It can be seen as a webversion crossover of StreetComplete and MapContrib. It tries to be just as easy to use as StreetComplete, but it allows to focus on one single theme per instance (e.g. nature, bicycle infrastructure, ...)
The basic functionality is to download some map features from Overpass and then ask certain questions. An answer is sent back to directly to OpenStreetMap.
Furthermore, it shows images present in the `image` tag or, if a `wikidata` or `wikimedia_commons`-tag is present, it follows those to get these images too.
An explicit non-goal of MapComplete is to modify geometries of ways. Although adding a point to a way or splitting a way in two parts might be added one day.

1. The user clicks that big tempting button 'login' in order to answer questions - there's enough of these login buttons... The user creates an account.
* Note that _all messages_ must be read before being able to add a point.
* In other words, sending a message to a misbehaving MapComplete user acts as having a **zero-day-block**. This is added deliberately to make sure new users _have_ to read feedback from the community.
4. At 50 changesets, the [personal layout](https://pietervdvn.github.io/MapComplete/personal.html) is advertised. The personal theme is a theme where contributors can pick layers from all the offical themes. Note that the personal theme is always available.
5. At 200 changesets, the tags become visible when answering questions and when adding a new point from a preset. This is to give more control to power users and to teach new users the tagging scheme
7. At 500 changesets, I expect contributors to be power users and to be comfortable with tagging scheme and such. The custom theme generator is unlocked.
I love it to see where the project ends up. You are free to reuse the software (under GPL) but, when you have made your own change and are using it, I would like to know about it. Drop me a line, give a pingback in the issues,...
4. Run `npm run start` to host a local testversion at http://localhost:1234/index.html
5. By default, the 'bookcases'-theme is loaded. In order to load another theme, use `layout=themename` or `userlayout=true#<layout configuration>`. Note that the custom URLs (e.g. `bookcases.html`, `aed.html`, ...) _don't_ exist on the development version. (These are automatically generated from a template on the server).
1. Modify `"language"` to contain the new language, e.g. `"language": "nl"` becomes `"language": ["nl", "en"]`
2. Add extra strings to the texts. If it used to be a single-language theme, one can replace the strings, e.g.: `"description": "Welcome to Open Bookcase Map"` to `"description": {"en": "Welcome to Open Bookcase Map", "nl": "Welkom bij de OpenBoekenruilkastenKaart", "fr": "Bienvenue sûr la carte des petites bibliotheques"}`. If the correct language is not found, it'll fallback to another supported language.
3. If you notice missing translations in the core of MapComplete, fork this project, open [the file containing all translations](https://github.com/pietervdvn/MapComplete/blob/master/assets/translations.json), add add a language string there
The website is purely static. This means that there is no database here, nor one is needed as all the data is kept in OpenStreetMap, Wikimedia (for images), Imgur. Settings are saved in the preferences-space of the OSM-website, amended by some local-storage if the user is not logged-in.
When viewing, the data is loaded from overpass. The data is then converted (in the browser) to geojson, which is rendered by Leaflet.
When a map feature is clicked, a popup shows the information, images and questions that are relevant for that object.
The answers given by the user are sent (after a few seconds) to OpenStreetMap directly - if the user is logged in. If not logged in, the user is prompted to do so.
The UI-event-source is a class where the entire system is built upon, it acts as an observable object: another object can register for changes to update when needed.
The idea is that once in a while, the images are transfered to wikipedia or that we hook up wikimedia directly (but I need some help in getting their API working).
### Uploading changes
In order to avoid lots of small changesets, a changeset is opened and kept open. The changeset number is saved into the users preferences on OSM.
Whenever a change is made -even adding a single tag - the change is uploaded into this changeset. If that fails, the changeset is probably closed and we open a new changeset.
