Abstract

Embodiments include a system and method of facilitating the control and management of information and actions related to the computerized creation, maintenance, processing, storage, retrieval, and use of structured electronic documents in a manner such that collections of documents which are closely related with regard to structure can be stored and maintained in conformance with a single, underlying, abstract document structure model while concurrently conforming to a user-defined document structure model.

Claims

1. A method of converting a structured document from a first schema to a second schema, the method comprising:

receiving a first structured document comprising at least one element conforming to a first schema;

identifying a declaration in the first schema and a declaration in the abstract schema that is associated with the element, wherein the declaration of the first schema is derived from the declaration in the abstract schema;

identifying a declaration in a second schema that is derived from the declaration in the abstract schema; and

generating an element of a second structured document based at least partly on the declaration in the second schema, wherein the element of the second document conforms to the second schema.

2. The method of claim 1, further comprising generating an element of an intermediate document based on the declaration of the abstract schema and the declaration of the first schema.

3. The method of claim 1, further comprising outputting the element of the second document.

4. The method of claim 1, further comprising storing the second document.

5. The method of claim 1, wherein at least one of the first and second structured documents comprise XML documents.

6. The method of claim 1, wherein the first schema comprises a concrete schema.

7. The method of claim 1, wherein the second schema comprises a concrete schema.

8. The method of claim 1, wherein the declaration of the first schema comprises at least one attribute relating at least one element of the first schema with at least one element of the abstract schema.

9. The method of claim 8, wherein the at least one attribute comprises at least one of a base attribute, a type attribute, a class attribute, or a role attribute

10. A method of generating a structured document, the method comprising:

receiving at least one element conforming to a first schema;

identifying a declaration in the first schema that is associated with the received element and which is derived from a declaration in an abstract schema;

generating an element of a structured document based at least partly on the declaration in the abstract schema, wherein the element of the structured document conforms to the first schema.

11. The method of claim 10, further comprising outputting the element of the document.

12. An XML document stored on a computer readable medium, the document comprising:

at least one element conforming to a concrete schema derived from an abstract schema,

wherein the concrete schema comprises a plurality of declarations derived from respective declarations of the abstract schema.

13. A method of searching structured documents, the method comprising:

receiving a query request comprising query terms conforming to an abstract schema;

identifying at least one declaration of at least one concrete schema, the declaration being derived from a declaration of the abstract schema;

identifying query terms conforming to the concrete schema, wherein the identifying is based on the at least one declaration of the concrete schema and the received query request;

comparing the query terms conforming to the concrete schema to at least one structured document conforming to the concrete schema; and

determining whether the at least one structured document conforming to the concrete schema matches the query request.

14. The method of claim 13, wherein receiving the query request comprises:

receiving query terms conforming to a first concrete schema;

identifying a declaration in the first concrete schema and a declaration in the abstract schema that is associated with the query terms conforming to the first concrete schema, wherein the declaration of the first concrete schema is derived from the declaration in the abstract schema; and

identifying the query terms conforming to the abstract schema based on the declaration.

15. The method of claim 13, wherein identifying the at least one declaration of the at least one concrete schema comprises identifying at least one declaration of each of a plurality of concrete schemas, the respective declaration of each of the plurality of schemas being derived from a declaration of the abstract schema;

and

wherein comparing the query terms conforming to the concrete schema to at least one structured document conforming to the concrete schema comprises comparing the query terms conforming to the concrete schema to at least one structured document conforming to one of the plurality of concrete schemas.

16. The method of claim 13, wherein comparing the query terms conforming to the concrete schema to at least one document comprises accessing a database of documents conforming to the at least one concrete schema.

17. The method of claim 16, further comprising:

receiving, over a network, a document conforming to the concrete schema; and

storing the document in the database.

18. The method of claim 13, wherein the at least one declaration comprises at least one attribute associating at least one element of the first schema with at least one element of the second schema.

19. The method of claim 18, wherein the at least one attribute comprises at least one of a base attribute, a type attribute, a class attribute, or a role attribute

20. A method of generating a standalone schema for defining structured documents, the method comprising:

receiving an abstract schema;

receiving a concrete schema derived from the abstract schema, the concrete schema comprising a plurality of element definitions; and

generating element definitions of a standalone schema based on the plurality of element definitions of the concrete schema and on declarations derived from the element definitions of the abstract schema.

21. The method of claim 20, wherein generating said element definitions of the standalone schema comprises generating elements and attributes of the ones of the element definitions based on the respective element definitions of the abstract schema.
