This presentation was part of an “Orientation to ARDC services and expertise” series, specifically aimed at people involved in one of the ARDC co-investment projects commencing early 2021. In addition to co-investment of money, ARDC contributes expertise and services in a range of areas: research vocabularies, persistent identifiers, data discovery catalogues, metadata issues, licensing, governance, underpinning infrastructure (e.g. Nectar Research Cloud) and more. ARDC can also connect projects to national and international communities and initiatives trying to solve common challenges and outline best practice. This session explained why and how vocabularies are used, and how to find and create vocabularies using ARDC’s Research Vocabularies Australia service. A video recording of this session can also be found on ARDC's YouTube channel:https://youtu.be/cTO9adMFcC0
