3. READ Project: EVP in Context • Requirements Engineering Assistance Diagnostic Project • READ Project's aim • Automatically generate a graphical representation of a requirements text in the form of a UML model and its XML representation • Accomplished by applying Natural Language Processing (NLP) techniques within the context of a Requirements Engineering process • Static and dynamic models are generated from the requirements text and stored as XML files. • The purpose of the EVP is to read these XML files and perform the visualization in the form of class and use case diagrams respectively.

4. READ Project : EVP in Context

5. READ Project : Methodology • Based on the work of Shadi Moradi Seresht • Four steps from ROM to static and dynamic models • 1. First-Cut Structural View • Extract a list of candidate classes, attributes, and relationships from the ROM presentation. • Flexible rules are used to extract this information. • 2. Expert-Comparable Contextual (ECC) Model • Comprehensive model that is domain specific • 3. Improved Structural View • A more comprehensive domain view based on the first-cut structural view and ECC model. • 4. Behavioral View • Dynamic view of the system extracted from the ROM presentation.

6. EVP : Requirements • Essential Functionality • Visualizing static model as UML class diagram • Visualizing dynamic model as UML use case diagram • Extended Functionality • Generating and visualizing First-Cut Structural View from ROM presentation • Generating and visualizing Improved Structural View from ROM presentation and ECC Model • Generating and visualizing Behavioral View from ROM presentation

7. EVP : Requirements • Non-Functional Requirements • Developing a commercial quality tool • Implications • Using existing frameworks • Using an existing code base • Acceptance Criteria • The EVP project will be accepted on the basis of meeting the criteria of its essential functionality. • Once the criteria of the essential functionality are met, if time permits, the EVP project will also include some or all of the criteria of the extended functionality.

8. EVP : Design • EVP leverages open source Eclipse frameworks and components • Eclipse Modeling Framework (EMF) • Modeling framework and code generation facility for building tools and other applications based on a structured data model • Graphical Editing Framework (GEF) • Allows developers to create a rich graphical editor from an existing application model • Graphical Modeling Framework (GMF) • Generative component and runtime infrastructure for developing graphical editors based on EMF and GEF. • UML2 component • Component of the Model Development Tools (MDT) project • Implementation of the UML 2.x OMG metamodel using the Eclipse Modeling Framework (EMF) • UML2 Tools project • Set of UML diagram editors developed using the Graphical Modeling Framework (GMF)

9. EVP : Design • Eclipse Plug-in Development Environment • Allows for Eclipse integration • Allows for natural transitions • from requirements to design • from design to implementation • from implementation to testing • Allows for integration with IBM Rational Software Development Platforms (SDP)

10. EVP : Design • File format: XML and XMI • ROM presentation as XML • First-Cut View as Eclipse generated XMI • ECC Model as Eclipse generated XMI • Improved View as Eclipse generated XMI • Behavioral View as Eclipse generated XMI

11. EVP : Implementation • Java Packages and Classes • com.concordia.read.evp package • EVPActivator class • Extends AbstractUIPlugin which is the abstract base class for all plug-ins that integrate with the Eclipse UI. • EVPLog class • Logging facilities for EVP • Part of the Ready For Rational Software (RFRS) validation program • EVPModels class • Parses XML files, applies rules, and generates models • com.concordia.read.evp.ui package • EVPContextMenu class • Integrates with Eclipse interface to provide context menu for the EVP commands
