We have created a number of Web-based services, here are some of them.
The implementation of GooDiff is available as free and open source software. You can download GooDiff and follow its development on GitHub, where the software is separated into its back-end and frontend components.
FreeArchive is a service for archiving online information that is driven by end users. Here, everyone becomes the archivist. The process of archiving is based on the voluntary act of tagging Web resources using machine tags and a specific FreeArchive namespace. The “preservation” of Web resources is performed by the server-side FreeArchive crawler component which automatically retrieves tagged resources from the World Wide Web. This allows users to save relevant information for the future, even when the original source becomes unavailable on the Web.
