One of the physical components of a SAFE product, are the XML Schema files. These files provide the representation information of the data held by a SAFE product. In order to represent the binary information, SAFE defines specific markups that annotate the XML Schema documents to provide information on the physical structure, i.e. the so-called SDF markups. Thanks to these specific annotations, the contents of the binary files are described up to the bit level with a common technique as for XML documents.
SDF (Structured Data File) is XML based and provides bit-level description but it is a proprietary language not standardised.
A new standard and/or open language should be analysed to be adopted for data file representation in the new SAFE specification.
Other candidates currently used for archiving technology shall be considered if they are identified.
