SEDS Schema | F. Torelli | CCSDS SOIS WG, Darmstadt | 17/04/2012 | TEC-SWS | Slide 3 ESA UNCLASSIFIED – For Official Use Objectives of SEDS Schema One CCSDS book  What target color? One XML Schema  As part of the same book? The XML Schema shall be the template for all the SOIS EDS instances. The XML Schema shall be “modular”, to allow different entities to fill different sections if necessary. The XML Schema shall be built using SOIS DoT and SOIS C&DA Services Primitives.

SEDS Schema | F. Torelli | CCSDS SOIS WG, Darmstadt | 17/04/2012 | TEC-SWS | Slide 5 ESA UNCLASSIFIED – For Official Use XML and SEDS Schema - Technology Interface sections  XSD Mapping sections  SCXML + MathML XSD describes in XML the static interfaces. SCXML describes in XML state machines, allowing to represent protocols and operations sequences. MathML describes in XML mathematical functions, allowing to represent transfer and calibration functions.

SEDS Schema | F. Torelli | CCSDS SOIS WG, Darmstadt | 17/04/2012 | TEC-SWS | Slide 8 ESA UNCLASSIFIED – For Official Use XML and SEDS Schema - Sections Service I/F sections should describe the service primitives and the related parameters. The mapping I/F sections should use as inputs the service interface of one layer and as output the service interface of the layer above (or below). The types and terms used inside the schema should belong to the SOIS DoT. The actual device SOIS EDS shall contain multiple instantiations of the sections above if multiple (syntactic or semantic) types are supported as input parameters.
