Value Suggest

The Value Suggest module adds an auto-complete feature to specific properties in a resource template, and draws on controlled vocabularies (see the end of this page for a complete list) to help users fill them out.

Value Suggest appears when a user is editing the metadata of a resource (an item, a piece of media, or an item set) that uses the enabled resource template. It functions as a data type, but works like a modification to a text field: a user can start typing and select a suggestion from the dropdown, or ignore the dropdown and enter in a textual entry manually.

This module also allows any field to be set to suggest values already stored in that property across the entire Omeka installation. These suggested values can be narrowed by only the same property on resources with the same class, or only the same property on resources using the same resource template, to limit the number of suggestions and make them more relevant.

This functionality helps those building an Omeka site encourage consistent metadata input and data compatibility with other databases of records. Note that Value Suggest offers, but cannot require, that users select values from the autosuggest feature. Users will always have the option of creating their own text value instead.

Value Suggest data types can be included in combination with other data types such as URIs in order to encourage interoperable metadata practices to outside databases such as Wikidata.

Add suggestions to a resource template

Value Suggest vocabularies are applied through resource templates. For additional information on resource templates, see the resource template documentation.

  1. From the Resources templates page in the admin dashboard, either add a new template or edit an existing one.
  2. Add the property to which you want to apply the Value Suggest.
  3. Once the property is added to the template, click the pencil/edit icon for that property.
  4. At the bottom of the drawer which opens on the right, open the "Data type" dropdown. Below the standard options, you will see the Value Suggest options. Select the vocabulary you want to use from the dropdown. Note that you can add alternate labels and comments for the property in this drawer.
  5. Click the "Set changes" button at the bottom of the drawer to assign the values to the property.
  6. Save changes to the resource template.

When you click the title of a resource template to see its details, the Value Suggest vocabulary will appear under the Data type table heading.

A red rectangle highlights the fact that the data type for Subject is "LC: Subject Headings"

Adding Value Suggest to resources

When a Value Suggest resource template is used for an item, media, or item set, the designated properties will auto-suggest values from the vocabulary specified in the template.

Users must start typing in the open text box of that specific property to prompt the auto-suggest feature. There may be a slight delay, but a drop-down menu will appear with choices drawn directly from the authority or vocabulary list you have associated with that property. In some cases, your text will search behind-the-scenes values: for example, ROR will display organization names with matching acronyms; ORCID will display researcher names that match an ORCID ID you have entered.

Item property Subject with "fashion" typed in the field. A dropdown menu auto-suggests terms, including "fashion design," which is selected.

Hover over selections in the dropdown menu for a description of that vocabulary.

Item property Material with "lithograph" typed in the field. A dropdown menu auto-suggests terms, including "color lithographs," which is selected. Helper text in a small overlaid window reads, "Lithographs printed in several colors."

After selecting a value, a box containing a URL should appear under the value. This link will direct visitors to a webpage with additional information on the value selected. This box can be removed by clicking the "X".

Item property Work Type with "Fashion Illustrations (layout features)" selected. Below, in red is a hyperlink to Getty Collections, with a small red "X".

Internal suggestions

This module offers the ability to suggest values currently stored in your Omeka installation:

  • Omeka: Property (values of the same property, for example dcterms:creator)
  • Omeka: Property / Resource template (values of the same property that are being used by items that share the same resource template, for example "Base resource")
  • Omeka: Property / Resource class (values of the same property that are being used by items that share the same class, for example dctype:StillImage).

Note that the NDE Termennetwerk vocabularies are now available as a separate module. That module requires Value Suggest to be installed and active.


Some vocabularies appear in multiple languages in the list below: for example, Homosaurus (in English) is listed separately from the Dutch translation of Homosaurus found in the NDE Termennetwerk module. Search the list and refer to the services to see which languages they support. We have indicated languages here for services that serve primarily one (non-English) language.
