Arkisto uses RO-Crate, which 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 schema.org 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 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
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
RO-Crate is the result of international collaboration, and has an actively-maintained specification.
