refreshing pdf meta-data
I've got many pdfs, and meta-data for most was fetched by Zotero. But it was done using Google Scholar before better options were available/working, afaik. Significantly, there is no DOI in most cases. More recently, with crossref, the meta-data is better.
How can I "redo" all the old ones using crossref as the resolver, to get better meta-data including the DOI? I can see no way other than essentially throwing all the existing meta-data away and starting again.

The best way to fix this would likely be to get fresh metadata from the publishers' websites - CrossRef, too, isn't the greatest sources (e.g. you won't get any abstracts) - using a link resolver (you can customize that for your library in ZOtero's advanced tab of the preferences) may help.
