||The description and values of ITEMs will change over time, but most of these will not be tracked as a STATE. The decision as to when to track changes in the condition or cirmcumstance of an ITEM will be where a city wishes to bring about a change of that STATE.
Changes to STATE are often the outcome of EVENTs.
An OBJECTIVE can be described in terms of a desired change of STATE.
A STATE can be actual or potential, and can include Risks and Issues.
