Data access

Swepub is a service that harvests scientific publication metadata from the institutional repositories of Swedish higher education institutions (HEIs) and research organisations.

The Swepub metadata is accessible for end users via the Swepub search servicelänk till annan webbplats and Swepub Analysislänk till annan webbplats and is available for free to harvest or to access through the protocols OAI-PMH and SRU. We have also developed a lightweight API, called Xsearch, that accesses the data through HTTP in a simple and straightforward manner. The metadata is available as data dumps as well.

OAI-PMH

The data is exactly as we receive it from the data providers without any data manipulation.

Update frequency: Every night. Some of the data providers support selective harvesting and others perform a total reload every night. As a consequence the datestamps will vary.

SRU

SRU is an XML-based protocol for searching:

Xsearch lightweight API

Xsearch is a http-based lightweight API for accessing data in many different formats. Currently we provide support for the MARC-XML, Dublin Core, JSON, RIS, MODS and RDF formats.

Data dumps

In order to facilitate the reuse of Swepub we provide database dumps. Data dumps are available both from the Swepub search servicelänk till annan webbplats and from Swepub Analysislänk till annan webbplats via ftp.

Data dumps from Swepub search service

All data is available both in original format and in the deduplicated variant that corresponds to what is searchable in swepub.kb.se. The list below contains the data dumps that are available via FTP from the Swepub search service.

Update frequency: Every night.

Data dumps from Swepub Analysis

Listed below are data dumps available via ftp from Swepub Analysislänk till annan webbplats (English name for Swepub för analys och bibliometrilänk till annan webbplats - the Swedish bibliometrics service based on aggregated publication records from Swedish repositories delivered via OAI-PMH). These dumps have been saved for the purpose of retreival of historical data.  

Update frequency: Swepub analysis has not been updated and reindexed since 2017.

Available data dumps

Swepub search service

The dumps are formatted as OAI-PMH "ListRecords"-responses with Swepub-modified mods as metadata format (see passage OAI-PMH above). For the deduplicated data a repeatable non-standard element, <identifier2>, in the OAI-PMH record-header is used for listing the identifiers in a duplicate tuple.

Swepub analysis

The following ftp-address leads you to an index page containing the Swepub Analysis data dump files based on a complete export of all posts from all years together with all available fields. Apart from a file with the full data dump the index page also contains smaller files divided into years.
