The main idea is not to share just a url, but to have a thumbnail presentation with a brief or constant description.

OpenGraph was my initial proposal, I understand there are other protocols and this would only work according to the parameters assigned to these meta tags in their titles and other attributes, which in turn requires the webserver to accept exclusive requests from Meta servers or other networks.

May be considered a risk, however, by exposing only the id and itemtype as the url does but in the title, in a consistent manner and including the glpi-logo, this would be sufficient. Even the description could contain the variable "Text in the login box" from Setup -> General -> General Setup, this would give more presentation to the hyperlinks.
