h1. About WFS App Schema for BoreholeView

https://epos.brgm-rec.fr/geoserver/ows?service=wfs&version=2.0.0&request=GetFeature&TYPENAMES=gsmlp:BoreholeView&OUTPUTFORMAT=text/xml;%20subtype=gml/3.2&count=1&resolveDepth=*

h2. # Trusted environment

This app schema has been successfully set up with those versions of GeoServer:

- BRGM ressource-rec: GeoServer 2.8.0

- BRGM epos-rec: GeoServer 2.9.2

h2. # Link to resources

Several content are offered in https://forge.brgm.fr/svnrepository/epos/trunk/tools/geoserver/

h1. # Tips for configuration of App-schema

h2. ## workspace

The content of workspaces (the gsmlp folder) should be put in your geoserver/data/workspaces.

h2. ## DB part (for xsd version 1.0.0)

App schema provided in SVN is actually set up for one table called "borehole_eu" with those columns:

 CREATE TABLE epos.borehole_eu

(

  boreholeid character varying NOT NULL,

  gmlidentifier character varying,

  name character varying,

)

h2. ## app-schema.properties

The datastore part from gsmlp_BoreholeView.xml is linked to a app-schema.properties file.

This file actually indicate how app-schema should connect to your database.

It should be put in geoserver/WEB-INF/classes.

h2. ## GML namespace and workspace

If GML namespace is not appearing in your BoreholeView response(replaced by null, e.g. null:name).

- Check in your GeoServer that gml namespace and workspace are properly set and attached to GML v3.2.

- Check in your "BoreholeView.xml" mapping that reference to GML is also pointing v3.2.

h1. About WMS for BoreholeView

* Creation of a table epos.borehole_sld for translating the SLD rules (from https://forge.brgm.fr/svnrepository/epos/trunk/sld/): this operation is not automatic... (see function epos.insert_borehole_sld())

<pre>

CREATE TABLE epos.borehole_sld

(

  pk_rule serial NOT NULL,

  name character varying(500),

  filtre_purpose_href character varying(500),

  filtre_length_greater integer,

  filter_length_lessequal integer,

  style1_symbol character varying(100),

  style1_size numeric,

  style1_color character varying(11),

  style2_symbol character varying(100),

  style2_size numeric,

  style2_color character(11),

  CONSTRAINT sldpk PRIMARY KEY (pk_rule)

)

</pre>

* if the SLD is updated, the table has to be updated as well. The best to do so is to update *the function epos.insert_borehole_sld()* which contains everything to create the SLD table. THen to refresh the materialized view.

<pre>

-- select * from epos.insert_borehole_sld();

-- REFRESH MATERIALIZED VIEW  epos.borehole_eu_06_sld;

</pre>

* Creation of a materialized view borehole_eu_06_sld joining the data and SLD rules. The Mapfile does only contain one Style (CLASS) rule, using the values from the database (performaces are better that way).

<pre>

CREATE MATERIALIZED VIEW epos.borehole_eu_06_sld AS 

 SELECT borehole_eu_06.location_wgs84::geometry(Point,4326) AS geom,

    borehole_eu_06.boreholeid,
