In the section data archiving you were already given a couple of examples of data archives. But what if you were looking for this type of archive yourself? How would you find out which data archives there are? And how would you find research data?
Two frequently used strategies for finding research data are:
- Via directories.
Via directories such as re3data.org(1) you can search for data archives. In Re3data.org you can search by Subject, Content type and Country. In addition, you can select whether you want to search for data archives with a certificate, with data sets that are available via open access or for data sets that have a persistent identifier. Re3data.org and another well-known service, databib.org(2), will be merged.(4)
Subsequently, you can search for the data sets in the data archive of your choice. Each data archive has its own search options.
- Via data portals.
You can also search for data sets via so-called data portals. This allows you to search in multiple data archives at the same time:
- NARCIS(5) allows you to search for data sets which are available in Dutch data archives and repositories.
- A portal which was developed in 2013 is the Surveydata Netherlands portal.(7)
- Via the Data Citation Index(8) you are able to search in the metadata of the data sets for an increasing number of connected data archives(9). Thomson Reuters uses metadata harvesting. She 'catches'all the metadata in the data archives she indexes. The data sets are linked to the primary literature. There are licensing costs involved in using the Data Citation Index.
The data sets of 4TU.Centre for Research Data can be found via the Data Citation Index.(10)
Case metadata as a search key
An in-depth look
Are you interested in searching for data and other information? During the course Professioneel zoeken naar informatie (Dutch)(12) (Professional search for information) VOGIN will discuss this subject in detail.
