Hi Boris, a provider does not send queries (e.g. browse, read, write, create, delete, metadata) to nodes in the Data Layer. But the provider knows the data it providers in the Data Layer, since it has to know the answer to these queries. In general you always have one provider for a specific path in the Data Layer, this provider has to keep the data for every node he is responsible for. On the other hand you can have many different Clients which can consume this data, the provider makes available. Best regards, Nick
