Data Management with Risk Management in Engineering and Science Projects
Engineering and Science projects are facing new data management challenges, which are currently being addressed through the development of data management plans. However, project stakeholders are unable to proper assess if their plan is representative of good data management practices. To address this issue, we propose a risk management framework to assist the definition of a data management plan in engineering and science projects. To validate our proposal, we present an application to a civil engineering project concerning dam safety.

Designing Digital Preservation Solutions:A Risk Management-Based Approach
Digital preservation aims to keep digital objects accessible over long periods of time, ensuring the authenticity and integrity of these digital objects. In such complex environments, Risk Management is a key factor in assuring the normal behaviour of systems over time. Currently, the digital preservation arena commonly uses Risk Management concepts to assess repositories. In this paper, we intend to go further and propose a perspective where Risk Management can be used not only to assess existing solutions, but also to conceive digital preservation environments. Thus, we propose a Risk Management-based approach to design and assess digital preservation environments, including: ·the definition of context and identification of strategic objectives to determine specific requirements and characterize which consequences are acceptable within the identified context; ·the identification, analysis and evaluation of threats and vulnerabilities that may affect the normal behaviour of a specific business or the achievement of the goals and conformance to the requirements identified in the context characterization; and, ·definition of actions to deal with the risks associated with the identified threats and vulnerabilities. We generalize and survey the main requirements, threats, vulnerabilities and techniques that can be applied in the scope of digital preservation.

Addressing Digital Preservation: Proposals for New Perspectives
Digital preservation aims at maintaining digital objects accessible over long periods of time, ensuring the authenticity and integrity of these digital objects. In this paper, we propose three different approaches to address the digital preservation problem. First, we survey the main requirements specific to the preservation arena. Next, we show how digital preservation can be approached as a specific case of System of Systems Engineering. Then, we introduce Enterprise Architecture as a framework which is regularly used to assist information systems design and maintenance, but can also be applied to System of Systems and consequently to digital preservation. Finally, in such complex environments, Risk Management is a key factor to assure the normal behavior of systems along time. Thus, we propose a Risk Management based approach to design and assess digital preservation environments, enclosing the definition of context and requirements, and the identification of threats and vulnerabilities, to be used as the basis of the definition of actions to deal with the risks associated with those threats and vulnerabilities. We generalize and survey the threats, vulnerabilities and techniques that can be applied in the scope of digital preservation.

Challenges on preserving scientific data with data grids
The emerging context of e-Science imposes new scenarios and requirements for digital preservation. In particular, the data must be reliably stored, for which redundancy is a key strategy. But managing redundancy must take into account the potential failure of component. Considering that correlated failures can affect multiple components and potentially cause a complete loss of data, we propose an innovative solution to manage redundancy strategies in heterogeneous environments such as data grids. This solution comprises a simulator that can be used to evaluate redundancy strategies according to preservation requirements and supports the process to design the best architecture to be deployed, which can latter be used as an observer of the deployed system, supporting its monitoring and management.

Long-term data management and the safety of large civil engineering structures
Large civil engineering structures are continuously monitored to assure their structural safety. The Portuguese National Laboratory for Civil Engineering currently monitors several types of structures, like concrete dams, bridges or other transportation infrastructures. The consequences of a structural failure are potentially catastrophic, varying from loss of life or environmental damage to high economic impacts. The management and preservation of structural monitoring data is crucial to support decisions concerning the structural safety. However, preserving data also entails several risks and threats, comprising strong safety requirements as happens in civil engineering structures.

Preserving Digital Data in Heterogeneous Environments
Digital preservation aims at maintaining digital objects accessible over a long period of time, regardless of the challenges of organizational or technological changes or failures. In particular, data produced in e-Science domains could be reliably stored in todays data grids, taking advantage of the natural properties of this kind of infrastructure to support redundancy. However, to achieve reliability we must take into account failure interdependency. Taking into account the fact that correlated failures can affect multiple components and potentially cause complete loss of data, we propose a solution to evaluate redundancy strategies in the context of heterogeneous environments such as data grids. This solution is based on a simulation engine that can be used not only to support the process of designing the preservation environment and related policies, but also later on to observe and control the deployed system.

