Variable, i.e., a conventional that is employed for something to which values can be assigned (this may include different notations for the same variable including, e.g., computational representations); this is to be understood very generally, e.g., a variable may be an array or set of elements or have another kind of internal structure

A role is the function of an entity or agent with respect to an activity, in the context of a usage, generation, invalidation, association, start, and end.
Role
The function of an entity or agent with respect to another entity or resource.

A keyword or tag describing the resource.
keyword
Person or Organization related to a StandardNameTable.
Agent
Attribution is the ascribing of an entity to an agent. When an entity e is attributed to agent ag, entity e was generated by some unspecified activity that in turn was associated to agent ag. Thus, this relation is useful when the activity is not known, or irrelevant.

Person
The prov:agent property references an prov:Agent which influenced a resource. This property applies to an prov:AgentInfluence, which is given by a sub-property of prov:qualifiedInfluence from the influenced prov:Entity, prov:Activity or prov:Agent.

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](http://cfconventions.org/), 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 core idea is to provide the class StandardName and StandardNameTable with a minimal set of properties. The rules of standard name construction is defined in a document associated with the standard name table. 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](https://nfdi4ing.pages.rwth-aachen.de/metadata4ing/metadata4ing/) for a concise description of a numerical variable.
sSNO: A simple Standard Name Ontology
A generic Standard Name. Intended to be used to refer to any Standard Name, e.g. by relating the position of a qualification to it, i.e. to be placed before or after a Standard Name.
Ein generischer Standardname um Qualifications in Relation zu setzen.
Any Standard Name
Representing any physical unit.
any unit
Character
Represents a predefined group of valid domain-specific concepts such as devices.
Domain Concept Set
A qualification derives an existing standard name by a rule. This may alter the units.
See here https://cfconventions.org/Data/cf-standard-names/docs/guidelines.html
Qualification
A standard name associated with scalar data.
Scalar Standard Name
A standard name is defined by a canonical unit and a description. It generally is defined by a standard name table.
Standard Name
A concept which defines the construction of a standard name, e.g. by adding specific phrases following well-defined rules. It extends or changes a base standard name and hence may or may not change the unit of it.
Standard Name Modification
v2.0.0: Added seeAlso, isDefinedBy and source pointing to https://cfconventions.org/.
v2.0.0: Modelled as skos:ConceptScheme to better align with SKOS best practices.
v2.0.0: Removed ssno:hasVersion and use schema:version instead.
A standard name table holds a list of all available standard names used in a certain context (project, domain, ...) and gives further information about version and contact.
This class models the concept scheme that captures a subset of the CF conventions' standard names.
Standard Name Table
A transformation is a phrase which may be added to the standard name without changing its unit.
Transformation
A vector component qualification holding values like "x", "y" and "z" can modify vector standard names like "velocity" but not scalar standard names like "pressure".
Special Qualification accounting for Vector Standard Names. Only one such Qualification must exist at max in a StandardNameTable
Vector Qualification
A standard name associated with vector data.
Vector Standard Name
Refers to another qualification to indicate the order. The qualification it points to is ordered before this one. It can also point to a standard name, which means that this qualification is used right after it.
after
Indicates that a standard name individual is an alias of another.
alias
A string defining how the new unit is generated.
"[X] s-1" where [X] is the unit of the standard name X.
alters unit
Used to provide metadata about the data the property is provided with. E.g. uncertainties can be expressed/linked like this. As stated in the cf-conventions, the "nature of the relationship between variables associated via ancillary_variables must be determined by other attributes" https://cfconventions.org/Data/cf-conventions/cf-conventions-1.7/build/ch03s04.html)
ancillary variables
Associates a character to a thing, which is intended to be a AnyStandardName or a Qualification.
associated with
Refers to another qualification to indicate the order. The qualification it points to is ordered after this one. It can also point to a standard name, which means that this qualification is used right before it.
before
A character i.e. a single letter or symbol
character
Relates a standard name table to a dataset, which is published and available for access or download in one or more representations.
dataset
Description of a Standard Name, a qualification or a transformation.
description
Links a transformation to a character used in the transformation string to represent a standard name or qualification
has character
Links a domain concept to a standard name table. An example for a domain concept defined by a standard name table can be devices used in an experiment and which a transformation relates to.
has domain concept set
Points to a Qualification or Transformation defined by a Standard Name Table
has modifier
A data property that stores prepositional qualifiers like "at," "in," "due to," and "assuming." to be used with Qualifications.
The CF Convention uses the qualification 'in process' where 'in' is the preposition and 'process' the qualification.
has preposition
Points to a ssno:StandardName associated with the Concept. The Concept should is expected to be describing a numerical quantity because a ssno:StandardName defines and describe a numerical quantity by providing a description and expected canonical unit.
has standard name
A relationship defining a set of values used by the qualification.
has valid values
Points to a Concept, that describes a numerical variable, which uses the standard name.
is standard name of
A human-readable label of a variable which is should be used in addition with a standard_name. As intended in the cf-conventions (https://cfconventions.org/Data/cf-conventions/cf-conventions-1.7/build/ch03s02.html), it may be used for labeling plots.
long name
Relates two qualifications or one qualification and a standard name to each other.
positioned
Name for a standard name, e.g. "x_velocity". The construction of a standard name string is defined by the standard name table. E.g. no spaces are allowed and specific pre- and suffixes are allowed.
x_velocity
standard name
The character which is used in a standard name transformation string to indicate the position a standard name used in the modification rule.
in the transformation string "integral_of_Y_wrt_X" the standard name representation characters are be "X" and "Y"
standard name character
v2.0.0: Declared as subproperty of skos:inScheme.

v1.5.0: ssno:usesStandardNameTable is subtype of dcterms:relation
