In the context of the URR, requirements are specifications for observations or products in terms of Earth system quantities, locations, spatial and temporal resolution, latency, accuracy an many other characteristics. Most often, a requirement will be related to one or more applications in the sense that the application depends on the specified information in order to be carried out. Naming requirements requires careful considerations. On the one hand, a very general name (such as 'precipitation') may leads to overlaps with requirements for the same quantity but with different characteristics. On the other hand, a very specific name (e.g., 'precipitation for malaria early warning') may lead to duplications for the same quantity and nearly identical characteristics for other applications (e.g., 'precipitation for meningitis early warning').

The edit functions are described in detail in the Edit tutorials included in the General section for the Publish menue, specifically for the functions New, Edit/View all, Copy, Save, and Cancel.

Although Save will carry out a check for uniqueness, it is recommended to check the URR for similar or identical requirement names before entering an anticipated new requirements name into a blank form.
