# olca-proto

`olca-proto` is a [Protocol Buffers](https://developers.google.com/protocol-buffers)

implementation of the [olca-schema format](https://github.com/GreenDelta/olca-schema).

It also defines a [gRPC](https://grpc.io/) service interface for calling

[openLCA](https://www.openlca.org) functions.

## Usage

If you use Maven, just add the following dependency:

```xml

  org.openlca

  olca-proto

  2.0.0

```

For the gRPC service interface, add this:

```xml

  org.openlca

  olca-grpc

  2.0.0

```

## Building from source

The Java source code is generated from proto3 files in the `proto` folder of

this project. The `olca.proto` file contains the definition of the openLCA

schema format and is generated via the `osch` tool of the [olca-schema project](

https://github.com/GreenDelta/olca-schema).

To generate the Java source code, we use the

[protobuf-maven-plugin](https://github.com/xolstice/protobuf-maven-plugin):

```bash

mvn compile

```

You need to have the `protoc` compiler with the gRPC plugin for Java installed.

One way to install it, is to just put the binaries of these tools into your

system path. The `protoc` binary can be downloaded from its GitHub release page:

https://github.com/protocolbuffers/protobuf/releases. The gRPC Java plugin

can be downloaded from the Maven Central Repository:

https://repo1.maven.org/maven2/io/grpc/protoc-gen-grpc-java/. You may need to

rename the plugin to `protoc-gen-grpc-java` and set the executable flags:

```bash

chmod +x protoc-gen-grpc-java

```
