Open source
practice of publishing digital resources publicly alongside their source code or source files
Open source is the practice of publishing digital resources publicly alongside their source code or source files, enabling use, study, modification, and redistribution. It is historically and commonly associated with open-source software, software released with its source code. The concept has also been applied beyond software to other digital resources made available alongside their source files or design documents, such as open-source hardware, open-source educational resources or open-source fonts. The rights to reuse this type of digital resources are guaranteed through a specific legal framework, whether with open licenses or public domain dedication. The development of open source resources can be based on open collaboration, a decentralized and peer-to-peer model of production.
Open source resources are a shared component across openness movements — such as open-source software, open hardware, open education or open music — with each domain having distinct types of source files and distribution formats to manage. While the sharing of source code is an established practice with software, open resources in other fields may not systematically provide their source files, restricting the ability to modify these digital resources despite the rights granted to users.
The term open source can also refer to publicly available sources of information, notably in intelligence field with open-source intelligence (OSINT). By analogy to such practices of public access and collaboration, the notion is also used more loosely across many domains.
Source files
Source files are the files containing the original, editable version of a digital resource from which a final format can be created – suitable for distribution and end use.
“Open source” enters the record as practice of publishing digital resources publicly alongside their source code or source files. Crown Archives preserves that source wording while asking what source, practice and publishing can confirm, complicate or overturn.
Why this record matters
“Open source” is worth following because a concise public description often conceals a longer documentary argument. Here, source, practice and publishing provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q39162. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
