Thank you Alex for clarifying the context.

I'd like to bring this up again before our next call, because we need to
reach an agreement on the use case template now.
The discussion page at [1] is currently empty. So we will probably need to
discuss the template again on next call.
Maybe we can have a discussion on each part of the template and decide if we
keep it / drop it / edit it.

Following the discussions we already had, we could start with the following
:

Name -> no problem,  keep

Owner -> no problem,  keep

Background and Current Practice -> no problem,  keep

Goal -> to be edited to make it clear that it's meant to be the goal of the
actor in the scenario, not the goal of the use case

Use Case Scenario -> no problem,  keep

Target Audience  -> added by Joachim. The group finds it useful but it
should be optional. To be edited : we need to add guidelines on how to fill
it.

Application of linked data for the given use case -> not discussed yet. Is
that clear to everyone ?

Existing Work -> to be edited to add prototypes

Related Vocabularies  -> no problem,  keep

Problems and Limitations -> not discussed yet. Is that clear to everyone ?

Related Use Cases and Unanticipated Uses (optional) -> not discussed yet. Is
that clear to everyone ?

Library Linked Data Dimensions / Topics -> confusing. Drop it, or keep it
only for curation ?

References -> no problem,  keep

Prototypes and Applications  -> added by Joachim. Drop it: content to be put
under "existing work".

Comments welcome on this proposal. I'm copying my mail in the discussion
page of the template, so you're welcome to make your comments there.
Emmanuelle

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).

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].
