Jos van den Oever wrote for his personal use the JStreams classes that allow one to easily read nested files. JStreams have proven very fast and have been included in the clucene c++ search engine. These classes would also be a cool extension to the KIO plugins for allowing the user to browse e.g. files in a zip file that is stored in an email attachment. Another use would be to write a crawler that
can gather information from all files in the filesystem even if they are hidden in emails or archives.
Jos intended to add this feature to Kat, but because of the slowdown in the Kat project and the great problems of the latest version, he developed a small daemon that can index information using the JStreams crawler. This small program grew up and became Strigi.
Jos named the program Strigi, which is short for Strigiformes.
