Hi everyone, In addition to our telco from yesterday some comments to make sure the templates are applicable for upcoming UCs. First, I'd like to give some extra information regarding our template elaboration. Kai and I are both computer scientists so we are driven by experience of UC modeling (UML etc.) in the context of software development. As a consequence our chosen approach is similar to the one used in software engineering. It's a user-centered approach. That means we try to identify user needs by analyzing the interaction of an actor (librarian, end user as data consumer, data provider - every imaginable user!) with a particular system (an already existing one or just an idea of a system). The conclusion of system requirements (in our case requirements for linked data in libraries) is in software engineering processes the next step and usually by use cases in this form pretty easy. However, this doesn't mean this approach is best for LLD-XG needs. Nevertheless, we would first like to make sure that you got our thinking and then we can discuss the need to modify the UC gathering process to suit LLD XG requirements. >From that on we should have a closer look to the single parts of the UC template and the descriptions therefore. The discussion yesterday showed the ambiguity of the goal-section. Karen stated the major goal, but actually we intended to highlight (1) the actor's goal in this particular UC and (2) how linked data can support this specific actor's goal. This is also pointed out by the comments of Kai in the Open Library UC [1]. We have to make sure that the template is unambiguous regarding our common understanding of it's purpose and intended use and after this our UC template should probably be ready to go...
