Forks
A fork is a special type of link between a publication and a topic or subpublication. Paligo uses the forks when content is added to a publication.
The fork is just a reference from the publication to its content, which is stored elsewhere. This means that when you change the order of the topics in a publication, arrange them at different levels or remove content, you are just reorganizing a list of references and the order the content appear in the published output.
In many ways, it is similar to how cross-references work. When a cross-reference is added from one topic to another, you are adding a link between the topics. Paligo knows that the link leads from the current topic to another specific topic. It is a similar concept when you add content to a publication.
