Hello,
The ISSN International Centre is currently working on the addition of schema.org mark-up to the ISSN bibliographic records published on http://road.issn.org (beta version).
I wonder if we should use the property http://schema.org/contentRating or https://schema.org/reviewRating for journal indicators (e.g. SNIP, SJR , Impact Factor) ?
Additionnally, what property could we use for the data related to the indexing/abstracting of a resource ? (e.g.: the International Journal of Philosophy is indexed/abstracted by Scopus, see also the MARC 21 field n°510: http://www.loc.gov/marc/bibliographic/bd510.html):
https://schema.org/review or an inverse property (which does not exist yet -) of https://schema.org/citation ?
Could someone advice ?
In other respects, I would recommend that you create the property ISSN-L for periodicals (ISSN-L = linking ISSN, it is used for collocate the various medium versions of the same resource, see http://www.issn.org/understanding-the-issn/assignment-rules/the-issn-l-for-publications-on-multiple-media/).
Thank you very much in advance for your advices.
