The document discusses SWORD, a protocol for depositing content into repositories. It aims to lower barriers to deposit by providing a standard mechanism. SWORD is based on the Atom Publishing Protocol and supports depositing packages and mediated deposit. Implementations exist for repositories like DSpace, EPrints and Fedora, as well as client tools. The document provides an overview of how SWORD works and some use cases.

1. SWORD Simple Web-service Offering Repository Deposit Julie Allinson 25th March 2009, British Library

2. SWORD Quick Introduction Vision: “lowering barriers to deposit” Simple Web service Offering Repository Deposit Aims to provide a standard mechanism for ‘doing deposit’ into repositories JISC funded project started 2007, continuation funding for SWORD 2 from June 2008

3. What is it? A lightweight protocol for deposit A profile of the Atom Publishing Protocol Implementations of SWORD in IntraLibrary, Fedora, DSpace and Eprints repositories SWORD clients – web-based, desktop, MS Office plugin, Facebook, widgets

4. Motivations – why? no standard interface for tagging, packaging or authoring tools to upload objects into a repository no standard interface for transferring digital objects between repositories no way to deposit into more than one repository with one ‘click’ no way of initiating a deposit workflow from outside a repository system

5. The Project Partners SWORD partners: UKOLN, University of Bath and University of York (Project Management) – Adrian Stevenson & Julie Allinson University of Aberystwyth (DSpace, Fedora, & clients) – Stuart Lewis, Neil Taylor, Glen Robson, Richard Jones University of Southampton (EPrints) – Les Carr, Seb Francois Intrallect (IntraLibrary) – Sarah Currier, Andrew Robson, Martin Morrey Jim Downing – standards development

6. Use Cases Deposit from a Desktop/Online tool Multiple deposit - e.g. deposit to institutional and (mandated) funders’ repository with one action Machine deposit - e.g. automated deposit from a laboratory machine Migration/transfer - e.g. to a preservation service Mediated deposit - e.g. deposit by a nominated representative, to additional repositories

7. Scenario 1 A lightweight deposit web service can facilitate this transfer of object(s) Librarian L completes the deposit through the repository interface id Librarian L invokes deposit of a surrogate into arxiv.org Deposit id Author A deposits via an easy-deposit desktop application into the institutional repository's mediated deposit queue

8. Scenario 2 A lightweight deposit web service can facilitate this transfer of object(s) Deposit The depositor can choose one or more repositories to deposit into A depositor is required to submit to a Research Council repository, but they also wish to deposit into their institutional repository and a relevant subject repository

9. SWORD AtomPub Profile

10. Standards WebDAV (http://www.webdav.org/) JSR 170 (http://www.jcp.org/en/jsr/detail?id=170) JSR 283 (http://www.jcp.org/en/jsr/detail?id=283) SRW Update (http://www.loc.gov/standards/sru/) Flickr Deposit API (http://www.flickr.com/services/api/) Fedora Deposit API (http://www.fedora.info/definitions/1/0/api/) OKI OSID (http://www.okiproject.org/) ECL (http://ecl.iat.sfu.ca/) ATOM Publishing Protocol (http://www.ietf.org/htmlcharters/atompub-charter.html)

11. AtomPub “ the Atom Publishing Protocol is an application-level protocol for publishing and editing Web resources” benefits supports many of our parameters and requirements, in particular file deposit it already exists and has growing support it is well-used in popular applications it has an extension mechanism good fit with the Web architecture drawbacks / risks too much of a retrofit? it is designed for a single package/file OR an atom document – this means that we need to package up metadata and files

12. SWORD AtomPub Profile SWORD profile builds on AtomPub Provides extensions, constraint relaxations and enforcements when: Clients post compound resources (zip,tar) Mediated deposit required Workflows involved SWORD compliance does not preclude AtomPub compliance

13. SWORD APP Package Support AtomPub uses MIME to describe resources SWORD supports accepting MIME types, but Inadequate for compound types e.g. Zip, tar METS, SCORM, MPEG21, DIDL packages SWORD extends AtomPub: sword:acceptPackaging element Value taken from SWORD package types Developing area

14. SWORD APP Mediated Deposit SWORD deposit client user may not be owner of resource SWORD allows clients to set a HTTP header: X-On-Behalf-Of Assumes trust between owner and mediating user Future development could explore OAuth for creating trust relationships

15. More Features No-Op (Dry Run) Verbose Output Client and Server Identity Auto-Discovery Error Documents Nested Service Description

16. SWORD APP Error Documents SWORD adds new class of document to AtomPub to allow better error description ErrorContent ErrorChecksumMismatch ErrorBadRequest TargetOwnerUnknown MediationNotAllowed

17. SWORD Profile of AtomPub Protocol Operations Retrieving Service Document Listing Collections Creating a Resource Editing/Deleting resource – not part of SWORD, optional Service Documents new elements: version, verbose, noOp, maxUploadSize, collectionPolicy, mediation, treatment, acceptPackaging, service increasing requirement for persistent Atom Entry Documents

18. How it Works Issue HTTP requests (GET, POST) from client to SWORD interface GET Service Document (explain/discover) POST ATOM document or file/package to collection URI HTTP response and ATOM document is returned HTTP basic authentication should be supported

19. SWORD In Use

20. Implementations Repository implementations DSpace EPrints IntraLibrary Fedora Client implementations command-line, desktop and web clients Facebook Client Deposit from within MS Word & Powerpoint Feedforward / FOREsite and others Java, PHP and .NET libraries

21. Web Interface

22. Fedora deposit

24. Validation

25. SWORD in use In addition to the case study implementations: Feedforward has already implemented ICE project is looking at SWORD DSpace and EPrints installations already exist Microsoft eChemistry work OAI-ORE - FOREsite work more are planned NISO activity around deposit Collaberation with Nature Publishing Group possible York – funded project around SWORD

27. OAI-ORE Object Re-use and Exchange Julie Allinson 25th March 2009, British Library

28. ORE background commenced October 2006 stands for ‘Object Reuse and Exchange’ falls in the remit of the Open Archives Initiative (creators of OAI-PMH) funded by the Mellon Foundation, with support from the National Science Foundation in the U.S. international focus and lots of interest a 2 year project, not the answer to all our problems ended September 2008

29. ORE Results Primer – in heavy use for the presentation! User Guides Resource Map implementation in ATOM, RDF/XML, RDFa, HTTP Resource Map Discovery Specifications – Abstract Model and Vocabulary Tools and additional resources

30. Key terminology for ORE Aggregations Web architecture – resource, URI, representation, link Resource Maps Linked Data / Semantic Web RDF ATOM Serialization

31. ORE in one sentence “ ORE is a serialization format for describing aggregations of Web resources” (according to me)

32. Relationship to OAI-PMH OAI-ORE is NOT a replacement for OAI-PMH OAI-PMH will continue to exist as one approach to interoperability OAI-PMH metadata-centric OAI-ORE will complement with richer functionality, when this is desirable OAI-ORE is resource centric

33. An example The ForeSite toolkit “ Libraries for constructing, parsing, manipulating and serializing OAI-ORE Resource Maps” Demonstrator created Resource Maps of journals in JSTOR, delivered as ATOM documents via SWORD DSpace interface

36. That’s it.
