Tracker (search software)

Tracker is a file indexing and search framework for Linux and other Unix-like systems. It is written in the C programming language.

Tracker has been adopted by the GNOME desktop environment and is heavily integrated into GNOME Shell and GNOME Files.

At its core, Tracker is a general-purpose SPARQL-based database; although it is developed together with the file indexer component, it may be used to store or access any kind of data that follows the RDF data model (such as querying Wikidata).

One of the developers of the Conduit application has suggested using Tracker to create "a metadata-enabled GNOME", similar to using Strigi as an indexer for a metadata framework in KDE Software Compilation 4.
