he LUPOSDATE SPARQL system supports various approaches to manage RDF data and process SPARQL queries: Index, RDF3X, Stream, Jena and Sesame. Jena [21] and Sesame [3] refer to third-party SPARQL engines. Index is our in-memory Engine presented in [6]. Stream is our stream-based implementation (see [10]). RDF3X is a re-implementation of [14], but is further enhanced with additional optimization strategies.
Visualization and Interaction for Business and Entertainment
Our groups focuses primarily on topics in human-computer
interaction (HCI) and information visualization
Irientation describes the way in which a logical connection can be created and visualized between objects and object's states. Often used animations in this category are directional motions. They give an impression of the location and the structure of information. Orientation describes the object's environment and therefore the system's information architecture. For that reason, Orientation invites the user to explore the user interface.
LiveCode brings three key things to your development process: the interface, the language and live coding. You start with the interface. Get going by opening a new project and dragging items onto it. A button, a field, a scrollbar… whatever your app needs. Play about with them a bit. Resize, rearrange, change the color, add some pretty drop shadows. Make it look funky and just the way you want it.
Now the language comes in. It’s English. You add it to your objects to make them do what you want them to do. For example writing:
What is Lily?
Lily is a browser-based, visual programming environment that lets people create programs graphically, without writing code, by drawing connections between data, images, sounds, text and graphics. Lily's cross-platform, free, open source and is written in JavaScript. Did we mention it's fun? Download it, check out the demos or read more about
Waterbear is a toolkit for creating drag-and-drop programming languages, with some example languages you can play around with and learn from. The goal is to make it easy to wrap other existing languages with Waterbear blocks to create draggable, snappable syntaxes for them.
