How to bulk update metadata?

Hi there,

We would like to update bulk update a metadata field for one of our journals and are unsure if this is possible.

We’ve found that the ‘date published’ metadata field for each article is empty and when we submitted these articles to Crossref the xml contained 1970 as the date.

Can I use the xml import/export tool to do this?

I’m here looking for the same feature and as far as I can tell, it can’t be done using the Native XML Plugin. When I upload an exported issue XML with small modifications to the article records, the article records are added as new records even when the article ID remains the same. I’m about to experiment using the OJS 3.1 API to update records but I fear it won’t work because I don’t see a PUT method in the API documentation.
