Talk outline• Aims

• Background– Discovery– Delivery

• Proof-of-concept

• Demonstrator service

• Issues & Next steps


3

Aims: assist deposit into multiple existing repository services by developing middleware that will aid both discovery of repository targets and delivery of the content


4

Background

• Depot (2007/09) - unmediated eprints repo

• EDINA added a referral service, called Repository Junction, to redirect users to existing IR services.

• Survived by the OpenDepot.org service run by EDINA.

• OA-RJ (2009/11) – to expand on the concept of the Repository Junction

• Initial focus on the discovery aspect; however,

• Concept of data mining for target repo identification lead to broker service.

The Junction API

Suite of three APIs for interacting with the data:/api [primary point of interaction]/cgi/list/ [lists known values - type/content/country/lang/org/net] /cgi/get [used for internal AJAX functions orgs, repos, net]

http://oarepojunction.wordpress.com/junction-api/

•/api can be given a specific locus to deduce repositories (IP address or an ID code) to specify the organisation, or it will deduce a locus based on the calling client.

•The script can be asked to restrict the returned list by repository type (institutional/learning/..) or accepted content (pre-prints/data/thesis/...)

•Data is returned in either JSON, Text, or XML formats

Consider a complete bipartite graph between 2 sets,

where Set A (=3 nodes) passes information to Set B (= 5 nodes) :

Set a

Set b

Total number of edges = 15

Each data provider needs to broker an agreement

with every target repository, and each target repository

needs to authenticate each data provider - this does not scale


8

Consider adding a central node to connect the sets:

Set a

Set b

Set A (=3 nodes) passes information to central node,

Central node passes information to Set B (= 5 nodes),

number of edges = 8

In this structure, each party maintains just one

relationship with a trusted operator


9

Nodes:• 185 repos listed in openDOAR for UK• 200+ publishers listed in SHERPA

Edges:

37,000 or 385

... what are the Global Figures? Researchers are not confined to the UK borders

Proof-of-concept

How a broker model could simplify things:- one consistent deposit process- single sign up for content providers and receivers- building a network of trust

Estimate of the number of broker transferred items during a six month demonstrator service. Data is based upon the number of papers published in journals from the participating NPG portfolio during Jan - June 2010. Data retrieved from PubMed Central and ISI Web of Knowledge.

Issues and dependencies

• Common deposit package for SWORD

• Missing data – provenance/embargo details/ author affiliations

• Licensing – content providers and repos

• Institutional sign-up – federation model?
