DCAT Application Profile for European Data Portals
type: Group
alternative: DCAT-AP
comment: The DCAT Application profile for data portals in Europe (DCAT-AP) is a specification based on the Data Catalogue vocabulary (DCAT) for describing public sector datasets in Europe. Its basic use case is to enable cross-data portal search for data sets and make public sector data better searchable across borders and sectors. This can be achieved by the exchange of descriptions of datasets among data portals.

Quality Assurance and Content Description
type: Project
is funded by: http://eur-lex.europa.eu/legal-content/EN/ALL/
alternative: QUATRO
comment: The project aims at providing a common platform for quality labels making it possible for the many existing labelling schemes to be brought together through a single, coherent approach without affecting an individual scheme's assessment criteria or independence. The platform will support i) easy, flexible routes for content providers to add quality labels to their sites that are both ‘visible’ to humans and machines, ii) automatic validation of quality labels against a label operator's database, and iii) real-time probabilistic label verification. As well, the proposed platform will have direct applicability to content descriptions, classification and so-called “discovery metadata.”

abstract: GeoDCAT-AP is an extension of the “DCAT Application Profile for European Data Portals” (DCAT-AP) for describing geospatial datasets, dataset series, and services. It provides an RDF syntax binding for the union of metadata elements defined in the core profile of ISO 19115:2003 and those defined in the framework of the INSPIRE Directive. Its basic use case is to make spatial datasets, data series, and services searchable on general data portals, thereby making geospatial information better searchable across borders and sectors. This can be achieved by the exchange of descriptions of data sets among data portals.

abstract: DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. DCAT enables a publisher to describe datasets and data services in a catalog using a standard model and vocabulary that facilitates the consumption and aggregation of metadata from multiple catalogs. This can increase the discoverability of datasets and data services. It also makes it possible to have a decentralized approach to publishing data catalogs and makes federated search for datasets across catalogs in multiple sites possible using the same query mechanism and structure. Aggregated DCAT metadata can serve as a manifest file as part of the digital preservation process.

abstract: DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. Since its first release in 2014 as a W3C Recommendation, DCAT has seen a wide adoption across communities and domains, particularly in conjunction with implementing the FAIR data principles (for findable, accessible, interoperable and reusable data). These implementation experiences, besides demonstrating the fitness of DCAT to meet its intended purpose, helped identify existing issues and gaps. Moreover, over the last few years, additional requirements emerged in data catalogs, given the increasing practice of documenting not only datasets but also data services and APIs. This paper illustrates the new version of DCAT, explaining the rationale behind its main revisions and extensions, based on the collected use cases and requirements, and outlines the issues yet to be addressed in future versions of DCAT.

abstract: This scientific review paper aims at challenging a common point of view on metadata as a necessary evil and something mandatory to the data creating and dataset publishing process. Metadata are instead presented as a crucial element to ensure the findability of data services and repositories. This paper describes a way through four levels of metadata management and publication, from default unstructured data, through schema-based metadata with literal values and/or URIs, towards linked open (meta)data providing explicit linkage between reliable data resources. Such research was conducted within the European Union's project PoliVisu. Special attention is given to the following: (1) guidance on publication aimed at the broad audience of search engine users and (2) the publication of geo (meta)data not only via standard technologies, such as the OGC Catalogue Service for Web and open data portals, but also through leading search engines (that are Schema.org-based).

abstract: Enabling full interoperability within and between population-based patient- registry domains would open up access to a rich and unique source of health data for secondary data usage. Previous attempts to tackle patient-registry interoperability have met with varying degrees of success, but a unifying solution remains elusive. The purpose of this paper is to show by practical example how a solution is attainable via the implementation of an existing framework based of the concept of federated, semantic metadata registries. One important feature motivating the use of this framework is that it can be implemented gradually and independently within each patient-registry domain. By employing linked open data principles, the framework extends the ISO/IEC 11179 standard to provide both syntactic and semantic interoperability of data elements with the means of specifying automated extraction scripts for retrieval of data from different registry content models. The examples provided address the domain of European population-based cancer registries to demonstrate the feasibility of the approach. One of the examples shows how quick gains are derivable by allowing retrieval of aggregated core data sets. The other examples show how aggregated full sets of data and record-level data might also be retrieved from each local registry. An infrastructure of patient-registry domains adhering to the principles of the framework would provide the semantic contexts and inter-linkage of data necessary for automated search and retrieval of registry data. It would thereby also lay the foundation for making registry data serviceable to artificial intelligence (AI) applications.

