APIs and machine-readable metadata records
FSD metadata records in DDI 2.0
FSD's data descriptions are available online as DDI 2.0 XML files (compatible with DDI 2.1). The XML files are machine readable. Please see our data catalogue for human readable HTML versions and PDF codebooks. You will find a link to the DDI 2.0 XML file at the end of each study record.
Links to the XML data descriptions in Finnish and English follow the pattern shown in a table below. <STUDYNUMBER> is an identification identifier given by the data archive, for example FSD2653.
For easy download, the descriptions are also available as zip packages. The packages contain the DDI record for all datasets for which FSD is the originating archive.
The packages contain all information available in that language. Note that there is no one-to-one correspondence between language versions. English metadata may lack variable-level information. A few datasets that have been described only in Swedish can be found in the Finnish catalogue.
The packages are updated whenever our web catalogue is updated. The catalogue does not in general change very often so dowloading the zip packages once a week should keep your records sufficiently up-to-date.
List of direct URIs to individual DDI records are available as text files:
OAI-PMH Server Kuha
FSD's study descriptions are harvestable in DDI Codebook, OAI Dublin Core, and EAD3 formats through Kuha2, OAI-PMH metadata server . Kuha2 server provides access to variable level metadata and language translations. It generates EAD and DC formats from FSD's DDI metadata. The development of the server software was initiated by CESSDA SaW project and has continued as an open source project led by FSD.
More infomation available in Kuha2's documentation .
Kuha1 is closed (October 28, 2021). Switch your harvesting services to use Kuha2.