Securing the iRODS Metadata Catalog for Digital Preservation
Digital preservation is the ability to retrieve, access, and use digital objects through time, while ensuring the authenticity and integrity properties of these objects. Data grids represent a model of storage systems designed for data management and sharing, which concept also has been proposed for digital preservation. However, since data grids are not specifically designed for this purpose, they present weaknesses that have to be handled. This poster will present a set of services to address a problem in the metadata catalog of the iRODS data grid, strengthening that platform for digital preservation purposes.

Managing Risk Data: From Spreadsheets to Information Systems
The goal of Risk Management is to define prevention and control mechanisms to address the risks attached to specific activities and valuable assets. Many Risk Management efforts operate in silos with narrowly focused, functionally driven, and disjointed activities. That fact leads to a fragmented view of risks, where each activity uses its own language, customs and metrics. That limits an organization-wide perception of risks, where interdependent risks are not anticipated, controlled or managed. The lack of integrated solutions to manage risk information, lead the experts to use spreadsheets as their main tool, impeding collaboration, communication and reuse of risk information. In order to address these issues, this paper presents a solution that integrates a Risk Management framework, including a XML-based Domain Specific Language for Risk Management. The proposed framework is supported by an information system to manage the definition or risks.

A Capability Model for Digital Preservation. Analyzing Concerns, Drivers, Constraints, Capabilities and Maturities
The last decade has seen a number of reference models and compliance criteria for Digital Preservation (DP) emerging. However, there is a lack of coherence and integration with standards and frameworks in related fields such as Information Systems; Governance, Risk and Compliance (GRC); and Organizational Engineering. DP needs to take a holistic viewpoint to accommodate the concerns of information longevity in the increasingly diverse scenarios in which DP needs to be addressed. In addition to compliance criteria, maturity models are needed to support focused assessment and targeted process improvement efforts in organizations. To enable this holistic perspective, this article discusses the question of capability maturity and presents a capability model for DP.We further demonstrate how such an architectural approach can be used as a basis to analyze the impact of criteria and metrics from the ISO Repository Audit and Certification standard on stakeholders, concerns, drivers, goals, and capabilities. The analysis presented here shall contribute to advance the understanding of cross-cutting concerns and the discussion on maturity models in DP.

Archiving Sensor Data - Applied to Dam Safety Information
The consequences of structural failures in large civil engineering structures are potentially catastrophic, varying from high economic impacts to unrecoverable environmental damage or loss of life. To prevent that, these structures can be continuously monitored, therefore the management and preservation of the resulting data is crucial to support decisions concerning structural safety. However, preserving data also entails several risks and threats, comprising strong safety requirements. This paper analyzes the scenario of civil engineering safety, presenting the current systems used at the Portuguese National Laboratory for Civil Engineering to manage and preserve sensor data. The main risks that can impede the digital preservation of data are discussed and a solution is proposed where sensor data is objectively described and packaged in order to be reused in the future. This includes controlling the extraction of data from the operational systems, describing the representation of data through a Metadata Registry, and package the context information using a METS aggregator.

Control Objectives for DP: Digital Preservation as an Integrated Part of IT Governance
Digital Preservation, often seen as information management with a long-term mission, is recognized as an independent research area, but the fields maturity is still evolving. Reference models and compliance criteria for archival systems are being developed, but the more general perspective of Governance, Risk and Compliance has yet to be fully considered. In particular, Digital Preservation can take advantage of the powerful tools for structuring processes to exercise control, assign responsibilities, and quantify goal achievements, provided by IT Governance. This paper presents an integrated vision for Digital Preservation that aligns key organizational preservation processes with a leading framework for IT Governance. Based on a high-level capability model, we define control objectives for core Digital Preservation processes, present a reference assignment of responsibilities and accountabilities to typical Digital Preservation stakeholders, and discuss a maturity model for Digital Preservation processes. The resulting processes are related to key IT Governance processes. This integrated process model enables organizations with a long-term vision on the value of digital information to sustain and govern their Digital Preservation activities.

