the standards, which will have been analysed and discussed in the workshop itself. On this basis, smaller working groups will have been formed to address technical, organisational, and sociological aspects relevant for an alignment and future maintenance of ABCD and DwC.

The results of these working groups, as well as the general summary of the workshop and the planned next steps of the ABCD/DwC Alignment Working Group will be shown and discussed in this presentation.
