Abstract

A apparatus and computer instructions for transmitting accessibility requirements. Content is received from a computer at a data processing system. The content is parsed for a selected indicator. The data processing system is queried to identify accessibility requirements in response to the selected indicator being present. The identified accessibility requirements are sent to the computer. These accessibility requirements are use by the computer to generate content for the data processing system.

a processing unit connected to the bus system, wherein the processing unit executes a set of instructions to receive, from a client, a request for a Web page, send the Web page to the client, wherein the Web page includes a specified indicator that causes the client to return accessibility requirements, wherein the specified indicator is an object type that identifies a type of server;

receive from the client an extensible markup language (XML) file containing the accessibility requirements of the client;

create an accessibility requirements object in response to receiving the XML file, wherein the accessibility requirements object contains the accessibility requirements in the XML file, and use the accessibility requirements contained in the accessibility requirements object when responding to subsequent requests for Web pages from the client.

3. A data processing system for transmitting accessibility requirements, the data processing system comprising:

requesting means for requesting a web page from a server;

receiving means for receiving the web page from the server;

parsing means for parsing content in the web page received from the server for a specified indicator, wherein the specified indicator is an object type that identifies a type of the server;

identifying means, responsive to the specified indicator being present for identifying accessibility requirements set for a client in the data processing system to form identified accessibility requirements;

generating means for generating an extensible markup language (XML) document that contains the identified accessibility requirements; and

sending means for sending the XML document that contains the identified accessibility requirements to the server, wherein the identifying means, generating means and sending means are located in a plug-in to a browser program that is activated by the specified indicator contained in the web page received from the server.

4. The data processing system of claim 3, wherein the accessibility requirements include at least one of a font type, a font size, a speech enabled interface, a visual warning for generated sounds, and a high contrast display.

5. The data processing system of claim 3, wherein the specified indicator is identified in the web page by an hypertext markup language (HTML) object type tag contained in the web page that was added to the web page by the server in response to receiving the request for the web page.

6. The data processing system of claim 3, wherein the object type is a multi-purpose internet mail extension (MIME) object type that identifies the type of the server that the web page was received from, and wherein the plug-in is chosen from a plurality of plug-ins based on the MIME object type.

7. The data processing system of claim 6, further comprising:

receiving means for receiving additional content from the server in which the additional content is generated by the server using the identified accessibility requirements.

8. The data processing system of claim 6, wherein the accessibility requirements are settings present at runtime for the client and are identified by the plug-in using an operating system application programming interface (API) to obtain accessibility settings from an operating system environment of the client.

9. A data processing system for obtaining accessibility requirements from a client, the data processing system comprising:

receiving means for receiving from the client a request for a Web page;

sending means for sending the Web page to the client, wherein the Web page includes a specified indicator that causes the client to return accessibility requirements, wherein the specified indicator is an object type that identifies a type of server;

receiving means for receiving, from the client, an extensible markup language (XML) file containing the accessibility requirements of the client;

creating means, responsive to the receiving the XML file, for creating an accessibility requirements object, wherein the accessibility requirements object contains the accessibility requirements in the XML file; and

using means for using the accessibility requirements contained in the accessibility requirements object when responding to subsequent requests for Web pages from the client.

10. The data processing system of claim 9, wherein the accessibility requirements object is maintained during a session of the client.

11. The data processing system of claim 9, wherein the server includes at least one of a servlet and an enterprise java bean that is used to respond to the subsequent requests for Web pages.

12. The data processing system of claim 9, wherein the accessibility requirements include at least one of a font type, a font size, a speech enabled interface, a visual warning for generated sounds, and a high contrast display.

13. A computer program product stored on a tangible computer readable medium for transmitting accessibility requirements, the computer program product comprising:

first instructions for requesting a web page from a server;

second instructions for receiving the web page from the server;

third instructions for parsing content in the web page received from the server for a specified indicator, wherein the specified indicator is an object type that identifies a type of the server;

fourth instructions, responsive to the specified indicator being present, for identifying accessibility requirements set for a client in a data processing system;

fifth instructions for generating an extensible markup language (XML) document that contains the identified accessibility requirements; and

sixth instructions for sending the XML document that contains the identified accessibility requirements to the server, wherein the fourth instructions, fifth instructions and sixth instructions are located in a plug-in to a browser program that is activated by receipt of the specified indicator contained in the web page received from the server.

14. The computer program product of claim 13, wherein the accessibility requirements include at least one of a font type, a font size, a speech enabled interface, a visual warning for generated sounds, and a high contrast display.

15. The computer program product of claim 13, wherein the specified indicator is identified in the web page by an hypertext markup language (HTML) object type tag contained in the web page that was added to the web page by the server in response to receiving the request for the web page.

16. The computer program product of claim 13, wherein the object type is a multi-purpose internet mail extension (MIME) object type that identifies the type of the server that the web page was received from, and wherein the plug-in is chosen from a plurality of plug-ins based on the MIME object type.
