[OSM-dev] tagtransform for OSM - An effort make tagging and using OSM data easier; bridging different worlds together

Fri Dec 6 14:08:37 UTC 2019

Hi,

Sorry for my, probably stupid, questions.

1.  Is all this written in java?

2.  Is there anything going on in Haskell? I’d love to be involved in something using Haskell.

Thanks for your answer.

Using my specification which needs to be extended to create conpactibility among different formats while ensuring that my spec can be used on its own.

Different tagging schemes have emerged since the existence of OpenStreetMap, same are existing in parallel and a newer one deprecated an old one. Data customers without knowing the OSM community much get lost. This project aims to help developers who want to take advantage of the OpenStreetMap great database which is by the way a brilliant project. This project can also help to make tagging in OSM more orthogonal and more hassle free.

The community might need another tagging scheme than a renderer. I thought how we can resolve this, how we can get all sites on "one table" and that is the idea I had come up with:

>> The project bridges different worlds and is therefore a bridge. As bridge this project should not just connect different worlds together and by ensuring peace between those but also support exchange between those to develop a social economy of  "send and receive" This project should support the "come together" of (OSM) developers and mappers.
