13 | Sometimes you need to see the metadata assigned to many or all files at once -- for instance,
|
---|
14 | to determine how many files are left to work on, or to get some idea of the
|
---|
15 | spread of dates.
|
---|
16 | <p></p>
|
---|
17 | Select the files you wish to examine, then right-click and choose "Assigned Metadata...". A window called
|
---|
18 | "All Metadata", dominated by a large table with many columns, appears. The
|
---|
19 | first column shows file names; the rows show all metadata values assigned to
|
---|
20 | those files.
|
---|
21 | <p></p>
|
---|
22 | Drawing the table can take some time if many files are selected. You can continue to use the Librarian
|
---|
23 | Interface while the "All Metadata" window is open.
|
---|
24 | <p></p>
|
---|
25 | When it gets too large, you can filter the "All Metadata" table by applying
|
---|
26 | filters to the columns. As new filters are added, only those rows that match
|
---|
27 | them remain visible. To set, modify or clear a filter, click on the "funnel"
|
---|
28 | icon at the top of a column. You are prompted for information about the filter.
|
---|
29 | Once a filter is set, the column header changes colour.
|
---|
30 | <p></p>
|
---|
31 | The prompt has a "Simple" and an "Advanced" tab. The Simple version filters
|
---|
32 | columns so that they only show rows that contain a certain metadata value ("*"
|
---|
33 | matches all values). You can select metadata values from the pull-down list.
|
---|
34 | The Advanced version allows different matching operations: must start with,
|
---|
35 | does not contain, alphabetically less than and is equal to. The value to be
|
---|
36 | matched can be edited to be any string (including "*"), and you can choose
|
---|
37 | whether the matching should be case insensitive. Finally, you can specify a
|
---|
38 | second matching condition that you can use to specify a range of values (by
|
---|
39 | selecting AND) or alternative values (by selecting OR). Below this area is a
|
---|
40 | box that allows you to change the sort order (ascending or descending). Once
|
---|
41 | you have finished, click "Set Filter" to apply the new filter to the column.
|
---|
42 | Click "Clear Filter" to remove a current filter. Note that the filter details
|
---|
43 | are retained even when the filter is cleared.
|
---|
44 | <p></p>
|
---|
45 | For example, to sort the "All Metadata" table, choose a column, select the
|
---|
46 | default filter setting (a Simple filter on "*"), and choose ascending or
|
---|
47 | descending ordering.
