Dear All,
CIDOC CRM - CRMsci - Issue 308
The CRM-SIG discussing about the proposal of introducing S19 Encounter
Event in CRM core, rejected the move. It is decided that it is well
placed in CRMsci since it contains all issues of observation.
Also it is decided to update scope note in order to clarify difference
between observation and data evaluation with paradigmatic example the
identification of objects on photographs (a data evaluation)
My homework: I have added to phrases to the scope note of S4 Observation:
S4 Observation
Subclass of: E13 <cid:[email protected]> Attribute
Assignment
Superclass of:S21 <cid:[email protected]> Measurement
S19 <cid:[email protected]>Encounter Event
Scope note:This class comprises the activity of gaining scientific
knowledge about particular states of physical reality gained by
empirical evidence, experiments and by measurements. We define
observation in the sense of natural sciences, as a kind of human
activity: at some Place and within some Time-Span, certain Physical
Things and their behavior and interactions are observed, either directly
by human sensory impression, or enhanced with tools and measurement
devices. The output of the internal processes of measurement devices
that do not require additional human interaction are in general regarded
as part of the observation and not as additional inference. Manual
recordings may serve as additional evidence. Measurements and witnessing
of events are special cases of observations. Observations result in a
belief about certain propositions. In this model, the degree of
confidence in the observed properties is regarded to be “true” per
default, but could be described differently by adding a property /P3 has
note /to an instance of S4 Observation, or by reification of the
property /O16 observed value/. Primary data from measurement devices are
regarded in this model to be results of observation and can be
interpreted as propositions believed to be true within the (known)
tolerances and degree of reliability of the device. Observations
represent the transition between reality and propositions in the form of
instances of a formal ontology, and can be subject to data evaluation
from this point on. For instance,detecting an archaeological site on
satellite images is not regarded as instance of S4 Observation, but as
an instance of S6 Data Evaluation. Rather, the production of the images
themselves is regarded as instance of S4 Observation.
