Software Maintainer Development status Repository model Concurrency model License Platforms supported Cost
- Software: The name of the application that is described.
- Maintainer: The company or group that is currently taking responsibility for the software's maintenance or development
- Development Status: The current status of the software project
- Repository model: describes the relationship between various copies of the source code repository. In a client–server model, users access a master repository via a client; typically, their local machines hold only a working copy of a project tree. Changes in one working copy must be committed to the master repository before they are propagated to other users. In a distributed model, repositories act as peers, and users typically have a local repository with version history available, in addition to their working copies.
- Concurrency model: describes how changes to the working copy are managed to prevent simultaneous edits from causing nonsensical data in the repository. In a lock model, changes are disallowed until the user requests and receives an exclusive lock on the file from the master repository. In a merge model, users may freely edit files, but are informed of possible conflicts upon checking their changes into the repository, whereupon the version control system may merge changes on both sides, or let the user decide when conflicts arise. Note that distributed version control almost always implies a merge concurrency model.
- License: The license model under which the software is licensed. These can be both free and paid licenses
- Platforms Supported: The operating systems that the software application currently supports.
- Cost: The price of the software application

- Software: The name of the application that is described.
- Programming language: The coding language in which the application is being developed
- History model: describes the form in which changes are stored in the repository. For example, when a change is committed, a system could store a copy of the tree before and after the change (snapshot), or it might instead store a copy of the tree before the change and a changeset representing the changes.
- Scope of change: Describes whether changes are recorded for individual files or for entire directory trees.
- Revision IDs: are used internally to identify specific versions of files in the repository. Systems may use pseudorandom identifiers, content hashes of revisions, or filenames with sequential version numbers (namespace). With Integrated Difference, revisions are based on the Changesets themselves, which can describe changes to more than one file.
- Network protocols: lists the protocols used for synchronization of changes.
- Source code size: Gives the size of the source code in megabytes.

- Software: The name of the application that is described.
- Atomic commits: refers to a guarantee that all changes made are merged, or that no change at all will be made.
- File renames: describes whether a system allows files to be renamed while retaining their version history.
- Merge file renames: describes whether a system can merge changes made to a file on one branch into the same file that has been renamed on another branch (or vice versa). If the same file has been renamed on both branches then there is a rename conflict that the user must resolve.
- Symbolic links: describes whether a system allows revision control of symbolic links as with regular files. Versioning symbolic links is considered by some people a feature and some people a security breach (e.g., a symbolic link to /etc/passwd). Symbolic links are only supported on select platforms, depending on the software.
- Pre/post event hooks: indicates the capability to trigger commands before or after an action, such as a commit, takes place.
- Signed revisions: refers to integrated digital signing of revisions, in a format such as OpenPGP.
- Merge tracking: describes whether a system remembers what changes have been merged between which branches and only merges the changes that are missing when merging one branch into another.
- End of line conversions: describes whether a system can adapt the end of line characters for text files such that they match the end of line style for the operating system under which it is used. The granularity of control varies. Subversion, for example, can be configured to handle EOLs differently according to the file type, whereas Perforce converts all text files according a single, per-client setting.
- Tags: indicates if meaningful names can be given to specific revisions, regardless of whether these names are called tags or labels.
- International Support: indicates if the software has support for multiple language environments and operating system
- Unicode filename support: indicates if the software has support for interoperations under file systems using different character encodings.
- Supports large repos: Can the system handle repositories of around a gigabyte or larger effectively?

