Abstract: A data visualization metrics explorer can be provided using JSON and hypertext. When an element of a grid row is selected, a new metrics explorer blade can be opened. A filter can be applied so that only information associated with the selected element is presented. Additional filters may also be applied to the data that is displayed. Progressive, iterative filtering can occur. The links between blades can be specified using JSON and hypertext. Multi-linking and re-use of individual JSON files can be performed by linking the JSON files together into a web. The web of visualization can be used to construct a web of visualization actions enabling data visualization exploration.

Abstract: A computer-implemented method for detecting test similarity between first and second tests for a software system. The computer-implemented method includes receiving data indicative of respective method call sequences executed during each of the first and second tests, generating, with a processor, a similarity score for the first and second tests based on a comparison of the respective method call sequences, and providing, via a user interface, a result of the comparison based on the similarity score.

Abstract: Use of declarative constraints in an error validation framework of a graphical modeling tool. The declarative constraints define one or more rules that objects of a graphical model should adhere to. When enforced against the graphical model, objects that do not conform to the rules may be identified. A declarative relationship between the non-conforming object and its visual representation in a graphical diagram may be used to allow for visually identifying the visual representation in the graphical diagram.

Abstract: A data structure and application programming interface for creating and manipulating object model artifacts within a meta-model is provided. The data structure may include higher level abstractions of the type system to provide a set of services to implement software design tools and editors.
