New Generation Sensor Web Enablement
TLDR
The recent developments of the new generation of the Sensor Web Enablement specification framework are illustrated and related to other emerging concepts such as the Web of Things and point out challenges and resulting future work topics for research on Sensor Web enablement. Expand
Discovery Mechanisms for the Sensor Web
TLDR
An approach will be presented that was developed within the EU funded project “OSIRIS” that offers mechanisms to search for sensors, exploit basic semantic relationships, harvest sensor metadata and integrate sensor discovery into already existing catalogues. Expand
Enabling IoT Ecosystems through Platform Interoperability
TLDR
The BIG IoT (Bridging the Interoperability Gap of the IoT) project aims to ignite an IoT ecosystem as part of the European Platforms Initiative and employs five interoperability patterns that enable cross-platform interoperability and can help establish successful IoT ecosystems. Expand
Semantically-Enabled Sensor Plug & Play for the Sensor Web
TLDR
A Sensor Plug & Play infrastructure for the Sensor Web is introduced by combining semantic matchmaking functionality, a publish/subscribe mechanism underlying the SensorWeb, as well as a model for the declarative description of sensor interfaces which serves as a generic driver mechanism. Expand
enviroCar: A Citizen Science Platform for Analyzing and Mapping Crowd-Sourced Car Sensor Data
TLDR
The enviroCar platform for collecting geographic data acquired from automobile sensors and openly providing those data for further processing and analysis is presented, and the description of the spatiotemporal RESTful Web Service interface and underlying data model specifically designed for handling the mobile sensor data is presented. Expand
The BIG IoTAPI -Semantically Enabling IoT Interoperability
TLDR
The generic BIG IoT API is presented that employs a novel approach for self-description and semantic annotation to fully adapt arbitrary IoT platforms to enable interoperable interaction with those platforms. Expand
An Architecture for Interoperable IoT Ecosystems
TLDR
The BIG IoT architecture is presented as the foundation to establish IoT ecosystems and fulfills essential requirements that have been assessed among industry and research organizations as part of the BIG IoT project. Expand
SenseBox - A Generic Sensor Platform for the Web of Things
TLDR
This work introduces the SenseBox, a small computing device equipped with different sensors to perceive its environment and with a Web server and an according REST API which makes it available as a first class citizen on the Web. Expand
Future SDI - Impulses from Geoinformatics Research and IT Trends
TLDR
A conceptual view of the dynamics of both SDIs and the Geospatial Web is given, and a picture of the SDI of the future is presented, one which benefits from these developments, based on an analysis of geoinformatics research topics and current ICT trends. Expand
Semantic Enablement for Spatial Data Infrastructures
TLDR
Instead of developing new semantically enabled services from scratch, this work proposes to create profiles of existing services that implement a transparent mapping between the OGC and the Semantic Web world, and points out how to combine SDI with linked data. Expand
