The [HL7 OID registry](http://www.hl7.org/oid/index.cfm) is structured as follows: `1`: HL7 registered internal objects (other than published documents and organizational bodies); `2`: HL7 organizational bodies and groups; `3`: External groups that have been issued an HL7 OID root for their own use; `4`: Registered externally maintained identifier systems and namespaces; `5`: HL7 Internal Code Systems; `6`: Registered external coding systems (with an HL7 issued OID); `7`: HL7 published documents (standards, tutorial slides, implementation guides, databases, published Reference Information Model (RIM) graphic billboards, etc); `8`: HL7 OID registered documentation products and artifacts; `9`: HL7 Registered conformance profiles; `10`: HL7 Registered Templates; `11`: HL7 defined and registered Value Sets; `12`: HL7 Version 2.x tables as code systems; `13`: Externally authored and curated Value Sets, HL7 registered; `14`: Internal use; `15`: Small code sets externally defined (similar to v2.x tables); `19`: HL7 Examples Root used for published examples; meaningless identifier, not to be used for any actual entities. See also the not-authoritative [overview of OIDs used in European HL7 artefacts](http://www.ringholm.de/docs/00900_en.htm) maintained by [Rene Spronk](mailto:Rene.Spronk@ANTISPAM.ringholm.com). The process of registering an OID with HL7 is the addition to a central registry of an OID and its descriptive data. The OID doesn't have to be within the HL7 root OID or any specific other root or branch OID. Once a scheme has been registered, no other OIDs that identify the same scheme can be registered. ### Registrant Name: W. Ted Klein Address: On behalf of Health Level Seven, Inc.
