As soon as the tank is full, refuelling stops.
At that point, in my view, the display gives
no information about the fuelling process,
but only delivers information about the
final condition. You can see the total price
you must pay and the amount of fuel that
is delivered. Once you put the hose back in
its place, the payment transaction is
completed and committed. You then have
the choice to receive a receipt on paper,
partly with the same information
supplemented with extras that may be
useful for you for administration and
declaration purposes. It may also be useful
when there are problems with the delivery.
As soon as a new customer arrives and
starts refuelling his car, all the displays are
set to zero. The case has been closed.
This activity has two perspectives. The
customer and the supplier who owns the
pump. Both partly use the same
information, only the usage context - the
primary context - is different. You need
the information for refuelling and, in the
case you keep track of expenses, you can
reuse the information for that purpose.
The primary context of the supplier will
also be the refuelling itself and the final payment transaction. In the back office of
the supplier the information is needed for stock management and other forms of
administration. When it is needed for business intelligence it can even become part
of a data warehouse. The exchange of information between both parties takes place
through the information on the display of the pump and the printed receipt. The
information you receive on the receipt is also part of the information the supplier
A short conclusion: we have an activity, i.e. refuelling, with a primary context
triggered by information (signal about the empty tank) and with the necessary
information objects that are exchanged via visual (display) and physical (print)
ways. These are the three basic components of the aforementioned "something":
a context, an activity and information objects, the main components of the
information model that will be discussed in the next paragraph.
Leeuwarder Information model (LIM)
The model based on the concept of "something" represents meaningful information
as the only constant factor in a continuum of time and space

Just three entities are the essence of this model. First, the information has to be
provided with context. To process information, it should be contained in structured
form in an information object. For information to come into existence an event or
transaction must take place. Part of an event or transaction are the different ways of
exchange and communication.
The Information is central and has several invariant constant elements which
underpin certain qualities. Qualities like meaningful based on context, structured as
in the form of an information object and trustworthy by the way the context is
described, the information object is structured and fixated, and the activity is
executed. All qualities that are also essential composing parts of an archival record.
In this model trustworthiness and veracity are derived qualities.
The context defines the setting in which the information has come into existence
and at the same time, the information is used.
When speaking about use, I am talking about the primary use and therefore it is a
primary context. Information can always be reused in other contexts. Within the
context the characteristics of the information object and the activity are described
