Open source software ecosystem modelling has emerged asan important research area in software engineering. Several models havebeen proposed to identify and analyse the complex relationships in OSS-ecosystems. However, there is a lack of formal models, methodologies,tool support, and standard notations for OSS-ecosystems. In this paperwe propose a general framework for support the OSS-ecosystems mod-elling process. This framework will allow the representation, synthesis,analysis, evaluation, and evolution of OSS-ecosystems. Design sciencemethodology is proposed to create several artefacts and investigatingthe suitability of these artefacts in the OSS-ecosystem context.

This thesis provides a formal proposal for the specialization relationship in the i* framework that allows its use in a well-defined manner. I root my proposal over existing works in different areas that are interested in representing knowledge: knowledge representation from Artificial Intelligence and conceptual modeling and object-oriented programming languages from Software Development. Also, I use the results of a survey conducted in the i* community that provides some insights about what i* modelers expect from specialization. As a consequence of this twofold analysis, I identify three specialization operations: extension, refinement and redefinition. For each of them, I: • motivate its need and provide some rationale; • distinguish the several cases that can occur in each operation; • define the elements involved in each of these cases and the correctness conditions that must be fulfilled; • demonstrate by induction the fulfilment of the conditions identified for preserving satisfaction; • provide some illustrative examples in the context of an exemplar about travel agencies and travelers. The specialization relationship is offered by the i* framework through the is-a construct defined over actors (a subactor is-a superactor) since it was first released. Although the overall meaning of this construct is highly intuitive, its effects at the level of intentional elements and dependencies are not always clear, hampering seriously its appropriate use. In order to be able to reason about correctness and satisfaction, I define previously the conditions that must be preserved when a specialization takes place. In addition, I provide a methodology with well-defined steps that contextualize the formal aspects of this thesis in a development process. As a conclusion, this thesis is making possible the use of the specialization relationship in i* in a precise, non-ambiguous manner.

Quality of an open source software ecosystem (OSS ecosystem) is key for dierent ecosystem actors such as contributors or adopters. In fact, the consideration of several quality aspects(e.g., activeness, visibility, interrelatedness, etc.) as a whole may provide a measure of the healthiness of OSS ecosystems. The more health a OSS ecosystem is, the more and better contributors and adopters it will gather. Some research tools have been developed to gather specic quality information from open source community data sources. However, there exist no frameworks available that can be used to evaluate their quality as a whole in order to obtain the health of an OSS ecosystem. To assess the health of these ecosystems, we propose to adopt robust principles and methods from the Service Oriented Computing field.

These are the slides of my ICSME 2016 keynote, presented on 5 October 2016 in Raleigh, North Carolina. I focus on the difficulties of maintaining and evolving software ecosystems, large collections of interacting software components that are maintained by a large and active community of contributors and that evolve together in the same environment. Software ecosystems are becoming ubiquitous due to the omnipresence of open source software. I present several problems that arise during maintenance and evolution of software ecosystems, and I argue how some of these challenges should be addressed by adopting a socio-technical view and by relying on a multidisciplinary and mixed methods research approach. I illustrate this with examples of social network analysis, complex systems research, ecological biodiversity, and survival analysis.

Applying systemic methodologies to “IT ecosystems” in order to harmonize business operations and information systems within the organization Software ecosystems and IT ecosystems are modern terms used to describe complex networks of IT applications. The idea comes from the perspective that IT systems are made by people, serve people in the context of socio-technical systems and, finally, they affect the lives of more people. All that stuff live and evolve together, each having its own properties and dynamics. All together form a kind of ecosystem which exposes its own emergent behavior. It is a perfect field to apply systemic approach in order to create a holistic approach, to reveal the underlying dynamic structure, to cope with complexity and to extract order out of the mess. The final objective is to bridge the gap between business and IT helping the organization to serve its purpose.

