3. Linking Data in ScienceDirect The Past Supplementary data Entity links to databases The Present Some considerations PANGAEA-type linking A Future Getting even closer connected 3

4. The Past (supplementary data) Raw research data delivered as supplementary data Available for limited number of data set types / formats Data distributed over multiple articles and publishers Format frozen in time – not maintained for preservation Only available for smaller data sets (at most few 10 MBs) Limited access due to use of existing publishing platforms Data and article remain nicely coupled / packaged Supplementary data always being peer-reviewed 4

5. The Past (entity linking - manual) Authors manually identify (and tag) entities that are mentioned in articles and of which associated data is present (or registered) in databases, like GenBank, MINT, Uniprot, PDB, CCDC,... Very accurate and unambiguous However, requiring author effort Publisher takes care of actual linking Reciprocal linking usually taken care of 5

6. The Past/Present (entity linking – automatic) Sometimes automatically (e.g., NextBio and Reflect) Easily extendable to new / other entities Works retrospectively on older content Does create recall / precision errors 6

7. The Present (some considerations) STM, Brussels Declaration, June 2006:... believe that, as a general principle, data sets, raw data outputs of research, and sets or subsets of that data should wherever possible be made freely accessible... Data sets should be freely accessible – at publisher? Scientists prefer independent data repositories Need for single domain-specific coordination Huge costs for maintenance and preservation Proper deposit mechanism needed Through publisher? Extra overhead vs. ease of use Enforcing deposit prior to publication If community-supported, surely a possibility Data set standardization is needed for optimal use 7

8. The Present (more considerations) Scientist needs the combination of formal publication record and the raw data sets To get optimal interoperability, close collaboration between publisher and data set repositories needed Publisher should enable and support raw data sets Submission: enforce if supported by community Discoverability: interconnect article with data sets Reciprocal linking at deepest level possible PANGAEA-type linking Data feeds from publisher to repositories? Managing large amount of data set repositories? DataCite as single discussion partner 8

9. The Present (PANGAEA linking) 1.Author submits article to publisher 2.Author submits data set to repository 3.At article publication, repository links article DOI to associated data set DOI, creating actual connection 4.User sees link to ScienceDirect from PANGAEA 5.User sees link to PANGAEA from ScienceDirect: 9 SD Server USER SD Article PANGAEA Server link articles data + associations

10. PANGAEA links to ScienceDirect 10

11. ScienceDirect links to PANGAEA 11

12. A Future (tighter interoperability) Not just a link to / from data and journal article But provide integrated experience for scientist Single page (environment) with data and article 12 SD Server USER SD Article Supplementary Data Server articles data sets

13. A Future (tighter interoperability) Not just a link to / from data and journal article But provide integrated experience for scientist Single page (environment) with data and article Some users prefer it other way around; so also offer: 13 Data Set Server USER Data Set Article Server data sets articles

14. A Future (inline supplementary data) 14

15. A Future (inline supplementary data) 15 Structures submitted as supplementary data files (MOL files) Displayed inline through Reaxys application / service

17. Presented by: IJsbrand Jan Aalbersberg Hannover, DataCite Meeting Date: June 8, 2010 Creating the best User Experience by integrating Data with Articles

18. Presented by: IJsbrand Jan Aalbersberg Hannover, DataCite Meeting Date: June 8, 2010 Creating the best User Experience by integrating Data with Articles requires close collaboration between data set repositories and publishers
