A Registry System is a data management system that maintains a central directory of information and metadata about assets, often for the purpose of discovery and retrieval.

  • Context:
    • It can (typically) store metadata and information about assets, rather than the assets themselves.
    • It can be used to discover and retrieve assets from a distributed environment.
    • It can provide access control to manage user permissions and visibility of registered assets.
    • It can (often) be used in service-oriented architectures for service discovery.
    • It can support integration with other systems through APIs.
  • Example(s):
    • Source Code Registry: Stores source code repositories, and may include features like code review, issue tracking, and continuous integration.
    • Container Registry: Specifically for storing container images, such as Docker images. Includes features like image signing, vulnerability scanning, and integration with container orchestration systems.
    • Service Registry: Holds information about available services, their instances, and locations in a microservice architecture, enabling service discovery.
    • Package Registry: Stores packages that can be used as dependencies in software projects, along with handling versioning and dependencies.
    • Data Registry: Keeps metadata about datasets, storing information about the content, quality, and provenance of datasets, but not the data itself.
    • Device Registry: In the context of IoT (Internet of Things), a device registry manages and stores information about devices such as sensors, actuators, and other connected devices.
    • Schema Registry: Stores and tracks the versions of schemas used in a distributed data processing system, especially in event-driven architectures where schemas might evolve over time.
    • Health Information Registry: In healthcare, a registry is a collection of information about individuals, usually focused on a specific disease or condition. Includes features for aggregating and analyzing data for research purposes.
    • Asset Registry: In content management and digital asset management, an asset registry stores metadata about digital assets such as images, videos, and documents, and may include features for transforming and delivering assets.
    • Domain Name Registry: A database that contains information about domain names and their associated DNS information. Includes features for managing domain name lifecycles and DNS configurations.
    • Configuration Registry: Stores configuration information for systems and applications. Includes features for dynamic configuration updates and versioning.
  • Counter-Example(s):
    • A database that stores data records but does not provide metadata or discovery features.
