Abstract

A data management system for generating customized versions of data documents. Initially the document is stored as in the form of raw data, which is subsequently parsed into an internal representation of the document. In one embodiment, raw data is stored in XML form and is parsed by an XML parser. Upon the initial request for a customized version of the document, a sequence of transforms is applied to the internal representation and to subsequently transformed documents in order to create hierarchical, customized document levels. In one embodiment, transforms are implemented as either XSL stylesheets, although Java classes may also be employed. The document versions are written to cache, and subsequent requests for existing versions of the document are referred to cache. In the event that any document dependencies change, a cached version will be denoted invalid, and subsequent requests will result in the re-generation of a customized version.

Claims62

Dependent claims

A method of generating customized versions of a document using a computer system, the method comprising:

storing the document in raw form;
parsing the document to create an internal representation of the document;
receiving a request to generate a second-level document;
decomposing the document to create the second-level document, wherein decomposing the document comprises:
applying a first first-level transform to the internal representation of the document to create a first first-level document;
and
in response to the request to generate the second-level document, applying a second-level transform to the first first-level document to create the second-level document;
decomposing the document to create a second first-level document, wherein decomposing the document to create the second first-level document comprises:
applying a second first-level transform to the internal representation of the document to create a second first-level document;
tracking changes to at least one of:
(i) the raw form of the document, (ii) the first first-level transform, (iii) the second level transform, and (iv) the second first-level transform;
regenerating the document created using any of (i)-(iv) whose changes are tracked if a change occurs in any of (i)-(iv) whose changes are tracked;
and
designating a previously stored version of the regenerated document invalid;
wherein the first first-level document and the second first-level document are different.

12 more elements

A computer readable medium having code stored therein to cause a data processing system to generate a data document according to a process comprising:

storing a raw form of the document;
parsing the document to create an internal representation of the document;
and
receiving a request from a client computer system coupled to the data processing system to generate a second-level document into a particular form;
decomposing the document into the form requested by the client system, wherein decomposing the document comprises:
applying a first first-level transform to the internal representation of the document to create a first first-level document;
and
in response to the request to generate the second-level document, applying a second-level transform to the first first-level document to create the second-level document;
decomposing the document to create a second first-level document, wherein decomposing the document to create the second first-level document comprises:
applying a second first-level transform to the internal representation of the document to create a second first-level document;
tracking changes to at least one of:
(i) the raw form of the document, (ii) the first first-level transform, (iii) the second level transform, and (iv) the second first-level transform;
regenerating the document created using any of (i)-(iv) whose changes are tracked if a change occurs in any of (i)-(iv) whose changes are tracked;
and
designating a previously stored version of the regenerated document invalid;
wherein the first first-level document and the second first-level document are different.

13 more elements

A system comprising:

a processor;
and
a memory, coupled to the processor, having code stored therein to cause the system to generate a data document, wherein the code is executable by the processor for:
storing a raw form of the document;
parsing the document to create an internal representation of the document;
and
receiving a request from a client computer system coupled to the data processing system to generate a second-level document into a particular form;
decomposing the document into the form requested by the client system, wherein decomposing the document comprises:
applying a first first-level transform to the internal representation of the document to create a first first-level document;
and
in response to the request to generate the second-level document, applying a second-level transform to the first first-level document to create the second-level document;
decomposing the document to create a second first-level document, wherein decomposing the document to create the second first-level document comprises:
applying a second first-level transform to the internal representation of the document to create a second first-level document;
tracking changes to at least one of:
(i) the raw form of the document, (ii) the first first-level transform, (iii) the second level transform, and (iv) the second first-level transform;
regenerating the document created using any of (i)-(iv) whose changes are tracked if a change occurs in any of (i)-(iv) whose changes are tracked;
and
designating a previously stored version of the regenerated document invalid;
wherein the first first-level document and the second first-level document are different.
