Abstract

There is provided an information processing apparatus capable of merging a plurality of print documents having a hierarchical structure including layers to which metadata are attached. To achieve this capability, the information processing apparatus receives from a user an instruction for merging the plurality of print documents, changes the plurality of print documents, and then merges the plurality of print documents.

Claims

1. An information processing apparatus comprising:

a receiving unit configured to receive from a user an instruction for merging first and second print documents having a hierarchical structure including layers to which metadata are attached;

a determination unit configured to, in response to the instruction received by the receiving unit, determine whether a combination of keys included in metadata of the first print document coincides with a combination of keys included in metadata of the second print document with respect to each of the layers in the hierarchical structures of the first and second print documents;

a changing unit configured to, when the determination unit determines that the combination of keys included in the metadata of the first print document does not coincide with the combination of keys included in the metadata of the second print document, change at least one of the metadata of the first print document and the metadata of the second print document so that the combination of keys included in the metadata of the first print document coincides with the combination of keys included in the metadata of the second print document with respect to each of the layers in the hierarchical structures of the first and second print documents; and

a merging unit configured to merge the first and second print documents based on the metadata obtained through change processing by the changing unit.

2. The information processing apparatus according to claim 1, wherein, when the determination unit determines that the combination of keys included in the metadata of the first print document does not coincide with the combination of keys included in the metadata of the second print document, and that a common key is included in the metadata of the first and second print documents for a layer determined to be mismatched by the determination unit, the changing unit applies grouping to the layer determined to be mismatched, and wherein, when the determination unit determines that the combination of keys included in the metadata of the first print document does not coincide with the combination of keys included in the metadata of the second print document, and that no common key is included in the metadata of the first and second print documents for a layer determined to be mismatched by the determination unit, the changing unit cancels grouping of the layer determined to be mismatched, thus changing at least one of the metadata of the first print document and the metadata of the second print document.

5. The information processing apparatus according to claim 1, further comprising:

an updating unit configured to update printing control information for controlling printing corresponding to the print document formed after merging by the merging unit.

3. An information processing apparatus comprising:

a receiving unit configured to receives from a user an instruction for merging a plurality of print documents having a hierarchical structure including layers to which metadata are attached; and

a merging unit configured to acquire all keys of the metadata attached to the plurality of print documents, determine a hierarchical structure of a print document to be formed after merging, change the metadata of the plurality of print documents to achieve the determined hierarchical structure, and merge the plurality of print documents.

4. The information processing apparatus according to claim 3, wherein the merging unit further acquires all keys of the metadata attached to the plurality of print documents, determines whether all of the keys exist in the metadata attached to the plurality of print documents, and adds, for each of a plurality of insufficient documents having metadata in which any of all of the keys is nonexistent, the nonexistent key to the metadata of the insufficient documents.

6. A computer-readable recording medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

receiving from a user an instruction for merging first and second print documents having a hierarchical structure including layers to which metadata are attached;

determining, in response to the received instruction, whether a combination of keys included in metadata of the first print document coincides with a combination of keys included in metadata of the second print document with respect to each of the layers in the hierarchical structures of the first and second print documents;

changing, when the combination of keys included in the metadata of the first print document does not coincide with the combination of keys included in the metadata of the second print document, at least one of the metadata of the first print document and the metadata of the second print document so that the combination of keys included in the metadata of the first print document coincides with the combination of keys included in the metadata of the second print document with respect to each of the layers in the hierarchical structures of the first and second print documents; and

merging the first and second print documents based on the metadata obtained through change processing.

7. The recording medium according to claim 6, wherein, when the combination of keys included in the metadata of the first print document does not coincide with the combination of keys included in the metadata of the second print document, and that a common key is included in the metadata of the first and second print documents for a layer determined to be mismatched, the changing applies grouping to the layer determined to be mismatched, and wherein, when the combination of keys included in the metadata of the first print document does not coincide with the combination of keys included in the metadata of the second print document, and that no common key is included in the metadata of the first and second print documents for a layer determined to be mismatched, the changing cancels grouping of the layer determined to be mismatched, thus changing at least one of the metadata of the first print document and the metadata of the second print document.

8. The recording medium according to claim 6, wherein the recording medium further stores instructions that, when executed by the processor, cause the processor to perform operations comprising:

updating printing control information for controlling printing corresponding to the print document formed after merging by the merging unit.

9. A method for processing information, comprising:

receiving from a user an instruction for merging first and second print documents having a hierarchical structure including layers to which metadata are attached;

determining, in response to the received instruction, whether a combination of keys included in metadata of a first print document coincides with a combination of keys included in metadata of a second print document with respect to each of the layers in the hierarchical structures of the first and second print documents;

changing, when the combination of keys included in the metadata of the first print document is determined not to coincide with the combination of keys included in the metadata of the second print document, at least one of the metadata of the first print document and the metadata of the second print document so that the combination of keys included in the metadata of the first print document coincides with the combination of keys included in the metadata of the second print document with respect to each of the layers in the hierarchical structures of the first and second print documents; and

merging the first and second print documents based on the changed metadata.

10. The method according to claim 9, further comprising:

applying, when the combination of keys included in the metadata of the first print document is determined not to coincide with the combination of keys included in the metadata of the second print document, and a common key is included in the metadata of the first and second print documents for a layer determined to be mismatched, grouping to the layer determined to be mismatched; and

canceling, when the combination of keys included in the metadata of the first print document is determined not to coincide with the combination of keys included in the metadata of the second print document, and no common key is included in the metadata of the first and second print documents for a layer determined to be mismatched, grouping of the layer determined to be mismatched, thus changing at least one of the metadata of the first print document and the metadata of the second print document.

11. The method according to claim 9, further comprising:

updating printing control information for controlling printing corresponding to the print document formed after merging the first and second print documents.
