The Librarian Interface follows Microsoft Windows conventions and draws upon
ordinary knowledge of Windows.
<Break/>
Any part of the screen that you interact with, such as a button or text field,
is called a "control".  At any given time one control, called the "focus", is
highlighted and responds to the keyboard.  Several controls allow you to select
parts that are highlighted in dark blue.  Some controls are greyed out to
indicate that they are disabled.
<Break/>
You can move and left- or right-click the mouse in the usual way.  Many
components also allow you to "drag" them, by clicking and holding the left
mouse button, move them with the mouse, and "drop" them elsewhere by releasing
the button.  Potential drop targets alter their appearance when a component
hovers over them.
<Break/>
You can use the keyboard to type into text fields.  Keyboard alternatives are
available for many controls, indicated by a key name in square brackets -- for
example, [Tab] alters the focus.  The plus sign shows if other keys must be
pressed at the same time.
<Break/>
Exit the Librarian Interface program by choosing "Exit" from the "File"
menu.  Your collection will be saved first.
       <Anchor name="advanced">Advanced Instructions:</Anchor>
To access a menu, hold down [ALT] and press the corresponding letter
(underlined).  For example, for the "File" menu press [ALT] + [F].  To choose an
item, press the corresponding key.  For example, while in the File menu
press [S] to "Save" a collection.

To create a new collection, open the "File" menu and choose "New".  Several
fields need to be filled out -- but you can change their values later if you
need to, in the design view.
<Break/>
"Title" is the text displayed at the top of your collection's home page.  It can
be any length.

      <Anchor name="simple">Simple Instructions:</Anchor>
To open an existing collection, choose "Open" from the "File" menu to get the
Open Collection prompt.  A list of your Greenstone collections appears.
Select one to see its description, and click "Open" to load it.  If you seek a
collection that resides outside Greenstone's "collect" folder, click "Browse"
for a file system browsing dialog.
      <Anchor name="advanced">Advanced Instructions:</Anchor>
In case more than one Greenstone Librarian Interface program is running
concurrently, the relevant directories are "locked" to prevent interference.
On opening a collection, a small temporary lock file is created in its
folder.  Before opening a collection, the Librarian Interface checks to ensure
that no lock file already exists.  You can tell whether a collection is locked
by the colour of its icon: green for a normal collection, red for a locked
one.  However, when the Librarian Interface is exited prematurely the lock file
is sometimes left in place.  When you open such a collection, the Librarian asks
if you want to "steal" control of it.  Never steal a collection that someone
else is currently working on.

  <Section name="huntingforfiles">
    <Title>3.0 Hunting For Your Files</Title>
The Librarian Interface can run in different configurations.  This section only
applies when the "hunt" and/or "mirror" views are enabled.  If these tabs do
not appear, advanced users can enable them by editing the "config.xml" file in
the Librarian Interface installation folder (or, on a multiuser system, in your
home directory's ".gli" folder) to set the values of "workflow.browse" and
"workflow.mirror" to "true".
<Break/>
When using web resources, the Librarian Interface operates in two stages.  This
section describes the first, Hunting, where you browse the Internet for files
of interest. The <Reference target="downloadingfiles">next section</Reference> describes the second stage, Mirroring, where these files can be downloaded.

Access the "Mirror" view by clicking its tab. The top half of the screen shows the downloading controls. The bottom half is initially empty, but will show a list of pending downloading jobs if there are some. 
<Break/>
Files are downloaded into a folder in the workspace tree called "Public
WebCache" (only present when mirroring is enabled), and can be used in all
collections built with the Librarian Interface.  When a collection is open a
second folder, "Private WebCache", appears, which only that collection can access files from.  Files in both these areas are named by their full web
URL.  A new folder is created for each host, followed by others for each part
of the path.  This ensures that each file is distinct.
<Break/>
Use the first of the download configuration controls, "Source URL",  to enter the URL of a
target resource.  If you have come from the "Hunt" view, this field points to
the last page visited.  Use the "Download Depth" control to determine how many
 hyperlinks deep to go when downloading: 0 means follow no hyperlinks and grabs just the
target resource. The depth limit is
ignored when downloading media other than html pages.  Use the "Destination Folder" radio
button control to choose whether the files are cached into the shared public
folder or the private collection-specific folder (if available). Next, there are four checkbox controls which can be set to turn on the specified feature for a specific download. A fifth checkbox control "Automatically remove failed downloads..." does not pertain to a specific download, but instead clears the list of any failed download information, and prevents any future failures from appearing in the list. The final control is a "Download" button, which adds to the download list a new job corresponding to the configuration
settings.
<Break/>
The download list has an entry for each unfinished download.  For each entry, a
central region with several lines of text and a progress bar is flanked by two
buttons.  The text gives details of the task, and updates as the task
progresses, while the bar measures progress.  The "play" triangle on the left
button starts the current task and then changes to a double vertical bar, which
pauses the current download.  The "stop" square on the right button removes the
current download task from the list.  Download tasks are removed from the list
when they finish successfully (ones that fail are controlled by the "Automatically remove failed downloads..." checkbox).
      <Anchor name="advanced">Advanced Instructions:</Anchor>
The <Reference target="preferences">Preferences section</Reference> describes how to establish an Internet connection

