4 ATHENA M30 Intermediate Audit, September 2006, Brussels © ATHENA Consortium 2006 DRDS Objectives and Functionalities ● Support the interaction between different people in the project ● Provide different views of requirements ● Requirements’ Elicitation and Analysis ● Requirements’ Classification ● Requirements Negotiation ● Requirements Validation ● Cross Action Line Teams (CAT) Roles ● Repository and management system for interoperability requirements for accessing business and technical needs ● Storing different kind of requirements ● Support requirements collection ● Support change management

5 ATHENA M30 Intermediate Audit, September 2006, Brussels © ATHENA Consortium 2006 DRDS Achievements ● State major achievements ● 519 Requirements ● Classified according to different view points ● Methodology for abstraction (Business needs) and analysis ● Link between Business Needs and Solutions ● Lessons learned ● Interoperability is not a product –fit is a feature of systems ● Direct mapping between solutions and requirements is difficult to achieve ● Guidelines are a key for good requirements quality ● Comparison needs a precise context definition

6 ATHENA M30 Intermediate Audit, September 2006, Brussels © ATHENA Consortium 2006 Mapping Approach Objectives Mapping approach was developed in order to: ● Track the specific solutions that are used to solve specific needs and requirements defined in the Business Scenarios ● To filter this correspondence through a level of abstraction (generic needs/issues against generic solution) in order to: ● allow factorization of common needs coming from different sectors (Aerospace, Telecom, Furniture, Automotive…) or family of application (SCM, e-Procurement, PLM, Portfolio Management…) ● apply gain know-how during ATHENA through the AIF (generic solutions and needs are structured by the AIF) ● Obtain a knowledge base that will allow to continuously improve efficiency of AIF and associated methodology through analysis

Several analysis viewpoints may exist, related to set of context. Generalisation

8 ATHENA M30 Intermediate Audit, September 2006, Brussels © ATHENA Consortium 2006 Mapping Approach Realisation ● A knowledge model was created in OWL, using the Protégé editor: ● Federation of heterogeneous information coming from ATHENA ● No development ● Commercial or proprietary tools independent ● Potential usage of advanced querying or reasoning on the WEB ● Contextualisation ● Identification of context elements coming from the different projects (e.g. phases of Interoperability project methodology from A4) ● Creation of “contextualised_element” class allowing to associate any contextualised element to the context by means of properties ● Contextualisation of solutions and issues by dynamic typing of individuals ● Elaboration of set of queries (in SPARQL) to analyse: ● Quality of contextualisation ● Accuracy of context elements usage to improve interoperability and speed up collaboration... through successive analysis campaigns

9 ATHENA M30 Intermediate Audit, September 2006, Brussels © ATHENA Consortium 2006 DRDS & Mapping Approach ● DRDS application ● operational tool allowing to enter, classify and manage the requirements ● on the WEB, for numerous users (robust, scalable) ● Mapping approach ● Establishment of relationships with information that are not within the DRDS, through context elements that are under continuous development and evaluation within ATHENA ● It was not appropriate to extend the DRDS ● A utility will be used in order to export the content of the DRDS as RDF- XML file that will be integrated in the knowledge base ● Knowledge base was designed in order to allow such an approach
