Structured Data File
SDF is a critical implementation for accessing scientific or legacy data: it wraps around binary or ASCII files content according to an external description of the data structure. This external description is based on XML Schema documents, following a W3C recommendation. SDF makes use of set of extra markups to achieve the complete description of binary data representation, when this information could not be derived from the standard XML Schema markups: the SDF descriptors remain however fully compatible with the standard.
A large set of XML Schema’s that describe hundreds of data types are already available and are candidate for reuse in the framework of the present project.
