The gCube interoperability framework
Candela L, Kakaletris G, Pagano P, Papanikos G, Simeoni F
Interoperability is one of the most challenging issues in the design and operation of large-scale computing infrastructures for multidisciplinary research. It requires solutions that can "embrace" heterogeneity, i.e. accommodate multiple incarnations of similar resources, as well as "hide" it, i.e. provide consumers with a homogeneous view of diverse resources. This paper overviews the measures put in place in the D4Science infrastructure to address a range of interoperability problems.Project(s): D4SCIENCE

On digital library foundations
Candela L, Castelli D, Fox E A, Ioannidis Y
The cultural infrastructure provides for the transmission of culture from creators to audiences. The access to this infrastructure is the key issue. The network technology will radically transform the interaction with knowledge. The base infrastructure will be knowledge networks rather than data networks. Digital libraries would become the universal knowledge repositories and communication conduits of the future. These digital libraries should enable any citizen to access human knowledge any time and anywhere, in a friendly, multi-modal, efficient and effective way. Ideally the infrastructure combines concepts and techniques from Grid computing. It would be an opportunity to open cultural infrastructure.Source: INTERNATIONAL JOURNAL ON DIGITAL LIBRARIES (PRINT), vol. 11 (issue 1), pp. 37-39

Building large heterogeneous interconnected digital library infrastructures: the interoperability challenge
Thanos C, Candela L, Castelli D
Interoperability is a multi-layered and context-specific concept, crucial when building heterogeneous interconnected Digital Library infrastructures. It encompasses different levels along a multidimensional spectrum. Two key problems hinder the achievement of interoperability: (i) the heterogeneity of the exchanged information which covers all types of syntactic, structural, and semantic diversities among systems used to modelling information and (ii) the inconsistency between the use of the information as intended by its originator and the intended exploitation of it by the recipient. Building heterogeneous interconnected Digital Library infrastructures requires addressing all dimensions of interoperability including content, user, functionality, architecture, quality, and policy. In this paper a comprehensive study of the interoperability issues involved when building interoperable Digital Libraries is performed.Project(s): DL.ORG

Deploying general-purpose virtual research environments for humanities research
Blanke T, Candela L, Hedges M, Priddy M, Simeoni F
Several virtual research environments (VREs) have been developed to address specific tasks or application domains. Building on the experiences and use cases coming out of these projects, this paper addresses the creation of more general-purpose VREs for the humanities, which move beyond specific, focused tasks, and instead provide services and environments that support more general-purpose humanities research activities. Specifically, we are investigating use cases related to the organization and integration of the dispersed and heterogeneous information on which such research is based. These use cases are highly interactive, interpretative and researcher centric, addressing topics such as annotation environments and support for 'active-reading' processes and scholarly dialogues. We present the background to our work and the technical approach taken, and report the results obtained so far.Source: PHILOSOPHICAL TRANSACTIONS - ROYAL SOCIETY.

General-purpose digital library content laboratory systems
Manghi P., Mikulicic M., Candela L., Artini M., Bardi A.
In this work, we name Digital Library Content Laboratories (DLCLs) software systems specially devised for aggregating and elaborating over information objects - e.g., publications, experimental data, multimedia and compound objects - collected from possibly heterogeneous and autonomous data sources. We present a general-purpose and cost-efficient system for the construction of customized DLCLs, based on the D-NET Software Toolkit. D-NET offers a service-oriented framework, where developers can choose the set of services they need, customize them to match domain requirements, and combine them in a "LEGO fashion" to obtain a personalized DLCL. D-NET is currently the enabling software of several DLCLs, operated by European Commission projects and national initiatives.Source: ECDL 2010 - Research and Advanced Technology for Digital Libraries. 14th European Conference, pp. 14–21, Glasgow, UK, 6-10 September 2010

Realizing and maintaining aggregative digital library systems: D-NET software toolkit and OAIster system
Manghi P, Mikulicic M, Candela L, Castelli D, Pagano P
Aggregative Digital Library Systems (ADLSs) provide end users with web portals to operate over an information space of descriptive metadata records, collected and aggregated from a pool of possibly heterogeneous repositories. Due to the costs of software realization and system maintenance, existing "traditional" ADLS solutions are not easily sustainable over time for the supporting organizations. Recently, the DRIVER EC project proposed a new approach to ADLS construction, based on Service-Oriented Infrastructures. The resulting D-NET software toolkit enables a running, distributed system in which one or multiple organizations can collaboratively build and maintain their service-oriented ADLSs in a sustainable way. In this paper, we advocate that D-NET's "infrastructural" approach to ADLS realization and maintenance proves to be generally more sustainable than "traditional" ones. To demonstrate our thesis, we report on the sustainability of the "traditional" OAIster System ADLS, based on DLXS software (University of Michigan), and those of the "infrastructural" DRIVER ADLS, based on D-NET.Source: D-LIB MAGAZINE, vol. 16 (issue 3-4), pp. 1-17

