Abstract

The present invention comprises a data receiver 113 that receives a request for a structural document from a terminal apparatus, a document divider 114 that divides a structural document read out from a document memory 111 in response to the data request into a page abstract 88 that shows a summary and divisional document data, and a divisional document transmitter 116 that delivers the page abstract 88 or the divisional document, configured such that the web document is division-communicated and then converted into a web document that is usable on the terminal side, and redundancy upon communication of structural documents is thus reduced through use of conversion.

Claims

1. A structural document data processing apparatus, comprising:

a document data request receiving section that receives from a terminal apparatus through a network a delivery request for a structural document;

an abstract generating section that generates an abstract showing a summary of said structural document that corresponds to said delivery request by combination of content data being elements contained in said structural document;

an abstract transmitting section that transmits the abstract to said terminal apparatus;

a content data request receiving section that receives a delivery request for content data from said terminal apparatus;

a content data extracting section that extracts from said structural document content data that corresponds to said delivery request for said content data; and

a content data transmitting section that delivers said content data extracted by said content data extracting section to said terminal apparatus.

2. The structural document delivery apparatus according to claim 1, wherein said abstract generating section correlates said content data with a unique identifier and generates said abstract by using said identifier.

3. The structural document delivery apparatus according to claim 1, wherein said structural document is a document described in a markup language for web page description.

4. The structural document delivery apparatus according to claim 1, wherein said structural document delivery apparatus acquires said structural document from a network apparatus other than said terminal apparatus connected to said network.

5. The structural document delivery apparatus according to claim 2, wherein said content data request receiving section receives said identifier as said delivery request for content data, and said content data extracting section extracts from said structural document content data that corresponds to said identifier.

11. A structural document delivery system wherein the structural document delivery apparatus of claim 1 and the terminal apparatus of claim 6 are connected by a network.

6. A terminal apparatus, comprising:

a document data request transmitting section that makes a delivery request for a structural document to a structural document delivery apparatus that delivers said structural document through a network;

an abstract receiving section that receives from said structural document delivery apparatus an abstract showing a summary of said structural document that corresponds to said delivery request from said structural document delivery apparatus by combination of content data being elements contained in said structural document;

a content data selection section that selects necessary content data with reference to said abstract;

a content data transmitting section that requests the selected content data;

a content data receiving section that receives the requested content data; and

a content data storage section that stores the received content data and said abstract in correspondence.

7. The terminal apparatus according to claim 6, wherein said content data selecting section does not choose content data that is already stored in said content data storage section as said necessary content data.

8. The terminal apparatus according to claim 6, wherein said content data storage section makes the abstract into a tree-structure, and correlates and stores said content data with the tree-structured abstract.

9. The terminal apparatus according to claim 6, wherein:

said abstract receiving section receives said abstract that is described using an identifier corresponding to said content data;

said content data selecting section selects an identifier that corresponds to said necessary content data; and

said content data request transmitting section transmits the selected identifier.

10. The terminal apparatus according to claim 6, wherein said structural document is described in a markup language for web page description.

12. A structural document delivery method, wherein:

when a delivery request for a structural document is received from a terminal apparatus through a network, generating an abstract showing a summary of said structural document that corresponds to said delivery request by combination of content data being elements contained in said structural document;

transmitting the abstract to said terminal apparatus;

when a delivery request for said content data is received from said terminal apparatus, extracting said content data corresponding to said delivery request for content data from said structural document; and

transmitting the extracted content data to said terminal apparatus.

13. A document data request method, wherein

making a delivery request for a structural document to a structural document delivery apparatus that delivers said structural document through a network;

receiving an abstract showing a summary of said structural document that corresponds to said delivery request by combination of content data being elements contained in said structural document;

selecting necessary content data with reference to the abstract; and

requesting a transmission of the selected content data.

14. A structural document delivery method, wherein

a terminal apparatus makes a delivery request for a structural document to a structural document delivery apparatus that delivers said structural document data through a network;

said structural document delivery apparatus transmits to said terminal apparatus an abstract showing a summary of said structural document that corresponds to said delivery request by combination of content data being elements contained in said structural document;

said terminal apparatus selects necessary content data with reference to the abstract sent thereto and makes a delivery request to said structural document delivery apparatus for said necessary content data; and

said structural document delivery apparatus extracts said necessary content data requested from said terminal apparatus from said structural document and delivers the extracted necessary content data to said terminal apparatus.

15. A program, whereby a computer will:

upon receiving a delivery request for a structural document from a terminal apparatus through a network, generate an abstract showing a summary of said structural document that corresponds to said delivery request by combination of content data being elements contained in said structural document;

transmit the abstract to said terminal apparatus;

upon receiving said delivery request for content data from said terminal apparatus, extract from said structural document content data that corresponds to said delivery request for content data; and

deliver the extracted content data to said terminal apparatus.

16. A program, whereby a computer will:

make a delivery request for said structural document to a structural document delivery apparatus that delivers said structural document through a network;

receive an abstract showing a summary of said structural document that corresponds to said delivery request by combination of content data being elements contained in said structural document corresponding to said delivery request;

select necessary content data with reference to the abstract; and

make a request for a transmission of the selected content data.
