A storage medium readable by a computer stores a program of instructions executable by the computer to perform a function for supporting editing of a hierarchical structure of a directory. The function includes: editing metadata including information relevant to the hierarchical structure of the directory; editing content data as contents of a document; analyzing the metadata; and creating a new hierarchical structure of the directory on the basis of a result of the analysis and the content data.

Storage medium storing directory editing support program, directory editing support method, and directory editing support apparatus

Both of a user side and a protect side such as a programmer of an application programmer need not handle a large number of inherent information such as authentication keys. An access ticket generation device generates an access ticket from user unique identifying information and access rights authentication feature information. As unique security characteristic information, there is used a secret key of an elliptic curve encryption or an ElGamal encryption. A proof data generation device receives the access ticket, converts authentication data received from a proof data verification device into proof data by use of the access ticket and the user unique identifying information, and returns the resultant proof data to the proof data verification device. The proof data generation device or the proof data verification device decrypts the above-mentioned encryption. The proof data verification device verifies the access rights as correct access only when a combination of an access ticket and user unique identifying information used in the proof data generation device is correct.

A mechanism for connecting ornamental parts of wrist watches that permit easily connecting and disconnecting ornamental parts without using any special tool and without marring the appearance of wrist watches. A stepped pin is inserted in a larger-diameter bore of a cocoon-shaped ring fitted in an end piece and a bore in a watch casing. Then, a smaller-diameter part of the stepped pin is moved into a smaller-diameter bore by pulling the watch casing and a band longitudinally. With the stepped pin thus securely held in place, the watch casing and band are firmly connected.

A work station apparatus includes an electronic mail function. In the work station apparatus, a transmission box icon and object icons indicative of objects to be transmitted are displayed on the display screen of a display unit, and an instruction for transmitting an electronic mail is given in a manner such that a desired object icon is selected from the object icons and is placed on the transmission box icon. The work station apparatus includes a storing unit for storing the destination data set in connection with the transmission box icon, a developing unit for developing the destination data into destination data of the data body corresponding to the object icon in response to the instruction for transmitting the electronic mail, and a transmitting unit for performing a transmission process of the data body according to the developed destination data.
