MobilityAPI-Python: OGC API – Moving Features server over MobilityDB
A PyMEOS-backed Python implementation of OGC API – Moving Features (OGC 22-003r3) over MobilityDB. The HTTP server exposes collections and moving features with the full read/write lifecycle (GET/POST/PUT/DELETE), the temporal-geometry sequence, the derived temporal-geometry queries (distance, velocity, acceleration), and temporal properties; a bulk-ingest extension appends a GeoJSON/GeoParquet fleet feed as instants. PyMEOS performs the temporal-data conversion (MF-JSON in and out), so the server holds the OGC request/response shaping and the database holds the temporal computation. The repository carries a notebook tutorial over Danish AIS data, unit tests, and the PostgreSQL License. The compiled Go server at MobilityDB/MobilityAPI is the reference (production) implementation.

MobilityAPI is the result of contributions from several individuals across two phases. The project's lineage starts with **pg_mfserv** (2024), an OGC API – Moving Features prototype that established the Python-server skeleton and the PyMEOS-based MobilityDB integration pattern. **MobilityAPI** (2025–) extends that foundation into a production-grade implementation with a structured resource layout, comprehensive tests, and OGC conformance.
4+
5+
## Founding phase (2024) — as `pg_mfserv`
6+
7+
Affiliated with [Université libre de Bruxelles (ULB)](https://www.ulb.be/).
8+
9+
- **Maxime Schoemans** ([@mschoema](https://github.com/mschoema)) — initial commit, OGC API – Moving Features endpoint design, project skeleton.
10+
- **Victor Morabito** ([@MrMaxime1er](https://github.com/MrMaxime1er)) — main developer of pg_mfserv: column discovery, request/response handling, exception handling, route refactors, feature endpoints (collections, items, temporal geometry, temporal properties).
11+
12+
The pg_mfserv repository is preserved at [`MobilityDB/pg_mfserv`](https://github.com/MobilityDB/pg_mfserv) in archived form.
13+
14+
## Current phase (2025–) — as `MobilityAPI`
15+
16+
Affiliated with [Université libre de Bruxelles (ULB)](https://www.ulb.be/).
17+
18+
- **Sirine Meraoui** ([@sirimeraoui](https://github.com/sirimeraoui)) — current maintainer; structured resource layout (`resource/` tree); test infrastructure; OGC conformance; HTTP-status-code translation; documentation; demo notebooks; AIS dataset integration.
19+
20+
## Acknowledgements
21+
22+
The project benefits from the broader [MEOS ecosystem](https://libmeos.org/), in particular:
23+
24+
- **[PyMEOS](https://github.com/MobilityDB/PyMEOS)** — the Python binding of MEOS that MobilityAPI consumes today.
25+
- **[MobilityDB](https://github.com/MobilityDB/MobilityDB)** — the PostgreSQL extension providing the SQL surface backing MobilityAPI.
26+
- **[OGC API – Moving Features Standard](https://docs.ogc.org/is/22-003r3/22-003r3.html)** — the standard MobilityAPI implements.
