Overview¶

This service communicates between the Search Database and the User Interface to allow structured search of databases, tables, columns, users, identifiers, views, semantic concepts & units of measurements used in databases.

Built-in search — Figure 1: Faceted browsing

Index¶

There is only one index database that holds all the metadata information which is mirrored from the Metadata Database.

Faceted Browsing¶

This service enables the frontend to search the database index with eight different types of desired results (database, table, column, view, identifier, user, concept, unit) and their facets.

For example, the User Interface allows for the search of databases that contain a certain semantic concept (provided as URI, e.g. temperature http://www.wikidata.org/entity/Q11466) and unit of measurement (provided as URI, e.g. degree Celsius http://www.ontology-of-units-of-measure.org/resource/om-2/degreeCelsius).

An example on faceted browsing is found in the usage examples.
