OpenMetadata

The Open Context Layer for AI

The largest and fastest-growing open-source project for AI context, data cataloging, and metadata management.

OpenMetadata is the open platform for trusted data context, organizational memory, and business semantics for every data user, AI assistant, and agent.

OpenMetadata connects technical metadata, data quality signals, lineage, column-level lineage, ownership, usage, policies, conversations, memories, glossaries, classifications, metrics, domains, data contracts, and data products into a unified metadata knowledge graph. With 130+ connectors, open metadata standards, semantic search, APIs, SDKs, and an MCP server, OpenMetadata gives every user and AI system the governed context it needs to discover, understand, trust, remember, and use data.

AI does not need another raw database connector. AI needs context + memory.

OpenMetadata: The Open Context Layer for AI

OpenMetadata provides the context AI needs to know:

what data exists
what it means
who owns it
how it is used
where it came from
where it flows
whether it is fresh, tested, certified, and trusted
which business concepts, classifications, glossary terms, policies, contracts, and data products apply
what downstream dashboards, pipelines, metrics, ML models, and applications depend on it
what conversations, decisions, assumptions, and memory nuggets have already been captured about it

Why OpenMetadata for AI?

AI systems need more than data access. They need governed context, business meaning, trust signals, lineage, usage, ownership, standards, and organizational memory.

A direct connection to a warehouse, lake, dashboard, or pipeline exposes raw structures. It does not tell an AI assistant what the data means, whether it is certified, who owns it, which policies apply, what contract governs it, what breaks if it changes, or what the organization has already learned about it.

OpenMetadata is the open context layer that gives every data user and AI agent the full picture of enterprise data.

OpenMetadata brings together five capabilities:

Context — technical, operational, trust, usage, and lineage metadata from across the data ecosystem.
Semantics — business meaning through glossaries, metrics, classifications, domains, policies, ontologies, and data products.
Knowledge Graph — relationships connecting assets, columns, people, teams, quality, lineage, policies, memories, contracts, and business concepts.
Memory — conversations, AI threads, decisions, assumptions, runbooks, remediation notes, and reusable memory nuggets that preserve tribal knowledge.
Activation — MCP, Semantic Search, APIs, SDKs, events, and workflows that make context usable by AI assistants, agents, applications, and humans.

With OpenMetadata, users and AI agents can answer:

What does this metric mean and how is it calculated?
Which datasets power this dashboard?
Who owns this data product?
Which data contract applies?
Is this dataset fresh, tested, certified, and trusted?
Which downstream dashboards, pipelines, or ML models are affected by this column change?
Which columns contain sensitive customer information?
Which glossary terms, policies, standards, and business concepts apply?
What decisions, assumptions, incidents, or conversations have already been captured about this asset?

The Context OpenMetadata Connects

OpenMetadata collects and connects the context AI needs to reason safely over enterprise data.

Context type	What OpenMetadata captures	Why it matters for AI
Technical metadata	Databases, schemas, tables, columns, topics, dashboards, charts, pipelines, APIs, search indexes, ML models, storage assets, data types, constraints, descriptions, joins, sample queries, service metadata, owners, teams, usage, domains, and data products	Helps AI discover what exists and understand how assets are structured
Quality and trust	Test cases, test suites, freshness checks, volume checks, null, uniqueness, distribution, custom tests, profiling results, observability signals, incidents, alerts, and quality history	Helps AI avoid treating every dataset as equally trustworthy
Lineage and impact	Upstream and downstream lineage, table lineage, column-level lineage, dashboard lineage, pipeline lineage, metric lineage, ML model lineage, API and topic dependencies, and OpenLineage events	Helps AI explain where data came from, where it flows, and what changes may break
Semantics	Glossaries, business terms, synonyms, related terms, metrics, KPIs, classifications, tags, domains, data products, policies, personas, lifecycle states, and ontologies	Helps AI map technical names to business meaning
Governance	Owners, stewards, teams, policies, roles, classifications, access context, certification, review workflows, lifecycle states, and data contracts	Helps AI act with policy-aware context
Memory and tribal knowledge	Conversations, AI threads, decisions, assumptions, runbooks, remediation notes, incident learnings, and reusable memory nuggets attached to assets, users, teams, data products, and agent workflows	Helps humans and agents inherit what the organization already learned instead of rediscovering it in every conversation
Standards and interoperability	DCAT, DPROD, PROV-O, OpenLineage, ODCS, RDF/OWL, JSON-LD, SHACL, JSON Schema, APIs, events, and metadata schemas	Helps context move across tools, agents, catalogs, contracts, and knowledge graphs

Architecture: Context + Memory Graph

How OpenMetadata Works

OpenMetadata is built around an open, schema-first metadata graph.

