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" on page215 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" on page83.
Attributes are stored in a collection container object, just like the Node's "Fields" on the facing
page. 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.
Warning
Attributes are intended for system-defined data. Please restrict user-defined data to
Fields, and do not modify the Attributes.
Properties
Name Type Description
Count Integer Returns the number of elements in the collection.
