SWORD Simple Web-service Offering
Repository Deposit
Julie Allinson
25th March 2009, British Library
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
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
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
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
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
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
A lightweight deposit web service can facilitate this transfer of object(s)
Scenario 1
DepositThe depositor can
choose one or more repositories to deposit into
A lightweight deposit web service can facilitate this transfer of object(s)
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
Scenario 2
SWORD AtomPub Profile
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)
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
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
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
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
More Features
No-Op (Dry Run) Verbose Output Client and Server Identity Auto-Discovery Error Documents Nested Service Description
SWORD APP Error Documents
SWORD adds new class of document to AtomPub to allow better error description ErrorContent ErrorChecksumMismatch ErrorBadRequest TargetOwnerUnknown MediationNotAllowed
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
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
SWORD In Use
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
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

OAI-OREObject Re-use and Exchange
Julie Allinson
25th March 2009, British Library
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
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
Key terminology for ORE
Aggregations Web architecture – resource, URI,
representation, link Resource Maps Linked Data / Semantic Web RDF ATOM Serialization
ORE in one sentence
“ORE is a serialization format for describing aggregations of Web resources”
(according to me)
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
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
That’s it.
