Visible elements¶
Visible elements enables an administrator to “hide” specific fields in the database from the public (i.e., unauthorized users, or users who are not logged in). It also allows administrators to hide digital object metadata (such as file size, name, upload date, etc) for uploaded or linked content, and related Physical storage information.
To access the visible elements menu, click on the 
Admin menu in the main menu located in the
header bar and select “Visible elements” from the
drop-down menu. Each visible elements area will appear collapsed when
the page first loads - click on one of the areas to expand it and view the
available fields listed below.
Each visible elements area includes a list of fields with
check boxes next to them. When an element’s checkbox is 
checked,
that element will be VISIBLE to public users. When it is 
unchecked,
it will NOT be visible to public users (e.g. those not logged in).
Important
ALL authenticated users, from contributers to adminstrators, will be able to see those elements hidden from the public via the hidden elements module. If you are logged in, the Visible Elements module is not in operation.
Below you will find a brief outline of each Visible elements area:
- Hide or show the login button
- Hide or show Information area headers
- Hide or show metadata fields
- Hide or show digital object metadata fields
- Hide or show Physical storage

Hide or show the login button¶
With the release of 2.5, an administrator can hide the login button for public users. The default setting allows the login button to be visible to all users. To change this so that the login button is hidden to public users, an administrator can click the Global section of Visible Elements and uncheck the login button. Click “Save”, and exit Visible Elements. The login button will still be visible for authenticated (i.e. logged in) users, but hidden for unauthenticated users.
Note that the login screen can be accessed by adding ‘user/login’ at the end of the site URL.
Hide or show Information area headers¶
AtoM archival description data entry templates are based on international and national content standards for description - more information on the standards currently supported in AtoM can be found here: Descriptive standards.
Most content standards are organized into sections or areas. In AtoM, these are expressed in the view and edit pages as information areas. Information areas appear on view pages and edit pages of any standards-based description template in AtoM, and group related fields based on the organization of elements of description in ICA (or other supported) descriptive standards. They are comprised of a number of fields in the body of the information area, and an area header, whose name is drawn from the related area or section of the standard upon which the descriptive template is based.
While these area headers are useful to archivists working with content standards for archival description, they may not be meaningful to public users. As of AtoM 2.1, an administrator can now hide the various area headers for the RAD and ISAD templates.
To hide an area header from public view, simply uncheck the checkbox next to the header name. Remember to click “Save” in the button block at the bottom of the page when you are finished.
For illustration, below is an example description, displayed using the
ISAD template, with all
area headers visible (i.e. all check boxes
checked):
Here is the same description with all area headers
hidden (i.e. all check boxes unchecked):
Hide or show metadata fields¶
Within the ISAD and RAD templates for archival descriptions, specific fields can also be hidden from public users if desired.
The names of each field available in the ISAD and RAD elements areas are taken directly from field names in AtoM’s data entry templates - which are themselves drawn directly from the related content standards. For specific information on each field, see: Data entry / templates.
An authenticated (logged-in) administrator can check the
checkboxes to reveal the field, while an unchecked box hides
the field. To review which fields can be hidden from the public, select the
ISAD template and /or the RAD template as applicable. Whether you hide/show
elements from the ISAD or RAD area depends on which
default template you are using.
When you have made your changes, remember to click “Save” in the button block at the bottom of the page.
Important
Elements (e.g. fields) that are hidden via the Visible elements module will not be visible to public users in the interface. However, the data will still be contained in the EAD XML download available to end users! Note that physical storage information, described below, is different - because location information can be a security concern for some users, when physical storage information is hidden via the Visible elements module, it is also removed from the EAD XML export for public users.
For more information on EAD XML export, see: Export XML
Hide or show digital object metadata fields¶
In AtoM, when a digital object is uploaded and associated with an archival description, a new information area will appear at the bottom of the description with metadata about the associated digital object:
An administrator can choose to hide some or all of these fields from unauthenticated (e.g. not logged in) users via the Visible elements module.
In the Digital object metadata area, check
a field to make it visible to public users, or uncheck it to
hide the field from public users.
When you have made your changes, remember to click “Save” in the button block at the bottom of the page.
For more information on uploading digital objects in AtoM, see: Upload and manage digital objects.
Hide or show Physical storage¶
Administrators can select whether Physical storage information is visible to
unauthorized (not logged-in) users or not by clicking on Physical storage area, and
checking or unchecking the Physical storage button.
When you have made your changes, remember to click “Save” in the button block at the bottom of the page.
Note
If physical storage is hidden to unauthorized users, the physical storage information will also be missing from exported EAD XML file, if exported by a non-authenticated user. For more information on export and physical storage, see:
