SWORD v2.0: Deposit Lifecycle :
SWORD is a hugely successful JISC project which has kindled repository interoperability and built a community around the software and the problem space. It explicitly deals only with creating new repository resources by package deposit a simple case which is at the root of its success but also its key limitation. This next version of SWORD will push the standard towards supporting full repository deposit lifecycles by using update, retrieve and delete extensions to the specification. This will enable the repository to be integrated into a broader range of systems in the scholarly environment, by supporting an increased range of behaviours and use cases.
