ORCID JSON-LD incorrectly asserts that article DOIs are the "sameAs" journal ISSNs!
The JSON-LD returned for an ORCID can contain some clearly incorrect assertions. For example, for https://orcid.org/0000-0002-8497-8908 we have entries that include ISSNs, e.g.
The JSON-LD for this record looks like this:
{
"@type": "CreativeWork",
"@id": "https://doi.org/10.1007/s12686-010-9350-y",
"name": "Thirteen polymorphic microsatellite markers for the European green toad Bufo viridis viridis, a declining amphibian species",
"identifier": [
{
"@type": "PropertyValue",
"propertyID": "issn",
"value": "1877-7252"
},
{
"@type": "PropertyValue",
"propertyID": "doi",
"value": "10.1007/s12686-010-9350-y"
},
{
"@type": "PropertyValue",
"propertyID": "source-work-id",
"value": "cv-prod-id-1913589"
},
{
"@type": "PropertyValue",
"propertyID": "issn",
"value": "1877-7260"
}
],
"sameAs": [
"https://portal.issn.org/resource/ISSN/1877-7252",
"https://portal.issn.org/resource/ISSN/1877-7260"
]
}
The sameAs assertions are clearly false. The article with DOI https://doi.org/10.1007/s12686-010-9350-y is not the same thing as the journal with ISSNs 1877-7252 and 1877-7260.
Without looking at the source code I assume there is a blanket rule that any resolvable identifier in addition to a DOI is automatically an identifier for the article. This is clearly incorrect.
I note that records where the web page displays the article as having a Part of relationship with on for more ISSNs don't display ISSNs in the JSON-LD, e.g. the record for https://doi.org/10.11646/zootaxa.4759.4.12 for the same ORCID:
