Build and Install

Build and Install documentation for POI Data Provider can be found at the corresponding section of the Admin Manual.


The POI Data Provider is run as PHP scripts within a web service. It is enabled upon installation. The scripts are run upon external queries. No special action is needed for running.

API Overview

The POI Data Provider uses REST API. The structured POI data is presented in JSON format. E.g.:

  "fw_core": {
    "categories": ["cafe"], 
    "location": {
      "wgs84" { 
        "latitude": 65.059334, 
        "longitude": 25.4664775
    "name": {
      "__": "Aulakahvila"

The POIs are identified by UUIDs. E.g.:

  "462c375c-3284-4d80-a8a0-6c09608623a5": {
    "fw_core": {...}
  "5069d6b8-7ded-43c8-b71d-48aec9364ca9": {
    "fw_core": {...}
  "96f9d67e-9177-4d89-9bbb-e13f4cec7308": {
    "fw_core": {...}

Sample query:

GET http://{poi server}/radial_search?lat=65.059254&lon=25.470997&radius=250&category=cafe,restaurant&begin_time=2014-01-23T11:30&end_time=2014-01-23T13:00&min_minutes=30&max_results=2

This finds such cafes and restaurants within 250 m radius at center of Oulu, Finland that are open for at least 30 minutes within given time interval.

Available queries are

  • GET /get_components Provide the POI data components supported by this server
  • GET /poi_schema.json Provide the full JSON schema of the data supported by this server
  • GET /poi_categories.json Provide the POI categories supported by this server Version information
  • GET /radial_search Provide the POIs within given circle
  • GET /bbox_search Provide the POIs within given bounding box
  • GET /get_pois Provide the pois listed by the query
  • POST /add_poi Add a new POI to the database
  • POST /update_poi Update existing POI data
  • DELETE /delete_poi Delete existing POI from database

5.1 2015-12-29 Quality Boost

  • Mostly error corrections
  • NOTE: Two of interface changes are introduced:
    1. In internationalized texts the language key for the language-independent text is changed from "" (empty string) to "__" (two underscores). The reason is that MongoDB does not accept zero length keys. SQL script to update the database: install_scripts/update_fw_core_intl_to_5.1.sql
    2. Two resources are added to the interface to facilitate automatic configuring of POI-data editor/validator functionality in clients.
      • poi_schema.json - Full JSON schema of POI data supported by the server
      • poi_categories.json - Description of POI categories supported by the server
