Application Research

aid: application-research
name: Application Research
description: >-
  Application Research is a topic collection focused on specifications for declaring
  application service integration dependencies. It covers five specification formats:
  Score (platform-agnostic workload specs), Cloud Native Application Bundle (CNAB),
  Open Component Model (OCM), Open Resource Discovery (ORD), and Radius — all aimed
  at enabling deployment teams to understand what services (APIs, databases, caches,
  message buses, blob stores) an application requires.

  - name: Score Workload Specification API
    description: >-
      Score is a platform-agnostic workload specification that enables developers to
      define their workloads once and deploy them across multiple platforms including
      Kubernetes, Docker, and Helm. The API manages workload spec lifecycle and platform
      translations.
