How this entity was disambiguated

This entity first appeared as the object of triple T1869682 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Protocol Buffers
Context triple: [JSON, alternativeTo, Protocol Buffers]

A. gRPC
gRPC is a high-performance, open-source remote procedure call (RPC) framework developed by Google that uses HTTP/2 and protocol buffers to enable efficient, language-agnostic communication between services.
B. ASN.1
ASN.1 (Abstract Syntax Notation One) is a standardized, platform-independent notation used to define and encode complex data structures in telecommunications and cryptographic protocols, including X.509 certificates.
C. HPACK
HPACK is the dedicated header compression format used by HTTP/2 to efficiently encode and transmit HTTP header fields while maintaining security and performance.
D. SPDY
SPDY is an experimental, now-deprecated web protocol developed by Google to speed up and secure HTTP traffic, which heavily influenced the design of HTTP/2.
E. Google Cloud Pub/Sub
Google Cloud Pub/Sub is a fully managed real-time messaging service that enables asynchronous, scalable communication between independent applications and services.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
