---+++ DCP Session minutes (thanks to Tim)

---++ Françoise, Trustworthy Data Repositories

   * Certification of data centers.
   * CDS got certified.
   * Useful because of the feedback from experts.
   * CoreTrustSeal preferred (ISO too expensive)
   * Strongly feel that certification is really important.

---++ André, Tim: DOI Note status

   * ADASS BoF had follow up session on DOIs.
   * Had meetings with AAS, Planetary Data and Chandra on DOIs.
   * Sent round survey asking about DOI usage.
   * Aim to release draft at Groningen meeting.
   * DOI best practices in astronomy.

Q: DOIs are primitive, aren’t we really talking about data publication best practices?

A: Survey should determine what we are covering.

---++ Raffaele: Chandra

   * Chandra migrating to persistent identifiers.
   * All papers using Chandra data should be tied to the original datasets.
   * Metrics then used to demonstrate that the archive is being used.
   * Were always required to use persistent identifiers but now switching to Datacite DOIs.
   * Want to know how much data is used for different types of publications.
   * Continually have to follow up on authors to make sure they include identifiers.
   * Can track evolution of archive usage.
   * Can also try to track when multiple datasets from different missions are combined.
   * Collection pages link paper to multiple datasets.
   * Detailed metadata plan.
   * Using DataCite metadata schema 4.1 but still needs work for astronomy.
   * Need to mint 40,000 DOIs to backfill archive.
   * Why does obscore mandata IVO identifiers and doesn’t allow use of DOI.

---++ Séverin: CADC Self-serve DOIs

   * Wanting to publish data that they have generated for their paper.
   * Cross-linking data to a paper.
   * Initially minting DOIs manually (on request) since 2013.
   * Self-serve since March 2019.
   * Publishing of VOSpace areas.
   * Files are locked once minted.
   * System set up to allow paper reviewers to see the data before minting.
   * Built on top of VO services.

Q: Are there constraints on what can be stored for minting?

A: No. Whatever author wants to put in there to be associated with the paper.

Q: How do you track raw data holdings usages?

A: CADC aren’t required to do so. Telescopes themselves care more about data usage.

Q: Where is the code?

A: Should be open source. Will make sure it’s available.

---++ Yihan : PaperData Updates

   * China-VO systems for uploading data use for journal publications to get DOIs.
   * Issuing IVOID and DOI.
   * Requires that the paper has been accepted before a DOI is issued and the metadata is complete and true.
   * Once DOI issued everything is locked.
   * Versioned DOIs are supported.
   * Compliant with AAS Journals rules.

Q: Can a DOI be reserved before acceptance of paper?

A: Not in plan at the moment.

---++ Deborah : ESA Science Archives DOI plans

   * ESA can issue DOIs using 10.5270
   * Already issue DOIs for missions and space craft for Earth observation.
   * Really want to make it easy to link data to papers.
   * ESA DOIs refer to current best calibrated version of data. No new DOI if calibration improves.
   * DOIs deliberately opaque so that people can’t guess what they mean
   * Not even sequential.
   * Formal Data releases do get DOIs.
   * Each proposal collection gets a DOI — not individual observations.
   * Proposing to mint DOIs from selecting observations from archive (as MAST do already).
   * DOIs for high level science products uploaded back to ESA.

Q: I don’t understand the single DOI even if recalibrated. This seems to go against the definition of DOI.

A: We don’t have the older calibrations of Herschel for example.

Q: Why not deprecate the original DOI pointing to a new DOI?  There is no way to reproduce a paper if the calibrated data have changed.

---++ David: RDA as relevant to DCP

   * RDA is a Multi-disciplinary organization on data management infrastructure.
   * Helpful to monitor where RDA is going.
   * Usually very high level abstractions of topics.
   * RDA is a place where you could look for relevant outputs that represent useful thinking on your subject.
   * Data citation of evolving data.
   * Prefer to archive the query rather than the data itself. The query must be able to reflect the date that the query is relevant for.
   * This is not always possible in astronomy.

Q: Zwolf has implemented  a version of the evolving data citation system.

Q: In planetary science you only get DOI to full dataset and can’t specify a subset for your paper.

---++ Carlo Maria: RDA Federation Identity Management & usage in VAMDC

   * Aim is to remove obstacles to research by dealing with federated identity.
   * Try to track an individual even if they move institutions.
   * VAMDC integrated with Scholix and Zenodo.

Q: Please respond to the DOI survey.
