SensorThings API is an Open Geospatial Consortium (OGC) standard providing an open and unified framework to interconnect IoT sensing devices, data, and applications over the Web. It is an open standard addressing the syntactic interoperability and semantic interoperability of the Internet of Things. It complements the existing IoT networking protocols such CoAP , MQTT , HTTP , 6LowPAN . While the above-mentioned IoT networking protocols are addressing the ability for different IoT systems to exchange information, OGC SensorThings API is addressing the ability for different IoT systems to use and understand the exchanged information. As an OGC standard, SensorThings API also allows easy integration into existing Spatial Data Infrastructures or Geographic Information Systems .

Various types of widgets can be arranged and configured on the dashboard. It is a web application and can be embedded into any website. A live demo is available on

6699-438: The reauthorization of DHS, Deputy Secretary Elaine Duke said there is a weariness and anxiety within DHS about the repeated congressional efforts to agree to a long-term spending plan, which had resulted in several threats to shut down the federal government. "Shutdowns are disruptive", Duke said. She said the "repeated failure on a longtime spending plan resulting in short-term continuing resolutions (CRs) has caused "angst" among

6786-593: The semantic middleware developed in the Horizon 2020 ECSEL project AFarCloud . It is a modular Java application with Docker-based deployment, implemented according to the 15-078r6 OGC SensorThings API 1.0 Implementation Standard. SensorThings API provides functions similar to the OGC Sensor Observation Service , an OGC specification approved in 2005. Both standard specifications are under the OGC Sensor Web Enablement standard suite. The following table summarizes

6873-709: The system architecture, it gains desirable non-functional properties , such as performance, scalability, simplicity, modifiability, visibility, portability, and reliability. The formal REST constraints are as follows: The uniform interface constraint is fundamental to the design of any RESTful system. It simplifies and decouples the architecture, which enables each part to evolve independently. The four constraints for this uniform interface are: Several models have been developed to help classify REST APIs according to their adherence to various principles of REST design, such as Department of Homeland Security The United States Department of Homeland Security ( DHS )

6960-477: The technical difference between the two specifications. REST This is an accepted version of this page REST ( Re presentational S tate T ransfer) is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web .

7134-409: The time, there was only a fragmented description of the Web's architecture, and there was pressure in the industry to agree on some standard for the Web interface protocols. For instance, several experimental extensions had been added to the communication protocol (HTTP) to support proxies , and more extensions were being proposed, but there was a need for a formal Web architecture with which to evaluate

7221-674: Was built on the template of the NIMS. On January 22, 2008, the National Response Framework was published in the Federal Register as an updated replacement of the NRP, effective March 22, 2008. The Post-Katrina Emergency Management Reform Act directs the DHS Secretary to designate employees from throughout the department to staff a Surge Capacity Force (SCF). During a declared disaster, the DHS Secretary will determine if SCF support

The bill was also controversial for the presence of unrelated " riders ", as well as for eliminating certain union-friendly civil service and labor protections for department employees. Without these protections, employees could be expeditiously reassigned or dismissed on grounds of security, incompetence or insubordination, and DHS would not be required to notify their union representatives. The plan stripped 180,000 government employees of their union rights. In 2002, Bush officials argued that

7395-413: Was introduced and defined in 2000 by computer scientist Roy Fielding in his doctoral dissertation. It means that a server will respond with the representation of a resource (today, it will most often be an HTML , XML or JSON document) and that resource will contain hypermedia links that can be followed to make the state of the system change. Any such request will in turn receive the representation of

7482-429: Was poorly planned, time-consuming for analysts to use, and lacked adequate justifications. Fusion centers are terrorism prevention and response centers, many of which were created under a joint project between the Department of Homeland Security and the U.S. Department of Justice 's Office of Justice Programs between 2003 and 2007. The fusion centers gather information from government sources as well as their partners in

7569-435: Was the use, from 2002, of the phrase "the homeland" by White House spokespeople. In 2011, the Department of Homeland Security phased out the old Homeland Security Advisory System, replacing it with a two-level National Terrorism Advisory System.