Integrated management of risk information
Today's competitive environment requires effective risk management activities to create prevention and control mechanisms to address the risks attached to specific activities and valuable assets. One of the main challenges in this area is concerned with the analysis and modeling of risks, which increases with the fact that current efforts tend to operate in silos with narrowly focused, functionally driven, and disjointed activities. This leads to a fragmented view of risks, where each activity uses its own language, customs and metrics. The lack of interconnection and holistic view of risks limits an organization-wide perception of risks, where interdependent risks are not anticipated, controlled or managed. In order to address the Risk Management interoperability and standardization issues, this paper proposes an alignment between Risk Management, Governance and Enterprise Architecture activities, providing a systematic support to map and trace identified risks to enterprise artifacts modeled within the Enterprise Architecture, supporting the overall strategy and governance of any organization. We propose an architecture where risks are defined through a XML-based domain specific language, and integrated with a Metadata Registry to handle risk concerns in the overall organization environment.

Long-term Security of Digital Information
The Digital Preservation community is used to address digital preservation in a problem centric perspective, where the expected common solution is a dedicated Open Archival Information System Reference Model compliant system. In this paper we raise a new perspective to address digital preservation as a long-term information security problem ideally addressed in the origin by the initial information system that has created or makes direct use of the objects where, in some scenario, they can be better protected against several threats that can affect their future interpretation and reuse. In order to achieve this goal, we suggest the use of Risk Management processes in collaboration with Enterprise Architecture processes. The relations between these two processes are detailed, showing how each phase of one process can positively influence a phase on the other process. Finally, in order to illustrate this approach, we present a risk assessment of a scenario concerning dam structural safety information.

Modeling Contextual Concerns in Enterprise Architecture
Enterprise Architecture approaches are used to provide rigorous descriptions of the organization-wide environment, manage the alignment of deployed services to the organization's mission, end ensure a clear separation of the concerns addressed in an architecture. Thus, an effective Enterprise Architecture approach assists in the management of relations and dependencies of any components of the organization environment and supports the integration and evolution of the architecture. However, the quality of that approach is strongly influenced by the precision of the architecture context description, a fact which is not always recognized. This paper focuses on the architecture context description and addresses the gap between the stakeholders' concerns and the resulting architecture. Based on a combination of established references and standards, we show how an explicit integration of the architecture context into the architecture model improves the linking of concerns and key elements of the architecture vision. We apply our approach to a subject of increasing concern in the Information Systems area: longevity of information. Digital preservation is an interdisciplinary problem, but existent initiatives address it in a very domain-centric way, making it impossible to integrate documented knowledge into an overall organization architecture. We analyze several references and models and derive a description of the architecture context and a capability model that supports incremental development through an explicit distinction between systems and their capabilities. The presented approach allows not just any organization to assess their current digital preservation awareness and evolve their architectures to address this challenge, but in particular demonstrates the added value of an explicit architecture context model in an Enterprise Architecture approach.

Modeling Digital Preser vation Capabilities in Enterprise Architecture
The rising awareness of the challenges of preserving information over the long term has led to a wealth of initiatives developing economic models, methods, tools, systems, guidelines and standards for digital preservation. The challenge of digital preservation is to assure that information nowadays coded and stored in digital formats can be read and be used in an unforeseen future. This is an interdisciplinary problem combining organizational and technical challenges. However, to date there is no unified view on how to approach the problem from a holistic perspective and align organizational and technical issues in a systems engineering approach. Organizations that aim to add digital preservation to their abilities generally have difficulties to assess their existing systems and what capabilities and components they are missing in order to address the needs of trustworthy information longevity. In this paper we present an approach that enables us to accommodate the concerns of digital preservation in Enterprise Architecture practice. We discuss key elements of a generic reference architecture for digital preservation and a capability model based on established domain-specific reference models. Distilling these knowledge sources into a consistent and coherent view allows baseline assessment and incremental capability development in typical IT governance scenarios where an IT architecture already exists. We illustrate this with the assessment of a government agency's existing capabilities and systems against emerging digital preservation requirements.

