OPeNDAP: Open-source Project for a Network Data Access Protocol
OPeNDAP is a framework that simplifies all aspects of scientific data networking.
OPeNDAP provides software which makes local data accessible to remote locations regardless of local storage format. OPeNDAP also provides tools for transforming existing applications into OPeNDAP clients (i.e., enabling them to remotely access OPeNDAP served data).
OPeNDAP software is freely available.