abstract: Data owners are creating an ever richer set of information resources online, and these are being used for more and more applications. Spatial data on the Web is becoming ubiquitous and voluminous with the rapid growth of location-based services, spatial technologies, dynamic location-based data and services published by different organizations. However, the heterogeneity and the peculiarities of spatial data, such as the use of different coordinate reference systems, make it difficult for data users, Web applications, and services to discover, interpret and use the information in the large and distributed system that is the Web. To make spatial data more effectively available, this paper summarizes the work of the joint W3C/OGC Working Group on Spatial Data on the Web that identifies 14 best practices for publishing spatial data on the Web. The paper extends that work by presenting the identified challenges and rationale for selection of the recommended best practices, framed by the set of principles that guided the selection. It describes best practices that are employed to enable publishing, discovery and retrieving (querying) spatial data on the Web, and identifies some areas where a best practice has not yet emerged.

abstract: GeoDCAT-AP is an extension of the “DCAT Application Profile for European Data Portals” (DCAT-AP) for describing geospatial datasets, dataset series, and services. It provides an RDF syntax binding for the union of metadata elements defined in the core profile of ISO 19115:2003 and those defined in the framework of the INSPIRE Directive. Its basic use case is to make spatial datasets, data series, and services searchable on general data portals, thereby making geospatial information better searchable across borders and sectors. This can be achieved by the exchange of descriptions of data sets among data portals.

abstract: The transparency and reproducibility of scientific evidence underpinning policy is crucial to build and retain trust. This paper describes an application that takes a significant step towards enhanced transparency of scientific models used for policy making: The Modelling Inventory Database and Access Services (MIDAS) developed by the Joint Research Centre (JRC) describes models in use by the JRC in their scientific context by linking them to other models, to related data, to supported policies and to domain experts. To effectively share the resulting knowledge across different domains and with policy makers within the institution MIDAS represents the resulting complex network of relations and entities through visual aids based on visual analytics and data narratives. This paper describes not just the application in order to contribute to emerging dialogue on best practice for model documentation, it describes the process and main challenges we met with, and the approach taken to overcome them.

abstract: Scientific domains and the public sector increasingly open their data repositories. In June 2013, the G8 boosted the topic in a charter, and in April 2014, the Open Government Partnership welcomed its 64th partner to make governments more open and accountable. The U.S. and Australian governments, together with the European Commission, complement this initiative of the public sector with the Research Data Alliance, to ease research data sharing and exchange. Although many objectives are shared, we see different interpretations and developments all over the globe. This chapter highlights the central activities in the European context and anticipates possible developments. It explores the concept of a cross-domain open data ecosystem by (a) explaining the current situation, (b) exploring innovative approaches and recent trends on information and communication technologies, and (c) outlining potential pathways to couple public sector information and public-funded research data. The chapter concludes by summarizing practical implications and outlining directions for future research.

abstract: Collaborative tagging is one of the most popular services available online, and it allows end user to loosely classify either online or offline resources based on their feedback, expressed in the form of free-text labels (i.e., tags). Although tags are not per se sensitive information, the wide use of collaborative tagging services increases the risk of cross referencing, thereby seriously compromising user privacy. In this paper, we make a first contribution in this direction by showing how a specific privacy-enhancing technology, namely tag suppression, can be used to protect end-user privacy. Moreover, we analyze how our approach can affect the effectiveness of a policy-based collaborative tagging system which supports enhanced Web access functionalities, like content filtering and discovery, based on preferences specified by end users.

