Information-processing apparatus, information-processing system, information-processing method, computer-readable medium, and computer data signal

A computer-readable medium storing a program causing a computer to execute a process for document provision, the program causing the computer to function as:

• a registration unit that receives log information including information concerning an operator that performed an operation with respect to a first document, time and date of the operation, and a second document obtained as a result of the operation, from a first information-processing apparatus, and registers the log information in a storage unit, the registration unit, when the first document is already registered in the storage unit, further registering in the storage unit a derivation relationship indicating that the first document is a parent of the second document;
• and
• a document-providing unit that, in response to a collection instruction including information that specifies a subject document, specifies and provides a latest version document with regard to each operator from documents included in a tree to which the subject document belongs among trees formed by derivation relationships stored in the storage unit, on the basis of the log information.

An information-processing system comprising a first information-processing apparatus and a second information-processing apparatus,

• the first information-processing apparatus including a sending unit that sends log information including information concerning an operator that performed an operation with respect to a first document, time and date of the operation, and a second document obtained as a result of the operation;
• and
• the second information-processing apparatus including a registration unit that receives the log information from the first information-processing apparatus and registers the log information in a storage unit, the registration unit, when the first document is already registered in the storage unit, further registering in the storage unit a derivation relationship indicating that the first document is a parent of the second document, and a document-providing unit that, in response to a collection instruction including information that specifies a subject document, specifies and provides a latest version document with regard to each operator from documents included in a tree to which the subject document belongs among trees formed by derivation relationships stored in the storage unit, on the basis of the log information.

A computer data signal embodied in a carrier wave for enabling a computer to perform a process for document provision, the computer data signal causing the computer to function as:

• a registration unit that receives log information including information concerning an operator that performed an operation with respect to a first document, time and date of the operation, and a second document obtained as a result of the operation, from a first information-processing apparatus, and registers the log information in a storage unit, the registration unit, when the first document is already registered in the storage unit, further registering in the storage unit a derivation relationship indicating that the first document is a parent of the second document;
• and
• a document-providing unit that, in response to a collection instruction including information that specifies a subject document, specifies and provides a latest version document with regard to each operator from documents included in a tree to which the subject document belongs among trees formed by derivation relationships stored in the storage unit, on the basis of the log information.