An event-centric provenance model for digital libraries
Castelli D, Candela L, Manghi P, Pagano P, Tang C, Thanos C
Provenance is intended as the description of the origin and/or of the descendant line of data. In the last decade, keeping track of provenance has become crucial for the correct exploitation of data in a wide variety of application domains. The rapid evolution of digital libraries, which have become today advanced systems for the integration and management of cross-domain digital objects, recently called for models capturing the aspects of data provenance in this application field. However, there is no common definition of digital library provenance and existing solutions address the problem only from the perspective of specific application scenarios. In this paper we propose a provenance model for digital libraries, inspired by approaches and experiences in the e-Science and cultural heritage worlds and based on the notion of event occurred to an object. The model aims at capturing the specificities of provenance for digital libraries objects in order to provide practitioners and researchers in the field with common DL-specific provenance description languages.DOI: 10.1007/978-3-642-15850-6_9

Making digital library content interoperable
Candela L, Castelli D, Thanos C
The demand for powerful and rich Digital Libraries able to support a large variety of interdisciplinary activities has increased the need for "building by re-use" and sharing, especially when dealing with the content space. Interoperability is a central issue to satisfy these needs. Despite its importance, and the many attempts to address it done in the past, the solutions to this problem are today, however, still very limited. Main reasons for this slow progress are lack of any systematic approach for addressing the issue and scarce knowledge of the adopted solutions. Too often these remain confined to the systems they have been designed for. In order to overcome this lack, this paper proposes an Interoperability Framework for describing and analyzing interoperability problems and solutions related to use of content resources. It also discusses the many facets content interoperability has and provides a comprehensive and annotated portfolio of existing approaches and solutions to this challenging issue.Source: COMMUNICATIONS IN COMPUTER AND INFORMATION SCIENCE (PRINT), pp. 13-25

Interoperability patterns in digital library systems federations
Manghi P, Candela L, Pagano P
Service providers willing to offer functionality over an aggregation of information objects are becoming the key actors in the Digital Library world. This aggregation is usually performed by collecting and processing objects from a federation of data providers - e.g., institutional repositories, data archives - through wellknown standard protocols for data-exchange. Higher-level interoperability problems affect these scenarios and determine the quality of the service offered by and the success of these providers initiatives. Interoperability problems are mainly due to the impedance mismatch occurring between data models of the objects to be exported by data providers and the data model of the service provider and can be measured in terms of "structural heterogeneity", "semantic heterogeneity", and "granularity-ofrepresentation heterogeneity". In this paper, we define a basic architecture through which we describe the interoperability patterns arising when constructing such a federations and present the D-NET Software Toolkit as a general-purpose practical solution to these issues.

Building an e-infrastructure for capture statistics and species distribution modeling: the D4science approach
Ellenbroek A, Candela L, Castelli D, Pagano P, Taconet M
Fisheries Resources Management has an ever increasing demand for capture data with ever finer geographical resolution, and an ever greater number of environmental variables to take into account. The management information process requires access to relevant documentation and source data. To support such demanding scenarios a promising approach is based on e-Infrastructures. By definition, an e-Infrastructure is a framework enabling secure, cost-effective and on-demand resource sharing across domain boundaries.The potentially unlimited availability of resources allows a new development paradigm based on the notion of Virtual Research Environment, i.e., an integrated environment that provides seamless access to resources and offers facilities for communication, collaboration and interaction among scientists and researchers. This presentation focuses on the implementation of this innovative approach in the context of D4Science.

D4SCIENCEII - Interoperability Solutions
Candela L, Kakaletris G, Pagano P
The realisation of a knowledge ecosystem requires the identification and deployment of a set of interoperability approaches and solutions making the interaction among the resources partaking to it feasible. The interoperability scenarios to be addressed depend on a set of factors including the type of resources involved, the kind of interaction to be realised, the technologies these resources have been implemented with. This deliverable describes a portfolio of standards (de jure or de facto), approaches and solutions that have been discussed and identified in the context of a working group operated by the D4Science-II project having as members representatives of the AquaMaps, D4Science, DRIVER, FAO, GENESI-DR and INSPIRE data infrastructures and resource providers. This working group surveyed the characteristics of the resources offered by each infrastructure as well as the standards and approaches put in place by them to "expose" their resources and simplify their consumption from third parties.Project(s): D4SCIENCE-II

This working group surveyed the characteristics of the resources offered by each infrastructure as well as the standards and approaches put in place by them to "expose" their resources and simplify their consumption from third parties.Project(s): D4SCIENCE-II

D4SCIENCE-II - Report on Scenario Specific Technology Development
Candela L, Kakaletris G, Papanikos G
D4Science II project aims to serve a set of different scientific communities under five (5) pre-identified scenarios, that consist of a set of users, applications and resources. In order for these scenarios to be realised on an interoperating eInfrastructures landscape, case-specific software implementation is required. This implementation is targeting (a) the migration or full implementation of applications that reside on the "outer" infrastructures in the new landscape and (b) the implementation of new functionality on gCube in order for the latter to cope with user requirements coming from NA5 tasks. The progress of the design and implementation of these components is being reported in this deliverable, which has the form of an on-line document produced by the processing of the thread of tickets managed in the TRAC system of the project that relate to the JRA2 tasksProject(s): D4SCIENCE-II