On the relevance of Enterprise Architecture and IT Governance for Digital Preservation
Digital Preservation has been recognized as a key challenge in providing trusted information and sustainable eGovernment services. However, there has been little convergence on aligning the technically oriented approaches to provide longevity of information in ever-changing technology environments, and the organizational problems that public bodies are facing, through a systematic framework that aligns organizational and technological issues in the social domain of eGovernment. In this paper, we discuss the relevance of Enterprise Architecture and IT Governance for digital preservation and analyze key frameworks for digital preservation from this viewpoint. We assess the coverage of the leading criteria catalog for trustworthy repositories in terms of Enterprise Architecture dimensions and in how far these criteria align with established Enterprise Architecture and IT Governance frameworks. We discuss the analysis process we were following and present key observations that result from our work. These point to a number of steps that should be taken in order to consolidate digital preservation approaches and frameworks and align them with established frameworks and best practice models in Enterprise Architecture and IT Governance.

Risk Assessment in Digital Preservation of e-Science Data and Processes
Risk is a constant in every area and at all levels of any organization, whether in a general context or in a specific activity, project or function. Risk Management comprises a set of coordinated activities to direct and control an organization with regard to risk. Risk Assessment is considered the most important phase of Risk Management, which consists in identifying, analyzing and evaluating risks. Digital preservations main concern is to keep information accessible and understandable over a long period of time, through means of digital objects; therefore, it is an area that needs a thorough Risk Management and, especially, a thorough Risk Assessment. In fact, the digital preservation process can be seen as Risk Management activities to protect digital information from inherent threats and vulnerabilities. The digital preservation problem can be even more complex in the context of e-Science, which is progressively being considered as a reference method for experimental scientific discovery, and whose data and processes need to be handled and preserved. As such, this paper analyzes the applicability of Risk Assessment techniques, in the context of digital preservation and, more concretely, in the preservation of e-Science data and processes, in order to develop a Risk Assessment method that can be applied while managing the life-cycle of digital information.

Processo Iterativo de Migração de Dados
Com a evolução das tecnologias de informação, a migração de dados legados é essencial para garantir o correcto funcionamento das novas aplicações. A eficiência e correcção das aplicações depende, fortemente, da qualidade dos dados armazenados. A criação de processos de migração de dados através da implementação de Software específico é bastante complexa. Por isso, é fundamental disponibilizar mecanismos de apoio à realização de tarefas de tratamento e migração de dados. A framework Ajax disponibiliza vários operadores para limpeza e transformação de dados. Não sendo uma ferramenta exclusivamente orientada para a migração de dados, pretende-se que a sua utilização na migração de um projecto real permita validar a respectiva aplicação. Todas as lacunas dos operadores do Ajax podem, assim, ser preenchidas através do refinamento e extensão da lógica dos operadores, nomeadamente, no suporte à identificação de registos errados e ao carregamento incremental de dados nos sistemas alvo. No âmbito do projecto gestBarragens, desenvolveu-se um processo de migração que inclui o carregamento de um sistema de informação legado e vários sistemas simples relacionados com informação acerca da segurança de barragens de betão em Portugal.

Workflow modeling using UML, Declarative Tools and WEB2.0
Manual translation of UML diagrams to programmatic code is tedious and error prone. Many CASE tools allow computer code to be generated from Class Diagrams, but fewer, if any, allow the transformation of Activity Dia- grams (ADs) in executable and workflow defining computer code. Our project aims at: Translating UML ADs into the ISCO programming language; Building a workflow execution system that runs the translations; Building a graphical tool to create and edit workflows, and visualize the executions. Defending that UML ADs can specify executable workflows, we present an ISCO based workflow engine, acting over the information extracted from Activity Diagrams and integrated into a platform that allows a user to graph- ically model and manage workflows within a web environment. The server, built with ISCO, assures the data persistence and the execution of the work- flows. Communication with the server is performed through AJAJ.
