Monotone browser (mtn-browse) is an application for browsing Monotone VCS databases without the need of a workspace. The interface allows one to easily select a revision from within a branch, find a revision using complex queries, navigate the contents of a revision using a built-in file manager, display file contents (either using the internal viewer or an external helper application), graph revision histories, compare the changes between different revisions or versions of a file (either using the internal difference viewer or an external application), find files within a revision based on detailed search criteria, display file annotations and easily refer back to the corresponding change documentation, and save files to disk.
Jumper provides an enterprise bookmarking engine for tagging and linking data objects. It lets you search and share high-value data across remote locations using tag metadata (expanded tag fields) to capture knowledge about data in remote data stores. It collects these tag profiles in a knowledge base where user-created tag profiles identify quality data resources, user-contributed tag information adds real-world knowledge about the data resources, and user-created reviews sort out the worthy resources from the inadequate. Other users can search for this data. In addition, they can directly contribute what they know about this data to the knowledge base. It allows the participants to act as a filter for what is valuable and build upon mainstream pursuits, but also uncovers valuable data hidden at the edge.
Jim (Java Image Manager) is a program for managing your personal images (photos, etc.). While Jim is really easy to use, its tagging technology is quite powerful. A plugin system makes it easy extensible with new technologies. It runs on several operating systems (including Windows, Linux and many more); all you need is a Java Runtime Environment.
smupcheck, which stands for Smart Update Checker, checks Web sites for updates automatically, even if they don't offer an RSS feed. It is a very basic tool, and does not offer advanced features such as checking password-protected Web sites, highlighting changes, or filtering results.
Nyagua is a little piece of software that may help you to manage your home aquarium. It can store data about measurements in aquariums and produce graphs from these. It can store data about expenses and produce a report with yearly, monthly, and daily costs. It reports the compatibility between fishes and plants in its database. It can import fishbase.org XML data, and your own pictures can be added.
Tagsistant is a semantic filesystem for Linux and BSD kernels. It uses directories as tags and allows file tagging by simply putting files inside desired tag directories. The path you are walking by is your query, e.g. tagsistant/tag1/AND/tag2/OR/tag3/AND/tag2/. Being a low level interface, a filesystem can be instantly used by shell users, file managers, or CGI. A plug-in architecture is under development to add autotagging functionality for common files like .mp3, .ogg, .jpeg, .html, and .xml. A transparent ontology engine is also under development to allow users create a relationship schema between directories.
