In online communities where the objective is to create and share step-guided learning content, there is a need to emphasize the links between knowledge entities. This is due to the fact that they intend to provide their users with learning pathways to follow from one section/chapter/module/page to the next one to achieve a specific learning objective.

Even before starting the learning journey, they also often emphasize the prerequisites that one should have covered before starting to study the learning content that they offer. Sometimes, they also suggest follow-up courses that the learners can go through after completing the learning material.
