<p>As anyone reading this has probably been on expo and you might think that we can skip the <strong>real-world level</strong>. Not so: the multiplicities (the number of participants in the association) of the relationships between the different cave survey artefacts can be surprising.
<p>The <strong>specification level</strong> is where the action is.
This is where we decide which aspects of the real world <em>we will ignore</em> and what <em>extra concepts</em> we need to make things work.
<p>So we ignore who is resident at top-camp (even though today we record this religiously because of the tax implications for the GastHof at base). We do need to track the in-computer associations between survex files: the *include tree, what directories they live in, what wallet-directory they relate to, and all the individual survex blocks of survey measurements within each survex file.

<h3 id="cookanddaniels">Cook & Daniels - Three Levels</h3>
<p>From <a href="http://www.syntropy.co.uk/syntropy/designing-object-systems.pdf">Cook and Daniels</a> (online PDF, 400 pages, pp10-11):
<div style="text-align: left; font-size: smaller; margin-left: 7%; margin-right:15%">
<p>
"In this book we present three kinds of object-oriented model. The first kind, which
we call <em>the essential model</em>, considers the model to be a description of some real or
imaginary situation, which may or may not contain software. We use the word
situation rather than system because system has so many possible meanings including
the software we may be trying to build, and rather than world to emphasise that we are
considering purposeful systems situated in a context rather than trying to describe all of
some supposedly objective reality. <em>The purpose of building the essential model is to
understand and establish the facts about this situation.</em> The building blocks which we
use to build essential models are objects (actually object types) and events (actually
event types). An essential model is built by drawing annotated diagrams, and
interpreted as descriptions of sets, functions and sequences with meanings in the
situation being described.
<p>
In the second kind of model, called <em>the specification model</em>, we are concerned with
specifying software. To create a specification model it is necessary to establish <em>which
parts of the overall situation will be implemented in software</em>. In some cases this might
be a large part of the situation, whereas in others it might not be a part at all. The
activity of specifying exactly what is to be implemented in software is quite different
from the activity of establishing the facts about the overall situation; however both of
these activities would conventionally fall under the heading of analysis. Like
essential models, specification models deal with objects and events and are built by
drawing annotated diagrams. They are interpreted as a description of the abstract
stimulusresponse behaviour of the software. The specification model describes
software at a high level of abstraction, and in particular says nothing about internal
sequencing or concurrency. An important part of building a specification model is the
allocation among object types of responsibility for aspects of software behaviour.
<p>
The third kind of model, <em>the implementation model</em>, is concerned with establishing
patterns of control flow within the software. In this model we take into account the
fact that computer programs have a limited number of well-defined flows of control,
which execute at a finite speed. The building blocks for implementation models are
objects and messages. Object interactions are described as messages sent from one
object to another, and the implementation model describes message sequencing and
concurrency control. Annotated diagrams are used again, although in the
implementation model our repertoire of diagrams is richer than for the other kinds of
model."

and a suvex-file editing page will open, pre-populated with an example template
for survex data, most of which you will delete and replace. Edit this template and type in your own data.
<p>You can save your work by pressing the "Save this edited svx file" button, but it
will refuse to save until you have hand-edited out all the template material in [square brackets].
<p>As you edit it, you can

<p>You may see a number of error messages below the editing window: <em>read them and understand them</em>. If you don't understand them, <em>ask someone</em>.
