  2. Agenda • Introduction • BASE • DOI pretest • Conclusions

  3. Introduction • Metadataqualityhasimproved in repositoriesthankstointiatives like COAR, DINI, OpenAIREandothers • Need for Plan S compliance will initiatefurtherimprovements • But whatistherelevanceof IRs for OA discovery?

  4. Introduction • Crossrefhasbecometheprimarysourceforjournalarticles • The numberof Gold OA journalarticleshasincreasedbecauseoffinancing APCs • Do we find thosearticleson IRs?

  5. Introduction • Analysingfrequencyanddistributionof DOIs in BASE index • Pretest: Analysing DOIs ofOpenAPCdataset(OA journalarticles, whichhavebeenfinancedbyfunders, academicinsititutions, libaries, …) in BASE index

  6. Agenda • Introduction • BASE • DOI pretest • Conclusions

  7. BASE developmentsince 2004

  8. Global heatmapofdocuments on repositories

  9. BASE backgrounddevelopmentfordataanalysis Access status Licence Normalization Migration Open Source System Multi-Node System Admin- Database Production Start BASE 2020 2001 2015 2016 2011 2009 2019 2007 2004 Storing Repository Metadata Storing Harvesting Profiles Starting API Implementation Storing Index Facets

  10. Example 1: Documents per repository type in Germany

  11. Example 2: Metadataquality in German repositories (doc lang, doc OA status)

  12. Example 3: Metadataquality in German repositories (doclicense, publication type)

  13. First insights • About 27% of all records in BASE arejournalarticles (exactnumbercannotbedeterminedbecauseoflackingmetadata) • Share differsfromcountrytocountry • Providing comprehensiveand valid information on OA statusandlicenseinformationis still a challenge

  14. Agenda • Introduction • BASE • DOI pretest • Conclusions

  15. Basic questions • Howmany DOIs are in the BASE index? • Howmany DOIs oftheOpenAPCdatasetcanwe find there? • HowmanyOpenAPCs-DOIs do we find on IRs?

  16. First results • Out of 149,8 milliondocumentsand 7,175 sourcesthereare 43.051.773 DOIs indexed in BASE • Top ten: Data Cite(15,1 mill.), PubMed Central (3,3 mill.), DOAJ (2, 8 mill.), HighWire Press (2,4 mill.), Elsevier SD (1,3 mill., only OA articles via Crossref), ), Zenodo(1 mill.), ArXiv (822 k), ETH e-periodica, HAL, Dara

  17. Distribution of DOIs onrepositorytypes in BASE

  18. First resultsforOpenAPCdataset • Out of 78,264 OpenAPC-DOIs 67,614 areindexed in BASE • Top ten: PubMed Central (42,3 k), DOAJ (24,8 k.), DataCite (17,8 k), Elsevier SD (11 k), PLOS (8,1 k), Frontiers (5,1 k), MPG Pure (3,9 k), Oxford Univ. Research Archive (3,7 k), Imperial College (3,1 k), CCSD Articles HAL (2,9 k)

  19. Distribution ofOpenAPC-DOIs on repositorytypes in BASE

  20. Agenda • Introduction • BASE • DOI pretest • Conclusions

  21. Conclusions • Nearlythe half ofOpenAPC-DOI sample canbefound on IRs • PMC, DataCiteand DOAJ havethegreatestshares on theOpenAPC-DOI sample • The firstacademicinstitutions (MPG, Oxford, Imperial College) arebecoming relevant forthediscoveryof Gold OA journalarticles

  22. Conclusions • More academicinstitutionshavetomakestrongereffortstolist Gold OA journalartciles on theirrepositories / CRIS • Need forworkflowstogetarticledatafrom transformative agreementsintorepositories
