Metadata: Research Object Crate (RO-Crate)

RO-Crate is a method for describing and packaging research data from ANY discipline into distributable, reusable Digital Objects with any amount of detailed metadata from simple who/what/where discovery-oriented description to metadata at the file-level or even variable level inside files.

RO-Crate is an implementer-focussed guide to best practice and is based on widely-used standards with annotations in JSON-LD and aims to make it easy to creat good quality metadata description tools which are accessible and practical for use in a wide variety of situations; from an individual researcher working with a folder of data, to large data-intensive computational research environments.

RO-Crate is used in the UTS Research Data Portal and the Modern PARADISEC demonstrator for all data objects.


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



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


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


Provenance and workflow information can be included - to assist in data and research-process re-use


RO-Crate Digital Objects may be packaged for distribution eg via Zip, Bagit and OCFL Objects
