• retrieve from the configuration management database one or more configuration records containing the identified host value, and
• select from the one or more retrieved configuration records a configuration record depending on the number of matches between the unidentified attribute values and the attribute values of the retrieved configuration records, wherein each of the unidentified attribute values includes an attribute value whose semantics are unknown.
