Declaration of namespaces in CSPRD

Class Definition

The Entity class is defined by the attribute values:

 

localNamespace

Value:   icom

localName

Value:   Entity

extendsFrom

Value:   icom:Identifiable

 

Property Definitions

The Entity class inherits property definitions from super classes.

The Entity class MUST have the property definitions:

 

icom_meta:attachedMarker

Description:                                              Zero or more markers applied on an entity.

Required:                                                  False               

Inherited:                                                  False

Property Type:                                        icom_meta:Marker

Cardinality:                                                Multi

Updatability:                                            Read Only

Class Definition

The Marker class is defined by the attribute values:

 

localNamespace

Value:   icom-meta

localName

Value:   Marker

extendsFrom

Value:   icom:Artifact

 

Property Definitions

The Marker class inherits property definitions from super classes.

The Marker class MUST have the property definitions:

 

icom_meta:markedEntity

Description:                                               A marked entity.

Required:                                                   False

Inherited:                                                   False

Property Type:                                         icom:Entity

Cardinality:                                                Multi

Updatability:                                             Read Only
