openOSI Object Identifier name space


An Object Identifier (OID) is used as a world wide unique identifier of objects. Others standards like GUID, UDDI exist. OID is widely recognized, mainly in the three following fields:

  1. Digital Keys (X509 certificates)
  2. Directory definition (LDAP schemas)
  3. Medical exchange protocol (HL7

 It is a structured number, using Abstract syntax notation 1 (ASN1), it is independent of machine-specific encoding techniques. It is defined by international ISO / ITU-T standard X.208 (1988) and X.680 (1995)


openOSI uses OID to define uniquely, on a world wide basis, it's specific objects in the three operational fields indicated above:

  1. Certificate practice statements (Validity condition of a given class of X.509 certificate)
  2. Definition of openOSI LDAP schema (extension of standard schema to fulfill Identity provider needs)
  3. Contribution to Research and development in the field of biomedical GRID (UDDI repository)
