Abstract

Disclosed are an electronic device and a non-transitory computer-readable storage medium. Conventionally, most of institutions, companies, etc. have defined and used their own data standards for the business purposes. Most of the data is stored in relational database in a structured format. Now as convergence between industries, new business and new data increases, an active data management system is becoming necessary. The electronic devices according to the disclosure can provide data hub device providing automatically extendable data management function interworking with an open data reference model management device (an active metadata management). Accordingly, the data hubs can exchange standardized data maps among them so as to quickly adapt to such changes in the open industry environment.

First claim

What is claimed is:

1. An electronic device comprising:
an open data reference model management device configured to subdivide and manage a classification system for each domain of an open data reference model into categories of a hierarchical structure; and
a data hub device configured to:
collect a first dataset based on the open data reference model;
store the first dataset; and
generate a first data map based on the first dataset;
detect a change in the open data reference model and perform the changed open data reference model;
collect a second data map from an external data hub device and change the second data map based on a first profile specification of the open data reference model;
synchronize data map information between the data hub device and the external data hub device; and
generate event information in response to a change in the data map information of the data hub device by synchronizing the data map information and load the event information onto a queue in a data map synchronization unit of the data hub device,
wherein profile information of the first dataset includes metadata information of a profile specification of a first category of the open data reference model and metadata information of a profile specification of a second category, which is an upper category of the first category, and
wherein the queue is accessed periodically by the external data hub device.

2. The electronic device of claim 1 , wherein the open data reference model management device includes an extension request input unit configured to receive an extension request for the open data reference model from an outside of the electronic device, and
wherein the extension request includes a request for adding, modifying or deleting one of a domain, a classification system, or a category for the open data reference model.

3. The electronic device of claim 2 , wherein the open data reference model management device further includes an open data reference model management unit configured to manage the open data reference model in response to the extension request, and
wherein the open data reference model management unit includes:
an extension management unit configured to receive the extension request and a metadata schema corresponding to the extension request from the extension request input unit;
a domain management unit configured to receive the extension request and the metadata schema from the extension management unit and to modify a domain of the open data reference model based on the extension request and the metadata schema;
a classification system management unit configured to modify a classification system of the domain based on the open data reference model modified by the domain management unit, the extension request, and the metadata schema;
a category management unit configured to modify a category of the classification system based on the open data reference model further modified by the classification system management unit, the extension request, and the metadata schema; and
a profile management unit configured to modify a profile specification of the category based on the open data reference model further modified by the category management unit, the extension request, and the metadata schema.

4. The electronic device of claim 3 , wherein the open data reference model management unit further includes:
a version management unit configured to modify a version of the open data reference model based on the open data reference model further modified by the profile management unit; and
a dictionary management unit configured to register a term, a word, a vocabulary, or a code in a dictionary of the open data reference model based on the open data reference model further modified by the profile management unit.

5. The electronic device of claim 3 , wherein the open data reference model management unit further includes:
an open data reference model storage configured to store the open data reference model further modified by the profile management unit.

6. The electronic device of claim 1 , wherein the open data reference model management device further includes:
an operating environment management unit configured to manage operating environments of a first device managing a first domain of the open data reference model, a second device managing a first classification system of the first domain, a third device managing a second classification system of the first domain, and a fourth device managing a first category of the first classification system; and
a reference model synchronization unit configured to direct synchronization between two devices among the first to fourth devices,
wherein the reference model synchronization unit is further configured to direct synchronization between the second device and the fourth device and synchronization between the second device and the first device in response to modification of the first classification system of the open data reference model.

7. The electronic device of claim 1 , wherein the open data reference model management device further includes:
a data hub management unit configured to manage the data hub device based on a topic of interest of the data hub device;
a data hub synchronization unit configured to perform synchronization with the data hub device in response to extension of the open data reference model; and
a data hub reference service unit configured to provide the data hub device with information of the open data reference model in response to a request of the data hub device, and
wherein the topic of interest of the data hub device is at least one of a domain, a classification system, and a category of the open data reference model.

8. The electronic device of claim 1 , wherein the data hub device includes:
a reference model topic management unit configured to register information associated with a topic of interest of the data hub device in the open data reference model management device.

9. The electronic device of claim 1 , wherein the data hub device includes:
a reference model synchronization unit configured to detect the change in the open data reference model by the open data reference model management device and to perform synchronization of the changed open data reference model.

10. The electronic device of claim 1 , wherein the data hub device includes:
a reference model service unit configured to make a request for information of the open data reference model to the open data reference model management device and to receive the requested information.

11. The electronic device of claim 10 , wherein the data hub device further includes:
an open data reference model storage configured to store the requested information.

12. The electronic device of claim 1 , wherein the data hub device includes:
a data hub management unit configured to register information of the data hub device in the external data hub device and to register information of the external data hub device in the data hub device; and
a data map collection unit configured to collect the second data map from the external data hub device based on the open data reference model and to change the second data map based on the first profile specification of the open data reference model.

13. The electronic device of claim 12 , wherein the data hub device includes:
the data map synchronization unit, the data map synchronization unit being configured to synchronize the data map information between the data hub device and the external data hub device.
