[![CI](https://github.com/ModernRelay/omnigraph/actions/workflows/ci.yml/badge.svg)](https://github.com/ModernRelay/omnigraph/actions/workflows/ci.yml)

Typed graph engine built for reasoning paths, not just storage.  
Git-style workflows, schema-as-code graph modeling, S3-optimized.

## Use Cases

- On-prem & hybrid context graphs
- Backbone for multi-agentic research
- Enterprise knowledge systems

## Quick Install

```bash
curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/install.sh | bash
```

This installs `omnigraph` and `omnigraph-server` into `~/.local/bin` from
published release binaries. 

Or install with Homebrew:

```bash
brew tap ModernRelay/tap
brew install ModernRelay/tap/omnigraph
```

For starter graphs and agent skills to bootstrap and operate Omnigraph, see [`ModernRelay/omnigraph-starters`](https://github.com/ModernRelay/omnigraph-starters).

## One-Command Local RustFS Bootstrap

```bash
curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/local-rustfs-bootstrap.sh | bash
```

That bootstrap:

- starts RustFS on `127.0.0.1:9000`
- creates a bucket and S3-backed repo
- loads the checked-in context fixture
- launches `omnigraph-server` on `127.0.0.1:8080`

Docker must be installed and running first.

The RustFS bootstrap prefers the rolling `edge` binaries and only falls back to
source builds when release assets are unavailable.

If a previous run left objects under the same repo prefix but did not finish
initializing the repo, rerun with `RESET_REPO=1` or set `PREFIX` to a new
value.

## Omnigraph CORE

- Typed schema, typed queries, and typed mutations
- Schema-as-code, query validation and linting
- Git-style graph workflows: branches, commits, merges, and transactional runs
- Local, on-prem & cloud S3-native storage with snapshot-pinned reads
- Graph traversal + text, fuzzy, BM25, vector, and RRF search in one runtime
- Policy-as-code for server-side access control
- Single CLI for multiple deployments

## Common Commands

The same URI works for local paths, `s3://…`, or `http://host:port`.

```bash
omnigraph init   --schema ./schema.pg ./repo.omni
omnigraph load   --data   ./data.jsonl ./repo.omni
omnigraph read   --query  ./queries.gq --name get_person --params '{"name":"Alice"}' ./repo.omni
omnigraph change --query  ./queries.gq --name insert_person --params '{"name":"Mina"}' ./repo.omni
omnigraph branch create --from main feature-x ./repo.omni
omnigraph branch merge  feature-x --into main ./repo.omni
```

See [docs/cli.md](docs/cli.md) for schema apply, snapshots, ingest, runs, and policy commands.

## Build And Test

```bash
cargo build --workspace
cargo check --workspace
cargo test --workspace
```

Notes:

- Rust stable toolchain, edition 2024
- CI runs `cargo test --workspace --locked`
- Full CI and some local test flows require `protobuf-compiler`
- S3 integration tests expect an S3-compatible endpoint such as RustFS

## Workspace Crates

- `crates/omnigraph-compiler`: shared schema/query parser, typechecker, catalog, and IR lowering
- `crates/omnigraph`: storage/runtime, branching, merge, change detection, and query execution
- `crates/omnigraph-cli`: CLI for init/load/ingest/read/change/branch/snapshot/export/policy operations
- `crates/omnigraph-server`: Axum HTTP server for remote reads, changes, ingest, export, branches, commits, and runs

Please open an issue, spec, or design discussion before sending large code
changes. Design feedback and concrete problem statements are the fastest way to
collaborate on the roadmap.
