How this entity was disambiguated

This entity first appeared as the object of triple T9712770 — 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: OCI runtime specification
Context triple: [Podman, supportsStandard, OCI runtime specification]

A. Container Runtime Interface
The Container Runtime Interface (CRI) is a plugin API in Kubernetes that allows the orchestration system to interact with and manage different container runtimes in a standardized way.
B. runc
runc is a lightweight, low-level command-line tool and reference implementation for running Open Container Initiative (OCI) containers.
C. CRI-O
CRI-O is a lightweight, Kubernetes-focused container runtime that implements the Container Runtime Interface to run Open Container Initiative (OCI) compatible containers.
D. containerd
containerd is an industry-standard, CNCF-hosted container runtime that manages the complete container lifecycle on Linux and Windows, widely used as the core runtime component in modern container platforms.
E. Container-optimized OS
Container-optimized OS is a lightweight, security-focused operating system from Google designed specifically for efficiently running Docker containers on Google Cloud infrastructure.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
