In recognition that metadata is essential for discoverability and reuse of scholarly works, Crossref will launch the "Metadata 2020" campaign to encourage richer metadata deposits from publishers. The campaign aims to educate publishers on metadata's importance and recognize leaders in the field. Preliminary goals are to raise awareness, encourage public commitments to comprehensive metadata, and equip stakeholders with tools. Intended outcomes include greater discoverability through interconnected metadata and consistency across the scholarly community. Crossref's role is to drive awareness and provide participation reports and scorecards to publishers. The campaign timeline runs from 2016 through 2020.
