Abstract

A document management apparatus according to the present invention performs storing, in response to a document registration request from an information processing apparatus, a document entity of the document, acquiring document information of the document, and storing data of a type determined based on the acquired document information, as a preview-image document of the document, and determining, upon reception of an acquisition request for the preview-image document from the information processing apparatus, whether the preview-image document stored in the preview-image document storage unit or the document entity stored in the document entity storage unit is to be transmitted based on a state of the document management apparatus, and transmitting data determined to be transmitted.

Claims

1. A document management apparatus connectable with an information processing apparatus configured to transmit a document registration request and an acquisition request for a document, the document management apparatus comprising:

a document entity storage unit configured to, in response to a document registration request from the information processing apparatus, store a document entity of the document;

an acquisition unit configured to acquire document information of the document;

a preview-image document storage unit configured to store data of a type determined based on the document information acquired by the acquisition unit, as a preview-image document of the document; and

a transmission unit configured to, upon reception of an acquisition request for the preview-image document from the information processing apparatus, determine whether the preview-image document stored in the preview-image document storage unit or the document entity stored in the document entity storage unit is to be transmitted based on a state of the document management apparatus, and transmit data determined to be transmitted.

2. The document management apparatus according to claim 1, wherein, when the document can be processed neither by the document management apparatus nor by the information processing apparatus, the preview-image document storage unit stores as the preview-image document a fixed image predefined in the document management apparatus.

3. The document management apparatus according to claim 1, wherein, when a size of the document is less than a predetermined value, the preview-image document storage unit stores a document entity of the document as the preview-image document.

4. The document management apparatus according to claim 1, wherein, when the document is a structured document and when a display document can be extracted from the structured document, the preview-image document storage unit stores the display document as the preview-image document.

5. The document management apparatus according to claim 1, wherein, when a size of the document is larger than a predetermined size and when the document management apparatus can generate an image having a lower resolution than a document entity of the document, the preview-image document storage unit stores a low-resolution image of a starting page of the document as a preview-image document.

6. The document management apparatus according to claim 1, wherein, when a size of the document is larger than a predetermined size, when the document management apparatus can generate an image having a lower resolution than a document entity of the document, and when the document is a dividable document, the preview-image document storage unit stores a divided document in one starting page of the document as a preview-image document.

7. The document management apparatus according to claim 1, wherein, when the document acquisition request is an acquisition request for the preview-image document and when the number of pieces of processing being currently executed for the preview-image document acquisition requests does not reach a threshold value, the transmission unit transmits the document entity to the information processing apparatus.

8. The document management apparatus according to claim 1, wherein, when the document acquisition request is an acquisition request for the preview-image document and when the document management apparatus is in a heavy-loaded state, the transmission unit transmits to the information processing apparatus an image indicating the heavy-loaded state of the document management apparatus, prestored in the document management apparatus.

9. The document management apparatus according to claim 1, wherein, when the document acquisition request is an acquisition request for the preview-image document and when among processing being currently executed for preview-image document acquisition requests by the document management apparatus, a number of processing for acquisition requests from an identical information processing apparatus does not reach a threshold value, the transmission unit transmits the document entity to the information processing apparatus.

10. A method for controlling a document management apparatus connectable with an information processing apparatus configured to transmit a document registration request and an acquisition request for a document, the method comprising:

storing, in response to a document registration request from the information processing apparatus, a document entity of the document;

acquiring document information of the document;

storing data of a type determined based on the acquired document information, as a preview-image document of the document; and

determining, upon reception of an acquisition request for the preview-image document from the information processing apparatus, whether the preview-image document or the document entity is to be transmitted based on a state of the document management apparatus, and transmitting data determined to be transmitted.

11. A computer-readable storage medium storing a computer-executable process, the computer-executable process causing a processor of a document management apparatus to execute a method comprising:

storing, in response to a document registration request from the information processing apparatus, a document entity of the document;

acquiring document information of the document;

storing data of a type determined based on the acquired document information, as a preview-image document of the document; and

determining, upon reception of an acquisition request for the preview-image document from the information processing apparatus, whether the preview-image document or the document entity is to be transmitted based on a state of the document management apparatus, and transmitting data determined to be transmitted.
