The web content lifecycle is the multi-disciplinary and often complex process that web content undergoes as it is managed through various publishing stages. Authors describe multiple "stages" (or "phases") in the web content lifecycle, along with a set of capabilities such as records management, digital asset management, collaboration, and version control that may be supported by various technologies and processes. One recognized technology for managing the web content lifecycle is a web content management system. Concepts often considered in the web content lifecycle include project management, information management, information architecture, and, more recently, content strategy, website governance, and semantic publishing. Various authors have proposed different "stages" or "phases" in the content lifecycle. Broadly speaking, the stages include content creation/development, revision, distribution, and archiving. The lifecycle processes, actions, content status, and content management roles may differ from model to model based on organizational strategies, needs, requirements, and capabilities. In 2003, McKeever described "two iterative phases": "the collection of content, and the delivery or publishing of that content on the Web." She also explains a Web Content Management (WCM) "four layer hierarchy"ócontent, activity, outlet, and audienceóintended to illustrate the breadth of WCM. Bob Boiko's Content Management Bible emphasizes three major parts: collect (creation and editing is much more than simply collecting), manage (workflows, approvals, versioning, repository, etc.), and publish. These concepts are graphically displayed in a Content Management Possibilities poster developed by Boiko. The poster details such content management concepts as metadata, syndication, workflows, repositories, and databases. Gerry McGovern also sees three "processes," designating them creation, editing, and publishing. JoAnn Hackos' Content Management for Dynamic Web Delivery argues for four "components": authoring, repository, assembly/linking, and publishing.
