Contribution: It is shown that the development platform integrated by the solidity language, Azure cloud blockchain, the Visual Studio .Net IDE and the SQL Server database manager allowed to design and build a blockchain workbench platform easily exploitable by companies to validate their processes and generate transparency in the handling of their information.

JavaScript Object Notation (JSON) data serialization for IFC schema in web-based BIM data exchange

Abstract In the building industry, building data such as objects and processes are described in Industry Foundation Classes (IFC) data model schema to support a neutral data exchange format for BIM tools interoperability. While IFC specification has been encoded in ifcXML format by buildingSMART to support XML-based data transmission, there is a lack of studies on the implementation of IFC specification using JavaScript Object Notation (JSON) serialization. JSON is a key-value style lightweight data exchange format that has higher parsing efficiency than XML and due to the inadequacies of XML, JSON has been widely used in Web applications, specifically in Asynchronous JavaScript and XML (AJAX) Web services. This paper highlights the need for JSON implementation of IFC specification and introduces ifcJSON Schema and its data content. The main objective of this study is to outline how IFC specification can be represented in JSON format. Therefore, the study explains the implementation of the IFC standard as a JSON schema to guide the creation of JSON documents. The ifcJSON documents can be used for web-based data transfer as an alternative to XML documents. Since current IFC specification release is IFC4 Add1, the implementation of ifcJSON4 schema is specified and guidelines for generating and validating ifcJSON documents are described. Additionally, this paper implements ifcJSON4 schema in a use case within the precast concrete domain by indicating the data content for a precast building element with its corresponding geometry representation, product placement, and owner history data. The analysis of results indicates that ifcJSON4 schema developed in this paper is a valid JSON schema that can guide the creation of valid ifcJSON documents to be used for web-based data transfer and to improve interoperability of Cloud-based BIM applications.

A novel and secure IoT based cloud centric architecture to perform predictive analysis of users activities in sustainable health centres

Diabetes, blood pressure, heart, and kidney, some of the diseases common across the world, are termed ’silent killers’. More than 50 % of the world’s population are affected by these diseases. If suitable steps are not taken during the early stages then severe complications occur from these diseases. In the work proposed, we have discussed the manner in which the Internet-of-Things based Cloud centric architecture is used for predictive analysis of physical activities of the users in sustainable health centers. The architecture proposed is based on the embedded sensors of the equipment rather than using wearable sensors or Smartphone sensors to store the value of the basic health-related parameters. Cloud centric architecture is composed of a Cloud data center, Public cloud, Private cloud, and uses the XML Web services for secure and fast communication of information. The architecture proposed here is evaluated for its adoption, prediction analysis of physical activities, efficiency, and security. From the results obtained it can be seen that the overall response between the local database server and Cloud data center remains almost constant with the rise in the number of users. For prediction analysis, If the results collected in real time for the analysis of physical activities exceed any of the parameter limits of the defined threshold value then an alert is sent to the health care personnel. Security analysis also shows the effective encryption and decryption of information. The architecture presented is effective and reduces the proliferation of information. It is also suggested, that a person suffering from any of the diseases mentioned above can defer the onset of complications by doing regular physical activities.

Standard Interfaces for Open Source Infrastructure as a Service Platforms

IntroductionCloud Computing is an already established technology, already having lost its aura as one of the hottest and most rapid developing topics in the industry. At the base of its services stack, Infrastructure as a Service (IaaS) model utilizes well understood architectures, providing access, mostly, to the same type of computing and storage resources across all platform providers. New topics entered the spotlight, such as integrated management of IaaS platforms, selection of an IaaS platform, vendor lock-in, interoperability and identity in the Cloud and efforts were made to address them by defining and using standardized interfaces. Standard data models and technologies compatible with both the IaaS platforms and the existing Internet Infrastructure had to be used. This led to adoption of established standards and technologies such as XML web services or JSON over RESTful services.2 Open Cloud Computing InterfaceOpen Cloud Computing Interface (OCCI) is a collection of community generated open specifications built through Open Grid Forum [1]. Intended to be an open and interoperable RESTful protocol and an API for all cloudrelated management activities, it started with a focus on the Infrastructure-as-a-Service layer but later extended to include all the other layers in the Cloud stack.The specifications are broken into several modules in order to achieve a greater flexibility and extensibility. Separate modules describe· the core models, defines an abstract representation of real-world resources intended to be manipulated through OCCI renderings [1].· the rendering of the code model using HTTP/REST, describes the interactions available for an OCCI implementation with the resources built using the core models [2].· the extensions to the code models specific to implementation of an Infrastructure as a Service API [3], defining its parameters for compute, storage and network.The main reasons behind the development of OCCI were identified in [4] and [5] as:· Interoperability, demanding a standardized API and protocol.· Integration, allowing different service providers to bring together and interconnect platforms based on different technologies.· Portability, providing standardized data formats understood by different providers, allowing porting between them.· Innovation, considering that established standards can be a driver for innovation.· Reusability, Figure 1, working on two levels, first allowing reuse of code through basic standardized APIs and, second, promoting reuse of standards in different technology fields.3 Cloud Data Management InterfaceCloud Data Management Interface (CDMI) describes a functional interface allowing applications to create, retrieve, update and delete data elements from the Cloud [6]. The standard is developed by SNIA, a global organization of storage solution providers. Using a CDMI compatible interface, cloud data consumers are able to discover the storage features offered by IaaS platforms. Along with data elements, the standard also allows the management of containers, accounts and retrieval of monitoring and billing information, Figure 2.CDMI is not designed to replace other object access protocols but to complement them. The standard uses RESTful protocol for building its interfaces, to keep it as simple as possible and to encourage its adoption. Adding discovery functions, it allows future extensions to the standard without breaking client compatibility.CDMI serves as both a storage protocol while, at the same time, offering a layer of client to cloud management and cloud to cloud standardized interactions. Clients can manage credentials to domains defined in the cloud forming a hierarchical structure that have objects attached to them and building a path for accessing and controlling these objects. For cloud to cloud interaction it introduces globally unique identifiers linked to objects for the whole of their lifetime to persist their identity if moved or replicated between clouds. …

