Simple Instructions:
Use the Enrich view to assign metadata to the documents in the collection.
Metadata is data about data -- typically title, author, creation date, and so
on. Each metadata item has two parts: "element" tells what kind of item it is
(such as author), and "value" gives the value of that metadata element (such as
the author's name).
On the left of the "Enrich" view is the Collection Tree. To the right is the Metadata Table, which shows metadata for any selected files or folders in the Collection Tree. Columns are named in
grey at the top, and can be resized by dragging the separating line. Clicking
any row transfers its details to the MetaEdit Controls below. If several files
are selected, black text indicates that the value is common to all of the
selected files, while grey text indicates that it is not. Black values may be
updated or removed, while grey ones can be removed from those that have it, or
appended to the others.
A folder icon may appear beside some metadata entries. This indicates that the
values are inherited from a parent (or ancestor) folder. Inherited metadata
cannot be edited or removed, only appended to or overwritten. Click on the
folder icon to go immediately to the folder where the metadata is assigned.
The MetaEdit Controls at the lower right appear only when a file is selected
from the tree and a row is selected from the table. Use them to update, append,
and remove the metadata value. The value field is for entering or editing the
metadata value. Beside it is a button labelled "..." which, when clicked,
opens a larger editing box. In the buttons below, "Append" assigns the value as
new metadata and adds it to any existing values for the selected element,
"Replace" overwrites the selected existing value with the new one, and "Remove" clears
the selected value. Underneath, labelled "All Previous Values", is the "Value
Tree".
The Value Tree expands and collapses. Usually it is a list that shows all
values entered previously for the selected element. Clicking an entry
automatically places it into the value field. Conversely, typing in the text
field selects the Value Tree entry that starts with the characters you have
typed. Pressing [Enter] auto-completes the typing with the selected value.
Metadata values can be organised into a hierarchy. This is shown in the Value Tree using folders for internal levels. Hierarchical values can be entered using the character "\" to separate the levels. For
example, "Cards\Red\Diamonds\Seven" might be used in a hierarchy that represents a pack of playing cards. This enables values to be grouped together. Groups can also be assigned as metadata to files.
Greenstone extracts metadata automatically from documents into a metadata set
whose elements are prefixed by "ex.". This has no value tree and cannot be
edited, so the edit controls are hidden if such an entry is selected. The
"..." button still serves to expand the value, but the text cannot be edited.
