An '''automatic process''' gathers or "harvests" these documents from each data provider, and '''ingests''' them into a '''database''' where they are stored alongside those from other data providers. Data providers have control over their publishing tool via an '''admin interface'''.
 A '''web service''' carries out searches of this '''database''' in response to search requests received from a '''search interface''', possibly hosted by a third party as part of a '''web portal'''. The web service returns results back to the search interface, for presentation by the search inteface to display to the '''user'''. '''Search tools''' included in the search interface help the user construct search requests based on time periods, geographic areas and text terms from '''standard vocabularies''', provided by a '''vocab server'''.
