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).

Generation of Interface Control Documents (ICDs) using a model-based method has a number of advantages over text-based approaches. This paper describes the Python-based software that was written to automatically generate different versions of an ICD from a structure model in Capella. One use case for this approach is checking parts changes captured in the Engineering Bill of Materials (EBOM) using a PLM tool. We demonstrate an automated workflow that links changes in the EBOM to a request to vet the change against the ICD. This presentation will discuss our rationale, approach, results, and lessons learned.

Clipper: A Low-Latency Online Prediction Serving System: Spark Summit East ta...Spark Summit
Machine learning is being deployed in a growing number of applications which demand real-time, accurate, and robust predictions under heavy query load. However, most machine learning frameworks and systems only address model training and not deployment.
In this talk, we present Clipper, a general-purpose low-latency prediction serving system. Interposing between end-user applications and a wide range of machine learning frameworks, Clipper introduces a modular architecture to simplify model deployment across frameworks. Furthermore, by introducing caching, batching, and adaptive model selection techniques, Clipper reduces prediction latency and improves prediction throughput, accuracy, and robustness without modifying the underlying machine learning frameworks. We evaluated Clipper on four common machine learning benchmark datasets and demonstrate its ability to meet the latency, accuracy, and throughput demands of online serving applications. We also compared Clipper to the Tensorflow Serving system and demonstrate comparable prediction throughput and latency on a range of models while enabling new functionality, improved accuracy, and robustness.

[SEBD2020] OLAP Querying of Document Stores in the Presence of Schema VarietyUniversity of Bologna
Paper presented at SEBD 2020
Document stores are preferred to relational ones for storing heterogeneous data due to their schemaless nature. However, the absence of a unique schema adds complexity to analytical applications. In a previous paper we have proposed an original approach to OLAP on document stores; its basic idea was to stop fighting against schema variety and welcome it as an inherent source of information wealth in schemaless sources. In this paper we focus on the querying phase, showing how queries can be directly rewritten on a heterogeneous collection in an inclusive way, i.e., also including the concepts present in a subset of documents only.

The field of machine programming — the automation of the development of software — is making notable research advances. This is, in part, due to the emergence of a wide range of novel techniques in machine learning. In today’s technological landscape, software is integrated into almost everything we do, but maintaining software is a time-consuming and error-prone process. When fully realized, machine programming will enable everyone to express their creativity and develop their own software without writing a single line of code. Intel realizes the pioneering promise of machine programming, which is why it created the Machine Programming Research (MPR) team in Intel Labs. The MPR team’s goal is to create a society where everyone can create software, but machines will handle the “programming” part.

iStarJSON: A Lightweight Data-Format for i* ModelsGESSI UPC
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.
Towards iStarML 2.0: Closing Gaps from Evolved RequirementsGESSI UPC
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
Organizations are increasingly becoming Open Source Software (OSS) adopters, either as a result of a strategic decision or just as a consequence of technological choices. The strategy followed to adopt OSS shapes organizations’ businesses; therefore methods to assess such impact are needed. In this paper, we propose OSSAP, a method for defining OSS Adoption business Processes, built using a Situational Method Engineering (SME) approach. We use SME to combine two well-known modelling methods, namely goal-oriented models (using i*) and business process models (using BPMN), with a pre-existing catalogue of goal-oriented OSS adoption strategy models. First, we define a repository of reusable method chunks, including the guidelines to apply them. Then, we define OSSAP as a composition of those method chunks to help organizations to improve their business processes in order to integrate the best fitting OSS adoption strategy. We illustrate it with an example of application in a telecommunications company.
Aligning Business Goals and Risks in OSS AdoptionGESSI UPC
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.
Jcis 2015-Towards Assessing Open Source Communities' Health using SOC ConceptsGESSI UPC
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.

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.
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.
QuESo: a Quality Model for Open Source Software EcosystemsGESSI UPC
Open source software has witnessed an exponential growth in the last two decades and it is playing an increasingly
important role in many companies and organizations leading to the formation of open source software
ecosystems. In this paper we present a quality model that will allow the evaluation of those ecosystems in
terms of their relevant quality characteristics such as health or activeness.
To take maximum advantage of open source software (OSS), the understanding, management and mitigation of OSS adoption risks is crucial. We describe the empirical application of the tactical workshops with the purpose of obtaining the domain expert evaluation.
MoDRE 2014 @ RE keynote -- NFR-Aware MDD ProcessesGESSI UPC
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. Based on research done with other members of the GESSI group in collaboration with other research teams
Quantifying the Impact of OSS Adoption Risks with the help of i* ModelsGESSI UPC
Dolors Costal, Daniel Gross, Lidia Lopez, Mirko Morandini, Alberto Siena, Angelo Susi: Quantifying the Impact of OSS Adoption Risks with the help of i* Models. 7th i* Int. Workshop held at CAiSE 2014. Paper at http://ceur-ws.org/Vol-1157/paper10.pdf. 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.
Applying Business Strategy Models in OrganizationsGESSI UPC
Lidia López, Xavier Franch: Applying Business Strategy Models in Organizations. 7th i* Int. Workshop held at CAiSE 2014. Paper at http://ceur-ws.org/Vol-1157/paper6.pdf.
Abstract. 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.
A Context Ontology for Service Provisioning and ConsumptionGESSI UPC
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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Metamodel – SRP Structure
A patternrepresents a cluster of
requirements (a group of
interrelatedrequirements).
Example:
Failure Alerts
A requirement
pattern…
A form captures a particular context that may
be the most appropiatefor a software project.
… has several
forms …
Examples:
Homogeneous Failure Alerts
Heterogeneous Failure Alerts

For declaring multiplicities or dependencies
among parts.
Examples:

A fixed partcontainsthemost
abstractexpression of a requirement.
A extended part contains other ways to
express a requirement (often with parameters).
Example:
The system shall trigger an
alert in case of failure.
Examples:
The system shall trigger an alert in

Validation
• During building the catalogue and metamodel:
SSI conducted two case studies to do an initial
validation:
1. Improve the contents and the metamodel of the catalogue:
the first one (a digital library system).
2. Catalogue validation: the second one (a CRM SaaS project)
used fro validation to obtain feedback of the adequacy of the
resulting catalogue.
• All the approach:
SSI did a small project for a company (July 2010):
• 29 NFRs stated using 21 different SRPs.
(only 2 reqs didn’t become from SRPs!)
21
25. GESSI: Software Requirement Patterns
Future Work
•
Validation of the approach (catalogue, method, tool,
etc.):
Call-for-tender processes: collaboration of SSI-CPRHT and
CASSIS consultants.
Other different domains.
•
Improve and expand tools’ functionalities.
Interoperability with other requirement engineering tools (Irqa,…).
•
•
Expand SRP catalogue with other types of requirements
(non-technical, functional).
Automatic computation of patterns from requirement
books.
