| Name | Data Type | Default Value | Qualifiers |
| Name | Data Type | Value |
| EntityID | string | |
| Description | string | An ID representing the resource identified by this entity. For example, the WWN or the URI of an element. The property Type is to be used to interpret the ID. |
| InstanceID | string | |
| Description | string | Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm:
<OrgID>:<LocalID>
Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>.
<LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If the above "preferred" algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance.
For DMTF-defined instances, the "preferred" algorithm must be used with the <OrgID> set to CIM. |
| Key | boolean | true |
| Override | string | InstanceID |
| OtherTypeDescription | string | |
| Description | string | Populated when "Type" has the value of "Other". |
| Persistent | boolean | true |
| Description | string | If false, the instance of this object, not the element represented by this entity, may be deleted at the completion of a copy operation. |
| Write | boolean | true |
| Type | uint16 | |
| Description | string | Indicates how to interpret the information appearing in EntityID.
Encoded in EntityID: indicates the ID has an implementation specific method of including the entity type in the ID. For example: "vol+foobar" says the entity represents a volume called foobar. |
