Milo is an open-source implementation of OPC UA (currently targeting 1.03). It includes a high-performance stack (channels, serialization, data structures, security) as well as client and server SDKs built on top of the stack.

## Maven

### Building Milo

**Using JDK 8**, run `mvn clean install` from the project root.

To maintain compatibility with Java 8 it is recommended that you build using JDK 8, however the library is runtime compatible with versions 8 and later (e.g. JDK 11, JDK 17).

### Releases

Releases are published to Maven Central and snapshots to Sonatype.

#### OPC UA Client SDK

```xml

    org.eclipse.milo

    sdk-client

    0.6.15

```

#### OPC UA Server SDK

```xml

    org.eclipse.milo

    sdk-server

    0.6.15

```

Referencing a `SNAPSHOT` release requires the Sonatype snapshot repository be added to your pom file:

```xml

    oss-sonatype

    oss-sonatype

    https://oss.sonatype.org/content/repositories/snapshots/

```

## Public Demo Server

An internet-facing demo server is accessible at `opc.tcp://milo.digitalpetri.com:62541/milo`.

It accepts both unsecured and secured connections. Before connecting with security you must upload your client's DER-encoded X509 certificate using the form at http://milo.digitalpetri.com.

Authenticate anonymously or with one of the following credential pairs:

- `user1` / `password`

- `user2` / `password`

- `admin` / `password`

The code powering the demo server is available here: https://github.com/digitalpetri/opc-ua-demo-server
