What is RO-Crate?

https://www.researchobject.org/ro-crate/

RO-Crate is method for describing a dataset as a digital object using a single linked-data metadata document

The dataset may contain any kind of
data resource, about anything, in any format
as a file or URL

Adapted from https://arkisto-platform.github.io/standards/ro-crate/

Each resource can have a machine readable description in JSON-LD format

A human-readable description/preview can be in an HTML file that lives alongside the metadata

Provenance and workflow information can be included
– to assist in re-use of data and research processes

RO-Crate Digital Objects may be packaged for distribution eg via Zip, Bagit and OCFL
– or simply be published on the Web

Distribute metadata with data

schema.org JSON-LD from DataVerse

95% RO-Crate

Where did that lovely metadata go..?

Where's the DOI?

How do we know it's from a Dataverse?

What is this dataset called?

Import data with metadata

Avoid re-filling metadata already captured

(e.g. from workflow system or Describo)

Move RO-Crate between repositories

Build RO-Crate early and incrementally -
not just at Dataverse deposit time

Self-publish RO-Crate (e.g. project website)
with Dataverse references & DOI

Store data with metadata
