HFileHierarchy

Classifier plugin for generating hierarchical classifications based on a supplementary structure file.

The following table lists all of the configuration options available for HFileHierarchy.

Option	Description	Value
HFileHierarchy Options
metadata	(REQUIRED) A single metadata field, or a comma separated list of metadata fields, used for classification. If a list is specified, the first metadata type that has values will be used. May be used in conjunction with the -firstvalueonly and -allvalues flags, to select only the first value, or all metadata values from the list.
firstvalueonly	Use only the first metadata value found.
allvalues	Use all metadata values found.
hfile	Use the specified classification structure file.
sort	Metadata field to sort leaf nodes by. Leaves will not be sorted if not specified.
reverse_sort	Sort leaf nodes in reverse order (use with -sort).
hlist_at_top	Display the first level of the classification horizontally.
documents_last	Display document nodes after classifier nodes.
Options Inherited from BaseClassifier
buttonname	The label for the classifier screen and button in navigation bar. The default is the metadata element specified with -metadata.
no_metadata_formatting	Don't do any automatic metadata formatting (for sorting.)
builddir	Where to put the built indexes.
outhandle	The file handle to write output to.	Default: STDERR
verbosity	Controls the quantity of output. 0=none, 3=lots.	Default: 2
