 A learning path is a pathway that guides learners through a set of modules (courses/materials) to be undertaken progressively (from lower- to higher-order thinking skills) to acquire the desired knowledge and skills on a subject by the end of the pathway.

     In the context of TeSS, a training material is a link to a single online training material sourced by a content provider (such as a text on a Web page, presentation, video) along with description and other meta information (e.g. ontological categorization, keywords).
 
     Materials can be added manually or automatically harvested from a provider's website.

+Workflow
+    Training workflows in TeSS are visual, step-by-step protocols that allow users to navigate materials in TeSS in topic- or task-related ways. 
+    For example, they may encapsulate typical stages of particular kinds of data analysis (protein sequence analysis, structure analysis, etc.), where each stage/node in the workflow represents a given analysis step and links to the corresponding training resources.
