Everything dealing with data is an Indicator in SERAM. In order to identify the different indicators, they are each assigned a code, a name and a description.
The metadata of the indicator is not specific to a reporting period / year, but the configuration of the indicator is. This allows you to simply make comparisons over multiple reporting periods even if the indicator configuration has changed over time.
Also, the name and description can be translated into multiple languages, which enables your users of different languages to use the system in a self-explainaory way.