identification and password.  The Librarian Interface does not store passwords

The Librarian Interface starts with the Gather view.  To return to this view
later, click the "Gather" tab directly below the menu bar.
<Break/>
The two large areas titled "Workspace" and "Collection" are used to move files
into your collection.  They contain "file trees", graphical structures that
represent files and folders.
<Break/>
Select an item in the tree by clicking it.  (There are other ways; see below.)
Double-click a folder, or single-click the switch symbol beside it, to expand (or collapse)
its contents.  Double-click a file to open it using its associated application
program (see <Reference target="fileassociations">File Associations</Reference>).
<Break/>
The Workspace file tree shows the sources of data available to the Librarian
Interface -- the local file system (including disk and CD-ROM drives), the
contents of existing Greenstone collections, and the public and private
download caches if Web mirroring is enabled.  You can copy and view these files
but you cannot move, delete, or edit them.  Navigate this space to find the
files you want to include in the collection.
<Break/>
The Collection file tree represents the contents of the collection so
far.  Initially, it is empty.
<Break/>
You can resize the spaces by mousing over the grey bar that separates the trees
(the shape of the pointer changes) and dragging.
<Break/>
Beneath is the Status Area, which describes the state of the Librarian
Interface: how many items are selected and what action is requested.  It
reports on the progress of actions that involve files, which can take some time
to complete. The "Stop" button stops any action that is currently in progress. 
<Break/>
Two large buttons occupy the lower right corner of the screen. "New Folder", with a picture
of a folder, creates new folders (see <Reference target="creatingfolders">Creating folders</Reference>). 
"Delete", with a garbage can, removes files. Clicking the Delete button will remove any selected files from the Collection file tree. Alternatively, files can be deleted by dragging them onto the Delete button. 
       <Anchor name="advanced">Advanced Instructions:</Anchor>
To select several sequential items, select the first and then hold down [Shift]
and click on the last -- the selection will encompass all intervening
items.  Select non-sequential files by holding down [Ctrl] while clicking.  Use
these two methods together to select groups of non-adjacent items.
<Break/>
Certain folders -- such as the one containing your own web pages -- sometimes
have special significance.  The Librarian Interface can map such folders to 
the first level of the file tree.  To do this, right-click the desired
folder.  Select "Map", and enter a name for the folder.  To remove an item,
right-click the mapped folder and select "Unmap Folder".

files there (if the source was the Workspace Tree) or move them around within
the collection (if the source was the Collection Tree).
<Break/>
When copying multiple files, they are all placed in the target folder at the
same level, irrespective of the folder structure they occupied originally.
When you copy a second file with the same name into the same folder, you are
asked whether to overwrite the first one.  Respond "No" and the file will not be
copied, but the others will be.  To cancel all remaining copy actions, click the
"stop" button.
<Break/>
Only the "highest" items in a selection are moved.  A folder is higher than its
children.  You cannot select files within a folder and also the folder itself.
      <Anchor name="advanced">Advanced Instructions:</Anchor>
When you add a file, the Librarian Interface searches through the source
folders for auxiliary files containing metadata previously assigned to the
added file and, if it finds one, begins to import this metadata.  As the
operation proceeds, you may be prompted (perhaps several times) for extra
information to match the imported metadata to the metadata sets in your
collection.  This process involves many different prompts, described in the <Reference target="importingpreviouslyassignedmetadata">Importing Previously Assigned Metadata</Reference> section.  For a more detailed

      <Anchor name="simple">Simple Instructions:</Anchor>
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).
<Break/>
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.
<Break/>
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.
<Break/>
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".
<Break/>
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.
<Break/>
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.
<Break/>
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.

