 =====Motivation for this Recommendation: =====
-Many metadata elements - such as "variable" or "method" -  consist of several **components**. A variable such as “air temperature (°C)”, for example, does not only describe the measured quantity (temperature) itself, but also contains additional information (i.e., different "components"): here the measurement context (air), and the unit (°C). Since for almost all metadata elements there is room for interpretation about which specific information about a dataset is expected to be described, it is important to establish binding standards for which information (components) belong to the given metadata element. The different components of a metadatum can either be listed in separated fields, or alternatively, be listed as subsequent text string within one field following a community agreed syntax.
+Many metadata elements, e.g., a measured quantities or methods, are complex, meaning they combine terms from different categories into a single compound concept. In other words, they consist of multiple metadata components drawn from different categories.
+For example, the variable air temperature (°C) does not only specify the measured quantity (temperature) but also includes additional components: the measurement context (air) and the unit (°C).
+Because most metadata elements leave room for interpretation regarding which information they should capture, it is crucial to establish binding standards. Such standards must clearly define which components belong to a given metadata element.
+The individual components of a metadata element can either be stored in separate fields or, alternatively, combined into a single text string within one field, following a community-agreed syntax.
