Wow, three in a day! The ETTK team must be working overtime, because the Emerging Technologies Explorer, Semantic Tools for Web Services, and BeepLite Networking Layer all became ETTK technologies today.
The Emerging Technologies Explorer is great way to look at what's going on in the ETTK from within an Eclipse environment. You can use it to quickly learn about new technologies, see screenshots, or look at demos. You can even use it to install certain technologies directly into your Eclipse environment.
The Semantic Tools for Web Services introduces a way to automate the lookup of compatible web services. Sometimes, the answer you need is the composition of two web services. For example, suppose you want to know the population of the capital of Texas. You might be able to use two existing services: one that returns the capital city for a state and one that returns the population for a city. The semantics approach offers a way to do these types of searches.
The BeepLite Networking Layer was updated to Version 0.9.4 and joined the ETTK today. It's a Java implementation of BEEP (Blocks Extensible Exchange Protocol) and helps you more easily implement a secure, multi-channel, asynchronous set of network connections that adhere to standard protocols.
