38 MAKING GREENSTONE COLLECTIONS
Appending New Metadata
Adding Previously Defined Metadata
example is the Dublin Core metadata set. When you add a metadata set to
your collection, its elements become available for selection. You can have
more than one set; to prevent name clashes a short identifier that
identifies the metadata set is pre-pended to the element name. For
instance the Dublin Core element Creator becomes "dc.Creator".
Metadata sets are stored in the Librarian Interface's metadata folder and
have the suffix ".mds".
To control the metadata sets used in a collection, use the "Metadata Sets"
entry on the Design view.
We now add a metadata item -- both element and value -- to a file. First
select the file from the Collection file tree on the left. The action causes
any metadata previously assigned to this file to appear in the table at the
right.
Next select the metadata element you want to add by clicking its row in
the table.
Type the value into the value field. Use the "|" character to add structure,
as described in The Enrich View. Pressing the [Up] or [Down] arrow keys
will save the metadata value and move the selection appropriately.
Pressing [Enter] will save the metadata value and create a new empty
entry for the metadata element, allowing you to assign multiple values to
a metadata element.
You can also add metadata to a folder, or to several multiply selected files
at once. It is added to all files within the folder or selection, and to child
folders. Keep in mind that if you assign metadata to a folder, any new
files in it automatically inherit the folder's values.
To add metadata that has an existing value, first select the file, then select
the required value from the value tree, expanding hierarchy folders as
necessary. The value of the selected entry automatically appears in the
Value field (alternatively, use the value tree's auto-select and autocomplete
features).
The process of adding metadata with already-existing values to folders or
multiple files is just the same.
