Benefits of technology

[0019]As mobile phones become more and more advanced, they are replacing other devices, such as personal digital assistants (“PDAs”) and notebook computers, as the next-generation PDA. Compared to other computing devices, the mobile phones offer a desirable combination of telephony functions (e.g., making and receiving phone calls), sensory

Problems solved by technology

However, this approach is not suitable for mobile environments, because mobile phones do not have reachable IP addresses.
However, modern smart phones rarely support WAP because they can interpret HTML directly.
However, when a hyperlink is broken, there is no way for a user of the hypertext system to know when it will be available again unless the user constantly polls it.
This polling process, similar to playing phone tag, is very inefficient and often leads to increased communication cost and time.
However, there is currently no mechanism to associate presence information with hyperlinks in distributed hypertext systems.
As a result, there is no efficient way for a user to keep track of the status of a resource pointed to by a hyperlink i

Example

[0138]An embodiment in accordance with the present invention for transmitting the hyperlink-presence data model may represent the properties as attributes of a hyperlink element, as shown below in Example 1:

last-update=“2011-03-10T08:30:10”last-status=“s2”monitor =“http: / / www.example.com / monitor”status-list=“s1 s2 s3”>A resource

Example 1

Representing Properties as Attributes of a Hyperlink Element

[0139]The value of each attribute in this embodiment becomes the value of the corresponding property and the href value of becomes the value of target property.

[0140]Another embodiment for transmitting the hyperlink-presence data model is to use Hyper-Text Markup Language version 5 (“HTML5”) microdata, as illustrated below in Example 3 within the “” and “” tag pair. Microdata is known as a customized name / value (or attribute / value) pair used to define a vocabulary for a specialized purpose.

Aresourceitemprop=“monitor ” / >

Example

Example 2

Representing Properties as HTML5 Microdata

[0141]Another embodiment is to use Resource Description Framework—in—attributes (“RDFa”), which is a set of XHTML attributes to augment visual data with machine-readable hints. RDFa adds a set of attribute-level extensions to XHTML for embedding rich metadata within Web documents. Example 3 below illustrates usage of RDFa to transmit the hyperlink-presence data model.

[0142]Monitor module 702 is a presence watcher module in user agent 701, whose tasks include: 1) track hyperlink access; and 2) subscribes and receives presence events from a web server 720. In some cases, web server 720 may be a gateway to a separate presence server, such as a SIP or XMPP presence server.

[0143]FIG. 8 illustrates a system and process to track hyperlink access, in accordance with an embodiment of the present invention. Message 801 conveys the click action of a user clicking a hyperlink. Message 801 results in user agent 810 sending a request 802 to a web server 820 for web server 820 to send information, including presence information, related to the hyperlink clicked on by the user. Message 803 is a response is received by user agent 810 from web server 820. This information is sent to presence watcher module 811 by way of message 805, where presence watcher module 811 tracks the information. Presence watcher module 811 c...

Abstract

Method to monitor and transfer hyperlink presence information, including: transmitting a hyperlink presence monitor request to a web server; receiving an hyperlink presence information; and rendering a hyperlink based upon the hyperlink presence information. Optionally, the hyperlink presence information is represented as one of: attributes of a hyperlink element; HTML5 microdata; RDFa data; and XHTML message data. Optionally, the hyperlink presence information includes: a last-update information to indicate when the hyperlink presence was last updated; a last-status information to indicate a latest hyperlink presence status; a monitor information to indicate a URI that points to a resource to monitor for hyperlink presence; a status-list information to indicate a list of hyperlink presence status values; and a target information to indicate the hyperlink to be monitored.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 471,507, filed on Apr. 4, 2011, the content of which is hereby incorporated by reference in its entirety.BACKGROUND[0002]1. Field of the Invention[0003]Embodiments of the present invention generally relate to hyperlink presence. More specifically, embodiments of the present invention relate to a system and method for monitoring presence information of a hyperlink, and rendering the presence information to a user.[0004]2. Description of the Related Art[0005]An architectural style that underlies the Web is REpresentational State Transfer (“REST”). A web service that is compatible with REST is said to be “RESTful.” REST provides resource management and promotes architectural choices that include: 1) Addressability—each resource can be addressed by Uniform Resource Identifier (“URI”); 2) Connectedness—resources are linked to provide navigations; 3) Uniform ...
