Querying curated data resources requires that the request be brokered by the data publishing subsystem before any results will be retrieved from the data curation subsystem and delivered to the client from which the source came.

Notation of Computational Viewpoint Models#notation_cv_objects

 Any kind of CV Presentation Objects#virtual_laboratory is able to query the data held within a research infrastructure subject to access privileges governed by the  CV Service Objects#aaai_service (invoked via its authorise action interface). Data requests are forwarded to a CV Broker Objects#data_broker within the data publishing subsystem, which will interpret the request and contact any internal services needed to fulfil it. In this case, the data broker will invoke the CV Service Objects#catalogue_service via its query data interface; the catalogue service will locate the datasets needed to answer any given query and then proceed to query resources within infrastructure CV Component Objects#data_store_controller.
