I'm sorry, not much good news here:

- Zotero doesn't import keywords from generic html metatags because they're too often useless (e.g. generic site-related keywords)
- these metatags aren't particularly good for books, so no place to put number of pages, edition, publisher place or call number, I'm afraid.

You could look at COinS instead/in addition. That works much better for books.

Zotero's COinS export is a good place to start.

So far, i managed to generate a COinS which apparently include my informations :

But when i use the Zotero button, it seems like i am bypassed by WorldCat or Library of Congress (Zotero import their informations, not the ones included in my span)

Any idea why ?

@adamsmith The COinS translator calls search translators (only for ISBNs or also in other cases?) and then combines the result or only take the result of these other translators?

My first reaction is, that we might need something like this only if essential metadata like title, year or publisher is missing.

It does...sort of. The COinS translator should only revert to searching if the COinS looks sparse. In this case, your COinS has a title, but no authors listed & Zotero would rather try to find complete data that includes those creators.

Are you able to add the authors to the COinS you emit?

only creators (of any kind) and title are needed for it to use the local data.

I think you're just hitting COinS limitations at that point, sorry. I think we generally don't import the URL on purpose because the URL field is designed for citeable URLs, i.e. links to full text sources, not catalog entries. language and library catalog are just way beyond what COinS, which is a very limited data format, can handle. If you want more complex import you'll have to set up unAPI.

oh, it's definitely case that, in internet terms, these technologies are old and unAPI is basically extinct outside of Zotero -- it's very useful lightweight technology to pass high-quality metadata to Zotero without a dedicated translator though, and Zotero's support of it isn't going anywhere.
COinS is more widely used and supported (and I'm a bit baffled why all official documentation has disappeared), but its origin is in OpenURL, i.e. it is meant to just hold enough metadata to identify a work, which is why it's quite limited.

The problem is that their likely eventual replacement -- some version of JSON-LD, most likely with schema.org -- is just slowly emerging as a standard (in the sense that it's not implemented very widely) and we haven't fully implemented support yet.

I think https://www.zotero.org/support/dev/exposing_metadata caters to website/institutional users (who may either use a tool that supports zotero out-of-the-box or with a plugin and that lists pros/cons of various role-your-own alternatives).

@noksagt : you're right, that page tries to provide support but for exemple all the links for COinS are dead. So, if you want to use that method, it's kinda complicated.

Same for unAPI, the website is done.

Information that was displayed in those lost websites could be re-written and published directly in that page to raise aweressness of bibliographic data value and assist in their implementation.

But that means that first we have to find "experts" in those technologies, able to write that content, give technical recommandations on each method, maybe give exemples, etc.

Good question about tags / keywords / index terms. Yes, that is a current technical limitation but one that we could fix. I'll discuss this with my developers and, if the cost isn't too great, include keywords with the other metadata.

[edit: Know, however, that several key publishers do not provide keywords with their metadata to us (nor to those who import the publishers' metadata into Zotero). One key publisher refuses to allow their article keywords to be included with other article metadata in SafetyLit. This is why we haven't included keywords from the beginning. ]

I don't know the answer to your developer and documentation availability question.

Abstract and short title aren't a standard part of COinS. My website doesn't export article abstracts.
