D-Net

Log when the resource could not be registered in the catalogue and hence we get a blank uuid

Loggin queries that returned 504 GatewayTimeout

ENsure that also resource names are compliant to the rules of the catalogue

based on the sparql templates competency is a string, in the model it is a PE36_Competency_Type

Let\s check if we do not get the following warning at client side by setting the response status in void GET methods that write directly on the output stream. The warning is: 'org.springframework.http.converter.json.MappingJackson2HttpMessageConverter- Failed to evaluate serialization for type [void]: java.lang.IllegalStateException: Failed to instantiate standard serializer (of type com.fasterxml.jackson.databind.ser.std.NullSerializer): Class com.fasterxml.jackson.databind.ser.BasicSerializerFactory can not access a member of class com.fasterxml.jackson.databind.ser.std.NullSerializer with modifiers "private"'

I do not want to register also the E55_Types

better error logging

ignore integration test

Added crm:P2_has_type for all sparql query templates

Some vocabulary codes changed, updating the cleaner rule accordingly
