Doing verification of triples, I noticed that many entities have not only one correct link in the “Official website” field, for example in the format https://<site_url>, but also slightly changed, but also working, for example http://<site_url> or http://www.<sitr_url>.
It seems to me that there should be some restrictions on such triples.
For example, in the field “official website” can not be two links that differ only in protocol https or http.
