Anticipates a number of enhancements including Google-like search, browse by subject, access to duplicates (provides access to all potential duplicates; attempt to discover and remove duplicates during ingest) and automated clustering of subject metadata in the test search interfaces. Discloses deep web resources.

DRIVER is an EU-funded project aiming to facilitate the establishment of repositories in research-based institutions across Europe. It has established a set of guidelines (http://www.driver-repository.eu/DRIVER-Guidelines.html) offering a best practice tool and streamlining repository developments in Europe. Repositories register with DRIVER for harvesting: DRIVER currently provides a search service across around 170 repositories.

DART Europe

/www.dart-europe.eu/basic-search.phpbtopic 

Partnership of research libraries providing European portal for electronic theses and dissertations. Is the European Working Group of NDLTD.

 

National harvesters

The number of national-level harvesting initiatives is growing. They are usually funded either by government or by the national library in each country. Some are still at project/pilot level and funding for a sustainable future is not secure in all cases. The main initiatives (there may well be more in development) are listed below and shown on the diagram.

 

ARROW (Australian Research Repositories Online to the World) Discovery Service

http://search.arrow.edu.au/

Developed by the National Library of Australia, ARROW harvests from 28 university repositories and a further 12 digital collections. 

 

CARL/ARBC Metadata Harvester

http://carl-abrc-oai.lib.sfu.ca/

Canadian Association of Research Libraries. Harvests from 10 university repositories (2 of these are e-theses collections).

 

DRIVER Belgium

http://www.driver-repository.be/

The Belgian harvester built using DRIVER guidelines. Harvests Belgian university repositories.

 

DDF (Danish National Research Database)

http://www.forskningsdatabase.dk/About.html

Government-funded and part of the Danish Electronic Library (DEFF). Harvests OA repositories where present; focused so far mainly on institutional CRISes.

 

e-Ciencia

http://www.madrimasd.org/informacionIDI/e-ciencia/

Madrid region harvester for universities in the region, including UNED (National Distance Education University of Spain) and the CSIC (Spanish National Research Council) repository.

 

Intute Repository Search

http://www.intute.ac.uk/irs

JISC-funded project (until July 2009) developed by MIMAS and UKOLN. Harvests and searches across UK repositories. Developing additional semantic search capabilities including metadata clustering.

 

IRIScotland

http://cdlr.strath.ac.uk/iriscotland/

JISC-funded project (completed 2008) that produced a pilot search service working on 7 Scottish university repositories.

 

Irish National Research Platform

http://www.researchplatform.ie/

Launched mid-2008 as a feasibility project to harvest from Irish institutional repositories. Will also provide the base for 'research assessment, bibliometric analysis and benchmarking'.

 

JAIRO

http://jairo.nii.ac.jp/en/

Japanese national portal developed and maintained by the National Institute of Informatics(NII). Harvests from all Japanese institutional repositories and currently has more than 570,000 metadata records compliant with "junii2", which is the de facto standard used by Japanese repositories and was developed by the NII. Consistent with the Dublin Core Element Set. http://www.nii.ac.jp/irp/en/system/junii2_en_20090213.xls

In addition to JAIRO, some subject-based national harvesters are in service: DML-JP(http://dmljp.math.sci.hokudai.ac.jp/), 'Repository of Archaeological Reports', 'Education Subject Repository', 'Open access and bi-directional repository for medical science', etc.

Aiming to convert Norwegian national metadata to DRIVER standards. Intends NORA to be the single harvesting point for international services wishing to index Norwegian research.

 

OASIS.br

Note added June 2010: see entry below.

 

RIAN

http://www.rian.ie/

Ireland's national portal for OA research is now launched. Called RIAN (Irish for 'path'), this service harvests from seven Irish university repositories and that of the Dublin Institute of technology. it will expand its coverage to other Irish OA providers over time. `the development of RIAN was managed by the Irish Universities Association Librarians' Group and is supported by the Association. It was funded equally by the Universities and the Irish Government's Strategic Innovation Fund which is administered by the Higher Education Authority. 

 

 

SwePub

http://www.ub.gu.se/swepub.se/english/

Swedish national harvester developed by Universities of Uppsala and Gothenburg and the National Library of Sweden. Harvests from institutional publication databases (generally metadata-only records) and OA repositories where available. Provides metadata for harvesting by other services. Aim is to integrate it with the national bibliographic service LIBRIS (http://libris.kb.se). The requirements for this national service have been specified: the beta release is expected at the end of April 2009 and the final release in September 2009.

 

Notes

Google has recently changed the way it indexes repositories since it has dropped support for OAI when it indexes websites. It also appears to miss a considerable proportion of the hidden web. See:

Hagedorn K and Santelli J (2008) Google still not indexing hidden web URLs.  http://www.dlib.org/dlib/july08/hagedorn/07hagedorn.html [Google is 'missing' 55% of records in repositories]

Alma, I remind you that "Busca repositorios" is NOT a harvester (it does not aggregates anything); it is a catalogue of repositories in Spain; it is similar to OpenDoar (which you don´t consider a harvester, right?)

"e-ciencia": please will you include also UNED (National Distance Education University of Spain), which is also aggregated in this regional harvester.

Thanks and kind regards,

alicia
