Deleting a document from a document group based on time conditions
View Patent ↗A document management apparatus includes a generating unit, a setting unit, a determining unit, and a deleting unit. The generating unit generates a new document from a base document. The setting unit sets the new document as a document which belongs to a document group to which the base document belongs. The determining unit determines whether or not a document group to which a selected document belongs includes a document which was generated or last viewed less than a reference time period ago. The deleting unit deletes the selected document if the document group does not include a document which was generated or last viewed less than the reference time period ago, and does not delete the selected document if the document group includes a document which was generated or last viewed less than the reference time period ago.
1. A document management apparatus comprising:
a generating unit that generates a new document from a base document;
a setting unit that sets the new document as a document which belongs to a document group to which the base document belongs, that performs, if the base document does not belong to any document group, setting for creating a document group to which the base document and the new document belong, and that performs, if the base document belongs to a certain document group, setting for adding the new document to the certain document group;
a determining unit that determines, if a document which belongs to a document group created by the setting unit is selected, whether or not the document group to which the selected document belongs includes a document which was generated or last viewed less than a reference time period ago; and
a deleting unit that deletes the selected document if the document group to which the selected document belongs does not include a document which was generated or last viewed less than the reference time period ago, and that does not delete the selected document if the document group to which the selected document belongs includes a document which was generated or last viewed less than the reference time period ago.
2. The document management apparatus according to claim 1 , further comprising:
a specifying unit that specifies a portion of the selected document, the portion being included in an original document which is a document in the document group to which the selected document belongs and which is a document generated before the selected document,
wherein the deleting unit deletes the specified portion from the selected document if the document group to which the selected document belongs includes a document which was generated or last viewed less than the reference time period ago.
3. The document management apparatus according to claim 1 , further comprising:
a specifying unit that specifies a portion of the selected document, the portion not being included in an original document which is a document in the document group to which the selected document belongs and which is a document generated before the selected document; and
a generating unit that generates a document which includes the specified portion if the document group to which the selected document belongs does not include a document which was generated or last viewed less than the reference time period ago.
4. A document management method comprising:
generating a new document from a base document;
setting the new document as a document which belongs to a document group to which the base document belongs, performing, if the base document does not belong to any document group, setting for creating a document group to which the base document and the new document belong, and performing, if the base document belongs to a certain document group, setting for adding the new document to the certain document group;
determining, if a document which belongs to a document group created by the setting is selected, whether or not the document group to which the selected document belongs includes a document which was generated or last viewed less than a reference time period ago; and
deleting the selected document if the document group to which the selected document belongs does not include a document which was generated or last viewed less than the reference time period ago, and not deleting the selected document if the document group to which the selected document belongs includes a document which was generated or last viewed less than the reference time period ago.
5. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
generating a new document from a base document;
setting the new document as a document which belongs to a document group to which the base document belongs, performing, if the base document does not belong to any document group, setting for creating a document group to which the base document and the new document belong, and performing, if the base document belongs to a certain document group, setting for adding the new document to the certain document group;
determining, if a document which belongs to a document group created by the setting is selected, whether or not the document group to which the selected document belongs includes a document which was generated or last viewed less than a reference time period ago; and
deleting the selected document if the document group to which the selected document belongs does not include a document which was generated or last viewed less than the reference time period ago, and not deleting the selected document if the document group to which the selected document belongs includes a document which was generated or last viewed less than the reference time period ago.
