ClassificationSystems Schema
Alias: clsf
Version: 1.0.3
A schema for classifying elements
This schema contains classes for modeling classification systems, which are organized sets of definitions used for classifying or categorizing real-world Objects.
In BIS, a ClassificationSystem consists of one or more ClassificationTables. Each ClassificationTable is an ISubModeledElement whose sub-model holds Classifications. Within the sub-model, the Classifications can be arranged in a hierarchy using the ClassificationOwnsSubClassifications parent-child relationship and grouped using ClassificationGroup and ClassificationGroupGroupsClassifications.

Entity Classes
Classification (Classification) EntityClass 
An element that represents a single entry in a classification system
Base Class: BisCore:DefinitionElement
Properties
| Name | Description | Type | Extended Type |
|---|---|---|---|
| Description | Description for this Classification | string |
Inherited properties
| Name | Description | Type | Extended Type |
|---|---|---|---|
| Model | The bis:Model that contains this bis:Element. | navigation | |
| LastMod | The last modified time of the bis:Element. This is maintained by the core framework and should not be set directly by applications. | dateTime | |
| CodeSpec | The CodeSpec property identifies the bis:CodeSpec used to generate and validate the code value for this bis:Element. The combination of CodeSpec, CodeScope, and CodeValue properties must be unique for each bis:Element instance. | navigation | |
| CodeScope | The CodeScope property identifies the bis:Element that provides the uniqueness scope for the code value. The combination of CodeSpec, CodeScope, and CodeValue properties must be unique for each bis:Element instance. | navigation | |
| CodeValue | The CodeValue property stores a human-readable real-world identifier of the Entity represented by the bis:Element. The combination of CodeSpec, CodeScope, and CodeValue properties must be unique for each bis:Element instance. | string | |
| UserLabel | An optional friendly name given by the user (as opposed to the formal name stored in the CodeValue property). | string | |
| Parent | The parent bis:Element that owns this bis:Element. | navigation | |
| FederationGuid | The GUID used to federate this bis:Element across repositories. | binary | BeGuid |
| JsonProperties | A string property that users and/or applications can use to persist ad hoc JSON values. | string | Json |
| IsPrivate | If true, this bis:DefinitionElement should not be displayed in the GUI. | boolean |
