Tree Fields

Certain fields in the Calm databases are designated as Tree fields, such as the RefNo and the ObjectNumber fields in the catalogue database or Location in the Locations database.

Tree windows allow you to view the structure of the “tree”; beginning at the root term and branching off from there. The tree windows may also be used to navigate between the records in the tree.

Multiple hierarchical levels in the tree are indicated to the system by using a separator in the tree field. This is usually a forward slash (/) character as in the Archive RefNo tree in catalogue records or the location tree in location records. However for the Museum ObjectNumber tree in the catalogue database the full stop (.) character is used as a separator.

Further information on working with trees is available in the Trees and Searching on Tree Fields sections of this manual.