Open source REST services for environmental sensor networking

The greatest challenge in the implementation of environmental sensing networks is converting a large variety of data streams from diverse sensors, often in proprietary protocols, to international standards such as Extensible Markup Language (XML) with Open Geospatial Consortium (OGC) XML tagging and web service standards. Implementing standards throughout the architecture will not only enable interoperability and reduce cost but will allow scientists to contribute to sensor network innovation. This article introduces open source Representational State Transfer (REST) services created specifically for environmental monitoring. OGC standards are suggested to help guide future community development for sensor description and registration. This article contributes to the design and implementation of affordable, self-documenting, near-real-time geospatial sensor webs for environmental monitoring using international standards.

Research on Security Architecture Based on Web Service System

Web service is a distributed Web application model, with platform independence, openness, loose coupling and other features. These features bring convenience to application integration, which also faces many security issues, mainly for computer hardware, applications, buffer overflows, message transmission process and other security threats. XML Web services architecture strengthen the security threats defense through digital signatures, encryption, and a series of measures of WS-Security by the sender, the receiver, the key server and assertion server which consist of SOAP security with characteristics like integrity, confidentiality, etc., effectively guaranteeing the safe operation of the Web services architecture.

Multi Criteria Decision Making System for Learning Object Repository

Sustainability and reusability of learning objects are important. In addition, reusability and effective use of learning object are provided by metadata. There are massive multimedia materials in learning object repository (LOR). Therefore, selection difficulty of appropriate learning object (LO) issue is emerged. In this context, effective and reliable method has to be found to select reliable and suitable LO. In addition, searching and using a learning object in learning object repository (LOR) may take too much time. Generally, this searching process is done through metadata from LOR. If the selection criteria do not exactly match metadata values, it may not possible to obtain the appropriate LO. Analytic Hierarchy Process (AHP) which is a multi- criteria decision making (MCDM) method for addressing complicated problems reduces the waste of time and improves the accuracy of decision making. For these reason, AHP can meet the requirements of LO selection. In this study, the SDUNESA LOR software has been developed for selection of suitable LO by using AHP. This web-based software stores, shares and also selects most appropriate LO in the SDUNESA LOR. AJAX, XML and SOA Web Services are used in this software which is especially developed for computer engineering education. Criteria of AHP are defined according to the computer education priorities. Obtained results show that AHP supported SDUNESA LOR software selects the most reliable and appropriate LO that meets defined criteria.

Web‐based learning object selection software using analytical hierarchy process

The concepts of sustainability and reusability have great importance in engineering education. In this context, metadata provides reusability and the effective use of Learning Objects (LOs). In addition, searching the huge LO Repository with metadata requires too much time. If the selection criteria do not exactly match the metadata values, it is not possible to find the most appropriate LO. When this situation arises, the multi-criteria decision making (MCDM) method can meet the requirements. In this study, the SDUNESA software was developed and this software allows for the selection of a suitable LO from the repository by using an analytical hierarchy process MCDM method. This web-based SDUNESA software is also used to store, share and select a suitable LO in the repository. To meet these features, the SDUNESA software contains Web 2.0 technologies such as AJAX, XML and SOA Web Services. The SDUNESA software was especially developed for computer engineering education. Instructors can use this software to select LOs with defined criteria. The parameters of the web-based SDUNESA learning object selection software that use the AHP method are defined under the computer education priorities. The obtained results show that the AHP method selects the most reliable learning object that meets the criteria.

