| Issue | Key factor | Consideration |
|
| • Supporting openness | • Metadata | • Objects in the real world are nonunified to describe characteristics and implement interfaces for various domains. |
| • Datasets are individually structural, different, or unstructured formats..... |
| • Knowledgebase | • Metadata concepts provide possible solutions for the openness issues. |
| • Lack of guidelines for handling context as data enrichment | • Behavior how datasets are processed | • Sensing values can be collected and managed in generalized behaviors. |
| • Building up information sets into equivalent abstraction level | • Each processing phase has independent concepts or equations for measurement units. |
| • Readability for users and relevant systems | • Processed results should be represented and interpreted in a simplified form to overcome individually different query usages. |
| • Functionalities provision for nonskilled users | • ROS-based functionalities | • ROS-based functionalities consist of combinations of nodes, topics, and messages. |
| • Interfaces for readability | • Rosbridge is one of open-source projects that interconnect with both ROS and non-ROS operating systems. |
| • Resolving conflicts for service developers and users | • Relevant surrounding information sets, such as how to control robots or manage services, should be provided as a metadata element. Then, they help to provide a broad view of implementation to the nonskilled users. |
