Introduction

For Researchdata.se to be able to harvest dataset metadata from a data source such as a repository, a machine actionable way to access the metadata is needed.

To avoid a Researchdata.se-specific method, we recommend using established metadata standards like DataCite XML via OAI-PMH and/or Schema.org JSON-LD one the landing page via sitemap.xml.
