|

| 52 | On the left of the "Edit Metadata Sets" dialog is a list showing what metadata
|
|---|
| 53 | sets and profiles can be edited. Click one of these and its details will
|
|---|
| 54 | appear on the right in one or more tables. Beneath are buttons for adding,
|
|---|
| 55 | editing or removing the various parts; alongside them is the "Close" button.
|
|---|
| 56 | Many buttons are greyed out initially, and are activated by selections in the
|
|---|
| 57 | tables. Now we describe how to edit sets and elements.
|
|---|
| 58 | <p></p>
|
|---|
| 59 | To define a new metadata set, beside "Set" click "Add", fill out the
|
|---|
| 60 | information requested, and click "OK". "Namespace" is a short identifier for
|
|---|
| 61 | the new set (e.g. "dc" for Dublin Core; "dls" for the Development Library
|
|---|
| 62 | Subset).
|
|---|
| 63 | <p></p>
|
|---|
| 64 | To remove a metadata set, select it in the list on the left and click "Remove".
|
|---|
| 65 | A confirmation prompt will appear; confirming it permanently
|
|---|
| 66 | removes the set and all associated metadata.
|
|---|
| 67 | <p></p>
|
|---|
| 68 | Some information is associated with each metadata set, such as its creator and
|
|---|
| 69 | creation date. We call these "attributes" of the metadata set, and you can
|
|---|
| 70 | alter them.
|
|---|
| 71 | Beside "Attribute", click "Add" to add an attribute to the selected metadata
|
|---|
| 72 | set, fill in the requested information -- name, language and values -- and
|
|---|
| 73 | click "OK". Each metadata set is considered unique, so for a new metadata set
|
|---|
| 74 | the pull-down list for the name and value are initially empty. Beside
|
|---|
| 75 | "Attribute", "Edit" becomes active when an attribute is selected in the table
|
|---|
| 76 | and leads to the same dialog as "Add" (except that the current value is already
|
|---|
| 77 | filled out). Beside "Attribute", "Remove" becomes active when the attribute is
|
|---|
| 78 | selected; when clicked the attribute is removed.
|
|---|
| 79 | <p></p>
|
|---|
| 80 | Double clicking on a set in the list on the left will display a list of metadata elements in that set. You can add an element, remove it, and remove values from
|
|---|
| 81 | it. To add an element, beside "Element" click "Add" and specify the new
|
|---|
| 82 | element's name.
|
|---|
| 83 | <p></p>
|
|---|
| 84 | To remove a metadata element, select it and beside "Element" click "Remove".
|
|---|
| 85 | This permanently removes the element and all metadata
|
|---|
| 86 | associated with it.
|
|---|
| 87 | <p></p>
|
|---|
| 88 | Just as information is associated with each metadata set, information can also
|
|---|
| 89 | be associated with each metadata element -- metadata about metadata! Again we
|
|---|
| 90 | call these "attributes"; Examples are a language-specific name for the element,
|
|---|
| 91 | its definition, or perhaps a general comment.
|
|---|
| 92 | <p></p>
|
|---|
| 93 | You edit the attributes of an element in the same way that you edit the
|
|---|
| 94 | attributes of a metadata set, explained above. In this case the pull-down
|
|---|
| 95 | lists in the add and edit prompts may contain values from the same attribute of
|
|---|
| 96 | other elements within the set.
|
|---|
| 97 | <p></p>
|
|---|
| 98 | You can also alter the "value tree" for an element, which
|
|---|
| 99 | contains all the values that have been assigned to it. You
|
|---|
| 100 | can "Add" a value whenever an element is selected. Choose a parent folder
|
|---|
| 101 | (if any), enter the value and click "OK" to put the
|
|---|
| 102 | new value in the tree. You can "Edit" a value that you have selected in the
|
|---|
| 103 | value tree; click "OK" to commit the changes. Note that changing the parent
|
|---|
| 104 | subject will cause the value to be moved to that subject. You can "Remove" a
|
|---|
| 105 | value that you have selected in the tree -- but note that this does
|
|---|
| 106 | not remove all metadata referring to this value, and if the
|
|---|
| 107 | value is still in use it will be restored the next time you save.
|
|---|
| 108 | <p></p>
|
|---|
| 109 | Once you have finished changing the metadata set, click "Close".
