Layer meta data

Basic layer meta data is of the technical data structure and properties for Layer discoverability.

In addition, a set of meta data properties describes the RSDB layer in more detail. A custom properties set can be defined for the RSDB. If no properties set is provided Dublin Core properties set is used.

At the RSDB web interface, layers details page, the Info section shows current descriptive meta data. On the edit dialogue information can be it can be entered for that RSDB layer. With the ADD FIELD-button more properties can be added. The list of available properties corresponds to the custom properties set.

The RSDB distribution package contains the custom properties set definition file for Dublin Core meta_data_schema_dublin_core.csv. It may serve as a starting point for the creation of other custom properties set definitions:

name,fixed,description
creator,,"An entity responsible for making the resource." 
date,,"A point or period of time associated with an event in the lifecycle of the resource."
rights,,"Information about rights held in and over the resource."

In the RSDB config file config.yaml the custom properties set definition file is specified thogether with a description which is shown in the RSDB info edit dialogue from above:

server:
  meta_data_schema_file: 'meta_data_schema_dublin_core.csv'
  meta_data_schema_description: 'Fields conform to the Dublin Core metadata standard.'
