8.1.4.1 Definition
As with the definition attribute used in SWE Common simple and aggregate data components, the definition attribute for a DescribedObject provides the ability to link to a
definition or classification within an online ontology. Relationships of this object with various other objects can then be inferred based on the ontology. There is some potential
for overlap of functionality between the definition attribute and the identification and classification properties. Some communities may prefer to primarily use classification
and identification elements, while others prefer to use the definition attribute or both.
8.1.4.2 TypeOf
The typeOf property provides a reference to a base process from which this process inherits properties and constraints. It is a key component in support of inheritance as
described in the models in Clause 7.2.3.3. Two pieces of information required in order to reference a base process instance, the
uniqueID of the process and a resolvable URL reference to the process description. These should be provided by the xlink:title and xlink:href attributes, respectively.
Requirement
http:www.opengis.netspecsensorml2.0reqxmlcore-processtype-of-reference
Req 56. The typeOf property shall require meaningful values for the xlink:title and xlink:href attributes. The uniqueID of the referenced process, given by its
gml:identifier property, shall be the value of the xlink:title attribute, while a resolvable URL to the reference process description shall be the value of the
xlink:href attribute.
An example of the typeOf property is given below:

8.1.4.3 Abstract Configuration
The optional configuration property takes an AbstractConfiguration as its value, which provides a placeholder for configuration information in the AbstractProcess. A concrete
class supporting configuration will be provided in a higher-level conformance class in Requirements Class: Configurable Process Schema in Clause 8.6.