Multiagent Based Methodologies have become an important subject of research in advance Software Engineering. Several methodologies have been proposed as, a theoretical approach, to facilitate and support the development of complex distributed systems. An important question when facing the construction of Agent Applications is deciding which methodology to follow. Trying to answer this question, a framework with several criteria is applied in this paper for the comparative analysis of existing multiagent system methodologies. The results of the comparative over two of them, conclude that those methodologies have not reached a sufficient maturity level to be used by the software industry. The framework has also proved its utility for the evaluation of any kind of Multiagent Based Software Engineering Methodology

The spirit of free/open-source development has from the begining been well in line with that of academic research: freedom in software distribution is similar to freedom in dissemination of scientific knowledge. Now that F/OSS hit the business world, new questions arised on the possibility to run sustainable business models based on F/OSS - the question of innovation being a central part of the answer. This presentation will discuss the relationships between: the open-source development process; open innovation in sowftare; academic research; its funding and industrial valorization; and public policies for the information society.

Dr. Steve Dam will walk you through the process of using Innoslate’s modeling and simulation capabilities while applying a MBSE methodology. At its core, Innoslate is a full model-based systems engineering tool. Within Innoslate, system models are formalized and capable of simulation to derive cost, schedule, and performance data. Your webinar will cover: Functional modeling Functional modeling is at the heart of how Innoslate derives new requirements and ensures logical accuracy. Physical modeling We can describe synthesizing the physical model in Innoslate with eight different diagrams, including the Asset Diagram, Layer Diagram, Block Definition Diagram, and Internal Block Diagram. Executing a model Innoslate includes a ‘Discrete Event Simulator’ to verify functional diagram’s logic, calculate cost, compute time, and quantify performance. Relating Requirements to Diagrams Requirements traceability ensures that the lifecycle and origin of a requirement is fully tracked. Innoslate includes relationship matrices to represent traceability relationships between entities in tabular view. Requirements Generation After modeling the system, often an engineer will derive textual requirements from the models by hand. Innoslate includes an automatic facility that generates requirements documents in a standard format (as outlined in “The Engineering Design of Systems: Models and Methods“).

JSON is one of the most widely used data-interchange format. There is a large number of tools open for modelling with i*. However, none of them provides supporting for JSON. In this paper we propose iStarJSON language, a JSON-based proposal for interchanging i* models. We also, present an open source software that transforms XML-based format models to JSON models that expose a set of web services for mining iStarJSON models.

iStarML is an XML-based format for enabling interoperability among i* tools. Its main design focus was to support data interchange even when involved tools implement different i* variants. In this paper we analyse required changes to the format from two main sources (i) the evolution of i* into a consistent and clear set of core concepts expressed in the new iStar 2.0 specification and (ii) recurrent necessities due to a wide use of i* modelling. In order to address these requirements, we propose new XML elements to be considered in a new version of iStarML: iStarML2.0

Increasing adoption of Open Source Software (OSS) requires a change in the or-ganizational culture and reshaping IT decision-makers mindset. Adopting OSS software components introduces some risks that can affect the adopter organiza-tion’s business goals, therefore they need to be considered. To assess these risks, it is required to understand the socio-technical structures that interrelate the stake-holders in the OSS ecosystem, and how these structures may propagate the po-tential risks to them. In this paper, we study the connection between OSS adop-tion risks and OSS adopter organizations’ business goals . We propose a model-based approach and analysis framework that combines two existing frameworks: the i* framework to model and reason about business goals, and the RiskML no-tation to represent and analyse OSS adoption risks. We illustrate our approach with data drawn from an industrial partner organisation in a joint EU project.

Increasing adoption of Open Source Software (OSS) in information system engineering has led to the emergence of different OSS business strategies that affect and shape organizations’ business models. In this context, organizational modeling needs to reconcile efficiently OSS adoption strategies with business strategies and models. In this paper, we propose to embed all the knowledge about each OSS adoption strategy into an i* model that can be used in the intentional modeling of the organization. These models describe the consequences of adopting one such strategy or another: which are the business goals that are supported, which are the resources that emerge, etc. To this aim, we first enumerate the main existing OSS adoption strategies, next we formulate an ontology that comprises the activities and resources that characterise these strategies, then based on the experience of 5 industrial partners of the RISCOSS EU-funded project, we explore how these elements are managed in each strategy and formulate the corresponding model using the i* vframework.

