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217 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 the facing page.
Attributes are stored in a collection container object, just like the Node's "Fields" on page243.
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.
