Unqualified (short) name of this node wrt the tree

escapedname

protected String escapedname

Escaped version of shortname

parent

protected DapNode parent

Parent DapNode; may be: Group, Structure, Grid, Sequence (for e.g. variables, dimensions), Variable (for e.g. attributes or maps).

dataset

protected DapDataset dataset

fqn

protected String fqn

Fully qualified name; note that this is always backslash escaped

attributes

protected Map<String,DapAttribute> attributes

DAP Attributes attached to this node (as opposed to the xml attributes)
