Provided is an information processing system that shares data between organizations A and B and performs processing. The information processing system includes a data processing apparatusand data input/output apparatusesA andB that manage data in the respective organizations. The data processing apparatusincludes a schema information sharing unitthat allows sharing of schemas between the organizations A and B, the schemas specifying the data structures of data held by the respective organizations A and B, an agreement forming unitthat receives a data processing proposal that indicates the range of sharing data to be shared between the organizations A and B, and the processing using the sharing data as an input, and forms agreement to the data processing proposal by obtaining approval to the data processing proposal from each organization, and a processing executing unitthat acquires the sharing data indicated by the data processing proposal regarding which agreement has been formed from the organizations A and B, and executes the processing indicated by the data processing proposal. The data input/output apparatusesA andB each include a proposing unitthat transmits the data processing proposal to the data processing apparatus, an approving unitthat transmits approval to the data processing proposal to the data processing apparatus, and a data transmitting unitthat transmits the sharing data indicated by the data processing proposal to the data processing apparatus

An information processing apparatus according to an embodiment includes: a creation processing unit which creates information indicating a message structure based on which a length of a memory area to be secured in a stack area of a virtual address space assigned for a serialization process is determined during compilation; a serialization processing unit which performs a serialization process to serialize data from a device and write the serialized data into a data storage device using the information created by the creation processing unit; and a deserialization processing unit which reads the serialized data written into the data storage device and deserializes the read data using the information created by the creation processing unit.

Information processing apparatus, method, and program

An information processing apparatus according to an embodiment includes: a common data model management unit that manages information indicating a common data model corresponding to a plurality of modules in common; a unique data model management unit that manages information indicating a unique data model corresponding to at least one of the modules; and a common management unit that manages a version of a module corresponding to the common data model managed by the common data model management unit, a version of a module corresponding to the unique data model managed by the unique data model management unit, and a version of a module corresponding to a newly installed data model, and verifies compatibility of the versions.

Version processing apparatus, method, and program

A message transmitting and receiving method according to one aspect is performed by a communication apparatus, the communication apparatus including a middleware unit configured to manage a message published by a publisher in a publish/subscribe system in which a message is exchanged between the publisher and a subscriber via a broker, and a storage unit configured to store a library including functions configured to provide the broker, and includes the steps of performing, by the middleware unit, subscribing on the broker by setting a callback function, and upon receipt of a first message published by a device, passing, by the broker, the first message to the middleware unit by calling the callback function.

Message transmitting and receiving method, communication apparatus, and program

Provided are a device control apparatus, a device control method, and a device control system which prevent a conflict from occurring in RPCs simultaneously transmitted from a plurality of applications to the same device, so that RPCs can be applied to exercise control over devices in an IoT system of a many-to-many connection which cannot accept non-completion of a series of processing operations in cooperation. The device control apparatus includes a memory () in which information on a device () and an identifier of the device () is stored, and a memory () in which authority of the devicefor each application () is stored. The device control apparatus includes a memory () configured to store information on a device () and an identifier of the device (), and a memory () configured to store authority for controlling the devicefor each application (). The apparatus, the method, and the system provide, in accordance with a request signal from, e.g., an application () control authority to the application (), if the application () has control authority for all devices () as a control object, and transmit a remote control signal from the application () to devices () as a control object while excluding a control authority for other applications () to control the devices ().
