Hi Clifford:

Frankly, you will not be able to get that assurance in any global way. The IPR issues with crawling and extracting Web information are non-trivial and reason for several lawsuits and bilateral agreements. Schema.org cannot make any such statements, for the sponsors just provide the vocabulary, not the data.

See here:

    https://benbernardblog.com/web-scraping-and-crawling-are-perfectly-legal-right/

for a few links.

That is the reason why e.g. republishing data gained from Web crawls is problematic in research projects.

One neat idea would be, however, for the sponsors of schema.org to change the license of schema.org to a "copyleft" one, i.e. by using schema.org on your Web site, you attache a liberal license to your content. Not the most friendly move, but maybe one that will save us a lot of trouble in the long run.

Best

Martin

But OSM takes a conservative approach to licensing. I was looking for a statement that says something like "...grants you the right to use and redistribute the data..." when the schema is lacking a licence property.

There is a property "license" which is shown as being used by 1000 to 10,000 domains. Is there documentation that websites using the schema agree to a license?
