Microsoft’s Visual SourceSafe was not created with technical communicators in mind. It was created for engineers writing software source code. But it is successfully used by technical writers in offices around the world to control documentation.
None of the technologies mentioned so far support the production of content for purposes of producing technical documentation. Such a system is a specific type of content management that has specialized functions for technical communicators doing multi-channel publishing, yet it hasn't spun off its own specific acronym.
Microcontent refers to small, granular, and possibly representative (that can provide a summary of or a navigation to a larger set of information) bits of information, typically available on the Web. An example in the domain of journalism might be headlines and news summaries, small bits of content that can be used on a front page of the news with links to more in-depth articles. The definition has grown in scope as much as in its application.
Content producers are about to live through interesting times, to adapt the popular saying, with the dawning of The Age of Content. Industry is discovering content as a commodity; the rules are changing, and fast. What have traditionally been seen as the lowliest form of commercial content within an enterprise, technical manuals, are starting to take their place alongside the other valued corporate assets.
