Concepts
- Files are created and associated with Components.
- Components form a directed graph where each Component can have several parents. Components are a logical grouping mechanism allowing Files to be grouped together without regard to their physical pathnames (unlike directories or folders which lie on the path).
- Permissions can be given at the Component level, allowing for distributed administration. The permission to give other permissions can be granted.
- A Release was a set of files with a common root. Releases could share files with other releases. The sharing could be defined to follow the latest version (sometimes called "tip") or a specific version within the release. This was called "linking".
- A Level is a snapshot of all files. Similar to a "tag" in other source control systems - but with a twist. If the Release is in "binding mode" (most commonly used), the Levels contain only the files referenced by the LevelMembers (Defects and Features). As a result, a Level only contains changes (file versions) that are approved and not just the latest file versions in the repository.

Famous quotes containing the word concepts:
“Institutional psychiatry is a continuation of the Inquisition. All that has really changed is the vocabulary and the social style. The vocabulary conforms to the intellectual expectations of our age: it is a pseudo-medical jargon that parodies the concepts of science. The social style conforms to the political expectations of our age: it is a pseudo-liberal social movement that parodies the ideals of freedom and rationality.”
—Thomas Szasz (b. 1920)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
