The overall aim of OASIS is to provide an online index to the mass of archaeological grey literature created in the UK and to help in the flow of information from data producers, such as contracting units and community groups, through to local and national data managers, such as Historic Environment Records (HERs) and National Historic Environment Records (eg. Canmore , Coflein, National Heritage List for England) and receiving repositories such as museums and archives.
The workflows followed by each national body differ. More information about these workflows and how different national bodies interact with OASIS can be found on the OASIS national area pages.
