# OSM Data Model

The OSM Data Model determines how our data is structured in the OSM database.

In general it is working well for us, but it has its problems. We have changed

it in the past and we can change it again, if we find better ways of doing

things.

This repository documents what we have and where problems are and here

discussions can take place to see how we can evolve the data model into

something better suited for the future of OSM.

## History

At the [State of the Map](https://2018.stateofthemap.org/) conference there

was a talk ["Modding the OSM Data

Model"](https://2018.stateofthemap.org/2018/T107-Modding_the_OSM_Data_Model/)

by Jochen Topf about this subject

([slides](https://media.jochentopf.com/media/2018-07-30-talk-sotm2018-data-model-en-slides.pdf),

[video](https://youtu.be/hUkE_fHEoZ8?t=9480)). After that we had a workshop

["Areas, Routing, and Diffs: Can we have Something Better than

Relations?"](https://2018.stateofthemap.org/2018/W019-Areas__Routing__and_Diffs__Can_we_have_Something_Better_than_Relations_/)

by Roland Olbricht, which was also about this subject (sorry, no video).

At the FOSSGIS2018 we had a discussion on some of this already. A video [is

available](https://media.ccc.de/v/2018-5412-evolution_des_openstreetmap-datenmodells)

(in German).

In spring 2022 the

[EWG](https://wiki.osmfoundation.org/wiki/Engineering_Working_Group)

[commissioned a

study](https://blog.openstreetmap.org/2022/06/02/announcement-data-model-study/)

about the state of affairs and possible next steps. The results were

presented at [SotM 2022](https://2022.stateofthemap.org/sessions/W3AGY8/).

## Tools

To find the best new data model we need statistics. And we need tools to

convert from one format to another to analyze them. Some tools are available

from https://github.com/osmcode/osmium-surplus.
