EThOS A National OAI and Digitisation Service for e-theses in the United Kingdom Chris Awre EThOSnet Web Services Day June 2009
What is EThOS? EThOS feasibility study, o JISC project to develop a pilot OAI service provider for e-theses o Also tasked with developing a financially viable and sustainable business model EThOSnet project, o JISC project to develop a live service British Library EThOS service o Live since 20 th January 2009 o Six-fold increase in demand
EThOS Toolkit Dual role o Advocate e-theses and how to implement the necessary procedures and technology o Establish a common process that allows an OAI service provider to work over the many varied institutional repositories providing e-theses Information provided by EThOS… o …but also sought from the community
EThOS hub Based on a customised version of EPrints 2 for storing the e-theses Using the ARC harvester The user interface is derived from BLDirect Bespoke development for admin interface Bespoke prototype development of web service submission tool Re-use and modification of existing software saved considerable time and money
Technical architecture
Aggregate and deliver
Technical futures Compound e-theses o EThOS can deal with multiple files, but not when packaged OAI-ORE may assist here SWAP not that helpful Identifiers o Key to persisting relationships across repositories o Current identifiers are unique, but not de- referenceable This will change when EThOS metadata becomes harvestable
Web Services Web Services encompasses many different potential technologies o No fixed agreement on their scope o OAI often considered a web service Focus of this workshop is primarily on SOAP and REST-based Web Services o Current interest – a technology fashion? o Recognising there is a spectrum of uses for these But also… o Why Web Services? o Sharing experiences of use
Web Services & repositories In context, can repositories benefit from using Web Services? o For their own immediate purposes e.g., deposit o For their interaction with other systems o For federated repository services Existing EThOS architecture does not make use of Web Service technologies o Deposit tool prototype not developed further Today is informing EThOS, but hopefully of benefit to repository development generally
