Photon/nominatim upgrade plan

[leonardehrenfried]

We need to get started with the nominatim and photon upgrades. I'm going to summarise the installation process here since there are quite a few steps required.

Nominatim

• Use standard nominatim 3.7
• Configure the the extra-tags import style with the following addition

{   "keys" : ["public_transport"],
    "values" : {
       "platform" : "main,fallback,with_name",
       "stop_position" : "main,fallback,with_name",
       "station" : "main,fallback,with_name"
    }
},

• Initial nominatim import
• Download https://data.mfdz.de/mfdz/nvbw_osm_matches.csv.gz
• Import CSV stop data with ./nominatim_add_ifopt.py -i osm-nvbw-stop-matches.csv (with invalidate)
• Nightly import run ./nominatim_add_ifopt.py osm-nvbw-stop-matches.csv (no invalidate!)

Photon

• use current komoot/master with two PRs merged in:
  • Experimental: simple synonym list komoot/photon#581
  • Rework location bias and query builder in general komoot/photon#580
• start up Photon with the flag -extra-tags ref:IFOPT
• run regular import
• start Photon with -synonym-file

Did I miss something?

The required IFOPT file is now: https://data.mfdz.de/mfdz/nvbw_osm_matches.csv.gz.

For the Photon can you currently please use #580 with #581 merged in instead of merging both to master. I did a couple of conflict-inducing changes on master which I'm in the process of resolving.
