Ontology Specification Draft
Abstract
This is an ontology draft for the usage of standard names as a simple way of describing complex data.It is motivated by the cf-conventions , which introduced the concept of standard names originally. However, SSNO may (at this stage) not cover all aspects of the original, therefore it is called "simple". With this ontology, its usage shall be applicable to other research topics, too.
The ontology is still under development. Please feel free to participate in this ontology by posting problems or contributions in the Git repository.
Introduction back to ToC
The core idea is to provide the class StandardName and StandardNameTable with a minimal set of properties. A StandardName at its core is a simple string value, based on specific construction rules. By enriching numerical data with a StandardName, complex information can be added by only using one attribute. An example of a such a name is "x_derivative_of_y_velocity". The name itself already suggests its meaning, however, a lookup in the respective standard name table would reveals the precise meaning (the name describes the derivative of the y-velocity w.r.t. the x-coordinate).The rules of standard name construction is defined in a document associated with the StandardNameTable. The table contains all standard names defied by a project or community. Instances of StandardName and StandardNameTable can be used e.g. in combinations with other ontologies like metadata4ing for a concise description of a numerical variable.
The below class diagram gives a quick overview of the central classes of the ontology. The ontology is still under development.
Standard names are intended to be used as attributes in netCDF4 or HDF5 files. To indicate which standard
name table is used for the file a relation between the file and the standard name table can be established as shown below
