The DSpace-based DataDOI repository is a platform for persistent storing of research data. If no other suitable environment that would ensure the storing of data (e.g. PlutoF or some other) can be found, the data are entered into Datadoi, provided with a DOI and interfaced via DataCite indexes to other similar data elsewhere. The preservation and access to the data is from then on guaranteed by the owner of the repository, the University of Tartu Library. Updates, conformity to standards, and exchange of data are guaranteed as well. The target group consists of single researchers and smaller subunits/work groups at the UT and outside.
The PlutoF platform allows web-based entering, viewing and complementing of natural sciences data. PlutoF is suitable for storing the data on biosystematics, ecology, biodiversity, etc., from field work data up to molecular analyses. The data stored on the PlutoF platform can be made accessible for the public over the Internet. The system allows publication of the stored data by using the DOI system.
The Center of Estonian Language Resources (CELR) creates and manages an infrastructure that makes the Estonian language digital resources (dictionaries, corpora – both text and speech –, various language databases) and language technology tools (software) available to everyone working with digital language materials.
CELR registers allow the adding of DOIs to their language resources. Referring to the DOI of a certain collection of language data in other publications makes the data scientifically more trustworthy and enables more precise gathering of information about the usage of the collections as research resources.
In the DataCite MetaData search, these language resources are best found with the key word 'Estonian language', and more precisely, using the filter: datacentre -> ESTDOI.KEEL on the left-hand menu.
