Guest User

You must upload and install the Guest User plugin before installing and activating the Contribution Plugin.

Contribution

The Contribution plugin provides a form to collect stories, images, and other files from the public and manage those contributions in your Omeka site as items. Contributors may share and upload content anonymously, and their information will only be available to site administrators. Other plugins can be integrated into the Contribution form, such as Simple Vocab for creating dropdown menu choices, and Geolocation for inviting users to map their submissions or locations.

Installing and configuring the Contribution plugin requires a few steps. Please read through the Omeka documentation carefully.

See the page on Collecting Community Contributions for additional information on our site’s Contribution Terms of Service and how we configured this plugin for collecting and managing stories, images, and other files from the public.

Dublin Core Extended

Dublin Core Extended provides additional metadata elements that you may find useful to collect in your Contribution collection form. We used this plugin specifically for the ‘Spatial Coverage’ element, which along with the Simple Vocab plugin, allows contributors to submit the location of their contribution.

Simple Vocab

Simple Vocab is a useful plugin for providing predetermined vocabulary for any metadata elements. This plugin allows you to create drop-down menus that replace the usual text box for an element.

We used Simple Vocab to replace the element for “Spatial Coverage” with a list of locations around Charlottesville relevant to the events. When a contributor chooses to fill out the ‘Location’ input in the collection form, they choose from a drop-down list of predetermined terms, set in the Simple Vocab settings. Once the plugin is installed, you can manage your custom vocabulary by clicking on the ‘Simple Vocab’ tab on the left-hand menu in your Omeka dashboard:

Element Types

Used for standardizing date input for contribution submissions (provides a pop out calendar for date selection in the Contribution form).

Derivative Images

Simple Pages

Used to create our About the Archive page. This plugin is useful for creating additional text rich pages for your site, and comes bundled with your Omeka download.

Search by Metadata

The Search by Metadata plugin makes it possible for visitors to your public Omeka site to see a browse page with items that share specific metadata (i.e., all items with ‘UVA Rotunda’ in the Spatial Coverage field). This plugin works very well with the Simple Vocab plugin for controlling metadata vocabulary. See the related Omeka documentation for details on configuring this plugin.

Additional Plugins

We do not currently have the following plugins active on our collecting site, but they may be useful for others.

Geolocation

The Geolocation plugin allows you to assign a location to items in your Omeka site. The locations are displayed on maps on individual items page and on a browsable map of all geolocated items, that you can add to your site’s primary navigation. This plugin also allows you to add a map to your Contribution form, allowing contributors to select locations on a map to submit with their materials.

Exhibit Builder

The Exhibit Builder plugin allows you to develop online exhibits, or special web pages, that combine items from your Omeka archive and may include narrative text. You may find it useful for creating exhibit pages out of collected materials. This plugin is included in your downloaded Omeka installation and does not require a separate download.

Dropbox

The Dropbox plugin allows you to upload multiple files directly into a folder on your server that you can then add in the items admin interface.
