# Reference Model Abstract Class: RECORD_COMPONENT
This abstract class is the super-class of all of the concrete nodes in the EHR hierarchy: COMPOSITION, SECTION, ENTRY, CLUSTER, ELEMENT, and of two abstract class nodes: CONTENT and ITEM. ## Attributes
Name | Data type | Occurs | Description
--- | --- | --- | ---
archetype_id | ST | 0..1 | The unique identifier of the archetype node to which this RECORD_COMPONENT corresponds, either in the EHR Provider system or as a mapping produced when this EHR_EXTRACT was created. The syntax for populating this attribute value is defined in EN 13606-2:2008. Within the LRA the value assigned to this attribute SHALL have no effect on the interpretation of instances of this class and the attribute SHALL not be used as a predicate for semantic data retrieval.
meaning | CD.CV | 0..1 | The standardised clinical or administrative concept to which the name attribute has been mapped. In archetyped systems it will correspond to the archetype node name. In non-archetyped systems it might be a coded term from an appropriate terminology system.
name | ST | 1..1 | The name, expressed as a coded value or as plain text, specifies the clinical or administrative concept to which this EHR node corresponds, as labelled in the EHR system in which it was first committed.
orig_parent_ref | II | 0..1 | The identity of the RECORD_COMPONENT that is the original parent (context) for this RECORD_COMPONENT, to be present if this information has been copied from another part of the EHR of this subject of care..
policy_ids | II | 0..* | This attribute identifies one or more access control policies that specifically pertain to this RECORD_COMPONENT and which need to be communicated to the EHR Recipient to govern future access to it. The identifiers may refer to policy information included in this EHR_EXTRACT as defined in EN 13606-4:2007, or to policies held in external policy servers to which the EHR Recipient has access.
rc_id | II.Uuid | 1..1 | The globally-unique identifier by which this node in the EHR hierarchy is referenced in the EHR system to which the data were first committed. This identifier shall be retained by the EHR Recipient and re-used whenever this RECORD_COMPONENT is subsequently included in another EHR_EXTRACT. Within the LRA this identifier is a persistent UUID that uniquely identifies the specalised instance of the RECORD_COMPONENT.
sensitivity | CS | 0..1 | The sensitivity of this RECORD_COMPONENT, represented using the code set for this attribute defined in EN 13606-4:2007.
synthesised | BL | 1..1 | This attribute value shall be TRUE if this RECORD_COMPONENT has been created in order to comply with this standard , but this point in the EHR hierarchy has no corresponding node in the EHR from which it was extracted.
## Relationships
Name | Class | Occurs | Description
--- | --- | --- | ---
feeder_audit | AUDIT_INFO | 0..1 | This association represents the committal and revision information specifically for this RECORD_COMPONENT in the EHR system in which it was originally committed. This association may be omitted if this RECORD_COMPONENT shares the same committal information as its parent RECORD_COMPONENT. In the case of a COMPOSITION, this association may also be omitted if the EHR Provider system is its originating system (since the data will be identical to that represented via the committal association).
links | LINK | 0..* | Any RECORD_COMPONENT may have zero or more semantic links to other RECORD_COMPONENTs.
