[Fiware-fic3-coaching] Questions POI Data Provider

[Johnny Waterschoot]

Matthias,



I added the fiware-fic3-coaching at lists.fiware.org addres also, this creates
a ticket in the system that Franck and his colleagues use for support
tracking. .



Other sources to check are also https://ask.fiware.org/questions/ and the the
e-learning portal. <https://edu.fiware.org/course/view.php?id=96>

Dear Franck,



This is a kind reminder on my mail below, with some questions regarding the
POI Data Provider.



Thanks in advance,



Mathias

Dear Franck,



As indicated before by Frank Verbeeck, we started our analysis of the
FIWARE enablers in the context of our FIC3 project ‘QuAALity’ in
collaboration with Gociety, in order to be able to integrate them in the
Gociety architecture in a next step.



We started with the POI Data Provider GE, on which we have the following
questions:

   - The enabler uses two separate databases; a (structured) PostGIS
   database on the Generic POI server to do spatial search of location points,
   and a (unstructured) database (e.g., MongoDB) on the business-specific POI
   server to store extra business-specific POI info. As the choice for two
   databases means that you need to support two technologies, we were
   wondering about the rationale for this choice? MongoDB namely also provides
   geospatial query operators (using GeoJSON), and is thus similar in
   functionality as PostGIS (
   https://docs.mongodb.org/v3.0/reference/operator/query-geospatial/).
   Does PostGIS provide distinguishing features which could be interesting to
   explore in our context, e.g. the actual detection of POIs, faster lookups,
   ...?
   - The documentation of the POI Data Provider suggests to install the
   Pecl_HTTP module voor PHP 5. However, the most recent version of this
   module only runs with PHP7. We thus see two options: either upgrading to
   PHP7 (our preferred option), or install a lower version of the module
   (e.g., 2.1.1). Does a choice for one of these options impact the
   functionality of the enabler?
   - The file 'example_poi_2_fw_relationships.json’ in the
   'install_scripts/test_data/‘ folder is missing on the Git repository of the
   enabler, which results in an error. In the commit history, we found an
   earlier version of that file, with which we can successfully install the
   module, although we were wondering if any more recent updates/fixes to this
   file were made that were not recorded in the Git repository?

Thanks in advance for your feedback.



Best regards,



Mathias
