Developed in partnership with the National eResearch Collaboration Tools and Resources (NeCTAR) project, the SOAP-based Australian Synchrotron APIs are geared to let scientists access data on their experiments from Australia's Synchrotron, the nation's largest research facility, in a secure manner. This also permits data analysis through remote access.
POEditor's goal is simple: "A simple way to translate your software." POEditor accomplishes this task through a global community of translators who can work on needed translations or launch projects of their own. POEditor developed as a browser-based software localization tool. However, developers can now leverage the platform within existing sites and apps with the POEditor API. The API calls project related data and allows developers to track progress and users to work on projects.
Web APIs and mashups are not only of interest to the developer community. There are also research activities that look at how to improve various aspects of API design as well as services' and mashups' implementation and deployment. If you are interested in a cutting-edge research that may influence the future of Web APIs, then you should look at series of workshops on Web APIs and Service Mashups.