Collect metadata from warehouses, lakes, BI tools, pipelines, ML platforms, messaging systems, storage systems, APIs, search systems, SaaS applications, metadata systems, documents, conversations, and agent workflows through 130+ connectors, ingestion APIs, events, and SDKs.
Normalize metadata with open schemas and standards so every asset, relationship, policy, contract, lineage event, and memory can be represented consistently.
Connect technical metadata, quality signals, lineage, ownership, usage, policies, conversations, memories, semantics, domains, contracts, and data products into one graph.
Preserve Memory by turning conversations, AI threads, decisions, assumptions, runbooks, and remediation notes into reusable governed memory nuggets tied to data assets and business context.
Govern context with open standards, classifications, policies, roles, data quality, review workflows, data contracts, and stewardship.
Activate that context through Semantic Search, MCP, APIs, SDKs, events, webhooks, metadata applications, and AI workflows.

Memory is part of the architecture, not a side channel. It lets engineers use APIs, SDKs, MCP, or AI workflows to preserve conversational context and convert tribal knowledge into reusable organizational knowledge.

Context Graph, Semantics, and Memory

OpenMetadata Context Graph

The OpenMetadata graph does not only store data assets. It stores the relationships between assets, columns, owners, teams, policies, quality tests, lineage, classifications, glossary terms, metrics, domains, data contracts, data products, conversations, and memory nuggets.

Example relationships:

Table               ──hasColumn────────────> Column
Column              ──classifiedAs─────────> PII
Column              ──represents───────────> Customer Identifier
Table               ──ownedBy─────────────> Data Engineering Team
Table               ──partOf──────────────> Customer 360 Data Product
Dashboard           ──dependsOn───────────> Table
Metric              ──definedBy───────────> Glossary Term
Pipeline            ──produces────────────> Table
Column              ──flowsTo─────────────> Column
Test Case           ──validates───────────> Table
Policy              ──governs─────────────> Classification
Data Contract       ──appliesTo───────────> Table
OpenLineage Event   ──updatesLineageFor───> Pipeline
Agent Conversation  ──capturedAs──────────> Memory 
Memory              ──informs─────────────> Data Product
Memory              ──documentsDecisionFor> Metric
Memory              ──attachedTo──────────> Table / Column / Topic / Dashboard / Pipeline / API

This graph gives AI systems the relationships, meaning, memory, and governance they need to reason across the data estate.

Memories: Organizational Context for Humans and Agents

Memory Primitives

Memories preserve the important context that usually disappears inside chats, tickets, meetings, notebooks, and AI agent threads.

A memory is an open, governed OpenMetadata entity that can be tied to data assets, users, teams, threads, domains, data products, metrics, policies, incidents, and workflows. Engineers can capture and retrieve memories through APIs, SDKs, MCP, chat, or AI applications.

Use memories to preserve:

why a metric changed
why a column was renamed
what assumption was used in an analysis
which remediation fixed a data quality issue
which dashboard or data product a decision applies to
what an AI agent learned while investigating an incident
what a domain expert explained in a conversation

Memories unlock tribal knowledge by making it reusable, governed, searchable, and available to every human, assistant, and agent that touches your data.

MCP, Semantic Search, APIs, AI SDK, and Memory

OpenMetadata makes context actionable through AI- and developer-friendly interfaces.

MCP Server

OpenMetadata includes an MCP server that lets MCP-compatible assistants and agents interact with the metadata graph through natural language.

AI assistants can use OpenMetadata MCP to:

search metadata
run semantic search
retrieve entity details
inspect lineage
understand data contracts and policy context
retrieve or preserve memory nuggets
update descriptions, tags, owners, and other metadata
create glossary terms and lineage
list and create data quality tests
analyze root causes of data quality failures

Get started: OpenMetadata MCP Server Documentation

Semantic Search

Semantic Search lets users and AI assistants find data assets by meaning, not only exact keywords.

Find trusted customer purchase datasets with known data quality issues and recent remediation notes.

OpenMetadata can surface conceptually related assets, metrics, glossary terms, data products, memory nuggets, and governance context even when names differ across domains, tools, and teams.

APIs, SDKs, Events, and Webhooks

OpenMetadata exposes APIs, SDKs, events, and webhooks so teams can ingest, update, search, subscribe to, and automate metadata across their ecosystem.

Developers can use the AI SDK to build custom AI applications that use OpenMetadata context and memory programmatically.

Use It From Code

Two packages, depending on what you're building.

Goal	Package	Install
Read/write metadata, lineage, glossary, quality	`openmetadata-ingestion`	`pip install "openmetadata-ingestion"`
Give an LLM or agent governed access (MCP, LangChain)	`data-ai-sdk`	`pip install data-ai-sdk`

Also available: @openmetadata/ai-sdk (TypeScript), org.open-metadata:ai-sdk (Java).

