jOWL is a jQuery plugin for navigating and visualising OWL-RDFS documents. The small Demo on this page loads the prototypical wine ontology (cfr. OWL language guide).
...But what about the headers the browser sends?
The size of headers in a basic XHR request:
Firefox3: 495 bytes
IE7: 289 bytes
Safari: 357 bytes
That means if your little ajax request is simply sending 5 bytes, you’re still going to send a few hundred bytes. Wasting time, bandwidth, and processing. For XHR requests, you often simply do not need half of those headers. I already know what the user-agent is, and can send it at the start of the comms if needed. I don’t need an Accept header, because it’s irrelevant. The XHR is going to send back text. etc
We can do a little bit better… Here are the numbers when we add a few lines of js to cut down headers.
Earlier this week I presented at SWIG-UK about rdfQuery. rdfQuery is a set of plugins that I’ve developed for jQuery in order to support RDFa parsing, querying and generation. There are a bunch of other Javascript libraries for RDFa around, such as Mark Birbeck’s Ubiquity RDFa and Ben Adida’s RDFa library. What I’ve really tried to do with rdfQuery is tie it in with the “Write Less, Do More” philosophy of jQuery and provide a neat, elegant API. At least that’s the aim!
So what does it do? Well, I’ve just added the demo that I used on Tuesday into the repository, so if you grab hold of that you can take a look.
With Jaxer you can use your existing JavaScript and Ajax skills to create entire front-to-back
applications, or optimized presentation tiers that complement other back-ends.
HTML, JavaScript, and CSS are native to Jaxer, as are XMLHttpRequests, JSON,
DOM scripting, etc.
And as a server it offers access to databases, files, and networking, as well as logging,
process management, scalability, security, integration APIs, and extensibility.
Creating an Autocomplete Text Field Using the Eclipse Web Tools Platform
Forms needs a solid visual structure, a profound hierarchy of form elements (Fields and Labels), powerful techniques and Functionality (AJAX) to make the form look and work creatively. There is a great bunch of creative, outstanding and individually designed from scratch forms.
Thanks to AJAX, we can provide real-time feedback to our users using server-side validation scripts and eliminate the need for redundant validation functions and processing data.
Let’s take a look, hopefully you’ll find new ideas you can develop further on your own.
Put an open map widget in any web page
href value into a complete URI. I needed this because I wanted it to support stylesheets inside IE conditional comments, but of course to Firefox these are just comments — I had to parse each comment node with a regular expression to extract what’s inside it, and therefore, the href value I got back was always just a string, not a property or a qualified path.Ext JS is an excellent framework for building web applications that have desktop like functionality in a web browser. But what if you could take your JavaScript powered application and run on the desktop like any other native application?
The launch of Adobe AIR (formerly Apollo) has made this not only a reality, but extremely easy. Armed with early access Ext 2.0, Aptana IDE and a 4 pack of Red Bull I set out to build my first AIR application.
