    Linguistic Tree Constructor

    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.

    DAE Tools Project

    DAE Tools Project

    Object-oriented equation-based modelling and optimisation software

    DAE Tools is a cross-platform equation-based object-oriented modelling, simulation and optimisation software. It is not a modelling language nor a collection of numerical libraries but rather a higher level structure – an architectural design of interdependent software components providing an API for: - Model development/specification - Activities on developed models, such as simulation, optimisation, sensitivity analysis and parameter estimation - Processing of the results, such as plotting and exporting to various file formats - Report generation - Code generation, co-simulation and model exchange The following class of problems can be solved by DAE Tools: - Initial value problems of implicit form - Index-1 DAE systems - With lumped or distributed parameters - Steady-state or dynamic - Continuous with some elements of event-driven systems

    ConceptBase.cc

    ConceptBase.cc

    A Database System for Metamodeling and Method Engineering

    ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.

    PostgreSQL Database Modeler
    ** ATTENTION ** THIS PROJECT HAS MOVED TO: https://github.com/pgmodeler/pgmodeler New releases only will be available on GitHub. PostgreSQL Database Modeler, or simply pgModeler is an open source project of a CASE tool for modeling PostgreSQL that merges the classical concepts of modeling using entity-relationship diagrams with specific features that only PostgreSQL implements. The pgModeler translates the models created by the user to SQL code and apply them onto database clusters from version 8.0 to 9.1. Please, let me know how the pgModeler is working on your computer! Help to improve this project, give your feedback about the software or report any bug at "Tickets" page. Do not forget to detail the bug and if possible attach a screenshot or model database which expressed the bug. Follow the pgModeler profile on Facebook/Twitter and be up-to-date with new features, fixes and releases. https://www.facebook.com/pgmodeler https://twitter.com/pgmodeler
