**People Identifiers workshop** 25-26 January 2023 at 09:00 – 17:00 (CET) Place : Natural History Museum - University of Oslo Sars' gate 1, 0562 Oslo, Norway **Organisers** Quentin Groom, Torkild Bakken, Elspeth Haston, Eirik Rindal (local organizer), Marcella Owick Rydmark (local organiser) **Introduction** Data on people are critical to giving credit for scientific outputs, understanding the provenance of collections, linking biodiversity data, and ensuring compliance of collections with regulations. Throughout Mobilise we have been working towards promoting the use of biographical data and person identifiers to improve collection data, connect collections together and to perform innovative research. Starting in Sofia in 2019 we developed the argument for why people and their data are so important to collections (Groom et al. 2020). Together with the CETAF Information Science & Technology Commission we created a pilot using person identifiers to link together herbarium collections (Güntsch et al. 2021). Furthermore, we have also been working in the TDWG Task Group on People in Biodiversity Data to create a new extension to Darwin Core and will soon publish a compendium on the disambiguation of person names for biodiversity collections. As a logical next step we propose a workshop to take concrete steps to mainstream person data in museums and herbaria based on our pilot implementations and recommendations. This will be achieved through an event that helps more collections adopt person identifiers, that will disseminate guidance and best practice developed during Mobilise. In parallel we will also run a datathon (a data-focused hackathon) to demonstrate how person data can be used in research and visualisation and to facilitate conversations between researchers and curators about prioritisation of the effort. The specific objectives of the workshop will be to: - Increase the number of collections linking their person records to identifiers - Increase the number of identified collectors of specimens on Wikidata - Work toward institutional policies requiring living collectors to register for an ORCID - Demonstrate how these data can be used to do research - Increase the use of disambiguated person data for validation and research In order to achieve these objectives we will invite people with a diverse background and skills includin: - Experts in person disambiguation in collections - Collection curators interested in working with person data in their collections - Data scientists interested in analysing person data - Data aggregators - Collection management system developers **Output** We envisage a report/paper that details examples of how person data can be used in research and dissemination, but also how collections can implement identifiers in their collections. We also foresee that this workshop will support task 7.3 In BiCIKL on using Wikidata to link and validate entities discovered in specimens. It will also support work proposed for work package 3 of TETTRIs on mapping of taxonomic expertise in Europe. This document would potentially follow the model of the CETAF stable identifiers.
