Aims of FAIR Research Objects

Describe and package data collections, datasets, software etc. with their metadata

Platform-independent object exchange between repositories and services

Support reproducibility and analysis: link data with codes and workflows

Transfer of sensitive/large distributed datasets with persistent identifiers

Aggregate citations and persistent identifiers

Propagate provenance and existing metadata

Publish and archive mixed objects and references

Reuse existing standards, but hide their complexity

RO-Crate in Dataverse

First prototype: Use the COPO data brokering platform to support the processing, validation, and ingestion of standardised sample, barcode and sequencing metadata into the biodiversity genomics data ecosystem

Next:

  • Consuming as part of larger pipeline

  • RO-Crate as submission format

Attached vs Detached RO-Crate

Attached RO-Crate are used when there is some kind of folder-structure, typically archived as a ZIP file,

or on a traditional website.

 

Absolute URLs may still be listed as parts, but typically the parts are "files" and "directories" using relative paths.

{ "@context": "https://w3id.org/ro/crate/1.2-DRAFT/context",
  "@graph": [
    {
      "@type": "CreativeWork",
      "@id": "ro-crate-metadata.json",
      "conformsTo": {"@id": "https://w3id.org/ro/crate/1.2-DRAFT"},
      "about": {"@id": "./"}
    },  
    {
      "@id": "./",
      "@type": [
        "Dataset"
      ],
      "hasPart": [
        {
          "@id": "cp7glop.ai"
        },
        {
          "@id": "lots_of_little_files/"
        }
      ]
    },
    {
      "@id": "cp7glop.ai",
      "@type": "File",
      "name": "Diagram showing trend to increase",
      "contentSize": "383766",
      "description": "Illustrator file for Glop Pot",
      "encodingFormat": "application/pdf"
    },
    {
      "@id": "lots_of_little_files/",
      "@type": "Dataset",
      "name": "Too many files",
      "description": "This directory contains many small files, that we're not going to describe in detail."
    }
  ]
}

Detached RO-Crate has a standalone JSON-LD metadata file, e.g. returned by an API.

All the resources have absolute URIs
 

This style may also be suitable for a repository exposing the metadata from an RO-Crate ZIP file without exposing its individual files.

    },  
    {
      "@id": "https://example.com/item/15?crate",
      "@type": [
        "Dataset"
      ],
      "hasPart": [
        {
          "@id": "https://example.com/data/12312/cp7glop.ai"
        }
      ]
    },
    {
      "@id": "http://example.com/data/12312/cp7glop.ai",
      "@type": "File",
      "name": "Diagram showing trend to increase",
      "contentSize": "383766",
      "description": "Illustrator file for Glop Pot",
      "encodingFormat": "application/pdf"
    }
  ]
}

Thank you!

Considerations for WP1:

  • Upload computational workflows, notebooks etc. to WorkflowHub.eu!
  • Datahub to accept WorkflowHub crates
  • RO-Crate as a submission format?
  • RO-Crate as a publication/archive format?
  • RO-Crate as exchange/internal format?
  • Computational vs. data-centric vs. real world
  • Use existing specific formats (WP3) and/or lift to general metadata in crate
  • Making RO-Crate profile for DataHub