Python SDK — connect and read metadata

Match the SDK version to your server version.

from metadata.generated.schema.entity.data.table import Table
from metadata.generated.schema.entity.services.connections.metadata.openMetadataConnection import (
    OpenMetadataConnection, AuthProvider,
)
from metadata.generated.schema.security.client.openMetadataJWTClientConfig import (
    OpenMetadataJWTClientConfig,
)
from metadata.ingestion.ometa.ometa_api import OpenMetadata

metadata = OpenMetadata(OpenMetadataConnection(
    hostPort="http://localhost:8585/api",
    authProvider=AuthProvider.openmetadata,
    securityConfig=OpenMetadataJWTClientConfig(jwtToken="<your-token>"),
))
assert metadata.health_check()

table = metadata.get_by_name(entity=Table, fqn="sample_data.ecommerce_db.shopify.raw_product_catalog")
print(table.description, [c.name.root for c in table.columns])

Entities are hierarchical — a Table belongs to a Schema, which belongs to a Database, which belongs to a DatabaseService. Every entity references its parent by fullyQualifiedName.

AI SDK — give an agent governed context via MCP

OpenMetadata exposes an MCP server at /mcp. Unlike generic connectors that only read raw database schemas, it exposes semantic search, lineage traversal, glossary/classification, and metadata mutations as tools any LLM can call.

from ai_sdk import AISdk, AISdkConfig

client = AISdk.from_config(AISdkConfig.from_env())

# Convert MCP tools to LangChain format — one line
tools = client.mcp.as_langchain_tools()

# Or call a tool directly
result = client.mcp.call_tool("search_metadata", {"query": "customers"})

Works with LangChain and OpenAI function calling out of the box.

What You Can Build

AI Data Discovery

Ask natural-language questions over the metadata graph and find relevant assets even when names and keywords do not match exactly.

Trusted AI Assistants

Ground AI responses in governed metadata: owners, descriptions, glossary terms, classifications, quality, freshness, usage, lineage, policies, contracts, and memory.

Agent Memory and Tribal Knowledge

Capture conversations, decisions, assumptions, runbooks, and agent learnings as governed memory nuggets that can be reused by every data user and AI agent.

Impact Analysis Agents

Ask what will break if a table, column, pipeline, dashboard, metric, ML feature, contract, or data product changes.

Governance Automation

Use agents to suggest descriptions, assign glossary terms, identify sensitive data, propose ownership, enforce contract context, and manage stewardship workflows.

Data Quality Automation

Use AI workflows to create tests, summarize failures, identify root causes, preserve remediation memory, and recommend next actions.

Developer and Coding Agent Workflows

Connect coding agents to OpenMetadata so they understand schemas, owners, lineage, business definitions, quality expectations, contracts, and memory before generating SQL, dbt models, documentation, tests, migration plans, or impact analysis.

Open Standards and Interoperability

OpenMetadata is built on open metadata standards.

OpenMetadata Standards is the open-source home for schemas, APIs, ontologies, event models, and semantic specifications behind OpenMetadata.

It provides:

700+ JSON Schemas for metadata entities, APIs, configurations, events, and relationships
RDF/OWL ontologies for semantic web, linked data, and knowledge graph use cases
SHACL shapes for validation
JSON-LD contexts for semantic interoperability
standards for governance, lineage, quality, observability, teams, users, roles, policies, events, contracts, and data products

OpenMetadata supports and aligns with the standards that matter for AI context and data ecosystems:

Standard	How OpenMetadata uses it
DCAT / DPROD	Represents catalog and data-product context in interoperable semantic models, including datasets, data services, distributions, domains, owners, input and output datasets, lifecycle state, purpose, and policies.
PROV-O	Uses W3C provenance semantics for lineage, generated/derived data, agents, activities, ownership, and explainable context.
OpenLineage Support	Accepts and connects OpenLineage-compatible lineage events so pipeline execution metadata can enrich the broader OpenMetadata graph.
ODCS Support	Supports Open Data Contract Standard 3.1 for interoperable data contracts, contract import/export, schema expectations, quality rules, SLAs, support channels, roles, and producer-consumer agreements.
RDF/OWL, JSON-LD, SHACL	Makes metadata graph-friendly, semantically interoperable, and validatable for linked data, knowledge graph, and AI use cases.
JSON Schema, APIs, Events	Keeps metadata portable, automation-friendly, and extensible across tools, agents, and custom applications.

These standards make OpenMetadata a foundation for interoperable semantic metadata, linked data, data products, data contracts, lineage, provenance, and enterprise knowledge graphs.
