Figure 1: Generic structure of BOPDB
The BOP Database Ontology is designed based on the latest version of InfluxDB (v2.0) and covers the key concepts of InfluxDB data elements. Due to the stability of InfluxDB developments, the ontology could also be used to describe previous versions of InfluxDB. Concepts in BOPDB match with the InfluxDB concepts of v1.3 and later. Figure 1 shows the structure of the ontology. It also shows how the ontology could extend BOP by including bop:Property and bop:Database in the schema. Field keys are in practice used to describe properties of the measurement and therefore relate to a bop:Property. Tag keys are used to describe additional metadata, such as the location of the measurement or the researcher making the measurement, and could therefore be linked to a wide range of instances. Some date formats have been added as subclasses of bopdb:DateFormat. However, this list is incomplete by definition. It is likely to be extended in the near future.
