The transmission / reception unit 6 has a function of receiving a URL from the client 5 using a predetermined protocol and returning a document file specified by the URL to the client 5 using a predetermined protocol.
[0019]
The revision number obtaining unit 7 obtains the folder name and the file name of the document file specified by the URL, further determines whether the received URL specifies a revision number, and if specified, converts the revision number to the received URL. It has a function of acquiring and transferring it to the file search unit 8.
[0020]
The file search unit 8 searches the content database 2 using the folder name, the file name, and the revision number extracted by the revision number acquisition unit 7, and stores information provided to the client 5 as a document file specified by the client 5. It has a function of extracting a file name of a recorded document file (hereinafter, referred to as “original document file”) and transferring the extracted file name to the document creation unit 9. If no revision number has been received from the revision number acquisition unit 7, the file name of the original document file having the latest update date is extracted.
[0021]
The document creation unit 9 searches the document database 3 using the file name of the original document file acquired by the file search unit 8, acquires the original document file corresponding to the file name, and transfers the document file to the transmission / reception unit 6. Have.
[0022]
As shown in FIG. 3, the content database 2 is a database having items of a folder, a document name, a revision number, a file name, and an update date. In the item of the folder, the folder of the document file designated by the client 5 is recorded, and in the item of the document name, the file name of the document file accessible by the client 5 is recorded. In the item of the revision number, the revision number of the document file is recorded, and in the item of the file name, the file name of the original document file indicated by the revision number is recorded. Each time the original document file is revised, a new revision number and file name are given. In the item of the update date, the date when the information was revised is recorded.
[0023]
The document database 3 is a database that stores original document files that can be presented to the client 5.
[0024]
Next, a processing procedure of the information management device 1 when a URL is received from the client 5 will be described with reference to FIGS.
[0025]
First, when a URL is received from the client 5 (step S01), the revision number obtaining unit 7 obtains a folder name and a file name from the URL (step S02). For example, when the URL “http://www.toshiba.co.jp/unitA/part1.html rev1” is received from the client 5, the revision number acquisition unit 7 removes the host name from the URL, and deletes the folder name “unitA”, The file name “part1.html” is extracted.
[0026]
Next, the revision number acquisition unit 7 determines whether the received URL has a designation of a revision number (step S03). If the URL includes a revision number, the revision number is obtained (step S04). In the case of the above URL example, the revision number “rev1” is acquired. The revision number acquisition unit 7 transfers the acquired folder name, file name, and revision number to the file search unit 8.
[0027]
Next, when no revision number is specified, the file search unit 8 refers to the document name, the file name, and the update date in the content database 2 to obtain the file name of the original document file with the latest update date. The document is transferred to the document creation unit 9 (step S05). In the above example of the URL, if the revision number “rev1” is not specified, the file search unit 8 writes the file name “a0010003.html” of the original document file having the latest update date to the document creation unit 9 Transfer to
[0028]
If the revision number is specified, the file search unit 8 refers to the item of the document name and the revision number in the content database 2 and determines whether or not the original document file of the revision number exists (step S06).
[0029]
If the original document file with the revision number exists, the file name of the original document file indicated by the revision number is obtained and transferred to the document creation unit 9 (step S07). In the above URL example, since the revision number “rev1” is specified, the file search unit 8 sends the file name “a001001.html” of the original document file of the revision number “rev1” to the document creation unit 9. Forward.
[0030]
If the information of the revision number does not exist, an error message indicating that the information does not exist is returned to the client 5 (step S08).
[0031]
The document creation unit 9 searches the document database 3 using the file name of the original document file acquired by the file search unit 8, acquires a document file corresponding to the file name, and transfers it to the transmission / reception unit 6 (step). S09).
[0032]
The transmission / reception unit 6 transmits the document file transferred from the document creation unit 9 to the client 5 as a document file specified in the URL (Step S10). In the case of the above URL, “a001001.html” is transmitted to the client 5 as “part1.html”.
[0033]
By recording the document file together with the revision number in this way, the document file corresponding to the revision number can be transmitted to the client. Therefore, any document file including the old document file before revision can be accessed from the client.
