The different kinds of communication links that can exist in an interaction among objects pose the question of whether every link is or is not an instance of an association, and whether an association must exist whenever there is a communication path between objects. The distinction between static and dynamic associations is not adequate to solve this problem, since in object-orientation every association has static and dynamic features, so that these two aspects do not serve to define two disjoint subtypes of association. Instead, we propose the distinction between structural and contextual associations, which, with an adequate redefinition of association and link stereotypes, helps to maintain the principle that every link is an instance of an association, avoiding the baseless link problem.
The Project "GPS: A platform to model, reuse and measure software process management (TIN-2004-0783)" (funded by Spanish government) has as the main goal to make a tool that helps software engineers satisfy effective practices as they have been defined by most wellknown international institutions such us ISO, SEI[20] and PMI [21]. The purpose of this article is to show the initial phase results of the GPS project. These results were obtained from experience gained by a research team using the most important software process improvement reference models, software process management tools, process modeling languages and the classification techniques in knowledge retrieval.
Abstract. The use of different techniques and tools is a common practice to cover all stages in the development lifecycle generating a very good number of work products under different formats and protocols. This situation implies that a collaborative environment may have the potential of integrating all these data sources creating a real knowledge graph of the development lifecycle easing tasks such as traceability, V&V or quality management. In this light, the OSLC (Open Services for Lifecycle Collaboration) initiative pursues the creation of specifications to unify under a common and shared data model (the Resource Description Framework-RDF) all pieces of information and data involved in the development of a system. The present paper introduces the concept of knowledge management, outlines an OSLC-based specification in the context of Systems Engineering and presents a case study exposing product scheme classifications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
