owl2vcs is a set of tools designed to facilitate version control of OWL 2 ontologies using version control systems. It contains a commandline diff tool for OWL 2 ontologies integrated with Git and Mercurial. It detects axioms additions and removals, imports' additions and removals, ontology annotations' additions and removals, prefix additions, removals, modifications, and renames, ontology IRI and version IRI changes, and ontology format changes. It supports RDF/XML, OWL/XML, OWL Functional Syntax, Manchester OWL Syntax, and Turtle. It provides a changeset serializer and parser, two formats of changes, compact (like OWL Functional Syntax) and indented (the same, but more readable, using indents instead of parentheses), and four formats of IRIs: Simple, QName, Full, and Label.
Mercurial HeadQuarter is a Web service for managing Mercurial repositories. It allows the user to define contact names, define project descriptions, set up access (read and write), set which types of archives are allowed, define encoding charsets, hide/unhide projects, set the presentation style, and redirect access and error logs to files.
AgileSCM is an application lifecycle management solution for Subversion, Git, and Mercurial. It allows you to spend more time developing and less time fighting development tools or tied up with administration. AgileSCM is a user friendly, browser-based interface which abstracts developers from the complications of SVN, Mercurial, and Git.
RhodeCode (formerly hg-app) is a Pylons framework based Mercurial repository browser/management with a built-in push/pull server and full text search. It works on http/https, has built-in permission/authentication (+ldap) features. It's similar to github or bitbucket, but it's supposed to run as a standalone hosted application and it focuses more on restricted access to repositories. It's powered by a VCS library that can handle many various version control systems.
pepper is a commandline tool for retrieving statistics and generating reports from source code repositories. It ships with several graphical and textual reports, and is easily extensible using the Lua scripting language. It includes support for multiple version control systems, including Git and Subversion.
repos-tools is a set of command-line utilities to make work on your code repositories faster and easier. It lets you push, pull, build, and do other things on your repositories all at once. The supported (D)VCSes are Git, Subersion, Bazaar, and Mercurial. For GitHub users, forking, following, watching, and dealing with issues can be done from the shell.
TurnKey Revision Control Appliance is an integrated revision control server combining the best open source version control systems: Subversion, Git, Bazaar, and Mercurial.
