Each table has groups of similar information and follows a hierarchy that expands with increasing
levels of granulation from a two digit code to six digits. For example, in the Administrative and
Commercial group of the entities table Commercial Administrative Buildings are classified as 25-50
with small single office buildings having a lower level classification of 25-50-70. This principle of
increasing granulation applies to all tables.

There are no hard and fast rules about what is right, so choosing the appropriate table is subjective.
The following are all possibilities for classifying a prison leaving the choice of the most appropriate to
the users but with some consensus sought across the project team.

Terminology is another issue, so that words
that we use and understand among ourselves
may not be as clear to others. The language
in classification therefore has to be generic
but project specific information can use more
familiar language.
For example, a prison is described generically
as a Detention complex or a Detention Activity.
Although the classification uses a generic
term, the project specific term can still be
Holloway Prison and the description can either
be of a complex or an activity – both are valid
but a client may have a preference for which is
most appropriate.
Another example is that ‘station’ can be used
to describe a place for catching a train or bus,
but it is also used to describe a ‘fire station’ and
a ‘work station’. So the classification has to be
generic so that it is clear what is being coded.
A station is an embarkation and disembarkation
complex generically but will be known as
a station as far as the project is concerned.
