HttpLink
From Wiki
An HttpLink is a link to an internal or external web page.
HttpLinks are associated to SOPs or Galleries.
An HttpLink is "uploaded" by a EVI-Genoret member to describe a SOP or Gallery.
The upload procedure is done in the same manner as for a Datafile except that there is no transfer of data but only of the address of the link.
An HttpLink has also a Title, Description and Owner
There is no Visibility Group associated to an HttpLink : all_people can see the link (and click on it)
An HttpLink can be referenced from several distinct SOPs and Galleries.
