Starting with the smallest addressable unit, the DataModules under the use of different Document Type Definitions (DTDs) or schemas has to be supported.
Furthermore, the publications, in process review forms (IPRFs) in later S1000D versions known as comments, for authoring reasons must be provided.
The Info Object instance (XML file, using a special Document Type Definition) consists of DM- and ICN-references to guide the loading process into a retrieval system and to build the table of content, partly the list of applicable publications LOAP.
Data exchange routines and automatisms are the most important reason to develop a CSDB, to ensure a process reliability.
The identifier of the DM is the data module code (DMC) found within the sgml/xml file and expressed in the filename plus related extension.
To implement all kinds of authors and illustrators work including all supporting processes like validation and production of IETD the CSDB used by AIRBUS Defence and Space supports workflow engines and offers standardized interfaces to import and export data.
