UModel

中文版本：README_CN.md

UModel (Unified Model) is a vendor-neutral semantic runtime for enterprise AI, data governance, and operational intelligence. It turns fragmented schemas, entities, business objects, telemetry links, and topology relations into workspace-scoped graph context that humans, systems, and AI agents can understand and use through one local service.

With UModel, you can:

• Author and import model packs that define enterprise objects, operational objects, datasets, links, storage, and topology semantics.
• Write CMS 2.0 compatible runtime entities and relations.
• Query models, entities, and topology through one SPL surface: .umodel, .entity, and .topo.
• Explore the workspace through a local Web UI.
• Connect agent clients through AgentGateway and MCP.
• Use public REST, CLI, and SDK contracts without depending on server internals.

Why UModel

• Accelerate enterprise AI at scale. A unified semantic standard helps AI models understand data meaning across platforms, departments, tools, and domains, improving the path to intelligent operations, customer service, analytics, prediction, and agent workflows.
• Reduce data governance cost. A shared language for multi-source enterprise data frees data teams from repetitive metric alignment, field translation, and context reconstruction, so more effort goes into extracting value from data.
• Preserve vendor neutrality and choice. UModel is independent of any single platform, data tool, observability stack, or AI vendor, helping organizations avoid semantic lock-in while building digital infrastructure.
• Build an enterprise semantic operating system. UModel moves beyond a passive data dictionary toward a live, programmable semantic runtime that AI agents can query, reason over, and use as shared context for future multi-agent collaboration.

Project Scope

This repository includes the local UModel service, umctl CLI, MCP server, OpenAPI contract, React Web UI, generated SDK assets, example packs, Docker/Compose assets, and test suites.

The open-source core focuses on local operation, public contracts, semantic modeling, agent integration, and contributor-friendly extension points. Cloud-hosted control planes, multi-tenant authorization, Aliyun internal frontend packages, and domain-specific read APIs outside Query Service are outside the public core.

Five-Minute Quick Start

Requirements:

• Go 1.22 or newer.
• Make.
• Node.js 22 or newer for the Web UI.
• pnpm 9 or newer is preferred; corepack or npm exec fallback is supported by the Makefile.

Check the local toolchain:

make check-env

Start the API and Web UI with a preloaded demo workspace:

make quickstart

make quickstart starts a local API, starts the Web UI, preloads the demo workspace with GRAPHSTORE=memory, and leaves no local demo data behind after the process stops.

Next steps:

• Open http://localhost:5173, select demo, and inspect the workspace through Explorer, Query, Data Store, and Agent views.
• Integrate an agent through AgentGateway or MCP. Start with umctl agent discover demo, then connect an MCP client through umodel-mcp.
• Query models, entities, and topology through CLI or REST using Query Service.

Stop local services:

make stop-all

Architecture

UModel runs as a local service around one workspace-scoped object graph:

• Model packs define the object vocabulary: EntitySets, datasets, links, storage, and relation semantics.
• EntityStore writes runtime entities and topology relations that instantiate the model.
• Query Service is the unified read surface for .umodel, .entity, and .topo.
• AgentGateway and MCP expose discovery, resources, query examples, and safe tools for agent clients.
• Web UI, CLI, REST, and SDK clients operate against the same public contracts.
