Abstract

A production system and method for producing a VIPDL output stream from a dynamic document and a recipients list including a data iterator for iterating through the recipients list one record at a time and computing values for each dynamic object in the dynamic document for the record, a document instantiator for creating an instance document for the record, an output generator operating in tandem with the document instantiator for generating code specifying the rendering of the document instance, and a merge component for generating the VIPDL output stream from output of the output generator.

Claims

1. A method for producing a VIPDL output stream from a dynamic document and a recipients list comprising the steps of:

selecting a next record from said recipients list;

generating a document instance from said dynamic document for said selected record from said recipients list;

generating a rendering specifications section for said generated document instance;

concatenating said rendering specifications section into said VIPDL output stream; and

repeating said steps of selecting, said step of generating a document instance, said step of generating a rendering specifications section, and said step of concatenating until said recipients list has been exhausted.

2. The method according to claim 1 further comprising the steps of generating entries in a definition dictionary corresponding to reusable objects in said dynamic document and generating elements definition section from the information in said definitions dictionary and pre-pending said elements definition section at the head of said VIPDL output stream, wherein said step of selecting a next record from said recipients list, said step of generating a document instance;

said step of generating entries in a definition dictionary, said step of generating a rendering specifications section, said step of concatenating, said step of repeating, and said step of generating elements definition section are performed by pipeline processing.

3. A method according to claim 1, wherein said step of generating a document instance comprises the steps of:

collapsing all the queries for the set of said dynamic content objects into one query; and

computing said one query.

4. A method according to claim 1, wherein said step of generating a document instance comprises the steps of:

caching views generated by queries; and

reusing said cached views.

5. A method according to claim 1, wherein said VIPDL output stream is defined in an object-oriented specification language.

6. A method according to claim 5, wherein said object-oriented specification language is VPS.

7. A method according to claim 5, wherein said object-oriented specification language is PPML.

8. A method according to claim 1, wherein said VIPDL output stream is defined in HTML.

9. A method for producing a VIPDL output stream from a dynamic document and a recipients list comprising the steps of:

receiving a recipient list;

dividing said recipients list into a plurality of distinct parts;

performing parallel processing to merge said dynamic documents independently with each of said parts; and

merging a plurality of definition dictionaries and a plurality of rendering specifications sections created in said step of performing into one VIPDL output stream corresponding to said entire recipients list, wherein said step of performing is performed by pipeline processing.

10. A method according to claim 9, wherein said step of performing further comprises the step of:

using a gossiping mechanism to reduce redundancy in said plurality of definition dictionaries.

11. A method according to claim 9, wherein said VIPDL output stream is defined in an object-oriented specification language.

12. A method according to claim 11, wherein said object-oriented specification language is VPS.

13. A method according to claim 11, wherein said object-oriented specification language is PPML.

14. A method according to claim 9, wherein said VIPDL output stream is defined in HTML.

15. A method for producing a VIPDL output stream from a dynamic document and a recipients list comprising the steps of:

receiving a recipient list;

dividing said recipients list into a plurality of distinct parts;

performing parallel processing to merge said dynamic documents independently with each of said parts, wherein said step of performing further comprises the steps of;

selecting a next record from said recipients list;

generating a document instance from said dynamic document for said selected record from said recipients list;

generating entries in a definition dictionary corresponding to dynamic content objects in said dynamic document;

generating a rendering specifications section for said generated document instance;

concatenating said rendering specifications section into said VIPDL output stream;

repeating said step of selecting, said step of generating a document instance;

said step of generating entries in a definition dictionary, said step of generating a rendering specifications section, said step of concatenating until said recipients list has been exhausted; and

generating an elements definition section from the information in said definitions dictionary and pre-pending said elements definition section at the head of said VIPDL output stream.

16. A method according to claim 15, wherein said step of generating a document instance comprises the steps of:

collapsing all the queries for the set of said dynamic content objects into one query; and

computing said one query minimizing joins.

17. A method according to claim 15, wherein said step of generating a document instance also comprises the steps of:

collapsing all the queries for the set of said dynamic content objects into one query; and

computing said one query minimizing re-selections.

18. A method according to claim 15, wherein said step of generating a document instance also comprises the steps of:

caching views generated by queries; and

reusing said cached views.
