# Tracker Miners
Tracker is an efficient search engine and
[triplestore](https://en.wikipedia.org/wiki/Triplestore) for desktop, embedded
and mobile.
The Tracker project is divided into two main repositories:
* [Tracker SPARQL](https://gitlab.gnome.org/GNOME/tracker) contains the
triplestore database, provided as the `libtracker-sparql` library
and implemented using [SQLite](http://sqlite.org/). This repo also contains
the database ontologies and the commandline user interface (`tracker3`).
* [Tracker Miners](https://gitlab.gnome.org/GNOME/tracker-miners) contains
the indexer daemon (*tracker-miner-fs-3*) and tools to extract metadata
from many different filetypes.
