jEAP Common Message Type Registry

This repository is the jEAP Common Message Type Registry: a Git-based catalog of the message types (events and commands) produced or consumed by jEAP services and libraries such as the jEAP Process Context Service, the jEAP Message Exchange Service and the jEAP Reaction Observer. Each message type is described by a JSON type descriptor plus one or more Avro .avdl schemas under descriptor/<system>/.... A Maven build validates the registry and publishes a generated Java message-type artifact per type and version, which consuming services pull in as ordinary Maven dependencies.

• A versioned, design-time home for jEAP message-type descriptors and their Avro value/key schemas
• One JSON descriptor per type with name, definingSystem, scope, topic and versions
• A validation build that keeps the registry consistent and forbids changing released schema versions
• Publishing of generated Java bindings via the jeap-messaging Avro Maven plugin (compile-message-types / deploy-message-type-artifacts)
• Shared records under _shared / _common for keys and references reused across types and systems

Repository structure

This is a single-module Maven project (packaging=pom); the pom only drives the validation and publishing build. The actual content lives under two directories:

descriptor/<system-lowercase>/event|command/<typename-lowercase>/   # descriptors + .avdl schemas
descriptor/_shared/ , descriptor/_common/                           # shared / common schemas
schema/                                                             # JSON schemas for the descriptors (IDE support)
