The unique object identifier ─OID─ is a hierarchy of codes that allows to identify different types of resources like Health Systems, provider centers, information systems, territorial organizations or controlled vocabularies (among which are included catalogs, terminologies, classifications or subsets). That hierarchy of codes is international, it is maintained in a distributed way and aims to minimize the errors of identification, sharing and validation of contents.
There are international OIDs (eg 2.16.840.1.113883.6.96 of SNOMED CT) and local OIDs (eg 2.16.7220.127.116.11 of the Catalan extension of SNOMED CT), depending on the situation in which they are within the global hierarchy. In this way, each number that is part of an OID identifies a level of the hierarchy, for example, in the OID of SNOMED CT 2.16.840.1.113883.6.96 we can draw the following OIDs:
And in the case of the OID of the Catalan extension:
From the OFSTI, and in collaboration with the catalog area of the eSalut Office of the ICT General Coordination, a new version of the OIDs registry has been published. In this new version, the content has been aligned with the main international registrations of OIDs, new ones have been added that were needed by the transversal projects of the Department of Health, and others that had become obsolete have been updated.
The latest version of the list of OIDs for the SISCAT can be consulted at the following link: OIDs Registry of SISCAT 19-6-2019
