Hello Francois,

It is known issue (please look http://www.w3.org/2011/webschema/track/issues/5). For now it is decided that "it is always allowed to have multiple values."

Thanks!

Subject: [Feedback on schema.org] singular/plural for property names and multiple values

[Note I send separate emails to keep separate discussions separate, my intention is not to flood the list ;)]

The "Note on naming conventions" in the extension mechanism says:
[[ Properties that can take multiple values (such as parents) are plural and those that can take only a single value (such as
dateOfBirth) are singular ]]
http://schema.org/docs/extension.html


That triggers a question for e.g. Author, Contributor, Editor for a CreativeWork. There may be more than a single value for these property, yet they are in the singular form. Am I right to assume that, even if the property is singular, it is good practice to specify multiple values where it makes sense? (I get it does not make sense for dateOfBirth for instance).

If so, could the documentation be perhaps clearer as to which properties are expected to take multiple values and which are not?

Taking the latest technical report published by W3C as an example:
 http://www.w3.org/TR/2011/REC-ws-transfer-20111213/


If that spec was to be marked up, there would be four "Editor".

Thanks,
Francois.
