WMO_DelimitedString

Hierarchical keyword taxonomies - (Class diagram)

Type:		Class    CharacterString
Status:		Proposed.  Version 1.0.  Phase 1.0.
Package:	Metadata Extensions     Keywords:   
Detail:		Created on 19/10/2006.  Last modified on.19/10/2006.
GUID:		{E703A78F-37DA-45b5-996A-9778E9CF4E0F}

WMO_DelimitedString enables a keyword from a hierarchical taxonomy - such as NASA's GCMD Science Keywords [http://gcmd.nasa.gov/Resources/valids//gcmd_parameters.html] -  to be expressed. The delimiter (token) [default value = "|"] is inserted between 'levels' in the hierarchy.
