1 Scope This International Standard defines a conceptual schema for observations , and for features involved in sampling when making observations . These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities.
Observations commonly involve sampling of an ultimate feature -of-interest. This International Standard defines a common set of sampling feature types classified primarily by topological dimension, as well as samples for ex-situ observations . The schema includes relationships between sampling features (sub-sampling, derived samples). This International Standard concerns only externally visible interfaces and places no restriction on the underlying implementations other than what is needed to satisfy the interface specifications in the actual situation.