abstract: Recent years have seen an increasing diffusion of online communities giving their members the ability of specifying and sharing metadata concerning online resources. Such practice, also known as social or collaborative tagging, has the purpose of collecting and sharing opinions about Web resources and simplifying their retrieval. In this paper, we go one step further and show how tags can have more enhanced applications to be exploited for customizing Web content fruition. More precisely, we propose a multi-layer framework where data collected by social tagging communities are complemented with additional services. Such services provide users the ability of expressing their dis/agreement with existing tags, denoting the members they trust based on their characteristics and relationships, or specifying policies on which “quality” assessment of resources should be returned. Besides providing the formal specification of the proposed framework, we illustrate two case studies we have implemented and the experiments we have carried out in order to verify the feasibility of our approach.

abstract: The cultural, historic, and natural diversity in the European Union creates a fertile ground for both policies and innovation that aim at removing obstacles to the integration and interoperability of data on Europe’s natural environment. In fact, the sharing of resources across multiple information communities raises the need of new technologies that support resource discovery and (re-)use. The aim of this paper is to provide a better understanding of the issues related to semantic interoperability in the context of environmental data management in the European Union, and of measures and activities that are addressing these problems. It does so by providing the policy context, and by highlighting activities and best practices of selected EU-funded research projects and activities, especially in relation to Linked Open Data principles.

abstract: Web content filtering is a means to make end-users aware of the ‘quality’ of Web resources by evaluating their contents and/or characteristics against users' preferences. Although they can be used for a variety of purposes, Web content filtering tools are mainly deployed as a service for parental control purposes, and for regulating the access to Web content by users connected to the networks of enterprises, libraries, schools, etc. Current Web filtering tools are based on well established techniques, such as data mining and firewall blocking, and they typically cater to the filtering requirements of very specific end-user categories. Therefore, what is lacking is a unified filtering framework able to support all the possible application domains, and making it possible to enforce interoperability among the different filtering approaches and the systems based on them. In this paper, a multi-strategy approach is described, which integrates the available techniques and focuses on the use of metadata for rating and filtering Web information. Such an approach consists of a filtering meta-model, referred to as MFM (Multi-strategy Filtering Model), which provides a general representation of the Web content filtering domain, independently from its possible applications, and of two prototype implementations, partially carried out in the framework of the EU projects EUFORBIA and QUATRO, and designed for different application domains: user protection and Web quality assurance, respectively.

Such features give end users the ability of being aware of the “quality” of the resources they are accessing, based on the opinions of the members of their community, and of being informed whether such resources can be safely used, according to the requirements specified by end users themselves. Besides illustrating the main characteristics of the QSN and its architecture, we describe its prototype implementation, carried out in the framework of the QUATRO Plus EU project, and its application to a use case scenario, involving groups of teenagers from three different European countries, acting as Youth Panels of the Safer Internet EU Programme.

Differently from traditional access control systems, our mechanism makes use of a semi-decentralized architecture, where access control enforcement is carried out client-side. Access to a resource is granted when the requestor is able to demonstrate of being authorized to do that, by providing a proof. In the paper, besides illustrating the main notions on which our access control model relies, we present all the protocols underlying our system and a performance study of the implemented prototype.

This document describes how sets of IRIs can be defined such that descriptions or other data can be applied to the resources obtained by dereferencing IRIs that are elements of the set. IRI sets are defined as XML elements with relatively loose operational semantics. This is underpinned by the formal semantics of POWDER which include a semantic extension, defined separately. A GRDDL transform is associated with the POWDER namespace that maps the operational to the formal semantics.

abstract: The original purpose of Web metadata was to protect end-users from possible harmful content and to simplify search and retrieval. However they can also be exploited in more enhanced applications, such as Web access personalization on the basis of end-users' preferences. In order to achieve this, it is however necessary to address several issues. One of the most relevant is how to assess the trustworthiness of Web metadata. In this paper, we discuss how such issue can be addressed through the use of collaborative and Semantic Web technologies. The system we propose is based on a Web-based Social Network, where members are able not only to specify labels, but also to rate existing labels. Both labels and ratings are then used to assess the trustworthiness of resources' descriptions and to enforce Web access personalization.

