Repository harvesters

Repository harvesters aggregate metadata from repositories in order to support discovery, analysis and reuse of content. They generally require that repositories are OAI-PMH compliant.

There are a number of network services at the international, national, and regional levels that aggregate metadata to support discovery, analysis and reuse of content in repositories. The services differ based on their objectives and scope, but they all harvest metadata (and sometimes full text) from repositories in order to improve discovery of content. Depending on what type of repository you maintain, you will want to ensure that your repository is being harvested by one or more of these services.
