A free open source cross-platform C++ library for parsing ODB++ Design archives, accessing their data, and building net list product models. Exposed via a REST API packaged inside of a Docker image.
Sounds great! Now how do I build and run it?
Documentation for the currently-released version of the source code is available here.

OdbDesign ODB++ parser is differentiated from other offerings by these key features:
- Performance
- Cross-Platform Flexibility
- Expertise
- Security
OdbDesign is implemented in C++ and is designed and optimized to be fast. Unlike higher-level languages that use interpreters or virtual machines, that means it is compiled into native code for your machine, whether your platform is Windows, Linux, or Mac.
The parser is also multi-threaded to take advantage of modern multi-core CPUs.
The library itself can run directly on all major platforms (i.e. Windows, Linux, and Mac) and also exposes a REST API so that parsed data can be accessed from any application or programming language that can connect to a REST API. The REST API and library are also exposed via a Docker image that can be run on any platform that supports Docker.
Both options support running the parser on a different machine than the one running the application that needs the parsed data. This allows the parser to be run on a high-performance server or workstation while the application that needs the data runs on a low-power device like a Raspberry Pi, mobile device, or the web.
The maintainer has well over a decade of experience in the PCB Manufacturing and hardware industry. Specifically he has worked on the development of ODB++ parsing and viewer applications for some of the established key players in the industry. Time spent working under the designer of the ODB++ specification has given him a unique perspective on the ODB++ format and how it is used in the industry. This experience is also leveraged to make the parser as fast and efficient as possible.
All code, dependency packages, and Docker images are scanned for security vulnerabilities, using extended security scanning rule profiles (these are more secure than the default base scanning rule profiles).
The project has earned a high score on the OpenSSF Security Scorecard. Details can be seen in the Project Security section below.
It is built using the latest available version of the C++ standard and is compiled with the latest available compiler versions. The parser is also built using the latest available versions of all of its dependencies and is regularly updated to use the latest versions of those dependencies as they are released.
These checks are run against all branches starting with development, so there is no chance of a security vulnerability being introduced into the main and release branches. Docker's Scout Suite is used to scan the Docker image for security vulnerabilities, and GitHub's CodeQL is used to scan the code for security vulnerabilities.
The diagram describes the current state of parser implementation and data availability. Green color describes areas of the ODB++ archive file that are implemented and have their data available for use. Red color describes areas that are not parsed so their data is not yet available. All areas of the file are now parsed, and have their data available for use.

OpenSSF Security Scorecard assesses open source projects for security risks through a series of automated checks.
The majority of tested projects have a much lower score, so OdbDesign's 7.8 score represents a remarkably high level of security.

The OdbDesign parser is built as a C++ shared library on all three platforms. An executable running the server links to the library and provides the REST API for accessing the data the library parses. The REST API server can be run by invoking the executable directly or by running the Docker image. The server executable and library can be run on Windows, Linux, or MacOS and the Docker image can be run on any platform that supports Docker.
Documentation for the currently-released version of the source code is available here.

FileModel vs. ProductModel...
There are three different ways to use the project. You can:
- Build the C++ shared library and use it in your own application
- Build the C++ library and REST API server application and then run the application
- Run the REST API server (which contains the library inside) from the Docker image.
The instructions for building the C++ shared library and application are below in the Building from Source section. The instructions for running the application or REST API server are here.
The C++ application REST API server can be run by executing the OdbDesignServer or OdbDesignServer.exe executable (depending on your platform).
The executable can be found in the following directory:
~/src/OdbDesign/out/build/x64-release(Linux/MacOS)C:\Users\<YourName>\Source\OdbDesign\out\build\x64-release(Windows)
See the Building from Source section for more details on building the C++ application and the build output directory.
If successful, the REST API server will be running and listening on port 8888. You can access the REST API at http://localhost:8888.
From the root of the source directory run:
$ docker compose up
If successful, the REST API server will be running and listening on port 8888. You can access the REST API at http://localhost:8888. The Swagger UI is available at http://localhost:8080/swagger.
Documentation for the currently-released version of the source code is available here.
If you are building on Windows and have a modern version of Visual Studio installed then all of the dependencies listed below are already installed on your system (except for maybe Docker). You can skip to the next section.
If you are building on a Linux system then the dependencies listed below can be installed using your package manager. For example on Ubuntu you can install them (except for vcpkg and Docker) using the following command:
$ sudo apt install git cmake ninja-build build-essential
- git (install instructions for your platform)
- vcpkg (install instructions for your platform)
- CMake (install instructions for your platform)
- Ninja (install instructions for your platform)
- Docker (install instructions for your platform) (optional)
git, CMake, and ninja can all be installed via the sudo apt install command listed above. vcpkg can be installed by following the instructions below. Docker is optional but can be installed via the following command:
$ sudo apt install docker.io docker-compose-v2
$ git clone https://github.com/microsoft/vcpkg
$ .\vcpkg\bootstrap-vcpkg.batThen add the following line to your shell profile (e.g. ~/.bashrc, ~/.zshrc, etc.):
export VCPKG_ROOT=/path/to/vcpkg
Make sure to restart your shell or source the profile after adding the line.
source ~/.bashrc
Get the source code by cloning the GitHub repository:
$ git clone https://github.com/nam20485/OdbDesign.gitOpen your favorite terminal and change to the directory where you cloned the source code. This should be something similar to one of the below depending on your platform and where you cloned the source code:
~/src/OdbDesign(Linux/MacOS)C:\Users\<YourName>\Source\OdbDesign(Windows)
Then run the commands from one or more of the sections below, based on what you would like to build...
- Open the directory in Visual Studio (this will open the directory as a CMake project)
- Select a Configuration preset:
x64 Releasex64 Debug
- Select a target:
OdbDesign.dll(parser shared library)OdbDesignServer.exe(REST API server executable)
- Build (i.e. Build->Rebuild All or CTRL+SHIFT+B)
$ cmake --preset x64-debug
$ cmake --build --preset x64-release$ cmake --preset linux-debug
$ cmake --build --preset linux-release
This builds the C++ shared library and the REST API server executable. See the Running the C++ Application section for more details.
The build output can be found in the following directory:
~/src/OdbDesign/out/build/x64-release(Linux/MacOS)C:\Users\<YourName>\Source\OdbDesign\out\build\x64-release(Windows)
The
x64-releasedirectory will be different if you selected a different configuration preset (x64-releasevs.x64-debugorlinux-releasevs.linux-debug). Thex64-releasedirectory will contain the shared library and the server executable. Make sure to copy the dependencies (.dll files on Windows, .so files on Linux, .dylib files on MacOS) to the same directory as the executable if you want to copy it somewhere else.
From the root of the source directory...
$ docker compose upThis builds the Docker image and runs it. See the Running the REST API Server section for more details.
There are three separate interfaces that allow use of the library in other applications.
Build the C++ shared library and link it into your own C++ application. See the Building from Source section for more details on building it.
Run the REST API server and access the data via the REST API. See the Running the REST API Server section for more details on running it.
Data objects returned from the parser library support serialization to and from Google Protobuf protocol buffers. This allows the data to be easily shared with other applications and programming languages that support protocol buffers. Google Protobuf is a highly optimized binary encoding so it is fast and small.
The protocol buffer definitions are included in the library so they can be used to generate code for other languages - currently C++ bindings are built and used in the library.
