Chairs	Conclusion	5
Abstract:We present and discuss the metadata management in National Astronomical Data Center of China in terms of standards and system. Practices are shared on aspects of data taxonomy, metadata granularity in relation to IVOA resource metadata standards, design of metadata management and data submission system serving the process from metadata submission to data Release. Also, we want to discuss the best practices for data quality assessment. Co-authors: HUO, Zhiying; HE, Boliang; MI, Linying; CUI, Chenzhou

Introduction from Andre Schaaff

• DCP areas of interest.
• RDA: FAIR, Data Citation, Certification.
• Work on note on DOIs restarting.
• Endorsed note because generic notes are hard to cite and a document on DOIs would be good to be citeable.
• Xiquin Wu: NED is very close to publish the Best Practices for Data Publication in the Astronomical Literature. A draft is available here http://ned.ipac.caltech.edu/docs/BPDP/NED_BPDP.pdf -- This is an update of a 2013 document.

• Question from speaker about how to manage data quality flags for data collections.
• Not entirely clear how registry can do anything other than trust.
• What happens if downstream user determines that data are not as well calibrated as thought? Who decides how to change the flag?
• Schaaf: How did certification work?

Andre Schaaff: Presentation on RDA status

• Schaaff: What is the equivalent of European Open Science Cloud (EOSC) in other places? [No response.]
• Xiuqin Wu: Next ADASS will have a theme “FAIR standards for astronomical data”. Maybe someone wants to give a presentation there.

Questions

• Bonnarel: Question on FAIR data principles. Some issues meeting the entire set of principles in astronomy. Reproducibility is problematic (maybe the calibration has improved).
• Raugh: Reproducibility is not in FAIR principles. Clarifaction is requested.
• Bonnarel found the presentation on this topic from previous meeting. Confirms reproducibility requirement not in FAIR. There was an issue with global persistent identifiers.
• Raugh: Findability is important. Knowing who to email is not findable.

Schaaff: Future topics.

What do people want to focus on in this group after the release of the endorsed note for DOIs?

• Certification? FAIR? Data integrity?
• James Dempsey: Has written document on data security and CoreTrustSeal. Volunteers someone from his organization to give a talk on the process in a future meeting.
• Severin Gaudet: CADC also looking at CoreTrustSeal. Initiating work on this later in year.

How to participate to the DCP IG ?

• Anyone interested in data curation and preservation is welcome to participate and to register to the mailing-list (archives) to receive the news.
• The presentations and discussions are held during the semestrial IVOA meetings, do not hesitate to participate.
