From TDL Wiki
With an Institutional Repository hosted by the TDL, your institution can collect, store, preserve, and disseminate digital content – including documents, audio files, images, and datasets – on secure TDL servers.
TDL digital repositories use DSpace, an open-source repository software that allows users to adapt submission workflows to the needs of various user groups. Works within a TDL-hosted Institutional Repository are indexed by commercial search engines, such as Google, and OAI-PMH harvesters such as OAIster. Users can also access materials via RSS feeds and a repository’s own search feature.
