  1. Data Citation Service status and first experiences ESGF 2018, Washington 05.12.2018 M. Stockhause, M. Lautenschlager German Climate Computing Center (DKRZ)

  2. CMIP6 Citation Service Evolving CMIP6 data gets citable (requested by WGCM-CMIP6) CMIP6 data citation concept: DKRZ hosts the repository, service package, and the landing page ESGF provides the data access CMIP6 data citations use DataCite DOIs issued by DKRZ on behalf of the ESGF; publisher is the ESGF. Stable citation reference with version information to identify data status and ESGF support filtering for version ranges: Authors (YYYY): Title. Version YYYYMMDD. Earth System Grid Federation. DOI. Voldoire, Aurore (2018). CMIP6 simulations of the CNRM-CERFACS based on CNRM-CM6-1 model for CMIP experiment 1pctCO2. Version 20180626. Earth System Grid Federation. https://doi.org/10.22033/ESGF/CMIP6.3712 Stockhause & Lautenschlager: Data Citation Service 2 ESGF 2018, 05.12.2018

  4. CMIP6 Citation Service Relations (1) CMIP6 Relations: ESGF Index Node for data availability; URL published for machine-access CoG for data reference display; link in DB ES-DOC / furtherInfoUrl for data reference display with source NetCDF file header input4MIPsdata reference Other Relations: DataCite: Metadata and DOI registration Scholix / CrossRef for data usage in literature PCMDI s publication hub and ESGF Dashboard for integration of data usage in literature OpenAire (OAI server) / Google Dataset Search for dissemination of citation information IPCC AR6 and IPCC DDC, e.g. AR6 data references 4 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018

  5. CMIP6 Citation Service Relations (2) Google Dataset Search https://toolbox.google.com/datasetsearch: Based on schema.org standard JSON-LD snippet in HTML meta section Google crawls pages + extracts information <script data-react-helmet="true" type="application/ld+json" nonce="777a5391-f6c7- 4b5f-bbcd-d22b2dc7e9fc">{"@context":"http://schema.org","type": "Dataset", "provider":{"@type":"Organization","name":"World Data Center for Climate (WDCC) at DKRZ","url":"https://cera-www.dkrz.de/WDCC/ui/cerasearch/"}, "publisher":{ "@type":"Organization","name":"Earth System Grid Federation", "url":"http://esgf.llnl.gov"},"includedInDataCatalog":{"@type":"DataCatalog", "name":"Earth System Grid Federation","url":"https://esgf-data.dkrz.de/search/esgf- dkrz/"},"@id":"https://doi.org/10.22033/ESGF/CMIP6.1534", "name":"CMIP6.CMIP.IPSL.IPSL-CM6A-LR", "url":"https://doi.org/10.22033/ESGF/CMIP6.1534", "license":"http://creativecommons.org/licenses/by-sa/4.0/","description":"Coupled Model Intercomparison Project Phase 6 (CMIP6) data sets.\nThese data includes all datasets published for 'CMIP6.CMIP.IPSL.IPSL-CM6A-LR' according to the DRS .","datePublished":"2018","author":[{"@type":"Person","name":"Boucher, Olivier"},{"@type":"Person","name":"Denvil, S bastien"},{"@type":"Person", "name":"Caubel, Arnaud"},{"@type":"Person","name":"Foujols, Marie Alice"}]}</script> 5 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018

  6. CMIP6 Citation Service Relations (3) Data Usage in Literature (Scholix): Get data reference into reference lists of articles (Enabling FAIR data / RDA IG ESES with author guidelines; CMIP6 User Guide) Get information about data references in papers: CrossRef + Scholix API (RDA/WDS Scholix WG; http://www.scholix.org ) Add paper references to CMIP6 Citation database Update registered DataCite Metadata and XMLs on OAI Server Integrate data usage into annual data download statistics, e.g. for IPCC DDC Integration into PCMDI s publication hub and ESGF Dashboard: As part of IS-ENES3 Service Activity it is planned to make the information about data usage in literature available for PCMDI s publication hub (available for project coordination) ESGF Dashboard statistics (available for DN Managers) 6 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018

  7. CMIP6 Citation Service Status (1) Citation Service in Numbers (2018-12-03) CMIP6: input4MIPs: 110 citation entries are available. 7615 citation entries are available: 615 on model/MIP granularity and 7000 on experiment granularity. 22 DataCite DOIs are registered. 44 citation managers are registered. (2 institution_ids without a cm) 44 institutions with 110 models registered (+ one open request) 292 CMIP6 experiments (all MIPs/tiers) 55 DataCite DOIs are registered. 16 citation managers are registered. 345 DataCite metadata XMLs have been registered (incl. updates). 7 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018

  8. CMIP6 Citation Service Status (2) Service Components: Specifications at: http://bit.ly/1XsVOoz Virtual Machine for backbone functionality in observing phase stability of service Oracle APEX GUI is operational but was improved in terms of usability and validation Provider API was added and is operational insert experiment granularity Dissemination API is released and operational (bug fixes during 2018) ESGF DN manager API to check for data citation completeness planned Landing page with dynamic content and XML/JSON export is operational, ESGF CoG implementation is done Tool for creation of input JSON for Provider API planned; Zeb s tool is an option but needs to be checked volunteers? (https://github.com/znicholls/CMIP6-json-data-citation-generator ) 8 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018

  9. CMIP6 Citation Service Status (3) Technical Functionality: Insert information from CV is a semi-automated process requiring checks Registration of DataCite metadata/DOI is automated (hourly) and operational Update of DataCite metadata and XML on OAI server is automated (daily) & operational (DKRZ s OAI server: http://dm-oai.dkrz.de:8080/oai/provider , set: esgf-datacite ) Integration in furtherInfo URL landing page is done in basic way Metadata curation needs to be improved and partly automated Scholix integration about data usage in literature is in test phase exchange of OpenAire API to DataCite Event Data API planned Full implementation of RDA WGDC recommendations would require a second PID on the used data subset (integration in replication and LTA strategies required CMIP7) 9 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018

  10. CMIP6 Citation Service Status (3) Documentation / User Support: CMIP6 User Guides Modelers: updated in 2018 but otherwise done Data Node Managers: under review and DN manager API missing Data Users: basic information on data citation Citation Service Webpage (cmip6cite.wdc-climate.de): central point of information, continuously updated Citation Manager Tutorial: update for Provider API part under way WebEx for Citation Managers: two done in 09/2018 CMIP6 User Support Infrastructure: due to staff resources the integration of the citation service user support into the CMIP6 support infrastructure is planned. 10 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018

  11. Summary / Improvements for CMIP6/AR6 CMIP6 / AR6: Data Citation: CMIP6 data are citable IPCC DDC AR6 data are citable incl. references to CMIP6 data Get credit: Authors and contributors with ORCID, CrossRef FunderID or other IDs Give credit Data References (input4MIPs), Paper References Google Dataset Search Get usage statistics Downloads Scholix services provide information on data usage in literature IS-ENES3: PCMDI s pub hub, ESGF dashboard CMIP5 / AR5: Data Citation: CMIP5 data are not citable IPCC DDC AR5 data are citable to late for many publications Get credit: Authors and contributors without ORCID or other IDs Give credit No Data References; Paper References Google Dataset Search Get usage statistics Downloads No tracking of data citations in literature 11 Stockhause & Lautenschlager: Data Citation Service ESGF 2018, 05.12.2018
