Metadata

Geographical ressources (GeoJSON data) on cartostation are represented by metadata instances.

To make a resssource available in the Studio application, it has to be represented by a metadata instance.

The model in use is compliant with the European INSPIRE directive.

Add metadata

All metadata fields are described below.

Title

Set up a title for your ressource.

This field can be edited in the Metadata application.

Abstract

Set up an abstract for your ressource.

This field can be edited in the Metadata application.

External link

Set up a link to the external ressource (optional).

This field can be edited in the Metadata application

Ressource identifier

Ressource identifier is structured like a URL.

It is templatized as : loader://path

It is an internal identifier which is converted into a proper URL pointing to the ressource by the loader itself (eg: postgis loader).

ex :

• postgis : postgis://schema/table_name
• angled : angled://UI_code_name/query_ID where UI_code_name can be point, line or polygon

nb1 : you can point to distant ressources : for an accesible GeoJSON in EPSG:31370 ressource, an absolute URL will do the job.

nb2 : To delete a metadata, you will be asked to delete all the objects dependant on it. (Layers in maps etc..)

Geometry type

Select the geometry type of your ressource.

Bounding box

Has to be 0.0, 0.0, 0.0, 0.0 for now. It will be removed soon.

Point of contact

Point of contact for this ressource.

A point of contact is a user connected to an organization.

Create a centroid layer

Note : Works only for a polygon layer frome a query created via the Query application

• Duplicate a query (polygon only) metadata sheet
• Adjust metadata title accordingly
• Add /centroid at the end of its Resource identifier (eg : angled://l/45/polygon -> angled://l/45/polygon/centroid)
• Change geometry type for Point

Manage Metadata

Large amounts of matadata require maintenance. The advanced search function allows to filter the metadata by date, and also by count (how many map layers are actually using the table associated to the metadata).

Metadata can be deleted, and will not appear anymore.
