Abstract

We provide exemplary systems and methods using structured markup to define objects with cache controls. Examples of structure markup include Extensible Markup Language (“XML”) and Standard Generalized Markup Language (“SGML”). A cache control structure (i.e., the XML-schema) can be added to a variety of levels or layers of granularity in the object. XML data binding, which is the process of converting XML-schema to native object code, may provide an application access to the cache controls of an object. The XML-schema may be accessed using a Uniform Resource Locator (“URL”), for example, for convenient remote access.

Claims

1. A method for defining cache controls as structured markup, comprising:

creating cache control attributes; and

representing the cache control attributes using structured markup.

2. The method of claim 1, wherein creating cache control attributes comprises creating an element for each of at least one of (a) a time between refresh, (b) a last refresh, and (c) a next refresh.

3. The method of claim 1, wherein representing the cache control attributes using structured markup comprises representing the cache control attributes using XML.

4. The method of claim 1, wherein representing the cache control attributes using structured markup comprises representing the cache control attributes using SGML.

5. The method of claim 1, further comprising:

defining objects with cache controls using the representation of the cache control attributes.

6. The method of claim 5, wherein defining objects with cache controls using the representation of the cache control attributes comprises executing CASTOR to define the objects.

7. The method of claim 5, wherein defining objects with cache controls using the representation of the cache control attributes comprises executing JAXB to define the objects.

8. The method of claim 5, wherein defining objects with cache controls using the representation of the cache control attributes comprises translating the structured markup into an object-oriented language.

9. The method of claim 8, wherein translating the structured markup into an object-oriented language comprises translating the structured markup using CASTOR.

10. The method of claim 8, wherein translating the structured markup into an object-oriented language comprises translating the structured markup into JAVA.

11. The method of claim 8, wherein translating the structured markup into an object-oriented language comprises translating the structured markup using XML data binding.

12. The method of claim 5, further comprising:

executing an application that applies the objects with cache controls for refreshing, data in the application.

13. The method of claim 12, wherein the application accesses the objects with cache controls locally.

14. The method of claim 12, wherein the application accesses the objects with cache controls remotely.

15. The method of claim 14, wherein the application accesses the objects with cache controls using a uniform resource locator (URL).

16. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform a method for defining cache controls as structured markup, the method comprising:

creating cache control attributes; and

representing the cache control attributes using structured markup.

17. A system for defining cache controls as structured markup, comprising:

means for creating cache control attributes; and

means for representing the cache control attributes using structured markup.
