    I am interested in documenting historic political incidents on a map - specifically terrorist attacks, bombing, political safehouses in southern africa during the liberation struggle.

    is OSM the best way to do this? can I create a 'political history layer'? or something similar? how long would it take me to get up to speed? and how would I go about learning how to do this?

    I'm a consumer of OSM data so have minimal expertise but, if you have some knowledge of creating webpages Leaflet.js might be worth a look:

    https://leafletjs.com/examples/quick-start/

    This way, you can overlay your own information onto OSM (or other basemaps) for display. No need to edit OSM directly.

    Nothing dynamic is required server-side. You can prepare your static data offline and upload to any web host. All rendering will happen in the browser.

    For your use case, a plugin to load KML or other GIS data formats instead of writing Javascript to populate your overlay will make your life easier:

    https://leafletjs.com/plugins.html#overlay-data-formats

    For instance you can use Google Earth to write a KML file then import it into your Leaflet map.

    If you need more control than Leaflet provides, then there is OpenLayers.

    Apologies! If you have the time to burn, then doing the quickstart example from the Leaflet page (first link) might make things clearer.

    You can write the necessary HTML page locally and load it in your browser; it'll still work (no hosting provider needed).

    Regarding Google Earth/KML, that's just an easier (point and click) method of creating a dataset to display in your map:

    The alternative is writing your geodata in a variety of arcane formats in a text editor.

    thank you. Hopefully I will find time to look into it. but I also need to crowdsource the data - receiving some interesting information, but only small amounts so far, so it may not be worth upskilling.
