How to Contribute Fingerprints for OSS Discovery

OSS Discovery uses fingerprints to identify each open source software package. OSS Discovery needs an extensive fingerprint library in order to identify the broadest possible set of open source packages – for The Open Source Census and for enterprises and individuals who want to take inventory of their open source software. A fingerprint (also called a project rule) is made up of a set of criteria that can uniquely identify a particular open source software package. These criteria can include factors such as file names, directories, file contents and checksums. Each project rule attempts to uniquely identify an open source project with the minimal possible set of criteria.

It is important to ensure that each project rule can successfully find the target open source package, while avoiding "false positives" or conflicts with other rules. The process outlined below will help us include as many project rules as possible without creating conflicts with any previously established project rules.

The Project Rule Contribution Process

We'd love to be able to accept new project rules without any vetting, but because it's possible for a new project rule to conflict with an existing rule or be redundant with an existing rule, we have put in place a vetting process for new rule contributions. This is an outline of that process. If you haven't already done so, it would be beneficial to read the documents in the Developer Guide, especially Rule Writing for Discovery 2.

Any new rule contributions should be made using the OSS Discovery Issue Tracker. That way the submission can be fully evaluated and tracked through to inclusion with the next release of fingerprints. The Issue Tracker has an issue type of "Contribution: Project Rule". All the information below should be entered into the body of the issue form, and all contributed files attached to the Contribution: Project Rule issue.

Requirements for new project rules

Before contributing a new rule, please make sure it meets the following criteria.
