HDX Data Model: FITS, NDF and XML Implementation
David Giaretta, Mark B. Taylor, P. W. Draper, Norman Gray, Brian McIlwrath · Durham Research Online (Durham University) · 2003
A highly adaptable data model, HDX, based on the concepts embodied in FITS and various proposed XML-based formats, as well as Starlink’s NDF and HDS will be described, together with the Java software that has been developed to support it. The aim is to provide a flexible model which is compatible with FITS, can be extended to accommodate VO requirements, but which maintains enough mandatory structure to make application-level interoperability relatively easy.
