Abstract: A system includes presentation of a visualization of a result set, the visualization including a plurality of graphical representations, each of the plurality of graphical representations associated with a respective data point comprising at least one dimension value and at least one measure of the result set, reception of a selection of a first data point of the plurality of data points, presentation of an interface to receive a one or more comments in response to selection of the first data point, reception of a first one or more comments, and storage, in response to reception of the first one or more comments, of an identifier of the first data point in association with the first one or more comments.

Abstract: A system includes reception of a first query, the first query comprising a meta-facet, determination of one or more dimensions associated with the meta-facet, determination of a dimension query for each of the one or more dimensions based on the first query, execution of each of the determined dimension queries to generate a respective result set for each of the determined dimension queries, and presentation of a respective visualization of each of the respective result sets.

Abstract: A method for querying an Open Data Protocol (“opendata”) opendata provider includes receiving a relational database query, parsing the relational database query, creating an execution plan, transmitting an opendata query to the opendata provider, transforming a response into a relational format, and providing the transformed response in reply to the relational database query. The method further includes mapping content of an opendata entity data model to a relational model catalog, and processing a portion of the execution plan by an opendata driver implemented at the server. The method can further include the server retrieving document metadata from the opendata provider, building an internal model of the document metadata, and responding to a metadata request. A system for implementing the method and a non-transitory computer readable medium are also disclosed.
