Filter: Allow to filter by key/value search term

[tordans]

This is a feature request.

UseCase

I would like to monitor a larger area like whole Berlin for everything that has to do with bike-infrastructure.

Right now, I can create a filter for all changes for Berlin. And subscribe to this via RSS.

But I cannot filter this based on the OSM tags that where used in the changesets.

Idea

Add one or two fields to the filter view:

Filter to changesets that use this keyword inside one of the changesets OSM keys:
[_____] (enter keywords separated by comma)

Filter to changesets that use this keyword inside one of the changesets OSM key-values:
[_____] (enter keywords separated by comma)

Example 1:

I filter for key-keyword cycle to find changesets that use keys like cycleway or bicycle. (OSM Wiki)

Example 2:

I filter for "key value"-keyword bicycle to find changesets that use keys like amenity=bicycle_parking, amenity=bicycle_rental or shop=bicycle. (OSM Wiki)

I want to check bicycle, hiking… routes.

Sometime I want to check one specific route (see #469), but sometime I want to check i.e. all relations with type=route and/or route=bicycle.

Add one or two fields to the filter view:

I suggest to add a field that accept and evaluate simples expressions i.e like Overpass Wizard Queries.
See Tag Searches, Boolean Operators and Meta-Data Filters.

• Search by key : emergency=* (or simpler emergency ?)
• Search by tag : highway=cycleway
• Search by metadata : type:relation and id:4840541
• Boolean search: highway=bus_stop or railway=platform

After learning more about osmcha at SOTM Heidelberg, my understanding is now, that those filters are a problem to build since the required data is missing. The UI only knows about the changeset at first and about actual changes/tags only after the user choose a result. It might be possible to extend the osmcha-changeset data or build a different filter+list UI based on overpass data.

Do you talk about Using OSMCha to understand bad edits?
Unfortunately this talk wasn't recorded.

Yes, the UI probably know nothing about changesets content.
It need also changes in OsmCha backend.
