Relation between a observation and it sensor.
observed by
A datatype property that encodes values from a datatype for an Entity. There are several ways to encode values in DOLCE (Ultralite): 1) Directly assert an xsd:_ value to an Entity by using hasDataValue 2) Assert a Region for an Entity by using hasRegion, and then assert an xsd:_ value to that Region, by using hasRegionDataValue 3) Assert a Quality for an Entity by using hasQuality, then assert a Region for that Quality, and assert an xsd:_ value to that Region, by using hasRegionDataValue 4) When the value is required, but not directly observed, assert a Parameter for an xsd:_ value by using hasParameterDataValue, and then associate the Parameter to an Entity by using isConstraintFor 5) When the value is required, but not directly observed, you can also assert a Parameter for a Region by using parametrizes, and then assert an xsd:_ value to that Region, by using hasRegionDataValue The five approaches obey different requirements. For example, a simple value can be easily asserted by using pattern (1), but if one needs to assert an interval between two values, a Region should be introduced to materialize that interval, as pattern (2) suggests. Furthermore, if one needs to distinguish the individual Quality of a value, e.g. the particular nature of the density of a substance, pattern (3) can be used. Patterns (4) and (5) should be used instead when a constraint or a selection is modeled, independently from the actual observation of values in the real world.

After a thorough analysis of existing Internet of Things (IoT) related ontologies, we propose FIESTA-IoT Ontology that aims to achieve semantic interoperability among heterogeneous testbeds. The Ontology is framed within the EU H2020's FIESTA-IoT project, that aims to seamlessly support the federation of testbeds through the usage of semantic-based technologies. The FIESTA-IoT ontology takes inspiration from the well-known Noy et al. methodology for reusing and interconnecting existing ontologies. To build the ontology, we leverage a number of core concepts from various mainstream ontologies and taxonomies, such as Semantic Sensor Network (SSN), M3-lite (a lite version of M3 ontology), WGS84, IoT-lite, Time, and DUL ontology.

Many testbeds owning devices or applications interacting with the sensors, store their inherent observations and other related data in their own proprietary format. In other words, making a testbed independent and isolated from others that cannot directly interact with each other. Differences in the data format lead to interoperability issues between the testbeds and much work has to be done in order to ensure the compatibility. One has to understand different data formats and create the mapping between them. As a result, a testbed must understand other testbed's format and create the mapping both while sending and receiving information. One method to accomplish interoperability is through the usage of semantic-based technologies to annotate all the information shared by the platforms. Nevertheless, some of the relevant existing ontologies promise interoperability but: - do not address the problem to describe the observation in an interoperable manner to ease further tasks, such as reasoning, - many of them are domain-specific and cannot be applied across domains, - they have missing concepts and do not suffice the needs of the measurements provided by the sensors, and - many ontologies do not follow best practices making it hard to correctly interpret and reuse concepts. In order to address the above-mentioned limitations, we provide FIESTA-IoT ontology (a unified semantic model) that follows best practices. FIESTA-IoT Ontology is a merge of concepts from various ontologies such as IoT-lite, M3-lite Taxonomy, SSN, Time and DUL (see Figure 1). The FIESTA-IoT Ontology is diveded into 2 parts: resourse description and observations produced. One has to follow the Figure 2 and Figure 3, respectively, for understanding what all concepts are associated with resourse description and observation. Using such information testbeds can annotate their data to FIESTA-IoT specific requirements and the annotators developed can achieve FIESTA-IoT certification. For more detials please see: - R.

Electric current is the flow of electric charge. It is a base quantity in the International System of Units. Electric current is electric charge divided by time. Electric Current is the flow (movement) of electric charge. The amount of electric current through some surface, e.g., a section through a copper conductor, is defined as the amount of electric charge flowing through that surface over time.

An Observation is a Situation in which a Sensing method has been used to estimate or calculate a value of a Property of a FeatureOfInterest. Links to Sensing and Sensor describe what made the Observation and how; links to Property and Feature detail what was sensed; the result is the output of a Sensor; other metadata details times etc.
Observation
skos:closeMatch 'observation' [O&M] http://www.opengeospatial.org/standards/om Observation in this ontology and O&M are described differently (O&M records an observation as an act/event), but they record the same thing and are essentially interchangeable. The difference is in the ontological structure of the two, not the data or use. Observation here records a Situation (the estimation of the value of a Property) and a description of the method that was used (along with the participants), while O&M interprets an Observation as the event itself; there must, however, have been an event that lead to our situation, so both are records of events. The distinction is between the event itself and the record of what happened in that event. skos:closeMatch 'measurement result' [VIM 2.9] http://www.bipm.org/utils/common/documents/jcgm/JCGM_200_2008.pdf Measurement result in VIM is the measured value plus any other relevant information, which means that measurement result and observation will often be associated to the same data (a value, a time, a property, etc.).

A Service (Class: Service) is a electronic representation of a Functionality in a network. The Service exposes the Functionality to the network and makes it discoverable, registerable and remotely controllable in the network. A Service is offered by a device that wants (a certain set of) its Functionalities to be discoverable, registerable, remotely controllable by other devices in the network. A Service can expose one or more Functionalities and a Functionality can be exposed by one or more Services. The Input- and Output DataPoints and Operations of a Service may have the same names as for a different Service, however the Service to which they belong differentiates how they are addressed in the Device (e.g. via a port specific to the Service). NOTE: While a Functionality describes the – human understandable – meaning of a Service of the device the Service is used to describe how such functionality is represented in a communication network and can be accessed by electronic means. The Service and its Operations is therefore dependent on the technology of the network, hard- and software of the device.