Sets of predefined metadata elements are known as "metadata sets".  An 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".
<Break/>
To add a metadata set, choose "Metadata Sets" from the menu bar and select the
"Import Set" action.  A list appears that shows the sets stored in the Librarian
Interface's metadata folder.  Choose one and open it, or click "Browse" to
locate metadata set files stored elsewhere. If the metadata elements have associated value trees, you will be asked whether to import
all values associated with the elements in the set, just those values that make
up the structure of hierarchy-based metadata, or no values at all.
      <Anchor name="advanced">Advanced Instructions:</Anchor>
To install a newer version of a metadata set, simply add it as above.  The
Librarian Interface merges the sets, but does not alter values you have
entered.  You may be asked how to merge certain elements.  For example if the
current set and the one you are importing share a common element (which is
likely if you are installing a new version of a set), you are shown as much
information about the existing and new elements as possible, and asked how to
proceed.  Options include merging the elements, renaming the new one, replacing
the old element entirely, or skipping this element.  When merging two elements
you are confronted with the same options, but this time at the "attributes"
(rather than "elements") level.  You can cancel the import operation at any
time.
<Break/>
The ".mds" files are expressed in XML format.  You can edit an existing metadata
set or create a new one with an ordinary text editor.  If you are starting a
new file, copy the Document Type Definition and be sure to follow it, otherwise
the Librarian Interface will be unable to load the metadata set.  Use of an
XML validator or validating editor is recommended.
<Break/>
To export a metadata set, or part of one (e.g.  its assigned value hierarchy, or
all its values), return to the Librarian Interface and choose "Export Set" from
the "Metadata Set" menu.  You will be asked to select appropriate export
options, and a file to export into.

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.
<Break/>
Next select the metadata element you want to add by clicking its row in the
table.
<Break/>
Type the value into the value field.  Do not use the character "\", as it is
used for constructing hierarchies.  When finished, click "Append" to add the new
value as metadata for the chosen file.  The value immediately appears in the
Metadata table.
<Break/>
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.
<Break/>
When you add metadata to multiple files at once, you will be prompted for confirmation for any files that already have a value for that metadata. You are shown the name of the file in question, the element's
title, previously-assigned values for this element, and the new value.  The
buttons offer different options: "Append" appends the metadata to the file
without altering any existing values; "Append All" adds the new value to all
other files too, without requiring individual confirmation; "Skip File" proceeds to the next file; "Cancel"
undoes any changes and cancels the action.
<Break/>
If you choose metadata that occurs in some of the selected files and click
"Append", it is added to the other files in the selection too.

To update the value of a piece of metadata, first choose the file to which that
value applies, and then the metadata element whose value you want to change.
Your selection appears in the metadata edit controls.  Edit the value field and
click "Replace" to alter the metadata.

The process is the same when updating a folder with child folders or multiple
files, except that when you click "Replace" you are asked what to do with the
other files.  The buttons offer different options: "Replace" replaces any
previous value with the new one; "Replace All" adds the new value in the same
way to all other files; "Skip File" skips the current file and proceeds to the
next; "Cancel" undoes any changes and cancels the action.  You can only update
metadata that is common to all files selected.  For a folder, this means that
all its contents must share the same metadata.

When you remove metadata from a folder, or from several files, you are

<Break/>
Select the files you wish to examine, and from the "Metadata Set" menu choose "Assigned Metadata...".  A window called
"All Metadata", dominated by a large table with many columns, appears.  The
first column shows file names; the rows show all metadata values assigned to
those files.

You can also view the "All Metadata" table by selecting the files you wish to
examine, right-clicking, and choosing "Assigned Metadata...".  If a folder has
been selected, all its child files are included in the table.
<Break/>
When it gets too large, you can filter the "All Metadata" table by applying
filters to the columns.  As new filters are added, only those rows that match
them remain visible.  To set, modify or clear a filter, click on the "funnel"
icon at the top of a column.  You are prompted for information about the filter.
Once a filter is set, the column header changes colour.
<Break/>
The prompt has a "Simple" and an "Advanced" tab.  The Simple version filters
columns so that they only show rows that contain a certain metadata value ("*"
matches all values).  You can select metadata values from the pull-down list.
The Advanced version allows different matching operations: must start with,
does not contain, alphabetically less than and is equal to.  The value to be
matched can be edited to be any string (including "*"), and you can choose
whether the matching should be case insensitive.  Finally, you can specify a
second matching condition that you can use to specify a range of values (by
selecting AND) or alternative values (by selecting OR).  Below this area is a
box that allows you to change the sort order (ascending or descending).  Once
you have finished, click "Set Filter" to apply the new filter to the column.
Click "Clear Filter" to remove a current filter.  Note that the filter details
are retained even when the filter is cleared.

