Project Title

CCSDS XML Guidelines



Document Number



1.01 System Architecture Working Group

Document Type


Description of Document

One of the key kinds of information artifacts that CCSDS produces today are XML schema. These have grown over the years, but without any overall information model or XML guidelines they are in something of a state of disarray. Because they use different styles and different terminology the ability to re-use them effectively is limited. \n \n This project is to provide a set of guidelines and, over time, to work with the affected WGs to bring current specs in line. Identify source of adequate XML schema development guidelines, develop draft and review\n - Adopt suite of schema analysis and validation tools\n - Extract set(s) of common terms as library elements\n

The XML guidelines are expected to leverage similar work done in ESA and also by Google, as well as other organizations. This is not unique to space nor CCSDS, but we do need a set of guidelines that will work in our context of interoperable and re-usable standards for space. \n \n

Resource Comments

Since ESA has produced a set of guidelines we think that they can leverage this for the purposes of CCSDS. Some adjustments to this approach, leveraging the experiences from Google and other developers of major information management organizations, should be made.
