Zotero Connector Empty

zecoelho

I have a site on localhost from which I'm trying to scrap metadata into the connector. This is the situation:

Localhost Site:
- metadata is defined inside the head element
- the connector detects the metadata and shows as a yellow folder icon on the browser
- when clicked, the selection list is empty

Test Site (sciencedirect.com):
- works as expected, showing list of items to select

Please find underneath more detailed info on the tests.

I would very much appreciate your help on this!

The connector parses for the DOI first and since you're using a fake DOI, it's then not returning anything. You can right-click on the Save to Zotero icon and then select "embedded Metadata" to test the metadata format (I think only the 3rd option will currently work in Zotero).

There's been steady work, though very slow progress, to unify how Zotero handles pages with just metadata (including COinS, DOIs, and embedded metadata), but the current status is the somewhat awkward priority order of the three formats that you're seeing in your test.
