Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for specifying a compound control. One of the methods includes identifying a first application. The method includes displaying a canvas. The method includes displaying, in the canvas, a first display object associated with the first application. The method includes identifying a second application, the second application being a computer executable program. The method includes displaying, in the user interface, a second display object associated with a second application. The method includes, in response to a user action that associates the second display object with the first display object, configuring the first application to invoke the second application. The method includes creating a third display object that includes the first set of selector objects and the second set of selector objects.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for metadata management. One of the methods includes receiving user input selecting a first node. The method includes receiving a first data lineage of a first object, the first object having a type, the first data lineage describing relationships between the first object and one or more datasets or transforms. The method includes receiving user input selecting a second node. The method includes receiving a second data lineage of a second object, the second object having the same type as the first object. The method includes performing a comparison of the first node and the first data lineage to the second node and the second data lineage. The method includes generating a report based on the comparison.

Abstract: Among other things, configuring an information collection/retrieval system includes receiving a data file structured to describe biological data, generating a first metadata representation of a first part of the data file, generating a first configuration file based on the first metadata representation; and configuring the information collection/retrieval system using the first configuration file.
