The focus of this paper is on the design, implementation, and validation of asynchronous multimedia annotations designed for Web-based collaboration in educational and research settings. The two key questions we explore in this paper are: How useful are such annotations and what purpose do annotations serve? What is the ease of use of our specific implementation of annotations? The context of our project has been in the area of multimedia information usage and collaboration in the biological sciences. We have developed asynchronous annotations for HTML and image data. Our annotations can be executed via any browser and require no downloads. They are stored in a central database allowing search and asynchronous access by all registered users. An easy to use user interface allows users to add, view and search annotations. We also performed a usability study that showed that our implementation of text annotations to validate our implementation.
