+# Event schema registry
+
+This repository is an example of how to make event schema registry for JSON schema events using only github. The general idea - how to share schemas across different services plus how to validate data for specific events.
+
+## Setup
+### Ruby
+Add this line into your Gemfile:
+
+```
+gem "schema_registry", git: "https://github.com/davydovanton/event_schema_registry.git"
+```
+
+## How to add a new event schema
+
+For example, you want to create `billing.refund` event. For make it happen you need:
+
+1. Create a new file `domain/event_name/version.json` in `schemas/` folder. For `billing.refund` it will be `schemas/billing/refund/1.json` (because all new events should be first version;
+2. Create a new json schema file like this:
+
+```
+{
+  "$schema": "http://json-schema.org/draft-04/schema#",
+
+  "title": "Billing.Refund.v1",
+  "description": "json schema for billing refund event (version 1)",
+
+  "definitions": {
+    "event_data": {
+      "type": "object",
+      "properties": {
+        // event specific information here
+      },
+      "required": [
+      ]
+    }
+  },
+
+  "type": "object",
+
+  "properties": {
+    "event_id":      { "type": "string" },
+    "event_version": { "enum": [1] },
+    "event_name":    { "type": "string" },
+    "event_time":    { "type": "string" },
+    "producer":      { "type": "string" },
+
+    "data": { "$ref": "#/definitions/event_data" }
+  },
+
+  "required": [
+    "event_id",
+    "event_version",
+    "event_name",
+    "event_time",
+    "producer",
+    "data"
+  ]
+}
+```
+
+## How to validate an event data by specific schema
+
+### Ruby
+
+For validating event data you need to use `SchemaRegistry#validate_event` method with following options:
+
+* `data` - event data
+* `name` - name of event which you will use for getting schema
+* `version` - version of event data schema (default `1`)
+
+Example:
+
+```ruby
+message = {
+  # ...
+}
+
+# will try to search `schemas/Billing/CompliteCycle/1.json` file
+result = SchemaRegistry.validate_event(data, 'Billing.CompliteCycle', version: 1)
+# will try to search `schemas/billing/complite_cycle/1.json` file
+result = SchemaRegistry.validate_event(data, 'billing.complite_cycle', version: 1)
+
+# After you can work with result object
+result.success?
+result.failure?
+result.failure
+```
+
+## How to use this library with producer
+### Option one: with event object
+```ruby
+result = SchemaRegistry.validate_event(event, 'billing.refund', version: 1)
+
+if result.success?
+  kafka.produce('topic', event.to_json)
+end
+```
+
+### Option two: with pure hash
+```ruby
+result = SchemaRegistry.validate_event(event, 'billing.refund', version: 1)
+
+if result.success?
+  kafka.produce('topic', event.to_json)
+end
+```