abstract: The wide diffusion and usage of social networking Web sites in the last years have made publicly available a huge amount of possible sensitive information, which can be used by third-parties with purposes different from the ones of the owners of such information. Currently, this issue has been addressed by enforcing into Web-based Social Networks (WBSNs) very simple protection mechanisms, or by using anonymization techniques, thanks to which it is possible to hide the identity of WBSN members while performing analysis on social network data. However, we believe that further solutions are needed, to allow WBSN members themselves to decide who can access their personal information and resources. To cope with this issue, in this article we illustrate a decentralized security framework for WBSNs, which provide both access control and privacy protection mechanisms. In our system, WBSN members can denote who is authorized to access the resources they publish and the relationships they participate in, in terms of the type, depth, and trust level of the relationships existing between members of a WBSN. Cryptographic techniques are then used to provide a controlled sharing of resources while preserving relationship privacy.

abstract: Web-based social networks (WBSNs) are online communities that allow users to publish resources (e.g., personal data, annotations, blogs) and to establish relationships, possibly of a different type (“friend,” “colleague,” etc.) for purposes that may concern business, entertainment, religion, dating, and so forth. In the last few years, the usage and diffusion of WBSNs has been increasing, with about 300 Web sites collecting the information of more than 400 million registered users. As a result, the “net model” is today used more and more to communicate, share information, make decisions, and ‘do business’ by companies and organizations. Regardless of the purpose of a WBSN, one of the main reasons for participating in social networking is to share and exchange information with other users. Recently, thanks to the adoption of Semantic Web technologies such as FOAF and other RDF-based vocabularies, accessing and disseminating information over multiple WBSNs has been made simpler. If this has been quite a relevant improvement towards an easier sharing of information, it makes more urgent that content owners have control over information access. In fact, making available possibly sensitive and private data and resources implies that they can be used by third parties for purposes different from the intended ones. As a matter of fact, users’ personal data and resources are regularly exploited not only by companies for marketing purposes, but also by governments and institutions for tracking persons’ behaviors and opinions, and in the worst case, by online predators. It is then a challenging issue to devise security mechanisms for social networks, able to protect private information and regulate access to shared resources. In this article, besides providing an overview of the characteristics of the WBSN environment and its protection requirements, we illustrate the current approaches and future trends to social network security, with particular attention paid to the emergin…

abstract: In this paper we present CoCoMA, an integrated platform, developed in the framework of the DELOS II European Network of Excellence on Digital Libraries, aiming at the unification of the most important aspects of multimedia management and multimedia presentation. The paramount goal of CoCoMA is to maximize the added value from task and data integration by the identification and exploitation of connection points and inherent workflow similarities. The paper provides a brief description of the involved research fields, suggests an architecture for integrated multimedia consumption and presentation, and discusses the most prominent connection points. Problems and solutions are discussed jointly, and illustrated by the components of the application prototype developed for the DELOS project.

abstract: In this chapter, besides discussing the current strategies for Web content filtering, outlining their advantages and drawbacks, we present an approach, formerly developed in the framework of the EU project EUFORBIA, which, besides addressing the main drawbacks of the existing systems, can be applied for purposes comprising both users’ protection and quality assurance. The main features of such an approach are the support for multiple metadata vocabularies for the rating and filtering of Web resources, and the possibility of specifying policies which allow the system to decide whether a resource is appropriate or not for a given user based on his/her preferences and characteristics.

abstract: Current social networks implement very simple protection mechanisms, according to which a user can state whether his/her personal data, relationships, and resources should be either public or accessible only by him/herself (or, at most, by users with whom he/she has a direct relationship). This is not enough, in that there is the need of more flexible mechanisms, making a user able to decide which network participants are authorized to access his/her resources and personal information. With this aim, in a previous paper we have proposed an access control model where authorized users are denoted based on the relationships they participate in. Nonetheless, we believe that this is just a first step towards a more comprehensive privacy framework for social networks. Indeed, besides users' resources and personal data, also users' relationships may convey sensitive information. For this reason, in this paper we focus on relationship protection, by proposing a strategy exploiting cryptographic techniques to enforce a selective dissemination of information concerning relationships across a social network.

