The ADAPT SMART glossary provides working definitions for common terms relevant for the consortium and includes references. The glossary is based on the input from members of the ADAPT SMART consortium representing different stakeholder groups. The definitions are based on relevant legislation or literature sources and written in the context of the ADAPT SMART project; where applicable, an EU perspective was chosen. Some definitions have been created without any direct reference source and these are shown as ‘ADAPT SMART’. This is a working document and will be updated during the lifespan of the ADAPT SMART project.
