Abstract

A method for dynamically constructing a web page is disclosed which includes receiving a uniform resource locator identifying a web page. The web page references a plurality of elements. The method also includes receiving a user identifier representing a user and evaluating each of the referenced elements based on the user identifier to identify a subset of at least one element the user is authorized to access. The method further includes determining a data conversion specification associated with the user and determining a data representation specification associated with the user. The subset of elements that the user is authorized to access is converted and presented to the user. Systems and computer-readable storage media for defining and presenting a composite web page are also disclosed.

Claims

1. A method for dynamically constructing a web page, comprising:

receiving a request for a webpage identified by a URL and defined by a plurality of GUI nodes stored in a page registry, wherein at least two of the plurality of GUI nodes each comprise an access right property defining a group of users who have access to the GUI node;

determining a security credential of a user associated with the request;

comparing, for each of the at least two of the plurality of GUI nodes, the access right property representing the group of users who have access to the GUI node to the determined security credential of the user associated with the request;

identifying, based at least in part on the comparing, a subset of the plurality of GUI nodes that the user is authorized to access;

retrieving the subset of the plurality of GUI nodes the user is authorized to access;

determining a data representation specification associated with the user, the data representation specification specifying one or more data formats appropriate for the user;

converting the subset of the plurality of GUI nodes the user is authorized to access into a script conforming to the data representation specification associated with the user;

transmitting the script to the user; and

further comprising identifying, based on the comparing, a second subset of the plurality of GUI nodes that the user is not authorized to access, wherein each GUI node of the second subset of the plurality of GUI nodes is capable of being converted into a second script conforming to the data representation specification associated with the user.

2. The method of claim 1, further comprising receiving a user identifier associated with the security credential of the user, wherein the security credential of the user is determined by retrieving the security credential using the received user identifier.

3. The method of claim 1, wherein the at least two of the plurality of GUI nodes comprises substantially all of the plurality of GUI nodes stored in the page registry.

4. The method of claim 1, wherein the subset of GUI nodes comprise disparate XML formats;

and further comprising converting the subset of GUI nodes into a common XML format using an XSL data conversion specification file.

5. The method of claim 1, wherein the data representation specification comprises an XSL file.

6. The method of claim 1, wherein the script comprises HTML, JavaScript, or Java code.

7. The method of claim 1, wherein converting the subset of the plurality of GUI nodes comprises retrieving environmental variables for the user, the environmental variables comprising one or more private XSL files for the user.

8. The method of claim 1, wherein converting the subset of the plurality of GUI nodes comprises retrieving default XSL files, the default XSL files comprising one or more XSL files shared by the user and one or more other users.

9. Logic embodied in a computer-readable medium operable, when executed by a computer processor, to perform the steps comprising:

receiving a request for a webpage identified by a URL and defined by a plurality of GUI nodes stored in a page registry, wherein at least two of the plurality of GUI nodes each comprise an access right property defining a group of users who have access to the GUI node;

determining a security credential of a user associated with the request;

comparing, for each of the at least two of the plurality of GUI nodes, the access right property representing the group of users who have access to the GUI node to the determined security credential of the user associated with the request;

identifying, based at least in part on the comparing, —

a subset of the plurality of GUI nodes that the user is authorized to access;

retrieving the subset of the plurality of GUI nodes the user is authorized to access;

determining a data representation specification associated with the user, the data representation specification specifying one or more data formats appropriate for the user;

converting the subset of the plurality of GUI nodes the user is authorized to access into a script conforming to the data representation specification associated with the user;

transmitting the script to the user; and

identifying, based on the comparing, a second subset of the plurality of GUI nodes that the user is not authorized to access, wherein each GUI node of the second subset of the plurality of GUI nodes is capable of being converted into a second script conforming to the data representation specification associated with the user.

10. The logic of claim 9, wherein the steps further comprise receiving a user identifier associated with the security credential of the user, wherein the security credential of the user is determined by retrieving the security credential using the received user identifier.

11. The logic of claim 9, wherein the at least two of the plurality of GUI nodes comprises substantially all of the plurality of GUI nodes stored in the page registry.

12. The logic of claim 9, wherein the subset of GUI nodes comprise disparate XML formats;

and wherein the steps further comprise converting the subset of GUI nodes into a common XML format using an XSL data conversion specification file.

13. The logic of claim 9, wherein the data representation specification comprises an XSL file.

14. The logic of claim 9, wherein the script comprises HTML, JavaScript, or Java code.

15. A system for dynamically constructing a webpage, comprising:

a computer-readable memory storing a GUI data manager operable, when executed, to;

receive a request for a webpage identified by a URL and defined by a plurality of GUI nodes stored in a page registry, wherein at least two of the plurality of GUI nodes each comprise an access right property defining a group of users who have access to the GUI node;

determine a security credential of a user associated with the request;

compare, for each of the at least two of the plurality of GUI nodes, the access right property representing the group of users who have access to the GUI node to the determined security credential of the user associated with the request;

identify, based at least in part on the comparisons, a subset of the plurality of GUI nodes that the user is authorized to access;

retrieve the subset of the plurality of GUI nodes the user is authorized to access;

determine a data representation specification associated with the user, the data representation specification specifying one or more data formats appropriate for the user;

convert the subset of the plurality of GUI nodes the user is authorized to access into a script conforming to the data representation specification associated with the user; and

identify, based on the comparisons, a second subset of the plurality of GUI nodes that the user is not authorized to access, wherein each GUI node of the second subset of the plurality of GUI nodes is capable of being converted into a second script conforming to the data representation specification associated with the user.

16. The system of claim 15, wherein the GUI data manager is further operable, when executed, to receive a user identifier associated with the security credential of the user, wherein the security credential of the user is determined by retrieving the security credential using the received user identifier.

17. The system of claim 15, wherein the at least two of the plurality of GUI nodes comprises substantially all of the plurality of GUI nodes stored in the page registry.

18. The system of claim 15, further comprising a web server comprising logic operable, when executed, to:

receive the request for the webpage;

transmit the request for the webpage to the GUI manager;

receive the script conforming to the data representation specification associated with the user from the GUI manager; and

transmit the script conforming to the data representation specification association to the user.

19. The system of claim 15, wherein the subset of the plurality of GUI nodes comprise disparate XML formats;

and

wherein the GUI data manager is further operable, when executed, to convert the subset of the plurality of GUI nodes into a common XML format.
