caption_attribution_description: English: Generalised components of a Data as a Service (DaaS) or a Web Processing service (WPS).
context_page_description: Knowledge as a service is a computing service that delivers knowledge to users, as opposed to data or information. In relation to KaaS, knowledge is data + context, that is, data with the addition of information that enables users' understanding of the data - definitions and semantics - its relation to the users' situation or the situation in which the data was produced or that which it aims to provide information about.
  Knowledge as a service is one of the series of "... as a Service" computing services.
context_section_description: The following image describes Data as a service and processing services, such as the Web Processing Service's components. 
  The following diagram indicates that a KaaS is a DaaS or WPS "+", that is, a DaaS or WPS plus some additional element that realises the "knowledge" offering of the service.
  The following diagrams provide several potential modes of KaaS operation in which different sources of the information/calculation that separates a KaaS from a DaaS or a WPS are utilised. A real-world KaaS might indeed utilise multiple.