Software systems cannot be successful without taking non-functional requirements (NFRs) into account. But still there seems to be a lopsided emphasis on the functionality of the system, even though the functionality is not useful or usable when NFRs do not hold. MDD is not an exception to this rule. In this keynote, we will first analyse the state of the art in MDD with respect to NFR treatment. Next, we will reflect on the possible ways to fit NFRs in the MDD process and the consequences of each alternative. At the end, we will discuss a research agenda.

Adopting Open Source Software (OSS) components in or ganisational settings requires evaluating the possible impact of adoption decisions on business goals. Measures available in OSS, capturing indicators such as the quality of open source code and the activeness of the developing community, can be used as a driver to assess various risks in component adoption. In this paper we illustrate how risk and impact models are used to relate measures obtained from the component under analysis to business goals in i* -based OSS business strategy models.

Increasing adoption of Open Source Software (OSS) in information system engineering has led to the emergence of different OSS business strategies that affect and shape organizations’ business models. In order to obtain the specific organizational model for a concrete organization that is adhering to a specific OSS business strategy, we need to instantiate the general knowledge included in this business strategy. This paper describe the process in which this general knowledge is instantiated and define a set of operations over i* models to implement the instantiation concept. Although conceived in the field of OSS, the approach is generalizable to any kind of business strategy.

Nowadays services as those provided by smart cities, health smart services, as well as common services (e.g., telephonic services, e-mail services), have a great economic impact for organisations and represent an important mean to deliver value to their consumers. The malfunctions of both the services themselves as well as the entities responsible for their execution and consumption might cause economic losses, consumers’ dissatisfaction and even shorten the service life cycle, among other risks. To avoid malfunctions beyond maintaining quality levels desired, it is important to take into account the widest possible context information that cause either positive or negative effects around services and entities involved in their provisioning and consumption. In this paper, we propose an upper ontology for service provisioning and consumption from a service-centric perspective. Specifically, we focus on software services, although we could argue for more generic applications. The contribution is the analysis, evaluation and reuse of existing proposals on context models to identify the strengths and weaknesses of its current status as well as to identify contexts not yet considered, and consolidate an integrated view of these proposals. The ultimate intention is to provide a well-defined and consolidated infrastructure of context information as a common body of knowledge, that could be instantiated on variety of use cases, for example, to be instantiated by monitors as context information useful to be monitored, or to be used as context information that allows knowing which contexts affect a service when a user consumes it, among others.

The quality of Open Source Software products is directly related to its community’s health. To date, health analysis is made accessing available data repositories or using software management tools that are often too static or ad hoc. To address this issue, we propose to adopt principles and methods from the Service Oriented Computing field. Particularly, we propose to adapt the concepts of quality service and service level agreement, and propose to reuse the existing body of knowledge and techniques from SOC monitoring. To demonstrate the feasibility of the approach, we use a service monitoring framework called SALMonOSS as a proof of concept to realize the implementation of the proposal. ---- Presentation in RCIS 2014

There are many approaches to reuse in software engineering. Among them, patterns hold a prominent position. "Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice" (Alexander, 1979). We are interested in the use of patterns for the requirements analysis stage, namely Software Requirement Patterns. The patterns applicability to this context is clear, since requirements that appear over and over in requirements books could be identified as the solution to particular problems in a given context (the classical context-problem-solution scenario of patterns).

Education system forms the backbone of every nation. And hence it is important to provide a strong educational foundation to the young generation to ensure the development of open-minded global citizens securing the future for everyone. Advanced technology available today can play a crucial role in streamlining education-related processes to promote solidarity among students, teachers and the school staff. School Management System(SMS) consists of tasks such as registering students, attendance record keeping to control absentees, producing report cards, producing official transcript, preparing timetable and producing different reports for teachers, officials from Dr.Mohiuddin Education foundation and other stakeholders. Automation is the utilization of technology to replace human with a machine that can perform more quickly and more continuously. By automating SMS documents that took up many large storage rooms can be stored on few disks. Transcript images can be annotate. It reduces the time to retrieve old transcripts from hours to seconds.
