Ubiquitous home healthcare systems have been playing an increasingly significant role in the treatment and management of chronic diseases, such as diabetes and hypertension, but progress has been hampered by the lack of standardization in the exchange of medical health care information. In an effort to establish standardization, this paper proposes a home healthcare monitoring system data exchange scheme between the HL7 standard and the IEEE1451 standard. IEEE1451 is a standard for special sensor networks, such as industrial control and smart homes, and defines a suite of interfaces that communicate among heterogeneous networks. HL7 is the standard for medical information exchange among medical organizations and medical personnel. While it provides a flexible data exchange in health care domains, it does not provide for data exchange with sensors. Thus, it is necessary to develop a data exchange schema to convert data between the HL7 and the IEEE1451 standard. This paper proposes a schema that can exchange data between HL7 devices and the monitoring device, and conforms to the IEEE 1451 standard. The experimental results and conclusions of this approach are presented and show the feasibility of the proposed exchange schema.

This Request for Comments (RFC) suggests a framework for the description, exchange and interlinking of Synthetic Biology data. The framework would create an open process for the evolution and “rolling” standardization of data models. It describes how data and data models are to be published, how they are exchanged and integrated between different parties, and how they can be extended, corrected and interlinked in a decentralized fashion. These goals are achieved by embracing the RDF (Resource Description Framework), a set of W3C standards. A one-sentence summary of this proposal would there- fore be: “Use RDF according to the W3C standards.” The PoBoL pro ject (Provisional BioBrick Ontology Language, http://pobol.org) is based on this idea. This RFC does not describe a data model per se but only outlines a possible architecture and rules of data exchange.

peer-reviewed; Localisation is a relatively new field, one that is constantly changing with the latest technology to offer services that are cheaper, faster and of higher quality. As the complexity of localisation projects increases, interoperability between different localisation tools and technologies becomes ever more important. However, lack of interoperability is a significant problem in localisation. One important aspect of interoperability in localisation is the lossless exchange of data between different technologies and different stages of the overall process. Standards play a key role in enabling interoperability. Several standards exist that address data-exchange interoperability. The XML Localisation Interchange File Format (XLIFF) has been developed by a Technical Committee of Organization for the Advancement of Structured Information Standards (OASIS) and is an important standard for enabling interoperability in the localisation domain. It aims to enable the lossless exchange of localisation data and metadata between different technologies. With increased adoption, XLIFF is maturing. Solutions to significant issues relating to the current version of the XLIFF standard and its adoption are being proposed in the context of the development of XLIFF version 2. Important matters for a successful adoption of the standard...

This research estimates the impact of macroeconomic fluctuations on import protection policies over 1988:Q1-2010:Q4 for the United States, European Union, and three other industrialized economies. First, estimates on a pre-Great Recession sample provide evidence of three key relationships for the US and EU. Increases in domestic unemployment rates and real appreciations in bilateral exchange rates led to substantial increases in antidumping and related forms of import protection. Furthermore, economies historically imposed these bilateral import restrictions on trading partners going through their own periods of weak economic growth. Second, estimates from the pre-Great Recession model predict a major trade policy response during 2008:Q4-2010:Q4, given the realized macroeconomic shocks. New US and EU trade barriers were projected to cover up to an additional 15 percentage points of nonoil imports, well above the baseline level of 2-3 percent of import coverage immediately preceding the crisis. Third, re-estimating the model on data from the Great Recession period illustrates why the realized trade policy response differed from model predictions based on historical data. While exchange rate movements played an important role in limiting new import protection...

Utilization of XML techniques is seen as a necessary step towards more powerful ways of incorporating semantics into data exchange used by heterogeneous systems. In this paper various techniques are studied and tried, such as XSL transformations (XSLT) and ways of extending the contents of XML Schemas, the final aim being in creating an understanding of the possibilities, and a roadmap that could possibly lead to some useful real-world applications. Based on a materials database an XML Schema is specified that defines the structure of an XML document capable of representing quite complex materials test data together with mandatory metadata. Some approaches are discussed and some of them implemented in prototypes to study the possibilities to comply with and use MatML in order to support sharing of experimentally measured materials data.; JRC.F.4-Safety of future nuclear reactors

The book gives an overview of the needs and perspectives of environmental data exchange in the inland water area. It consists of 3 sections: Data Exchange The EDEN-IW Project Policy Issues and Data Harmonisation The perspectives and the visions of the needs are that a citizen or a user, including policy makers, needs be able to get rapid answers to environmental questions on inland waters, without any knowledge about what data sources might be available or how to connect to them. The questions may range from global to continental, from national to local, following political boundaries, or catchment areas as required. In principle, a large number of existing inland water databases in the world could be linked together, providing citizens with access to a world wide inland water database, together with tools to assess the information and regulate the inland water environment in a more efficient and effective way than in the current situation. Starting from these needs and technological challenges, Part 1 of the book examines data exchange issues and previous solutions. This starts from the examination of two examples of data exchange systems, one national and one European, and continues with the examination of technologies of interest both in terms of software agents...

