Introduction

Open source software has eaten the world, but organizations are still struggling with effective compliance. Open source software is heterogenous and re-used, which, while positive for software development, creates a challenge for compliance. Compliance requires multiple tools and these should be ideally combined into a workflow that supports a number of business and developer requirements. One of the requirements is ease of use in a modern development environment where code development cycles are getting ever shorter and new development results are pushed to operations ever faster. For this to work, open source compliance tools likely need to integrate with development tooling.

In the following report some of these tools are listed with information of their main license, website and a summary of their features, based on accounts by the projects. The report has been crafted to map out the wide range of open source tools that one might use to help keep their open source software compliant. However, this report, ever so comprehensive, is not exhaustive. The report includes FOSS tools as well as a few commercial tools. It also has a section for Open Source Initiatives and Development Environments, as these are also important on a way towards automated open compliance with open tooling and open data.

This report will be complemented based on an ecosystem survey and on practical testing of the most popular open source tools.

This report is part of the first work package in the Double Open project. See doubleopen.org for more details.


Open Compliance Initiatives

ClearlyDefined

Website

ClearlyDefined.io

ClearlyDefined on GitHub

Summary

ClearlyDefined is a community / contributor powered project in which the goals are:

  1. Raise awareness about lack of clarity around licenses and security vulnerabilities within FOSS project teams
  2. Automatically harvest data from projects
  3. Make it easy for anyone to contribute missing information
  4. Crowd-source the curation of these contributions
  5. Feed curated contributions back to the original projects

ClearlyDefined provides a mechanism for harvesting available data using tools such as ScanCode and FOSSology, and facilitates crowd-sourcing the curation of that information when ambiguities or gaps arise. The ultimate goal of harvesting and curation is to contribute any new-found clarity (e.g., new licenses found) to the upstream projects so they can include the updates in their next release. The project focuses now on clarifying individual project's license, source code location and copyright holders, but do see security, accessibility, and internationalization being important parts of the ClearlyDefined ecosystem.

Eclipse Oscano

Website

Eclipse Oscano

Summary

The mission of the Oscano project is to solve the problem of scaling SCA to modern needs with Open Source approach. The Eclipse Oscano project provides a complete software composition analysis solution, focused on compliance and security, that can be installed on cloud, local server, or workstation environment. To achieve this, existing OSS components will be reviewed by the project team for possible integration into the Oscano stack and capabilities not existing will be built and integrated. Main use cases of Oscano include Open Source license compliance management, open source inventory management, vulnerability remediation automation and software analysis reporting.

The solution is designed to meet the challenge of massively increasing scale and continuous nature of build and releasing of modern software systems. It addresses the scaling problem through four principal means:

  1. Continuous and fully automated operation cycle from new code commit to analysis, scan and action
  2. Maximum engagement of developers in the software analysis and management use cases for direct and early troubleshooting
  3. Risk-based smart analysis of compliance and vulnerability issues
  4. Maximum re-use of pre-scanned open source software data.

Automated Compliance Tooling ACT

Website

ACT

Summary

ACT is a Linux Foundation project. The goal is to consolidate investment in, and increase interoperability and usability of, open source compliance tooling, which helps organizations manage compliance obligations. ACT also welcomes two new projects to be hosted at The Linux Foundation as part of the initiative, in addition to two existing Linux Foundation projects that will become part of the new project. The new projects are complementary to existing Linux Foundation compliance projects such as OpenChain, which identifies key recommended processes to make open source license compliance simpler and more consistent, and the Open Compliance Program, which educates and helps developers and companies understand their license requirements and how to build efficient, frictionless and often automated processes to support compliance.

The four projects that will be part of ACT are:

  • FOSSology
  • QMSTR
  • SPDX Tools
  • Tern

OpenChain

Website

OpenChain

Summary

OpenChain is a project hosted by the Linux Foundation. It answers a question: "How do I trust my open source supply chain"? It provides a framework for shared, compliant use of FOSS. Conforming companies create an environment that supports use of FOSS internally and sharing of FOSS with partners. The OpenChain Specification defines a core set of requirements every quality compliance program must satisfy. OpenChain Conformance allows organizations to display their adherence to these requirements. The OpenChain Curriculum supports this process by providing extensive reference material for effective open source training and management. The result is that open source license compliance becomes more predictable, understandable and efficient for all participants in the software supply chain.

Sharing-creates-value

Website

Sharing-creates-value

Summary

This is GitHub repository hosted by Siemens. Sharing creates value strives for the goal to lower the required effort in license compliance work for all who want to make use of OSS in a license compliant way. To achieve this Sharing creates value will develop, share and improve the artifacts needed to fulfill the requirements of the different Free and Open Source Software licenses by applying the Open Source Software development principles.

Another objective of Sharing creates value is a very close collaboration with the OSS community in order to fix detected "bugs" in licensing as well as introducing the information needed for license compliance activities in the Open Source projects, i.e. provide our analysis work to the OSS projects.

Last but not least Sharing creates value support tools which will help automate and reduce effort in component management, license identification and OSS license compliance activities.

Sharing creates value wants to be the platform, which provides all information and artifacts for OSS license compliance.
