Versal is an open publishing platform designed to transform online learning from passive presentations into interactive online educational experiences, without requiring coding experience. Using the Versal platform, teachers and subject matter experts can share their knowledge using a creation canvas, gadget architecture, open APIs, and flexible embedding options. Versal provides a simple iframe/postMessage-based API for building interactive learning applications which are called gadgets. Developers use HTML5/JS/CSS to create gadgets which are then hosted on the platform and configured by teachers for learners to interact with. The set of services include persistence, asset uploading/transcoding, and assessment.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
