Linguistic Tree Constructor
Syntax tree editor for rapid annotation of existing text
Linguistic Tree Constructor (LTC) is a tool for drawing lingusitic syntax trees of already-existing text. It is a syntax editor, not a text editor, so the text has to exist already. It is best suited for large-scale, rapid creation of hand-annotated treebanks. The user can define their own node categories, and can label each node with labels, also definable by the user. LTC supports "generic", X-Bar and RRG trees. Supports interlinear texts in SIL SFM format. -

geometry3d
A Python library for geometric objects in 3 dimentions
Implemented classes of 3d objects: * Vector * Point * Line * Plane * LineSegment Yet incompletely implemented classes: * Triangle * Disk (closed circle) * Union (a collection of 3d objects) Each object has methods for finding its sizes, containing box or containing sphere. It finds intersection and distance or closest to another object part of itself. It also can tell if it contains the other object or is it contained by that. Where appropriate, it's easy to check orthogonality and parallelism. Vectors are sub-typed from numpy ndarray class. Extensive unit tests are included. Test coverage exceeds 95%. See documentation of the library internals in section Files ( https://sourceforge.net/projects/geometry3d/files/ ). -

EMFTrace
Repository for dependencies between software design artefacts
EMFTrace extends the EMFStore repository by elicitating dependencies between related models of different modeling and programming languages. The explicit recording and modeling of different types of dependencies as traceability links shall support evolutionary changes by impact analysis, early evaluation of quality flaws, and better comprehension. It is an open source project to support the practical application of research results regarding development methods for evolution of software architectures and for software reengineering. EMFStore is used for integrating models and source code from different tools and vendors, while EMFTrace provides means for dependency detection, dependency visualization, and change impact analysis. -

Event-B Generic Instantiation
A Rodin Platform Plug-in for Generic Instantiation
Generic Instantiation tool is developed by HITACHI and ETHZ for Event-B as a Plug-in for RODIN platform. Main features of the tool are as follows: - Generic Instantiation Files for storing information about generic instantiation. - Wizard for creating generic instantiation files. - Editor for generic instantiation files. - Static checker for generic instantiation files. - Performing generic instantiation by creating a new project based on a source project and generic instantiation files. -
