Concept - Incorporation of Dynamic Knowledge Data into Pages at time of Download
  • The site knowledge store is designed to hold in readiness copies of assertions that may be needed for presentation within pages on that site or for use by web applications. The purpose of the download function is to ensure that any page designed to include knowledge data from the dynamic web is brought up-to-date at the time that page is downloaded to a client.
  • It is an important aim of the dynamic web that all associated processing should be done at the server. This is so that the information shall be available on any client through a regular browser and without the risks associated with the downloading of executable logic.
Presentation of Knowledge Data from the Dynamic Web
  • Information posted onto the dynamic web is visible only through pages located at a site where a copy is present. Such information is incorporated into the page immediately prior to download by selecting the appropriate version from the local site knowledge store.
  • The placement of information from the dynamic web within a page is determined by a call to server-side software. These calls are embedded in the HTML for the page and contain criteria for both:
    • selection of a subject to be described.
    • selection of the knowledge data about that subject that is to be presented in the page when it is downloaded.
Subject Selection Criteria
  • The criteria for selection of the real-world thing or concept whose description is required will be based on a condition that the local site knowledge store shall include at least one assertion for that subject with values for its meaning, context of origin and provenance that match any conditions supplied.
Knowledge Data Selection Criteria
  • The criteria for selection of assertions describing the selected subject will be based on a condition they are present in the local site knowledge store and have values for predicate, context of origin and provenance that match any conditions supplied.
