20. Settings hierarchy

20.1 Introduction

GeoNetwork stores many options and information inside the Settings table. Information is grouped into hierarchies where each node has a key/value pair and can have many children. Each key is limited to 32 characters while each value is limited to 250. The 2 top level hierarchies are system and harvesting.

In the following sections, the indentation is used to show hierarchies. Names in bold represent keys with the value’s datatype in parenthesis. An italic font is used to indicate basic types (string, integer, boolean) while normal font with a | is used to represent a set of allowed values. Regarding the boolean type, value can be only true or false. A missing datatype means that the value of the node is not used. Square brackets indicate cardinality. If they are missing, a cardinality of [1..1] should be considered.