This article gives an overall introduction to the book: Environmental Data Exchange Network for Inland Water. In a world where computing power, storage capacity and network size all tend to grow exponentially, exchange of data is growing at a similar rate. From a purely informationtechnology point of view, any data packet sent over the network is exchange of data, and is thus linked to the overall network traffic. Searching the Web for relevant information has become commonplace; indeed, it is at times difficult to imagine how cumbersome the search for information was before the World Wide Web. It is amazing to see the ease with which it is now possible to search for and find, for instance, telephone numbers, addresses, flight information and scientific publications (just to mention a few). However, for other types of data, the search is more difficult and has yet to realise the full potential of the full data exchange. On the philosophical level, one could speculate that the exchange of document information through the World Wide Web has been so successful due to the fact that the HyperText Markup language (HTML) was invented at the same time as the first browsers became operational and that the protocol and the language were so simple and easy to use. For data held in databases...

The web-enabled materials properties database MatDB of the European Commission Joint Research Centre (EC-JRC) is a database application for the storage, retrieval and evaluation of experimentally measured materials data coming from European R&D projects. Data exchange and interoperability are important database issues to reduce costs of expensive material tests. Many organizations world-wide are participating in the development of GEN IV reactors. To reduce costs the GEN IV International Forum has agreed to interoperate and exchange data for the screening and qualification of candidate materials. To simplify the complexity of data mapping between differently structured databases, adoption of a standardized XML schema is the favored option. The paper focuses on MatDB XML related tools and items: • Upgrade, extension and implementation of the MatDB XML schema within a planned US/EC cooperation; • European standardization activities for data exchange, interoperability and the development of standard formats for engineering materials data; • MatDB data cite participation.; JRC.F.4-Nuclear Reactor Integrity Assessment and Knowledge Management

One of the JRC Petten tasks is to support European Research and Development (R&D) projects in the material and energy related areas with the management and dissemination of research results. By using XML technology test data can be entered directly from the test machines into the Web-enabled 'Materials Database' (Mat-DB), which is an integral part of the On-line Data Information Network (ODIN On-line Data Information Network, 2004) that has been developed at JRC Petten. Test data, which are kept in XML format and sent by R&D project partners via the World Wide Web to the Petten Server are stored within the Mat-DB XML module. There they can be checked and updated on-line before they are uploaded into the database. After validation by the source administrator they can immediately be retrieved and evaluated by all project partners. A pilot test with the new XML related data exchange module from test machine into Mat-DB has currently been started within the European 'TMF Standard' R&D project.; JRC.F.4-Nuclear design safety

A long empirical literature has examined the idea that, in the absence of hedging mechanisms, currency risk should have an adverse effect on the export volumes of risk averse exporters. But there are no clear conclusions from this literature, and the current consensus seems to be that there is at most a weak negative effect of exchange rate volatility on aggregate trade flows. However, most of this literature examines the impact of exchange rate volatility on aggregate trade flows, implicitly assuming a uniform impact of this volatility on exporters across sectors. This paper explots the fact that, if exchange rate volatility is detrimental for trade, firms exporting goods that offer a natural hedge against exchange rate fluctuations -- i.e. those whose international price is negatively correlated with the nominal exchange rate of the country where they operate -- should be relatively benefited in environments of high exchange rate volatility, and capture a larger share of the country's export basket. This hypothesis is tested using detailed data on the composition of trade of 132 countries at 4-digit SITC level. The results show that the commodities that offer natural hedge capture a larger share of a country's export basket when the exchange rate is volatile...

