Rich Semantic Internet Applications with Flex

After evaluating AJAX and OpenLaszlo for a while we have finally chosen Flash, in particular Flex 2 and ActionScript 3

Holger Knublauch's Blog

Rich Internet Applications (RIAs) run inside web browsers and provide a much more dynamic user experience than conventional web pages. While traditional HTML-based pages require a full reload of the page when the user clicks on a link, many modern web pages only reload parts of the page and provide animations to dynamically navigate through an information space.

There are several platforms to implement such dynamic web pages, for example AJAX, Flash, Java FX, Microsoft Silverlight, OpenLaszlo, XUL. These platform all share a similar programming model that mixes declarative (XML) elements to describe the layout of user interfaces with some imperative scripting to define the application's behavior.

For our newest Semantic Web tooling platform TopBraid Live we had to pick one of these technologies. The goal of TopBraid Live is to serve as development platform for Rich Internet Applications based on server-side Semantic Web models. TopBraid Live provides the whole server-side infrastructure to store and query RDF/OWL data, and a comprehensive client-side API including a library of out-of-the-box components that make creating web applications easier.

After evaluating AJAX and OpenLaszlo for a while we have finally chosen Flash, in particular Flex 2 and ActionScript 3 as the primary foundation for the client-side API of TopBraid Live. In our experience, Flex is the best available technology that is widely deployed and comes with all the flexibility that one would expect for true Rich Internet Applications. In particular we appreciate the nice object-oriented model and strong typing that makes ActionScript 3 code as maintainable as Java or C# code - unlike JavaScript with all its browser incompatibilities and ad-hoc constructs.

In August 2007 we announced the first comprehensive Semantic Web API for Flash. The TopBraid Live API provides a comparable data model to Java libraries such as Jena and Sesame. The triples and nodes in the data model are automatically synchronized with the server in a highly scalable architecture. Data is loaded as the user browses through the Semantic Web model, and triples and nodes are cached on the client, avoiding to continuously reloading everything. We provide some abstraction layers to run queries to back user interface components. Many UI widgets such as trees, tables, forms and graphical browsers come out-of-the-box as part of TopBraid Live.

The screenshot below shows TopBraid Ensemble, a multi-user Semantic Web browser and editor/wiki based on TopBraid Live:


In order to use TopBraid Ensemble, you need a TopBraid Live server to manage your RDF/OWL data stores (in whatever format you chose). You can configure which models are visible (and editable) by which users. The users can then log in and either navigate through the model or edit parts of it. The tool also provides search capabilities and even a graphical browser.

I believe that these capabilities and the smooth integration with TopBraid Composer as a professional development tool will make TopBraid Live one of the primary Rich Semantic Web Application platforms on the market.

It is ironic, but perhaps not unexpected, that many organizations who want the benefits of using an Agile approach to deliver software use a waterfall approach to adopting Agile practices: they form plans, they set milestones, and they measure progress by how many teams they have engaged. Old habits die hard, but like most waterfall software projects, most waterfall-style Agile adoption efforts fail to produce the results desired. The problem is that to get the results they want, they have to ch...
Organizations planning enterprise data center consolidation and modernization projects are faced with a challenging, costly reality. Requirements to deploy modern, cloud-native applications simultaneously with traditional client/server applications are almost impossible to achieve with hardware-centric enterprise infrastructure. Compute and network infrastructure are fast moving down a software-defined path, but storage has been a laggard. Until now.
Without a clear strategy for cost control and an architecture designed with cloud services in mind, costs and operational performance can quickly get out of control. To avoid multiple architectural redesigns requires extensive thought and planning. Boundary (now part of BMC) launched a new public-facing multi-tenant high resolution monitoring service on Amazon AWS two years ago, facing challenges and learning best practices in the early days of the new service.
HyperConvergence came to market with the objective of being simple, flexible and to help drive down operating expenses. It reduced the footprint by bundling the compute/storage/network into one box. This brought a new set of challenges as the HyperConverged vendors are very focused on their own proprietary building blocks. If you want to scale in a certain way, let's say you identified a need for more storage and want to add a device that is not sold by the HyperConverged vendor, forget about it...

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...
