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.

Topic or Fork

The cross reference dialog shows the targets both as part of the publication (fork) and outside the publication tree (topic or subpublication). When you insert a cross-reference in topics, you can link to either a topic or a fork. It is important that you understand the difference, as it will produce different results.

• Topic

  If the topic you want to link to only appears once in the publication, cross-reference the topic directly. Select the topic with the black icon.

• Fork

  If the target topic appears multiple times in the same publication, link to the fork in the publication. To do this, find the publication in the New cross reference dialog, expand it to reveal its forks, and then select the fork for the topic. Forks have a gray icon.

  Fork cross-references link to the topic's specific position in the publication structure. Be aware that the link only works if the topic containing the cross-reference is in the same publication as the fork.

Gray document icons inside publication structures are forks. Black document icons are topics.