This paper estimates how changes in China's exchange rates would affect exports from competitor countries in third-country markets -- in other words, the "spillover effect." The authors use recent theory to develop an identification strategy, with a key role for the competition between China and its developing country competitors in specific products and export destinations. Using disaggregated trade data, they estimate the spillover effect by exploiting the variation across different exporters, importers, products, and time periods. They find a spillover effect that is statistically and quantitatively significant. Their estimates suggest that a 10-percent appreciation of China's real exchange rate boosts a developing country's exports of a typical four-digit Harmonized System product category to third markets by about 1.5 to 2 percent on average. The magnitude of the spillover effect varies systematically with the characteristics of products, such as the extent to which they are differentiated.

Disconnected cancer research data management and lack of information exchange about planned and ongoing research are complicating the utilisation of internationally collected medical information for improving cancer patient care. Rapidly collecting/pooling data can accelerate translational research in radiation therapy and oncology. The exchange of study data is one of the fundamental principles behind data aggregation and data mining. The possibilities of reproducing the original study results, performing further analyses on existing research data to generate new hypotheses or developing computational models to support medical decisions (e.g. risk/benefit analysis of treatment options) represent just a fraction of the potential benefits of medical data-pooling. Distributed machine learning and knowledge exchange from federated databases can be considered as one beyond other attractive approaches for knowledge generation within “Big Data”. Data interoperability between research institutions should be the major concern behind a wider collaboration. Information captured in electronic patient records (EPRs) and study case report forms (eCRFs), linked together with medical imaging and treatment planning data, are deemed to be fundamental elements for large multi-centre studies in the field of radiation therapy and oncology. To fully utilise the captured medical information...

We consider the problem of finding the minimum sum-rate strategy in cooperative data exchange systems that do not allow packet-splitting (NPS-CDE). In an NPS-CDE system, there are a number of geographically close cooperative clients who send packets to help the others recover a packet set. A minimum sum-rate strategy is the strategy that achieves universal recovery (the situation when all the clients recover the whole packet set) with the the minimal sum-rate (the total number of transmissions). We propose an iterative merging (IM) algorithm that recursively merges client sets based on a lower estimate of the minimum sum-rate and updates to the value of the minimum sum-rate. We also show that a minimum sum-rate strategy can be learned by allocating rates for the local recovery in each merged client set in the IM algorithm. We run an experiment to show that the complexity of the IM algorithm is lower than that of the existing deterministic algorithm when the number of clients is lower than $94$.; Comment: 9 pages, 3 figures

In a data exchange setting with target constraints, it is often the case that a given source instance has no solutions. In such cases, the semantics of target queries trivialize. The aim of this paper is to introduce and explore a new framework that gives meaningful semantics in such cases by using the notion of exchange-repairs. Informally, an exchange-repair of a source instance is another source instance that differs minimally from the first, but has a solution. Exchange-repairs give rise to a natural notion of exchange-repair certain answers (XR-certain answers) for target queries. We show that for schema mappings specified by source-to-target GAV dependencies and target equality-generating dependencies (egds), the XR-certain answers of a target conjunctive query can be rewritten as the consistent answers (in the sense of standard database repairs) of a union of conjunctive queries over the source schema with respect to a set of egds over the source schema, making it possible to use a consistent query-answering system to compute XR-certain answers in data exchange. We then examine the general case of schema mappings specified by source-to-target GLAV constraints, a weakly acyclic set of target tgds and a set of target egds. The main result asserts that...

We consider the "coded cooperative data exchange problem" for general graphs. In this problem, given a graph G=(V,E) representing clients in a broadcast network, each of which initially hold a (not necessarily disjoint) set of information packets; one wishes to design a communication scheme in which eventually all clients will hold all the packets of the network. Communication is performed in rounds, where in each round a single client broadcasts a single (possibly encoded) information packet to its neighbors in G. The objective is to design a broadcast scheme that satisfies all clients with the minimum number of broadcast rounds. The coded cooperative data exchange problem has seen significant research over the last few years; mostly when the graph G is the complete broadcast graph in which each client is adjacent to all other clients in the network, but also on general topologies, both in the fractional and integral setting. In this work we focus on the integral setting in general undirected topologies G. We tie the data exchange problem on G to certain well studied combinatorial properties of G and in such show that solving the problem exactly or even approximately within a multiplicative factor of \log{|V|} is intractable (i.e....

