ARL visiting program officer Cynthia Hudson-Vitale recently contributed a post on the Crossref blog about how SHARE uses metadata from Crossref and what future Crossref functionality would be useful for SHARE. Crossref is a not-for-profit membership organization for scholarly publishing, working to make content easy to find, cite, link, and assess. SHARE uses the Crossref API to harvest metadata that Crossref has tagged, such as journal article titles, author names, digital object identifiers, journal names, and publisher names. Then SHARE processes the metadata and aggregates it into the public SHARE data set about research and scholarly activities across their life cycle.
In the Crossref blog post, Hudson-Vitale explains more about how SHARE is enhancing the metadata and making links between the metadata records for related works. She notes:
We would love to see rights-declaration metadata elements and article references/citations included in the metadata about digital objects. The rights-declaration information is invaluable for individuals who want to know what category the object is in (public domain, copyrighted, etc.), what constraints or permission requirements exist, contact information, and more. Additionally, networks of research can be discovered and meta-scholarship facilitated by making article reference lists machine-readable and openly available.
