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...

Cheers, Alexander