Purpose. To obtain the interference immunity of the data exchange by spread spectrum signals with variable entropy of the telemetric information data exchange with autonomous mobile robots. Methodology. The results have been obtained by the theoretical investigations and have been confirmed by the modeling experiments. Findings. The interference immunity in form of dependence of bit error probability on normalized signal/noise ratio of the data exchange by spread spectrum signals with variable entropy has been obtained.It has been proved that the interference immunity factor (needed normalized signal/noise ratio) is at least 2 dB better under condition of equal time complexity as compared with correlation processing methods of orthogonal signals. Originality. For the first time the interference immunity in form of dependence of bit error probability on normalized signal/noise ratio of the data exchange by spread spectrum signals with variable entropy has been obtained. Practical value. The obtained results prove the feasibility of using variable entropy spread spectrum signals data exchange method in the distributed telemetric information processing systems in specific circumstances.; Comment: in Ukrainian

The Consultative Group on International Agricultural Research (CGIAR; http://www.cgiar.org/) centres have developed the International Crop Information System (ICIS; http://www.icis.cgiar.org) for the management and integration of global information on genetic resources, and germplasm improvement for any crop. The Maize breeding programs at CIMMYT (http://beta.cimmyt.org/) have different software tools to manage phenotypic, genotypic, and environmental information for their experiments generated worldwide. These tools have the capacity of collecting information in the field, wet lab, and store it into different relational databases. The IMIS (http://imis.cimmyt.org/confluence/display/IMIS/Crop+Finder) is an implementation of the ICIS, which is a computerized database system for general, integrated management and utilization of genealogy, nomenclature, genetic, phenotypic and characterization data for maize. Data exchange within and between databases as well as retrieving information are often hampered by the variability of terms used to describe comparable objects. To overcome this problem, the Crop Ontology (CO) database (http://cropontology.org/) is developed. It provides controlled vocabulary sets for several economically important plant species and facilitates biocurators working in genebanks of plant genetic resources (PGR) and crop breeding data curation and annotation. The maize trait ontology is developed as one of subclasses of CO trait ontology providing standardized trait descriptions...

Presented at the CRIS2012 Conference in Prague.-- 10 pages.-- Full conference programme available at: http://www.cris2012.org/findByFilter.do?categoryId=1158; This paper outlines the approach of the CERIFy project, which involved engagement with four UK universities and one commercial company, and which can be usefully applied to institutions / organisations / companies who are working in the area of Research Information Management (RIM) and Current Research Information Systems (CRISs) to demonstrate the use of CERIF in ways which are immediately meaningful to the institutional research information manager or end-user. The CERIFy methodology puts the ‘user’ at the heart of system development and data exchange by using Business Process Analysis. The results can be used to facilitate data exchange / interoperation with systems and to assist with the procurement / development / modification / improvement of a CERIF-based CRIS system. We believe that the CERIFy approach offers an accessible, transferrable and scalable way for organisations to develop local knowledge and experience of the interoperation between their own systems and data, and the CERIF data model. CERIFy provides concrete examples of how the approach facilitated the data modelling of improved (standardised and integrated) RIM processes such as Indicators of Esteem and a bi-directional data exchange process of CRIS-based institutional data with an external commercial system (Thomson Reuters InCites) using CERIF-XML.

Presented at the CRIS2012 Conference in Prague, Session "IDs, Disambiguation, Interoperation".-- 10 pages.-- Contains: Conference paper (PDF) + presentation.; This paper received the CRIS 2012 Max Stempfhuber Award, http://bit.ly/1dqfYO5; The Common European Research Information Format (CERIF) is an established standard for Current Research Information Systems (CRISs) facing the increasing need for information sharing and exchange. euroCRIS released the first official CERIF XML exchange format in 2007; it followed the structure of the relational data model. Based on experience with the format and consulting with the CRIS community on newer interoperation and exchange concepts, the authors proposed an update to the CERIF XML exchange format. This updated CERIF XML aimed at compactness with expression and backwards compatibility. With this article, we provide insight into the motivation for change, present the updated format, and finally outline possible next steps.

Presented at the CRIS2002 Conference in Kassel.-- 7 pages.-- Contains: Conference paper (PDF) + PPT presentation.; In this paper a new flexible extensible XML-model for the exchange of research documentation is proposed, and a working XML-exchange model is described. The working model is limited to documentation produced by researchers. The ideas, XML-model and construction proposed and used in the working model are extensible, and can be expanded to the whole field of research documentation, and to other fields as well.; The paper is partly based on a report to be completed in May 2002. That report will provide a full description of the model, which is not possible in a short paper presented at the CRIS2002 Conference. The report aims to set out the groundwork and facts, to document the proposed newXML-exchange model, and to contribute to the further discussion in euroCRIS in respect of data exchange between different systems.
