Attributes

An Attribute is a read-only, system-defined element: a name/value pair, where the name is case-insensitive. It holds certain information about a certain Node in the Metadata structure. This information can be static (e.g. the size of a physical page) or evaluated on-the-fly (e.g. the number of documents in a group).
Attributes are non-repetitive (i.e. name is unique) and do not persist through Metadata recreation.

For an overview of Attributes and the Node types in which they are available, see the Metadata Attributes reference.

Attributes are stored in a collection container object, just like the Node's Fields. As is the case with the different types of Nodes, both collections share a number of methods and properties. The Fields collection however has additional methods to support multiple entries with the same name, which is forbidden with attributes.

Caution: Attributes are intended for system-defined data. Please restrict user-defined data to Fields, and do not modify the Attributes.
