Apache Subversion
advanced version control system
Apache Subversion (often abbreviated SVN, after its command name svn) is a version control system. The software is distributed as open source software, under the Apache License. Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation. Subversion is generally used to aid in the software lifecycle process, including code commits, binary releases, fault reporting and retraction, patch releases, and developer updates (including documentation). Subversion is an important tool in software development lifecycle tasks such as software versioning. It provides an easy command line or application-based way to commit, branch, revert, and release all sorts of files (not only source code), though it is most used by the software development community. Unlike Git, which it predates, SVN repositories are more often maintained on privately maintained servers. Subversion's goal is to be a mostly compatible successor to the previously more widely used Concurrent Versions System (CVS).
The open source community has used Subversion widely: for example, in projects such as Apache Software Foundation, FreeBSD, SourceForge, and from 2006 to 2019, GCC. CodePlex was previously a common host for Subversion repositories.
Subversion was created by CollabNet Inc., and first released in 2000.
“Apache Subversion” enters the record as advanced version control system. Crown Archives preserves that source wording while asking what Apache, Subversion and advanced can confirm, complicate or overturn.
Why this record matters
“Apache Subversion” is worth following because a concise public description often conceals a longer documentary argument. Here, Apache, Subversion and advanced provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q46794. VIAF identifies the subject as 177165689. The Library of Congress control number is n2006066336. 3 of 6 selected statements include explicit references; 2 carry qualifiers and 1 use preferred rank. The first chronological checks are 2006, 2019 and 2000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
