How this entity was disambiguated
This entity first appeared as the object of triple T10532237 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: RFC 6668 Context triple: [R. Barnes, authorOf, RFC 6668]
-
A.
RFC 6668
RFC 6668 is an Internet Engineering Task Force (IETF) standard that updates the Secure Shell (SSH) protocol to add support for modern elliptic curve cryptography methods.
-
B.
RFC 6066
RFC 6066 is an Internet Engineering Task Force (IETF) standard that specifies Transport Layer Security (TLS) extensions, including the widely used Server Name Indication (SNI) extension.
-
C.
RFC 6698
RFC 6698 is the Internet standard that specifies the DNS-Based Authentication of Named Entities (DANE) protocol, which uses DNSSEC to associate TLS certificates with domain names.
-
D.
RFC 6856
RFC 6856 is an Internet standards document that updates and extends the Post Office Protocol version 3 (POP3), superseding earlier specifications such as RFC 1939.
-
E.
RFC 6864
RFC 6864 is an Internet Engineering Task Force (IETF) standards-track document that revises and clarifies the semantics and usage of the IPv4 Identification field in IP packet headers.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: RFC 6668 Description of subject: RFC 6668 is an Internet Engineering Task Force (IETF) standard that specifies the use of SHA-2 data integrity verification algorithms within the Secure Shell (SSH) protocol.
