| - | Symbolic trajectories enable to attach semantic information to geometric trajectories . Essentially, symbolic trajectories are just time-dependent labels representing, for example, the names of roads traversed obtained by map matching, transportation modes, speed profile, cells of a cellular network, behaviors of animals, cinemas within 2km distance, and so forth. Symbolic trajectories can be combined with geometric trajectories to obtain annotated trajectories. | + | Symbolic trajectories enable to attach semantic information to geometric trajectories.

| The goal of this project is to explore how to implement symbolic trajectories in MobilityDB. This implementation will be based on the ttext (temporal text) data type implemented in MobilityDB and will explore how to extend it with regular expressions. This extension can be inspired from the [[https://www.postgresql.org/docs/13/functions-json.html|jsonb]] data type implemented in PostgreSQL. | The goal of this project is to explore how to implement symbolic trajectories in MobilityDB.
