This project is focused on supplying a reference implementation, both for supply-side and demand-side platforms, of the offline synchronization services specified in the OpenRTB Specification.

The goal and design of this work is to minimize the effort required by any DSP or SSP wishing to leverage the capabilities described in the spec.

You should be able to build the project by running 'mvn clean install' from the top-level directory. The project is structured in the following manner:

This directory is a maven project that produces a single jar file. This jar file contains all code that is shared between the demand-side and supply-side implementations (i.e. authentication/validation work, object models, etc.)

This directory contains a series of maven projects responsible for the DSP behavior of this specification. The sub-project artifact responsibilities include:

This project packages up a web archive (war) file, capable of being deployed in any standard JEE web container based upon the reference 'dsp-client' artifact provided with this implementation.

The contents of this package are purposefully minimized to the deployment artifacts necessary to deploy the war file.

This project produces a jar file containing the necessary logic for sending requests and receiving responses, including all message handling that is pertinent to the DSP.

This jar file represents standard logic that would be implemented by any DSP wishing to leverage this implementation.

All DSP specific logic (i.e. persisting the response data, retrieving advertiser information, etc.) is delegated to the 'dsp-client' via the 'dsp-intf'.

This package is the contract and set of interfaces between the message handling code located in the 'dsp-core' and a DSP's specific internal representation of that data.

This package is an example implementation of the 'dsp-intf' to satisfy the following:

1. Integration testing between the 'dsp-web' and 'ssp-web' projects.
2. Provide a framework for other DSPs to leverage this specification more quickly by allowing the DSP to focus on the integration aspects of the specification with their own specific platform.

As a result of requirement (1) above, this package must be capable of working in concert with the 'ssp-client' described below.

Similar to the demand-side module, this directory contains a series of maven projects responsible for the SSP behavior described in the specification. The sub-module artifact responsibilities include:

This project packages up a web archive (war) file capable of being deployed in any standard JEE web container. It is based upon the reference 'ssp-client' artifact provided with this implementation.

The contents of this package are purposefully minimized to the deployment configurations necessary to deploy the war file.

This project produces a jar file containing the necessary logic for sending and receiving both requests and responses, including all message handling that is pertinent to the SSP.

This jar file represents standard logic that would be implemented by any SSP wishing to leverage this implementation..

All SSP specific logic (i.e. persisting the advertiser data, retrieving publisher information, etc.) is delegated to the 'ssp-client' via the 'ssp-intf'.

This package is the contract and set of interfaces between the message handling code located in the 'ssp-core' and an SSP's specific internal representation of that data.

This package is an example implementation of the 'ssp-intf' to satisfy the following:

2. Provide a framework for other SSPs to leverage this specification more quickly by allowing the SSP to focus on the integration aspects of the specification with their own specific platform.

As a result of requirement (1) above, this package must be capable of working in concert with the 'dsp-client' described above.

This project provides a simple API that can be used to validate JSON bid requests and responses according to OpenRTB specifications. OpenRTB versions 1.0, 2.0, 2.1, and 2.2 are fully supported.