If metadata in a form recognized by the Librarian Interface has been previously
assigned to a file -- for example, when you choose documents from an existing
Greenstone collection -- it is imported automatically when you add the file.
To do this, the metadata must be mapped to the metadata sets available in the
collection.
<Break/>
The Librarian Interface prompts for the necessary information.  The prompt
gives brief instructions and then shows the name of the metadata element that
is being imported, just as it appears in the source file.  This field cannot be
edited or changed.  Next you choose what metadata set the new element should map
to, and then the appropriate metadata element in that set.  The system
automatically selects the closest match, in terms of set and element, for the
new metadata.
<Break/>
Having checked the mapping, you can choose "Add" to add the new metadata
element to the chosen metadata set.  (This is only enabled if there is no
element of the same name within the chosen set.) "Merge" maps the new element
to the one chosen by the user.  Finally, "Ignore" does not import any metadata
with this element name.
<Break/>
Once you have specified how to import a certain piece of metadata, the mapping
information is retained for the collection's lifetime.  To correct any mistakes
during importing, use the metadata set editor described in <Reference target="editingmetadatasets">Editing Metadata Sets</Reference>.

appropriate text (regular expression, file path etc) in the box.  Others are
pull-down menus from which you can select from a given set of values.  Still
others allow multiple selections from a list.  To add a value, select it and

When you have changed the configuration, click "OK" to commit the changes and
close the dialog, or "Cancel" to close the dialog without changing any plugin
arguments.

The plugins in the list are executed in order, and the ordering is sometimes
important.  Two plugins, ArcPlug and RecPlug, are vital to the collection
building process, and are fixed in place at the end of the list (with a

To add an index, type a name for it into the "Index Name" field.  Select which
of the possible information sources to index by clicking the checkboxes beside
them.  The list shows all the assigned metadata elements, as well the full
text.  Having selected the data sources, choose the granularity of the index,
using the "At the level" menu.  Once these details are complete, "Add Index"
becomes active (unless there is an existing index with the same settings).
Click it to add the new index.
<Break/>
To remove an index, select it from the list of assigned indexes and click
"Remove Index".
<Break/>
The default index, the one used on the collection's search page, is tagged with
"[Default Index]" in the "Assigned Indexes" list.  To set it, select an index
from the list and click "Set Default".  To reset it, click "Clear Default".
<Break/>
If advanced searching is enabled (via the Search Types view), the index controls are different.  Each index
is based on just one data source.  There is a new pseudo-data source "allfields" which provides searching across all specified indexes at once.  Levels are not
assigned to a specific index, but apply across all indexes: thus indexes and
levels are added separately.  Indexes are removed in the same way as above, but
the default index can no longer be set -- it is simply the
first index assigned.
<Break/>
To create indexes on all sources, click the "Add All" button. The name of each index will default to the source name. To change the name, select an index, change its details, and click "Replace Index".

The CustomAZList classifier is a special classifier that builds an alphabetical
selection list ("AZList") and allows you to specify the letter ranges.  This
classifier has its own configuration dialogue.  When a metadata element is
selected, the "Ranges" tree automatically becomes populated with appropriate
values.  Expand or collapse the tree as desired.  Select any two values and
click "Merge" to specify a range, or select a previously merged value and click
"Split" to restore the values contained within.  When satisfied with the ranges,
click "OK" to begin processing the documents in the collection.  You can
"Cancel" the dialog without making any changes to the collection.

You can apply a format command to anything in the "Choose Feature" pull-down
list, which includes each classifier and a predefined list of features.  When
you select a feature, there are two types of control.  Some features are simply
enabled or disabled, and this is controlled by a checkbox.  Others require a
format string to be specified.  For these there is a pull-down list ("Affected 
Component") for selecting which part of the feature the string applies to 
(if necessary), a text area ("HTML Format String") for entering the string, 
and a selection of predefined "Variables".  To insert a variable into the 
current position in the format string, select it from the pull-down list and 
click "Insert".
<Break/>
You can specify a default format for a particular component by selecting the
blank feature.  This format is then applied to all applicable features unless
otherwise specified.

There are three "General" options.  If "View Extracted Metadata" is checked, the
various controls dealing with metadata always show all metadata that has been
extracted automatically from documents.  Deselecting it hides this metadata
(although it is still available during collection design, and within the
final Greenstone collection).

