Bibliographic Save To Zotero

Current PB book webpages (i.e., a chapter page) do not provide bibliographic information to Zotero. Does this mean that a WP COinS plugin could be used, or is there another way to have bibliographic information available on all pages for Zotero?

Can you give us some more information? E.g. a link to Zotero specifications, or the plugin you are talking about? I expect there’s some metadata we would need to be including for Zotero, but I would guess the plugin you mention won’t work out of the box.

According to Zotero ( it can import different formats, with support from many Zotero fields (

However, Zotero has its own RDF with schema/ontology documentation that I have not found on the Zotero site (perhaps buried in It appears that COinS is popular as per Zotero document (

WP plugins recommended by Zotero are mostly COinS:
However, not sure if any of these plugins work in PB.
The relationship between Open URL and COinS looks promising.

Some net discussions point to Zotero developing toward the Bibliographic Ontology specification ( from (1).

An example Zotero enhancement from the Bibliographic Ontology:

An example RDF that may not be accurate for Zotero, but it is all I could find at this time:

According to Mastering Zotero (, embedded metadata that works with Google/Highwire ( will work with Save in Zotero. Mastering Zotero asserts that Google/Highwire spec produces a more complete result in Zotero than COinS (which I concur).

Zotpress ( looks promising and would be useful for Zotero users in PB.

We are working with a plugin about metadata and we can say we did finish the prototype.

Now we whant to extend the plugin for google schoolar. We did use schema for google and now we do not know wich type of language to use for google schoolar (we are thinking to use DC but google do not recomend because is a too short vocabulary). As Zotero can work with google schoolar (but is a litle more complicate to uderstan because is longer ) maybe we could integrate

If you tell me wich properties from Zotero we need and the relationship whit the fields of Book info page of PB. We will do for you

The fields of Book info page have a code in the next link

Where the metadata should be?. Just in the book cover, in any single page of the book?

and also, are there properties for the full multisite installation?

Metadata for a book needs to be in all formats, including the HTML. Each webpage of a book can be considered bibliographic (citation capable) content.

Can zotero to read ?

That is the minimum vocabulary that you need?

Is a general use area for development of vocabulary? Whereas is a very specific application?

Perhaps this URL will help?

The main issue for Zotero endusers is that a COinS embedded metadata on a webpage produces less complete data (in Save to Zotero) than other metadata formats (i.e., Google, or

If I had to choose a WP plugin for getting bibliographic data from Zotero, then Zoteropress could work (but it is not as well integrated into PB as PBTextbook plugin).

From an ontology I prefer
However, I recognize that Google Scholar needs to be able to read the HTML metadata.

I use to be a lilte lost in that topic. Shema between RDF … to many ways to do the same. Maybe we just need to choose one and to use it. As we have the base, to extend into another vocabulary should not be long.

that is RDF, the one I know I read the most. We could use it.

Could you tell me wich properties do you need?

That is the issue for extending our plugin to zotero too

I am using Protege ( to examine the properties from

The entities are extremely complex. Therefore I have gone to the source of Zotero as a guide, rather than an external source. Note that Zotero xmlns points /net/biblio#

Sorry for my missundestanging of the topic. But that file is not with different vocabularies?


rdf, z, dcterms, dc, bib, vcard, foaf, prism

Where did you find that file? did you export that data from one file you find online?

maybe the creators of the site where you find that file did use several vocabularies and zotero to integrate in one place. We need to focus in one vocabulary and in the future to extend to more if is necesary.

If you give me something more simple. Like one vocabulary and from that vocabulary you choose the fields we need (and for a future update the rest of the fields). We can handle in a few days.

As long as the fields you need are also for google schoolar, we have no problem.

PB Book Info fields do not include everything that Zotero Book entity fields have.

The main items missing from PB are the item type - book and URL permalink. Edition and volume info do not exist in PB Book Info. If Zotero recognized that the page was from a book type and the permalink, would be a good start. The edition is more complicated because there is no field yet in PB Book Info (although I wish there was).

We did extend in our plugin some or all those fields. And some more. We will use teh minimum in the next release and in the future we can extend it.


The one is not possible for now is the number of pages. As it depen of the configuration of the export (a4, a5, typo…) and the updates with the content. To have a cell for such data will be wrong many times. We believe is better not to have it.

What do you think?
