Korallenriff is a program that collects input from different network sources and stores their data into one database. For example, it can receive POP3 mail or can fetch NNTP groups and store the received messages in a database. One can then, for example, use the database data within a Web site to display the latest postings of a newsgroup or to create an online mailing list archive. Another possible use would be to build a blogging-software where one can post via email.
Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
Vidrate is a tool for allowing multiple people to vote which video files of a database should be kept. This tool can help you to quickly free some space on your file server without specifically asking all the server's users which movies should be kept. The interface also allows you to mark videos as seen and to assign comments. Included is a cron job that periodically scans the video directory for new or deleted videos and also deletes videos that have the required number of votes.
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.
movemetafs is a searchable filesystem metadata store for Linux that lets users tag local files (including image, video, audio, and text files) by simply moving the files to a special folder using any file manager. It also lets users find files by tags using a boolean search query. The original files (and their names) are kept intact. movemetafs doesn't have its own user interface, but it is usable with any file manager.
Search::Xapian is a Perl XS frontend to the Xapian C++ search library. It is a fairly complete wrapper: most features of the Xapian library are made available for use from Perl. Xapian is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model as well as a rich set of boolean query operators. It's fast and scalable to hundreds of millions of documents.
Contractor Software allows contractors to manage their projects and interact with customers online. A contractor can post each task of a project. Each task has a start date and estimated completion date. The client can then always know where the project is and leave comments for the contractor on each task. The contractor can also reply to the client with a follow up comment. This enhances communication and also leaves a record for reference later.
Twibright Twig is a static HTML photo gallery software that supports organization of JPEG and PNG images into a directory structure and EXIF and JPEG comments. It is meant for more experienced users rather than newbies. Three levels of downscaled image and three levels of thumbnails are generated. Each image is assigned a unique identifier to faciliate easy random linking from a master Web site. It handles reasonable large galleries (and is currently used for a 3GB one). Automatic regeneration of added, changed, and deleted images can be done with one script.
