Upstream Ontologist

The upstream ontologist provides a common interface for finding metadata about upstream software projects.

It will gather information from any sources available, prioritize data that it has higher confidence in as well as report the confidence for each of the bits of metadata.

The ontologist originated in Debian and the currently reported metadata fields are loosely based on DEP-12, but it is meant to be distribution-agnostic.

Provided Fields

Standard fields:

  • Name: human name of the upstream project
  • Contact: contact address of some sort of the upstream (e-mail, mailing list URL)
  • Repository: VCS URL
  • Repository-Browse: Web URL for viewing the VCS
  • Bug-Database: Bug database URL (for web viewing, generally)
  • Bug-Submit: URL to use to submit new bugs (either on the web or an e-mail address)
  • Screenshots: List of URLs with screenshots
  • Archive: Archive used - e.g. SourceForge
  • Security-Contact: e-mail or URL with instructions for reporting security issues
  • Documentation: Link to documentation on the web
  • Changelog: URL to the changelog
  • FAQ: URL to the FAQ
  • Donation: URL to a donation page
  • Funding: List of sources of funding for the project

Extensions for upstream-ontologist, not defined in DEP-12:

  • SourceForge-Project: sourceforge project name
  • Wiki: Wiki URL
  • Summary: one-line description of the project
  • Description: longer description of the project
  • License: Single line license (e.g. "GPL 2.0")
  • Copyright: List of copyright holders
  • Version: Current upstream version
  • Security-MD: URL to markdown file with security policy
  • Author: List of people who contributed to the project
  • Maintainer: The maintainer of the project
  • Homepage: homepage URL (present in debian/control in Debian packages)

Supported Data Sources

At the moment, the ontologist can read metadata from the following upstream data sources:

It will also scan README and INSTALL for possible upstream repository URLs (and will attempt to verify that those match the local repository).

In addition to local files, it can also consult external directories using their APIs:

Example Usage

The easiest way to use the upstream ontologist is by invoking the guess-upstream-metadata command in a software project:

$ guess-upstream-metadata ~/src/dulwich
Security-MD: https://github.com/dulwich/dulwich/tree/HEAD/SECURITY.md
Name: dulwich
Version: 0.20.15
Bug-Database: https://github.com/dulwich/dulwich/issues
Repository: https://www.dulwich.io/code/
Summary: Python Git Library
Bug-Submit: https://github.com/dulwich/dulwich/issues/new

Alternatively, there is a Python API as part of the upstream_ontologist Python package. There are also autocodemeta and autodoap commands that can generate output in the codemeta and DOAP formats, respectively.

Reporting bugs

When reporting bugs, please include the observed output of the guess-upstream-metadata command, the version of the upstream-ontologist package you are using, what output you were expecting, and ideally the location of the upstream source code you are using (e.g. a URL to a Git repository).

If there are additional metadata fields you would like to see supported, please let us know - either with or without a patch.

Similarly, if you have a new data source you would like to see supported, please file a bug and we can discuss how to add it.
