Glossary and Terminology
| Term | Meaning |
|---|---|
| (OpenIoT) Architecture | The set of software and middleware components of the OpenIoT platform, along with the main structuring principles and inter-relationships driving their integration in an IoT-cloud platform. |
| (OpenIoT) Middleware | System level software (compliant to the OpenIoT architecture), which facilitates the integration of on-demand cloud-based IoT services. |
| (OpenIoT) Platform | A set of middleware libraries and tools, which enable the development and deployment of (OpenIoT compliant) cloud-based IoT services. |
| (OpenIoT) Use Case | A goal or application serving needs of end users, which is implemented based on the OpenIoT platform. |
| (OpenIoT) Service | An IoT service deployed over the OpenIoT platform. |
| (OpenIoT) Scenario | A specific set of interactions between OpenIoT components serving the needs of an application. |
| (OpenIoT) Cloud | A set of computing resources enabling the delivery of IoT services over the network and based on the use of OpenIoT platform. |
| Global Scheduler | A software component that regulates how IoT services access the different resources managed by the OpenIoT platform. |
| Utility Metrics | A set of measures contributing to the overall value and performance of IoT services |
| (OpenIoT) Service Delivery | The process of deploying and offering an OpenIoT service, after selecting the resources that are involved in the service. |
| (OpenIoT) Request Presentation | Software components that visualize the outcomes of an OpenIoT service based on the use of appropriate mashups and mashup libraries. |
| Sensor Selection | The process of selecting sensors that can contribute information to a particular service. |
| Virtual Sensor | All the physical or virtual items (i.e. services, persons, sensors, GSN nodes) which provide their information through a GSN endpoint. |
| Sensor Discovery | The process of detecting physical and virtual sensors, as well as of the services offered by them. |
| Resource Discovery | The process of detecting an IoT resource (such as a sensor, service or database). |
| Sensor Directory | A software service which stores, organizes and provides access to information about (physical and virtual) sensors. |
| (OpenIoT) Sensor Middleware | A part of the OpenIoT middleware platform that facilitates access to, collection and filtering of OpenIoT data streams. |
| Global Sensor Networks (GSN) | An open source sensor middleware platform enabling the development and deployment of sensor services with almost zero-programming effort. |
| Data Stream | A stream of digital information stemming from a physical or virtual sensor. |
| Linked Sensor Data | A set of Semantic Web technologies for exposing, sharing, and connecting sensor data, information, and knowledge. |