abstract: We present in this paper an integrated system that allows the management and annotation of multimedia objects stored in MPEG-7/21 repositories, and the specification and semi-automatic generation of multimedia presentations based on the content relationships that exist between the multimedia objects. This system is the outcome of the collaboration between the Technical University of Crete (TUC-MUSIC) and the University of Milan (UNIMI) in the CoCoMA project of the DELOS II European Network of Excellence on Digital Libraries. The resulting system is one of the main components of the CoCoMA infrastructure that aims to provide content- and context-aware rich interactive multimedia presentations by controlling data fusion and metadata reuse. The integrated system utilizes the SyMPA management and presentation authoring system developed by UNIMI and the DS-MIRF framework developed by TUC-MUSIC.

abstract: Web-based social networks (WBSNs) are online communities where participants can establish relationships and share resources across the Web with other users. In recent years, several WBSNs have been adopting Semantic Web technologies, such as FOAF, for representing users' data and relationships, making it possible to enforce information interchange across multiple WBSNs. Despite its advantages in terms of information diffusion, this raised the need of giving content owners more control on the distribution of their resources, which may be accessed by a community far wider than they expected. In this paper, we present an access control model for WBSNs, where policies are expressed as constraints on the type, depth, and trust level of existing relationships. Relevant features of our model are the use of certificates for granting relationships' authenticity, and the client-side enforcement of access control according to a rule-based approach, where a subject requesting to access an object must demonstrate that it has the rights of doing that.

abstract: The need to filter online information in order to protect users from possible harmful content can be considered as one of the most compelling social issues derived from the transformation of the Web into a public information space. Despite that Web rating and filtering systems have been developed and made publicly available quite early, no effective approach has been established so far, due to the inadequacy of the proposed solutions. Web filtering is then a challenging research area, needing the definition and enforcement of new strategies, considering both the current limitations and the future developments of Web technologies—in particular, the upcoming Semantic Web. In this chapter, we provide an overview of how Web filtering issues have been addressed by the available systems, bringing in relief both their advantages and shortcomings, and outlining future trends. As an example of how a more accurate and flexible filtering can be enforced, we devote the second part of this chapter to describing a multi-strategy approach, of which the main characteristics are the integration of both list- and metadata-based techniques and the adoption of sophisticated metadata schemes (e.g., conceptual hierarchies and ontologies) for describing both users' characteristics and Web pages content.

abstract: This paper illustrates some of the Semantic Web techniques used in the framework of the EU project EUFORBIA, which deals with the rating and filtering of ‘questionable’ Web sites concerned with racism, violence, pornography, etc. The rationale for using a high-level semantic approach in this domain is linked with the assumption that an in-depth description of the ‘semantic content’ of Web sites should allow the implementation of filtering strategies more flexible, accurate and (neatly) sophisticated than the current ones. From a technical point of view, the final result of the project consists of two integrated prototypes that communicate through a common ontology.

abstract: Synchronized multimedia applications play an important role in a Digital Library environment, since they allow one to efficiently disseminate knowledge among differently skilled users through an approach which is more direct than the classic ‘static’ documents. In this paper, we propose a new authoring approach based on an innovative presentation structure and a new class of contentbased constraints. Thanks to a flexible heuristic process, such features allow the author to easily combine several multimedia objects into a multi-topic presentation, whose different contents can be freely chosen by end users according to their preferences or skills.

abstract: Digital Libraries (DLs) introduce several challenging requirements with respect to the formulation, specification and enforcement of adequate access control policies. Unlike conventional database environments, a DL typically is characterised by a dynamic subject population, often making accesses from remote locations, and by an extraordinarily large amount of information, stored in a variety of formats. Additionally, protecting a DL does not only means protecting documents that reside at the DL site, but also protecting accesses that the DL subscribers made to external Web documents. In this paper we present MaΧ, a comprehensive system for enforcing access control, specifically tailored to both DL and Web environments. Key features of MaΧ are the support for credential and content-based access control to DL and Web documents, and its full integration with standard Internet rating systems.
