2. Sharing research data
Why?
 It’s expected by research funders, journals, professional organizations and
research evaluators
 Because of scientific integrity: reproducibility of results
 Because of re-using results: data-driven science
 You benefit from it: increases your visibility and enhances the trustworthiness of
your research
How?
 On request
 Personal website
 Publishing / archiving in a repository
International Open Access Week

3. Re-using research data
To be re-used, data should be
 Findable: DOI; metadata (to allow discovery)
 Accessible: ≠ open access; licenses to use; to humans and machines
 Intelligible, assessable: metadata (to allow understandability)
 Interoperable: combining across multiple sources
 Preserved: long-term availability

4. 3TU.Datacentrum #1
 Findability + citability: 3TU.DC assigns DOI’s; discovery metadata are
mandatory; data sets are indexed by DataCite, Google, Data Citation Index
 Accessibility: 3TU.DC = open access; embargo’s (6 months) are allowed
 Intelligible, assessable, interoperable: up to the researcher
 Preservation: 3TU.DC has quality mark Data Seal of Approval

6. DOI’s and OpenML #1
 DataCite Netherlands : assigns and distributes DOI’s on behalf of DataCite
to research organizations and data centers in NL
 Organizations can register DOI’s for its objects by applying for an account
at DataCite Netherlands
+ Objects need to be persistent, long-term available
+ Objects are preferably open access; restricted access is allowed
+ Objects should be citable (metadata added)
+ Objects must have a public landing page

7. DOI’s and OpenML #2
 Organizations must ensure maintenance and supply of metadata
 A contract will be signed to ensure the abovementioned points, after that
the organization will receive its own DOI prefix
 Costs: € 1000,- (once-only, subject to changes)
 Creating DOIs: manually via web forms ↔ uploading xml resources files
