Harvester Profile Configuration Guide

Harvesting guide

Content from third-party sources can be obtained by using EQUELLA’s harvesting tool that is used to collect learning objects and resources from third-party institutions and upload them automatically to the openEQUELLA repository. Content can be obtained from The Learning Federation using the LORAX protocol, while content from other institutions can be gathered with the OAI (Open Archives Initiative) metadata harvesting protocol.

Content contained in the openEQUELLA Digital Repository can also be accessed by using the OAI protocol.

The purpose of this guide is to provide system administrators with an understanding of the openEQUELLA Harvester Profile tool to enable successful management of harvesting.

Please note that this guide has been developed to best reflect the full capabilities of openEQUELLA and as such may differ in appearance to your own installation.

The openEQUELLA harvester allows content from third-party sources to be collected and uploaded to the openEQUELLA Digital Repository. Content can be obtained from The Le@rning Federation (TLF) using the Learning Object Repository Access and eXchange (LORAX) protocol, while metadata can be gathered with the Open Archives Initiative (OAI) metadata harvesting protocol. Content from other openEQUELLA Digital Repositories can also be collected.
