Definition
The action of composing a set of criteria for locating information.
The procedure to search an archive based on specific search criteria (search) and to obtain information on available products (discovery). Data search and discovery are enabled by generating and maintaining searchable metadata and browse image catalogues, as well as providing a catalogue service for making the catalogue accessible (e.g. OGC CSW) and mechanisms to retrieve and present the information contained in the catalogue, e.g. via the graphic user interface of a data portal.
During the discovery following a data search the user finds data based on his search criteria and evaluates if the data found are suitable for his application ('fit for purpose') by e.g. viewing the browse image, evaluating metadata such as coverage, quality information, or cost and licensing conditions. He may then decide to retrieve the data.
Search and discovery as well as retrieval are components of data access.
