Semantics of trace relations in requirements models for consistency checking and inferencing
Requirements traceability is the ability to relate requirements back to stakeholders and forward to corresponding design artifacts, code, and test cases. Although considerable research has been devoted to relating requirements in both forward and backward directions, less attention has been paid to relating requirements with other requirements. Relations between requirements influence a number of activities during software development such as consistency checking and change management. In most approaches and tools, there is a lack of precise definition of requirements relations. In this respect, deficient results may be produced. In this paper, we aim at formal definitions of the relation types in order to enable reasoning about requirements relations. We give a requirements metamodel with commonly used relation types. The semantics of the relations is provided with a formalization in first-order logic. We use the formalization for consistency checking of relations and for inferring new relations. A tool has been built to support both reasoning activities. We illustrate our approach in an example which shows that the formal semantics of relation types enables new relations to be inferred and contradicting relations in requirements documents to be determined. The application of requirements reasoning based on formal semantics resolves many of the deficiencies observed in other approaches. Our tool supports better understanding of dependencies between requirements
Integrating the common variability language with multilanguage annotations for web engineering
Web applications development involves managing a high diversity of files and resources like code, pages or style sheets, implemented in different languages. To deal with the automatic generation of
custom-made configurations of web applications, industry usually adopts annotation-based approaches even though the majority of studies encourage the use of composition-based approaches to implement
Software Product Lines. Recent work tries to combine both approaches to get the complementary benefits. However, technological companies are reticent to adopt new development paradigms
such as feature-oriented programming or aspect-oriented programming.
Moreover, it is extremely difficult, or even impossible, to apply
these programming models to web applications, mainly because of
their multilingual nature, since their development involves multiple
types of source code (Java, Groovy, JavaScript), templates (HTML,
Markdown, XML), style sheet files (CSS and its variants, such as
SCSS), and other files (JSON, YML, shell scripts). We propose to
use the Common Variability Language as a composition-based approach
and integrate annotations to manage fine grained variability
of a Software Product Line for web applications. In this paper, we (i)
show that existing composition and annotation-based approaches,
including some well-known combinations, are not appropriate to
model and implement the variability of web applications; and (ii)
present a combined approach that effectively integrates annotations
into a composition-based approach for web applications. We implement
our approach and show its applicability with an industrial
real-world system.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
Why and How Your Traceability Should Evolve: Insights from an Automotive Supplier
Traceability is a key enabler of various activities in automotive software
and systems engineering and required by several standards. However, most
existing traceability management approaches do not consider that traceability
is situated in constantly changing development contexts involving multiple
stakeholders. Together with an automotive supplier, we analyzed how technology,
business, and organizational factors raise the need for flexible traceability.
We present how traceability can be evolved in the development lifecycle, from
early elicitation of traceability needs to the implementation of mature
traceability strategies. Moreover, we shed light on how traceability can be
managed flexibly within an agile team and more formally when crossing team
borders and organizational borders. Based on these insights, we present
requirements for flexible tool solutions, supporting varying levels of data
quality, change propagation, versioning, and organizational traceability.Comment: 9 pages, 3 figures, accepted in IEEE Softwar
A design recording framework to facilitate knowledge sharing in collaborative software engineering
This paper describes an environment that allows a development team to share knowledge about software artefacts
by recording decisions and rationales as well as supporting the team in formulating and maintaining design constraints. It explores the use of multi-dimensional design spaces for capturing various issues arising during development and presenting this meta-information using a network of views. It describes a framework to underlie the collaborative environment and shows the supporting architecture and its implementation. It addresses how the artefacts and their meta-information are captured in a non-invasive way and shows how an artefact repository is embedded to store and manage the artefacts
Environments to support collaborative software engineering
With increasing globalisation of software production, widespread use of
software components, and the need to maintain software systems over long
periods of time, there has been a recognition that better support
for collaborative working is needed by software engineers.
In this paper, two approaches to developing
improved system support for collaborative software engineering are
described: GENESIS and OPHELIA.
As both projects are moving towards industrial trials and eventual publicreleases of their systems, this exercise of comparing and
contrasting our approaches has provided the basis for future
collaboration between our projects particularly in carrying out
comparative studies of our approaches in practical use
Grand Challenges of Traceability: The Next Ten Years
In 2007, the software and systems traceability community met at the first
Natural Bridge symposium on the Grand Challenges of Traceability to establish
and address research goals for achieving effective, trustworthy, and ubiquitous
traceability. Ten years later, in 2017, the community came together to evaluate
a decade of progress towards achieving these goals. These proceedings document
some of that progress. They include a series of short position papers,
representing current work in the community organized across four process axes
of traceability practice. The sessions covered topics from Trace Strategizing,
Trace Link Creation and Evolution, Trace Link Usage, real-world applications of
Traceability, and Traceability Datasets and benchmarks. Two breakout groups
focused on the importance of creating and sharing traceability datasets within
the research community, and discussed challenges related to the adoption of
tracing techniques in industrial practice. Members of the research community
are engaged in many active, ongoing, and impactful research projects. Our hope
is that ten years from now we will be able to look back at a productive decade
of research and claim that we have achieved the overarching Grand Challenge of
Traceability, which seeks for traceability to be always present, built into the
engineering process, and for it to have "effectively disappeared without a
trace". We hope that others will see the potential that traceability has for
empowering software and systems engineers to develop higher-quality products at
increasing levels of complexity and scale, and that they will join the active
community of Software and Systems traceability researchers as we move forward
into the next decade of research

EDI - XML Standards and Technologies in the Agri-Food Industry
Due to globalisation, the new technological developments and the complexity of food
supply processes, the European food sector is increasingly becoming more complex. The consumers’
trust in food, triggered and affected by a number of food crises, is low. Today, consumers increasingly
expect safe and high quality food and demand information about the origin of their food. Also, the
economic health of the food industry can be greatly affected by food crises; therefore, efficient and
effective mechanisms are required to assist the food industry in tracking and tracing products along the
food chain. In this paper, we discuss the criteria for an efficient and effective traceability system from
an IT perspective (mainly data exchange) and we identify key requirements for ICT enabled
traceability
