Data Access Protocol-compliant servers (DAP)
REST web service based protocol designed for science data. There are multiple software packages which implement DAP, e.g. OPeNDAP Hyrax and THREDDS. There is current development to make Hyrax and THREDDS DataONE-enabled.
EU BON recommendations:
Where gridded data are to be used in the development of EBVs or as a gridded data product derived from species observation data, DAP-compliant servers may be an appropriate choice, particularly where making this data available to the modelling communities is concerned.
