[Geoprisma-users] datastore vs resource

[Steve.Toutant at inspq.qc.ca]

The confusion was that we only have wms service. So 1 datastore = 1 
resource. We have more than 200 layers...
The concept of a resource seems to be unnecessary to us...for the moment.
thanks everyone for your help
Steve

Re: [Geoprisma-users] datastore vs resource








Steve,

  If I may add: a DataStore is the equivalent of a mapfile layer, or a 
layer in any service config.  To retake Alexandre's example :

  [DATA] is a 'hospital' table from PostGIS

  [DATA] -> [MapServer WMS Service] -> served as a 'hospital' layer inside 
a mapfile, which becomes the [Hospital WMS DataSource] in GeoPrisma

  [DATA] -> [TinyOWS WFS Service] -> served as well as a 'hospital' layer 
inside the config.xml, which becomes the [Hospital WFS DataSource] in 
GeoPrisma

  Those 2 DataSource point to the same data in the back-end.  They are now 
grouped as a single entity called 'Resource' in GeoPrisma.  The 
authorization to read/write this data is then linked to the Resource, not 
the DataStore nor the Services.  That way, a single 'Read access to the 
Resource to a user' would allow all requests to the WMS service as well as 
GetFeature requests to the WFS one.

HTH,

Regards,

Alexandre

A ressource is a group of datastores that represent all the part of the 
data.
A data store is a part of the data linked to a service.
Exemple :

Say you want to show Hospitals on a map: 
You'll have a ressource for the hospitals with those datastore for exemple 
:
    - DS_hospital_WFS that link to your WFS server with the layer of the 
hospitals;
    - DS_hospital_WMS that link to your WMS server;
    - DS_hospital_HTTPRequest if you want to manage your data via http 
forms;
    - DS_hospital_Cache that will be linked to your MapCache server;

So a ressource is to define the content and the datastores are the way to 
connect with it.

Check the samples with the source code, there is a lot of the configs that 
are used there.

Hi, 
We are 3 here reading the doc and trying to understand the difference 
between a datastore and a resource. 
If someone could explain by an example it would be very appreciated 

many thanks