- keyword expansion: Supports automatic expansion of keywords such as file revision number.
- interactive commits: Interactive commits allow the user to cherrypick the patch-hunks that become part of a commit (leaving unselected changes as changes in the working copy), instead of having only a file-level granularity. See darcs record.
- external references: embedding of foreign repositories in the source tree
- partial checkout/clone: Ability to check out or clone only a specified subdirectory from a repository.
- permissions: Tracks file permission bits in the revision history.
- timestamp preservation: Overwrites the last modified filesystem attribute with the commit time upon checkout.
- custom automatic merge tool: Automatic merging can be attempted by any tool of the user's choice (hopefully configurable on a per-file basis)
- supported formats: either read/write support or read-only (conversion, potentially repeated)
- shared build cache of derived objects: the ability to wink-in derived-objects that were built by other confederated clients that share exactly the same dependencies instead of rebulidng them locally

- ^ Bazaar is a Distributed version control system but it can also be used in a centralized manner using lock step development and checkouts.
- ^ Computer Associates, http://www.ca.com/ .
- ^ In ClearCase, a trigger may be set to allow for the lock model, and this is done at many sites. However, ClearCase development usually takes place on private branches where each developer is given their own branch, so the lock vs. merge concurrency model doesn't matter as much. Code is merged back to the main branch once the developer is ready to deliver their code to the project.

- ^ Bazaar's critical modules are written in Pyrex. They are automatically translated to pure C; except for the patience sorting module, used in merge resolution, which is written directly in the C language.
- ^ A Bazaar bundle is a summary diff, with sufficient extra information to preserve history.

- ^ Mercurial revision numbers are local to a repository; they can differ from repository to repository depending on in which order merges are performed.
- ^ A Monotone's revisions represent changesets and its manifests represent snapshots, each revision is linked to some manifest. But manifests are legacy constructs, they aren't kept in the database anymore and reconstructed on the fly if needed. The real work now happen in rosters which are hybrid snapshot/changeset structures.
- ^ They can be automatically generated and manually verified, but verification is not automatic; http://bazaar-vcs.org/BzrGpgSigning
- ^ EOL conversions are supported since bzr 1.14
- ^ Atomic commit can be enabled for individual checkin's ClearCase 7.1.1 release notes.
- ^ Support Policy for National Languages and ClearCase from IBM Support
- ^ darcs' patches each bear a unique identifier, impossible to merge twice the same patch in a repository (without destructively modifying history using "unsafe" commands).
- ^ Git does not explicitly track renames, because by design it does not track individual files. Renames and split of source files are detected after the fact, if the file content does not change dramatically.
- ^ Git does not sign commits, only tags. See the -s option in git-tag(1) Manual page
- ^ Git itself is not internationalized, just git-gui and gitk (both are shipped with git).
- ^ libgit2 and msysgit is starting storage the internal file name as UTF8, so the answer is near to YES
- ^ Integrity enabled change packages provide complete workflow and 21 CFR Part 11 compliant digital signatures against the item controlling the change package.
- ^ 2009 SP5 added a feature to merge child development paths.
- ^ Its possible to embed the action in a shell or Ant script.
- ^ A merged is tracked by its workspace origin.
- ^ Mercurial is in the process of being translated to at least dutch and chinese
- ^ Mercurial is encoding agnostic and hence can work with all file names without problems. Indeed, it's can not checkout those files properly, so the answer is no.

- ^ StarTeam supports atomic commits as of version 2006
- ^ Subversion can move a file and conserve its history, if and only if the target of the move is in the same Subversion repository as the source. Cross-repository moves require third-party tools such as svk. Also, a rename operation is actually a copy-with-history-and-delete sequence.
- ^ New to SVN 1.5 (http://subversion.apache.org/docs/release-notes/1.5.html#merge-tracking). A separate tool "svnmerge" (http://www.dellroad.org/svnmerge/) provides merge tracking for older versions.
- ^ In Subversion, tags are a special case of the more generic "cheap copy" concept of Subversion. Per convention, a tag is a copy into a directory named "tags". Because of this, even tags are versioned. See http://svnbook.red-bean.com/nightly/en/svn.branchmerge.tags.html for more information. The reason for partial support in the table is because Subversion's emulation of tags in this manner does not meet the requirement that the tag name can be used in place of any revision identifier wherever the user may be required to enter one. This column would be meaningless if the definition were to be loosened enough to encompass Subversion's approach as every version control system supports branching and would therefore support tags as well.
