description | A group of entries within a composition, topic or category that have a logical association with one another.
The representation of a single observation or action might itself be multi-part. The data might need to be represented as a nested set of values, as a table, list, or as a time series. The Cluster class permits such aggregation within an entry for such compound data.
Examples include "Haematology investigations" which might include two or more distinct batteries.
A cluster may contain batteries and/or individual entries | |
