This ontology is being developed by CSIRO (originally under the eReefs project) for describing datasets, such as observational datasets. It imports the observable properties ontology which allows description of feature, substance or taxon, and quantity kinds. v 0.7.2 19/12/2017 Additional alignment to OWL-Time added by SJDC - 2016-06-16 A geospatial bounding box. Bounding box A description of an observation. In the context of observational data, we have defined observations may relate to a feature, some substance or taxon and/or a quantity kind. Observation Dataset in this context is defined as observational data relating to some observations. We have defined this also as optionally having spatial and/or temporal properties.
