Invalid object type for field "distribution"

[pdurbin]

Not long after we deployed our Croissant implementation to Harvard Dataverse, we got this email about Invalid object type for field "distribution" from the Google Search Console Team:

I followed the link...

... and tried the first example URL at https://validator.schema.org/#url=https%3A%2F%2Fdataverse.harvard.edu%2Fdataset.xhtml%3FpersistentId%3Ddoi%3A10.7910%2FDVN%2FRU1X7W

It does show errors around the "distribution" field. Specifically: http://mlcommons.org/croissant/FileObject is not a known valid target type for the distribution property. It looks like this:

Did I do something wrong with my Croissant implementation?

Does the Google Search Console not (yet) know about Croissant? 🥐

Thanks!

Hi Phil,

Indeed the Search console doesn't know about Croissant yet. It only validates mark-up based on the schema.org vocabulary, which expects distribution to be of type sc:DataDownload. I will get in touch with them to figure out how to best address this issue.

Best,
Omar
