Re: How to store external article identifier?

Hi

Another solution which gives a distinction between the identifiers is to use the identifed property for the identifier that you assign and the sameAs property for all the external identifiers.

Hi Abir,

All properties in Schema.org are repeatable so the simple answer to your question is yes.

If you are storing multiple identifier values, it would make sense to capture which identifier is which,   If you have not done this before, checkout the examples that use a PropertyValue type to capture the identifier (value) and its type (propertyId) - like this:


  1.
  2.  "identifier": [
     {
      "@type": "PropertyValue",
       "propertyID": "Internal Id",
       "value":  "889647468"
       },
     {
        "@type": "PropertyValue",
        "propertyID": "External id",
        "value":  "AB23C"
     }
  ],
  3.

Hi,

I’m wondering if someone can help me with schema question regarding articles. How can we store multiple identifiers for an article? I work in a media organisation where we have articles coming from various sources, and once they get ingested they are assigned an internal identifier, but we want to be able to save their external ids as well. Can the identifier field within a Thing be a list of multiple values?

Regards
Abir
