CHRNS FAIR data at the NCNR

CHRNS Implements FAIR-data management at the NCNR
(Findable, Accessible, Interoperable and Reusable)

Searchable Metadata

• Add sample metadata through instrument control software (NICE)
  • Keywords selected from predefined taxonomy or free-form
  • Metadata linked to current sample is embedded in datafiles
• Metadata search system pulls from datafiles
  • Stored in flexible database (no strict schema)
  • Machine-accessible search API
  • Human-friendly search pages:

ORCiD integration

• 

  Users can link their ORCiD  to the proposal and user-management system (IMS)
  • Allows login using ORCiD credentials (one less password to remember)
  • Allows linking experiment metadata with ORCiD record
• Instrument Control software (NICE) pulls participant ORCiDs for experiments from IMS
  • Incorporated in DOI metadata for experiment - data citations are linked to users
• In the future, ORCiD can provide identity management for future remote computing access

Permanent Identifiers for Experiments (DOI)

• Automatic creation of permanent Digital Object Identifier (DOI) for each NCNR beam experiment
• Published to https://data.nist.gov
• Metadata included with record:
  • Experiment ID (from IMS)
  • Title and description
  • ORCiD of all participants
  • Start and stop dates
  • Links to raw data and online data processing resources
• Directly citable in publications derived from the data

Capture of Process Metadata

• Experimental conditions
• Measurement context supplied by user or by semi-automated workflows, e.g.
  • Intent of the measurement (scattering vs. background ...)
  • Relationships between measurements (grouping)
  • Identification of calibration files
• All added to searchable metadata above

Traceable Data Processing

• Track the history of all processing steps (embedded in processed file, or as a separate download)
• Machine-readable formats
• Best effort to support "replay" or reloading of the steps directly into the processing software, for verification or alteration of protocols.
• Encourage users to include this with publications of processed data (or in supplemental materials)
