The users must be able to trust these services, otherwise they will be reluctant to embrace the new opportunities and will not be able to reap the potential benefits. In addition, the end users wish to use the e-services in the simplest way possible and to have them ldquoon taprdquo 24times7 as other conventional utilities. For this to become possible, a robust interoperability fabric among the involved institutions needs to be established. This means having a lot of collaborative interactions invisible to the end-user (a business or an individual citizen) in order to fulfill the promise of e-services. Such interactions become more complex when the organizations belong to different countries, act according different laws in different languages. This paper presents the work being done to create an efficient, secure and trusted interoperability framework for public sector agencies of European Union member countries.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134068973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This experiment was motivated by the emergence of new digital media technology supporting uncompressed high-definition video capture, transport and display as well as the networking services required for its deployment across wide distances. The participating institutes have designed a distributed collaborative environment centered around the new technology and applied it to join the five sites into a single virtual classroom where a real course has been offered to the registered students. Here we are presenting the technologies utilized in the experiment, the results of a technology evaluation done with the help of the participating students and we identify areas of future improvements of the system. While there are a few hurdles in the path of successfully deploying this technology on a large scale, our experiment shows that the new technology is sustainable and the significant quality improvements brought by it can help build an effective distributed and collaborative classroom environment.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127392682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notwithstanding the ever increasing potential of innovative software and network technologies, collaborative working environments still require advanced solutions to effectively managing their inherent complexity, thereby boosting productivity and creativity. Essential components of innovative service-based collaborative working environments are collaboration-aware services that embed the required point-to-point or multi-point interaction patterns to support the flexible orchestration of distributed and concurrent activities. This paper introduces an approach that attempts to overcome the above mentioned drawbacks of current collaborative working environments by exploiting the precepts recently introduced by model-driven development and MDA (model driven architecture). The proposed approach is guided by a model transformation framework that makes use of the set of MDA-related standards (MOF, QVT and XMI) to obtain a high degree of automation, so that interoperable model transformation services can be implemented in a timely and efficient way. At the end, the single tool usually operated by a given worker can be considered as a virtual collaborative platform for creating and automatically transforming models of different types and at various levels of abstraction.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127266108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Policies can be a key component in deciding what and how much to reveal in the discovery stage for both information seekers and providers. Policies can also drive the process of negotiation in the acquisition and release stage. Policies are needed to monitor and enforce usage control as well as for auditing and accountability. Fine-grained policy integration algorithms are needed to support dynamic coalitions and virtual organizations that need to quickly share and integrate information. Policies must adapt, based on events and contexts, to support continuous access to critical information resources. Enforcement mechanisms are also needed to allow different parties to take joint decisions about data accesses. In this talk, we will first discuss the various policies that are relevant in the context of secure information sharing across collaborating organizations. We will then focus on tools for policy similarity analysis, focusing on the case of policies expressed in XACML, and then we will present a reference architecture for collaborative enforcement of access control policies.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121754768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peer2Schedule was built on top of the Peer2Me framework that provides management of mobile ad hoc networks over Bluetooth. The goal of the Peer2Schedule project can be divided into three main areas. 1) To develop a collaborative peer-to-peer application to evaluate the usefulness of such applications; 2) to evaluate the technical limitations of J2ME and Bluetooth in this domain; and 3) to implement and evaluate a mobile application to improve present ad-hoc collaboration. In this paper we also investigates the social and network issues related to such applications. Our findings indicates that Bluetooth and J2ME are useful technology to implement such applications, but the long time to establish connections and security issues in Bluetooth reduce the usability of such applications. In addition, it is essential that collaborative peer-to-peer applications must be developed as open source projects, to allow the users of such applications to evaluate the source code to assess how the application handles privacy. Finally, the paper elaborates on how the problem domain affects how the control-flow is managed in peer-to-peer applications.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121841364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
