A semantic content management system is a concept I proposed on Dec. 17, 2010, in the essay "Imagining the Semantic Economy."
An SCMS is an extention of a traditional content management system. It adds the ability to create, edit, update and manage online directories that contain the meaning of published statements. It also gives writers and editors the ability to embed text documents with inline tags that describe the "aboutness" of its statements.
An SCMS is not a publishing system, but exhanges XML with publishing systems. It contains elements of knowledge management systems, and is positioned as an integrated XML middleware dashboard.
An SCMS would enable newsgatherers to produce new data products (data sets) from their existing workflows. It would also improve SEO for all Web journalism and make it possible for news companies to repurpose, republish and reconfigure their information with automated and semi-automated efficiency.
