Itzam/Sharp is a C# class library for creating and manipulating keyed-access database files containing variable-length, random access records. Information is referenced by a user-defined key value; indexes may be combined with or separate from data. Itzam/Sharp implements the Itzam engine (see Itzam/Core and Itzam/Java) in 100% managed C#. At 32K, the Itzam/Sharp engine is both small and powerful, and it works with any .NET language, including F# and Visual Basic.
Basenji is an indexing and search tool designed for easy and fast indexing of media collections. Once indexed, removable media such as CDs and USB sticks can be browsed and searched for specific files very quickly, without actually being connected to the computer. Besides file hierarchies and audio track listings, Basenji also presents extracted metadata (image dimensions, mp3 tags etc.) and content previews of indexed media in a clean and straightforward user interface.
AudioScout is a distributed audio content indexing system. It can index a large collection of audio content for the purpose of later recognition of unknown signals. Robust to noise, different encodings, and other types of distortion, it can be used for a variety of applications including duplicate detection of files, identifying music, as well as more sophisticated uses involving the enforcement of copyrights and ensuring lawful use of content.
Yioop! is a PHP search engine. Yioop! can be configured as either a general purpose search engine for the whole Web or it can be configured to provide search results for a set of URLs or domains. Yioop can crawl pages or can directly index archives such as ARC and WARC. It supports indexing several file formats such as HTML, Atom, PDF, DOC, PPT, RTF, RSS, XML, SVG, PNG, JPG, BMP, GIF, and sitemaps. The Yioop! crawler can be deployed on one or many machines. It supports having one or more to crawl scheduler processes, as well as multiple fetchers and mirrors. Crawling respects robots.txt including Crawl-delay. Yioop! crawls are stored in a Web archive format that is easy to move around. Crawling can be done on one machine and the results deployed elsewhere. Yioop! supports mixing of crawls. Yioop! comes with a search front end that can be localized as desired using a GUI. This GUI supports RTL languages. Management of crawls can also be done using this GUI. Yioop! can be configured in a straightforward manner to make use of file caching or memcache if available.
