Data delivery system and sending station therefor
First Claim
1. A data delivery system for delivering data stored in a sending station to at least one receiving station, comprising:
- distribution tables, disposed in the sending station, each defining parameters regarding where and how to deliver engineering documents of a particular product category, the parameters including destinations of each different type of documents and data formats supported in each of the destinations;
attribute identification means, disposed in the sending station, for identifying attributes of data to be distributed, the attributes including document types;
destination determination means, disposed in the sending station, for determining destinations of the data, according to the document type identified by said attribute identification means, by consulting one of said distribution tables relevant to a specified product category;
transmission means, disposed in the sending station, for sending the data to the destinations determined by said destination determination means;
reception means, disposed in each receiving station, for receiving the data sent from said transmission means;
reproduction means, disposed in each receiving station, for restoring the data received by said reception means to original form thereof;
data conversion means, disposed in the sending station, for converting the data into image data or plotter data;
distribution information embedding means for adding distribution-related information pertaining to the data distribution to the image data or plotter data produced by said data conversion means, andwherein said transmission means sends the data converted by said data conversion means.

Abstract
A data delivery system which delivers created data to all the parties that need it. Documents such as engineering drawings are stored as bulk data files in a bulk data database. Metadata files containing attribute information of bulk data are stored in a metadata database. When the date and time of a data distribution session is given to a date/time setting unit, an attribute identification unit makes access to a relevant metadata file to identify the attributes of the bulk data to be transmitted. Based on this result, a destination determination unit determines the destinations of each bulk data file. A format identification unit then identifies which data formats the receiving stations can handle. If necessary, the data format is changed by a format converter, so as to meet the requirements of each destination. Summary data briefly describes what kinds of bulk data files are to be distributed. A summary data transmitter compiles such summary data and sends it to the receiving stations. Each receiving station now returns a downloading request, and in response to this, a transmitter sends out the requested bulk data files, which meets the destination'"'"'s format guideline. A receiver in the receiving station accepts those bulk data files and a reproduction unit restores the received data to its original form.

9. A computer-readable medium containing a program which delivers data stored in a sending station to at least one receiving station, the computer program being designed to run on a computer in order to cause the computer to execute operations, comprising:
-
providing distribution tables, each defining parameters regarding where and how to deliver engineering documents of a particular product category, the parameters including destinations of each different type of documents and data formats supported in each of the destinations; identifying attributes of data to be distributed, the attributes including document types; determining destinations of the data according to the attributes identified; and sending the data to the destinations determined; wherein the data is converted into image data or plotter data and distribution-related information pertaining to distribution of the data is added to the image data or plotter data for sending the data.
