Embedded metadata /RDF not getting dublin core dc / dcterms tags from WHO website

[mvolz]

https://github.com/zotero/translation-server/issues/82

I'm using translation-server and I'm getting no response from the translator:

curl -d 'http://apps.who.int/iris/handle/10665/70863' -H 'Content-Type: text/plain' http://127.0.0.1:1969/web

returns []

but there are a lot of metadata tags in the site:

If you look at the log, Zotero isn't using Embedded metadata to import. It uses COinS instead. More often than not, that's the better choice, although it very much isn't here. There is ongoing work to integrate the various generic translators, but until that's finished, this will occasionally happen.

[dstillman]

This is a weird case, though — because of how the COinS translator works, it doesn't even fall back to webpage saving, which is definitely not ideal. It seems like we might be able to throw an error when newItems.length is 0 to trigger the fallback. @mrtcode, should we do that here (if possible) or just wait for the combined translator?

[mrtcode]

Yeah we could throw an error in the COinS translator. Just we have to make sure this wouldn't have any unintended consequences for other translators which are embedding it. But this isn't the only COinS translator problem. It also blocks EM translator by returning poor metadata, which is more common than no items.

And generally, translators that are targeted to many websites should be very carefully developed.

[adam3smith]

I think we can close this specific issue: There's a dedicated WHO translator that works on the above-linked page and there are separate tickets (most notably #1092 ) for comprehensive generic translator
