Scan and fix incorrect metadata
Is there a way (built in or through a plugin) to automatically download missing metadata for a record? Or a way to scan a record and check the metadata against a database like PubMed or Google Scholar to check that the metadata is correct?
I built a system for my online database service (SafetyLit) to automatically query the PubMed system API and refersh volume-issue-pagination metadata and it works well. The problem is that having access of that kind requires a license. Although the license has no cost and can be had quickly, it must be renewed each year and there is a restriction based on IP range. Parts of the NCBI databases have become license free effective October 2016. I hope that access to refresh metadata will also soon no longer require a license.
For items not included in PubMed, we are working on a similar system that uses CrossRef, LoC, and other national libraries. Unless things change, the CrossRef and LoC will not require a license for datafase access. The main block from accomplishing this is our budget restraint and a few things that have a higher priority. I expect this by the end of March 2017.
My offer to share the code stands open, but until the license issues work themselves out, they aren't very useful to others.
