An API for a website is code that allows two software programs to communicate with each other. The API spells out the proper way for a developer to write a program requesting services from an operating system or other application. The REST used by browsers can be thought of as the language of the internet. With cloud use on the riseAPIs are being used by cloud consumers to expose and organize access to web services. Each module addresses a particular underlying part of the transaction. This modularity provides developers with a lot of flexibility, but it can be challenging for developers to design their REST API from scratch. With REST, networked components are a resource the user requests access to -- a black box whose implementation details are unclear. All calls are stateless; nothing can be retained by the RESTful service between executions. Because the calls are statelessREST is useful in cloud applications. Stateless components can be freely redeployed if something fails, and they can scale to accommodate load changes. This is because any request can be directed to any instance of a component; there can be nothing saved that has to be remembered by the next transaction. Roy Fielding in his doctorate dissertation. RESTful web services are stateless. REST services are useful for restricted profile devices, such as mobile, and are easy to integrate with existing websites. SOAP requires less plumbing code -- meaning low-level, infrastructural code that connects main code modules together -- than REST services design. The Web Services Description Language describes a common set of rules to define the messages, bindings, operations and location of the service. SOAP web services are useful for asynchronous processing and invocation. InRoy Fielding and a group of developers decided to create a standard so that any server could talk to any other server. These universal rules make it easier for developers to integrate software. This caught the attention of another ecommerce giant, and Amazon announced its API in

What is a Smart Building? A Smart Building leverages communication in order to operate efficiently and provide an enhanced user experience. What will differ however, is the road we travel in order to achieve those goals. The 21 st Century Smart Building consists of many different systems. We are now seeing a much greater demand placed upon the Systems Integrator than ever before. Here at One Sightsolutions, we find ourselves working with so many different systems on a daily basis that we probably lose count sometimes. But thanks to the experience we have gained working through these challenges presented by the modern Smart Building, we understand that when you combine the right skillsets with the right tools, the only real limitations are caused not by technology… but rather those that you create yourself. Niagara 4 from Tridium is at the very core of what we do here at One Sightsolutions. Most importantly, Niagara 4 is a platform built around the concept of open standards and communication. Where do you go? One things for sure, these services are in demand and therefore the modern day Systems Integrator should expect to be asked to ensure their system can exchange data with such systems in advance. Infact you may find more often than not, that the requirements of connectivity to these new breed of systems are left open ended and that limited information will be available to you as an integrator until agreements have been signed, fees paid and a business relationship established. Niagara 4 provides a platform upon which there is scope for unlimited integration potential. We know this simply by looking at the evolution of building system protocols and the installation of building systems onto fully managed and converged Ethernet networks. This is the standard for data exchange for just about all modern web services, as well as the vast majority of IoT devices that have an IP connection themselves. This is why being able to interact with them is going to be a vital part of any new Smart Building system, and also making your own data available in the same fashion for other systems. Bottom line? Niagara 4. Expect the Unexpected. This brings me onto the most important 3 letter acronym in our industry right now. Enjoyed this post? Give it a share.

Niagara Dev: Add 3rd Party Jar to Eclipse


Using NHaystack, external applications receive data that includes essential meta data tags to describe the meaning of the data. When acting as a server, NHaystack automatically generates standard tags for all the ControlPoints in your system. This feature allows for connecting immediately to the Niagara Station via Haystack once the NHaystack module has been installed, without requiring any further configuration. It makes discovering the points in your station as easy as issuing a simple query. NHaystack-as-a-server also streamlines the process of adding user-specified Haystack tags to Niagara systems, by providing a GUI tool that allows users to add the tags directly to Niagara components. Once tags have been defined, the data associated with the Niagara components, including the tags, are available over the REST communications interface. This combination of the tagging tool and the Haystack protocol "engine" reduces the effort involved in connecting Niagara data to external software applications. NHaystack can also act as a Haystack client, via a Niagara 4 driver that models remote servers as Niagara devices. This allows Haystack devices to exist "underneath" stations. See Section 7 of this document for an explanation of how that works. The nhaystack distribution archive comes with 2 modules and a patched haystack-rt. Next, select the patched version of the haystack-rt. The new version of nhaystack is not supported before version 4. If you are using a later version and a patched haystack-rt. If the Niagara 4 installation is a Web Supervisor then all you need to do is restart any running stations on the platform, connect to the stations and drop the NHaystackService into the running station. For use on a "Jace" style platform the minimum installation required is for the nhaystack-rt. Only install nhaystack-wb. To install the modules on a "Jace" type of platform, use the standard Niagara Workbench tools. As indicated above, a patched version of the haystack-rt. This must also be installed on the target platform. To get started with exposing a Niagara 4 station as a Haystack server, install nhaystack-rt. This is all you need to do to get rolling. Many of the tags that are defined as being associated with pointslike kindunittzhiscuretc. When you first add the NHaystackService to your station it needs to be enabled. When the service initialises it builds the in-memory cache of the Haystack records it finds. This process also happens when the station is started or restarted. If you examine the output from the Application Director of your station you will see a number of messages logged there advising of the status of the cache building process. This can be done by finding the NHaystackService in your station and right-clicking on the service. If you do not do this then your changes will not appear in any queries to the NHaystackService from either internal or external clients. When using the NHaystack module in Niagara and configuring your station as a Haystack server you will most likely want to enable the servlet. This servlet enables external Haystack clients to interact with your Niagara Station. Additionally there is an opportunity to provide a custom name for the servlet.

I see two options; Which one is correct:. Niagara installations can be configured to process many different network control protocols driven by an external process across the network, for example by BACnet. The Niagara instance can be configured internally in many different ways to respond to control from across the network. Niagara 4. For any real complexity beyond the bundled network drivers or HTTP, 3rd party modules coded in Java are used. These would typically be coded as Niagara drivers, processing data over serial or sockets. Niagara's APIs are mostly open. But Niagara is a complex environment. You'll have to add the oBIX service and export the points you want to see. Bajascript is a javascript library Tridium uses to interact with the system as well. I believe they released Bajascript 2. If those don't do what you like, you'll more than likely need to write your own API to handle it. How are we doing? Please help us improve Stack Overflow. Take our short survey. Learn more.
