Product file history

In 1977, when the above review was presented and published, the history of the s-triazine herbicides was already 25 years old, with the first synthesis of these chemicals completed in 1952. The filing of the first basic triazine patent case in Switzerland was on August 16, 1954, and the first commercial products appeared on the market in 1956, following the approval of simazine for use in corn by federal authorities in Switzerland on December 3, 1956. Several other agrochemical companies started immediately to work with their own s-triazine variations, using other radicals or amino-functions on the s-triazine ring. This further research was also briefly reviewed in Knusli s 1977 paper. 

As shown in Fig. 7.2, each XML file will be represented by an instance of the class DocumentVersion. The version history of the files can be indicated by the relations hasPredecessor and hasSuccessor, as explained in Subsect. 2.3.3. The hasContent relation is employed to denote the contents of the XML files through concepts from the OntoCAPE ontology (cf. Subsect. 2.3.4). A finer-grained description can be obtained by decomposing each file into its structural entities, represented through instances of the Product class, and... 

Standards for software identification and traceability (e.g., for each software item—unique name/reference, version, project/ product reference, module description, list of build files, change history, traceability to design document) (see Appendix C, section 5, Item 1.2)... 

It is unfortunate that many a safety case is constructed before product launch only for it to be filed away in the annals of history after go-live. The safety case is a key document for the lifetime of the product but its content shouldn t be static. There is much to be learnt from operating a system in a live environment and the world changes in ways that could impact the validity of the arguments set out in the safety case. It is the nature of the software industry that products evolve, new functionality is introduced and old methods are deprecated. Clinical processes change too and in a short space of time there can be extensive divergence between the original safely case and the product as it stands today.