If "Show File Size" is checked, the file size is shown next to each file in the Workspace and Collection file trees in the Gather and Enrich views.
<Break/>
The third "General" option is a pull-down list of the various languages that
the Librarian Interface can be presented in.  These correspond to the
dictionaries located in the "classes" folder of the Librarian Interface's
directory.  If you change the dictionary by choosing one from the list, you must
restart the Librarian Interface in order to load the new language strings from
the dictionary.
<Break/>
The Librarian Interface can support different workflows by determining which of
the various view tabs are visible.  Use the "Workflow" tab to customise what
views are available by checking the boxes next to the views that you want to be
available.  Alternatively, use the pull-down list at the bottom to select
predetermined configurations.  Closing the preferences dialog establishes these
workflow settings.  These settings are stored with the collection, not in the
Librarian Interface configuration file.

    <Title>11.0 Metadata Set and Profile Editing</Title>
This section explains how to edit metadata sets used by the Librarian
Interface.  This is the only way to remove a value from the "Previous Values"
tree.  Although you can use the Enrich view to remove a certain value
from a record, the value remains in the value tree.  To remove it (or any
part of the metadata set, including its elements), use the metadata set editor.
<Break/>
The same tool is used to alter the instructions that map metadata from files
imported into the collection to existing metadata sets.  These are called
"importing profiles".
<Break/>
To edit a metadata set or importing profile, choose "Metadata Sets" from the menu
bar and select the "Edit Set" action.

On the left of the "Edit Metadata Sets" dialog is a list showing what metadata
sets and profiles can be edited.  Click one of these and its details will
appear on the right in one or more tables.  Beneath are buttons for adding,
editing or removing the various parts; alongside them is the "Close" button.
Many buttons are greyed out initially, and are activated by selections in the
tables.  Now we describe how to edit sets and elements.
<Break/>
To define a new metadata set, beside "Set" click "Add", fill out the
information requested, and click "OK".  "Namespace" is a short identifier for
the new set (e.g.  "dc" for Dublin Core; "dls" for the Development Library
Subset).
<Break/>
To remove a metadata set, select it in the list on the left and click "Remove".
A confirmation prompt will appear; confirming it <strong>permanently</strong>
removes the set and all associated metadata.
<Break/>
Some information is associated with each metadata set, such as its creator and
creation date.  We call these "attributes" of the metadata set, and you can
alter them.
Beside "Attribute", click "Add" to add an attribute to the selected metadata
set, fill in the requested information -- name, language and values -- and
click "OK".  Each metadata set is considered unique, so for a new metadata set
the pull-down list for the name and value are initially empty.  Beside
"Attribute", "Edit" becomes active when an attribute is selected in the table
and leads to the same dialog as "Add" (except that the current value is already
filled out).  Beside "Attribute", "Remove" becomes active when the attribute is
selected; when clicked the attribute is removed.
<Break/>
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
it.  To add an element, beside "Element" click "Add" and specify the new
element's name.
<Break/>
To remove a metadata element, select it and beside "Element" click "Remove".
This <strong>permanently</strong> removes the element and all metadata
associated with it.
<Break/>
Just as information is associated with each metadata set, information can also
be associated with each metadata element -- metadata about metadata!  Again we
call these "attributes"; Examples are a language-specific name for the element,
its definition, or perhaps a general comment.
<Break/>
You edit the attributes of an element in the same way that you edit the
attributes of a metadata set, explained above.  In this case the pull-down
lists in the add and edit prompts may contain values from the same attribute of
other elements within the set. 
<Break/>
You can also alter the "value tree" for an element, which
contains all the values that have been assigned to it.  You
can "Add" a value whenever an element is selected.  Choose a parent folder
(if any), enter the value and click "OK" to put the
new value in the tree.  You can "Edit" a value that you have selected in the
value tree; click "OK" to commit the changes.  Note that changing the parent
subject will cause the value to be moved to that subject.  You can "Remove" a
value that you have selected in the tree -- but note that this does
<strong>not</strong> remove all metadata referring to this value, and if the
value is still in use it will be restored the next time you save.
<Break/>
Once you have finished changing the metadata set, click "Close".

Double-click the "Importing Profiles" item to see a list of importing profiles
for importing from other collections into this one.  Each profile is named
after the collection to which it applies -- that is, the collection that
documents are coming from.  You can add a profile by clicking "Add" beside
"Profile" and specifying the name of the collection that it should apply to.  You
can remove a profile by selecting it and click "Remove" beside "Profile".
<Break/>
When a profile is selected, its mapping table appears.  Each line gives a
correspondence between a metadata element in the collection that the metadata
comes from, and a metadata element in the collection being constructed.  You
can edit this table.  To add a new mapping, select a source profile, then click
"Add" beside "Attribute".  The standard attribute dialog box appears, except
that the language field is disabled and the "Values" pull-down list contains
all the elements currently available in the collection.  Mappings can be edited
and removed as described above.
<Break/>
Once you have finished changing the metadata importing profile, click
"Close".
