ManuScript

The unified event schema for distributed collaboration at scale. ManuScript is the Protocol Buffer schema system that serves as the single source of truth for all events flowing through the Materi collaboration platform. It enables type-safe, auditable, and replayable event processing across 7+ microservices handling 95B+ events per year.

Features

✨ Production Ready

Compiled Protocol Buffers with Go, TypeScript, and Python bindings
Type-safe event definitions with protoc
50+ domain-specific event types across 8 domains
Beautiful TUI explorer for schema introspection
Published packages: github.com/materi/domain/proto (Go), @materi/proto (npm), materi-proto (PyPI)

🎯 Competitive Advantages

Unified Schema: Single source of truth vs fragmented implicit schemas
Introspectable Metadata: Custom proto options enable runtime inspection
Deterministic Replay: Complete event history replay for debugging
Forensic Auditing: Immutable audit trails with strong consistency guarantees
Distributed Tracing: Built-in trace correlation across services
Causal Ordering: Hybrid Logical Clock (HLC) for deterministic ordering

🔒 Designed for Scale

Supports 95B+ events/year across 7+ services
Redis stream integration for high-throughput publishing
Consumer group management with offset tracking
30-90 day retention policies with compliance metadata

Installation

Go

go get github.com/materi/domain/proto

import (
    "github.com/materi/domain/proto"
    envelope "github.com/materi/domain/proto/materi/v1/envelope"
    user "github.com/materi/domain/proto/materi/v1/user"
)

// Create an event
event := &user.UserCreatedEvent{
    UserId: "user-123",
    Email:  "[email protected]",
    Name:   "Alice",
}

TypeScript / JavaScript

npm install @materi/proto
# or
yarn add @materi/proto

import { UserCreatedEvent, DomainEvent, Status } from '@materi/proto';

const event: UserCreatedEvent = {
    userId: 'user-123',
    email: '[email protected]',
    name: 'Alice',
    createdAt: new Date(),
};

// Serialize to bytes
const bytes = UserCreatedEvent.encode(event).finish();

Python

pip install materi-proto

from materi_proto import UserCreatedEvent, DomainEvent, Status

event = UserCreatedEvent(
    user_id="user-123",
    email="[email protected]",
    name="Alice",
)

# Serialize to bytes
data = event.SerializeToString()

)

func main() {
    // Create a schema registry
    registry := schema.NewSchemaRegistry()

    // Get all events
    events := registry.GetAllEvents()

    // Find events by domain
    userEvents := registry.GetEventsByDomain("user")

    // Find events consumed by a specific service
    apiEvents := registry.GetEventsByConsumer("API")

    // Get schema statistics
    stats := registry.GetStats()
    println("Total events:", stats.TotalEvents)
    println("Auditable rate:", stats.AuditableRate * 100, "%")

    AggregateId    string
    AggregateType  string
    EventType      string
    Data           []byte
    Timestamp      int64

    // Tracing fields
    TraceId        string  // W3C trace context
    SpanId         string  // Current span
    ParentSpanId   string  // Parent span
    CorrelationId  string  // Causality tracking
}

Integrates with:

Folio (centralized observability hub)
Prometheus (metric collection)
Jaeger (distributed tracing)
