Archive of Items

To start building an Omeka site, a user first needs to add some content building blocks called items.

An Item contains metadata, or descriptive data about that specific things, based on the Dublin Core Metadata Initiative. Items can belong to a collection, be tagged with many keywords, and used in multiple exhibits.

For more information on Working with Dublin Core, see:

Watch this screencast for Building an Archive from Omeka, or continue reading below.
