Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to content management in digital processing systems, and more specifically to a method and apparatus for minimizing problems in accessing referred content. [0003] 2. Related Art [0004] There are often scenarios in which content ("referred content") from one source is referred to in the content of another source. For example, when a user accesses a web page, the web page may be defined to contain content of several files, and the web page delivered to the user contains the contents of all such files. The files thus accessed (and containing the referred content) are termed to as referred documents and the web page is termed as the referrer document. [0005] While the referred content in the above example is provided as integral to the referrer document (for example, due to the definition of the web page), there are other scenarios in which the referred content is delivered external to the referrer document. As an illustration, many web pages often contain hyperlinks with an associated Uniform Resource Locator (URL), and a user selects the hyperlink to access the content of the (referred) document corresponding to the URL. [0006] Users are known to experience problems in accessing referred content, typically because of changes to the document identifier of the referred documents or deletion of the referred documents themselves. A document identifier refers to a name/string (often including directory structure where the document is located), which is used to uniquely identify the document interfacing with the system software (e.g., operating system) executing on a system from which the document is accessible. [0007] In such situations, user accessing content are displayed messages such as `file not found` or a portion of the display containing blank. It is generally desirable that such access problems be avoided. BRIEF DESCRIPTION OF THE DRAWINGS [0008] The present invention will be described with reference to the accompanying drawings briefly described below. [0009] FIG. 1 is a block diagram of an example environment in which various aspects of the present invention can be implemented. [0010] FIG. 2 is a flow-chart illustrating the manner in which problems in accessing referred documents can be minimized according to an aspect of the present invention. [0011] FIG. 3 contains a table illustrating an example data structure used for maintaining a list of referring documents associated with each referred document according to an aspect of the present invention. [0012] FIG. 4A is a flow-chart illustrating the manner in which a web server and a content server together may minimize errors while accessing contents corresponding to referred documents. [0013] FIG. 4B is a flow-chart illustrating the manner in which a web server and a content server together process a request for providing contents of a referred document according to an aspect of the present invention. [0014] FIG. 5A depicts a data structure used for maintaining mapping of a Universal Resource Locator (URL) to a corresponding virtual link in an embodiment of the present invention. [0015] FIG. 5B depicts a data structure used for maintaining the mapping of a virtual link to corresponding document identifier in an embodiment of the present invention. [0016] FIG. 5C depicts a data structure illustrating the changes to be made in the data structure of FIG. 5B when a document identifier changes, in an embodiment of the present invention. [0017] FIG. 6 is a block diagram illustrating an example embodiment in which various aspects of the present invention are operative when software instructions are executed. [0018] In the drawings, like reference numbers generally indicate identical, functionally similar, and/or structurally similar elements. The drawing in which an element first appears is indicated by the leftmost digit(s) in the corresponding reference number. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0019] 1. Overview [0020] According to an aspect of the present invention, data indicating the referrer documents corresponding to each referred document is maintained. Thus, when there is a change of the document identifier (either moved to a new location, deleted or renamed) of a referred document, the corresponding referrer documents which may require changes are easily identified. In one embodiment described below, the administrator corresponding to each of such identified referrer documents is notified of the change to the document identifier of the referred document. [0021] According to another aspect of the present invention, a server ("web server"), processing requests for web pages identified by corresponding Uniform Resource Locators (URLs), maintains a map of the URL to a logical link. A content server providing the document corresponding to the URL maintains a mapping from the logical link to the document identifier.
