Custom Code Systems

Besides the existing Terminology Standards, Snowray supports the creation and maintenance of Custom Code Systems that consist of a set of terms.

Schema

The Schema provides a structure to Custom Code Systems through different property types. The Code System Schema has a dedicated page where the property types can be specified. Defining properties in the Schema is not mandatory, but it definitely helps to construct a more layered Code System structure. In addition to specifying property types, users can also set a cardinality to the given property in order to establish the potential number of values.

Property Types

Property Type	Description
Boolean	True or false type properties
Integer	Properties with integer number values
Decimal	Properties with decimal number values
String	Text type properties
Date	Date type properties
URI	Uniform Resource Identifier

Cardinality

Cardinality	Description
0..0 (Not allowed)	It is not allowed to specify a value for the property
0..1 (Optional)	It is optional to specify a value for the property
0..* (Optional multiple)	It is optional to specify any number of values for the property
1..1 (Mandatory)	It is mandatory to specify a value for the property
1..* (Mandatory multiple)	It is mandatory to specify at least one value for the property

Concept

Concepts are the foundation of all Code Systems. In case of Custom Code Systems, these are usually a list of terms with their associated IDs.

If no ID is available for the terms, the system will automatically allocate one during concept creation.
