Rego

Rego is a term with several distinct uses in technology, geography, and personal names. It may refer to a declarative policy language used with Open Policy Agent, a neighborhood in New York City, and a Portuguese-origin surname or given name.

In technology, Rego is the policy language of Open Policy Agent (OPA). It is a high-level, declarative language designed to express policies as rules that evaluate data and return decisions. Policies in Rego are written as rules, with support for variables, sets, comprehensions, and built-in functions. Rego policies typically operate on input data in JSON form and are used to enforce access control, data filtering, and admission control in cloud-native environments, including Kubernetes-based systems and microservices architectures. OPA evaluates Rego policies and returns decisions to the requesting service or policy enforcer; many tools and platforms integrate Rego to centralize policy decisions.

Rego Park is a residential neighborhood in the Queens borough of New York City. The area developed in the 20th century and is known for a mix of housing and commercial corridors. It lies within the broader New York City metropolitan area and is served by local transit options.
