Improved assurance case development in GSN diagrams and automatic layout are the main enhancements in the new PREMIS version released last week. It is now easier to work with diagram pages, which no longer have a size limit. Editing diagrams is faster, navigation has been improved and working with GSN is now more effective.
Now you can reviews and assess arguments directly in GSN diagrams. Diagrams provide a platform for collaborative development of arguments supported by evidence, progress reporting, self-assessment and third-party reviews.
When working with large assurance cases, you create argument modules and use interfaces to connect them. Interfaces allow you to easily navigate from one GSN diagram to another.
GSN diagrams in PREMIS enable quick development of assurance case arguments, and you can also use the argument tree view which supports more features including argument versioning.
