Purpose

An allows to be associated with components for any specified purpose.

Data structure

An used to apply text to selected .

Field	Data type	Purpose		Part of Primary Key
id		A 128 bit unsigned , uniquely identifying this . Different versions of a reference set member share the same but have different . This allows a reference set member to be modified or made (i.e. removed from the active set) at a specified time.	NO	YES (Full/Snapshot)
		The inclusive date or time at which this version of the identified became the current version. The current version of this at time T is the version with the most recent prior to or equal to time T .	YES	YES (Full) Optional (Snapshot)
		The state of the identified as at the specified . If = 1 (true) the is part of the current version of the set, if = 0 (false) the is not part of the current version of the set.	YES	NO
		Identifies the that contains this as at the specified . The value must be a of within the metadata .	YES	NO
		Identifies the to which this belongs. In this case, set to as subtype descendant of: ??	NO	NO
		A reference to the to be included in the .	NO	NO
		The text to attach to the identified by .	YES	NO

Metadata

The following metadata in supports this :

  900000000000454005 |Foundation metadata concept|
		900000000000455006 |Reference set|
				900000000000516008 |Annotation type|
						900000000000517004 |Associated image|

Descriptor Template

The tables below show the descriptors that define the structure of the pattern and examples of the descriptors for specific that follow this pattern.

refsetId	referencedComponentId	attributeDescription	attributeType	attributeOrder
				0
				1

The for the Annotation field can be any of the " string " in the metadata . This is described in more detail under the " descriptor" section.

refsetId	referencedComponentId	attributeDescription	attributeType	attributeOrder
				0
				1

Note that in the table above, the is a of | string | in the metadata.

Annotation Reference Set Example

As no annotation reference sets are included in the International Release, these sample rows are for illustration only.

In the above example, the two URLs have been used to annotate two with images on the web. It is not recommended that this mechanism be used to annotate with text that may require translation to other . Instead, such text should be included under an appropriate type within the .
