The GrADS-DODS Server (GDS) is an OPeNDAP (a.k.a. DODS) server that is based upon a Java Servlet architecture known as Anagram. Anagram was designed to accommodate back end applications other than GrADS, but few attempts have been made thus far to employ Anagram for this purpose. PMEL is developing a Ferret-DODS Server (FDS) analogous to GDS but using the Ferret application as its back-end. The FDS provides access via the OPeNDAP protocol to the various file formats Ferret is capable of reading: netCDF, tab-delimited, FORTRAN-formatted ASCII and binary, non-standard-compliant netCDF data sets, etc. Through the use of Ferret scripts these formats may be served in a semantically consistent fashion (typically using the COARDS conventions). Missing units, titles and coordinates may be supplied; permuted and reversed axes may be adjusted, etc. The FDS also allows Live Access Servers (LAS) to produce OPeNDAP URLs as an output product with only minimal changes to an existing LAS configuration. This papers describes the FDS and discusses its role within the LAS and DODS communities.