Healthcare Web Services by E-Governance

As India is one of the fastest developing countries in the world, it is important to improve the quality of our health maintenance management and preventive medical care to extend healthy life expectancy. Today's scenario for health care in Indian e governance is in the limit of contacting 75 hospitals of the ISRO Telemedicine network only. Whilst this is currently working best of it, the limitation of this can be retarded by introducing the health care web services to each individual of the country. We believe advanced implementation of Information and Communications Technologies (ICT) may improve the medical services and health maintenance management. As medical science is fast developing and information resource is pouring in, there is urgent need for dissemination knowledge by interlinking primary, secondary and tertiary level health centers by ICT applications. This will help health personal to deliver high quality services. Moreover, IT systems have been built to support different work flows in the health sector, but the systems are rarely connected and have become islands of data. From 2006 onwards corporate IT giants are experimenting for ICT application in health sector both in Government and private hospitals. In this paper, we discuss the potentialities and expansibility of the XML Web Services based on the Adaptive Collaboration (AC) which can be aggregated by the Indian e governance system as a health care web services. We would like to present ways of improving health maintenance service and regional medical services. In order to realize better health maintenance and prevention of disease, we would like to prove that incorporating medicine, life, and work through the XML Web Services is highly effective. The developed system is using data agent concept in transferring the format of information from different medical database systems to be an international standard format of metadata known as HL7 v3.0 using XML based cloud services called the Medical Cloud system which can take advantage of the Indian cloud revolution.

Security enhancements for UDDI

AbstractThe universal description, discovery, and integration (UDDI) OASIS standard, was designed for storing, publishing, and advertising information about XML web services. Commonly used in service oriented architecture (SOA) infrastructures, the security of UDDI is often overlooked. Embedded within the specification are “optional” security measures that are commonly not implemented or enforced. In this paper we describe the UDDI security model, potential security related concerns, and mitigation strategies. Preliminary performance evaluation results are presented to show the merits of our proposed scheme. Finally, an example of the registry with additional security constraints is analyzed and evaluated for performance. Copyright © 2011 John Wiley & Sons, Ltd.

Metrics suite for maintainability of eXtensible Markup Language web services

The eXtensible Markup Language (XML) web services are emerging as the de-facto mechanism for exchanging structured information between applications. The large popularity and acceptance of web services led the developers to adopt the best practices of web service implementation and to find the ways for managing and maintaining web services more effectively. Maintainability, one of the important factors, which affects the quality of XML web services, can be controlled by the proper software metrics that are specifically designed and developed for it. In this paper, we present a suite of metrics to evaluate the quality of the XML web service in terms of its maintainability. The present suite of metrics includes: data weight of a web service description language, distinct message ratio metric, message entropy metric and message repetition scale metric. All the proposed metrics have been evaluated theoretically and validated empirically. A comparative study with similar measures proves the worth of the metric suite.

XML Secure Documents for a Secure E-Commerce Architecture

Security is one of the main issues that must be taken into consideration before implementing e-Commerce architecture. The architecture can be developed by using some security factors namely confidentiality, integrity, authentication, and non-repudiation for XML web services. This paper has examined these factors for implementing the secured system by using suitable security services like XML Encryption, XML Decryption, XML Signatures, and XML Validations. Various algorithms, implementations, and coding have been developed for security services and web services for creating the secured system. The most important part of the system is the gateway or web service which is implemented with suitable technologies for passing only the XML file throughout the whole system. This study shows how only XML files pass from client side to the server side through a central gateway with the help of web service applications. The result indicates that the XML file is delivered securely to its destination in the secured e-Commerce architecture which is mandatory for organizations like banking, insurance etc.

Integration of open access literature into the RCSB Protein Data Bank using BioLit.

BackgroundBiological data have traditionally been stored and made publicly available through a variety of on-line databases, whereas biological knowledge has traditionally been found in the printed literature. With journals now on-line and providing an increasing amount of open access content, often free of copyright restriction, this distinction between database and literature is blurring. To exploit this opportunity we present the integration of open access literature with the RCSB Protein Data Bank (PDB).ResultsBioLit provides an enhanced view of articles with markup of semantic data and links to biological databases, based on the content of the article. For example, words matching to existing biological ontologies are highlighted and database identifiers are linked to their database of origin. Among other functions, it identifies PDB IDs that are mentioned in the open access literature, by parsing the full text for all research articles in PubMed Central (PMC) and exposing the results as simple XML Web Services. Here, we integrate BioLit results with the RCSB PDB website by using these services to find PDB IDs that are mentioned in research articles and subsequently retrieving abstract, figures, and text excerpts for those articles. A new RCSB PDB literature view permits browsing through the figures and abstracts of the articles that mention a given structure. The BioLit Web Services that are providing the underlying data are publicly accessible. A client library is provided that supports querying these services (Java).ConclusionsThe integration between literature and websites, as demonstrated here with the RCSB PDB, provides a broader view for how a given structure has been analyzed and used. This approach detects the mention of a PDB structure even if it is not formally cited in the paper. Other structures related through the same literature references can also be identified, possibly providing new scientific insight. To our knowledge this is the first time that database and literature have been integrated in this way and it speaks to the opportunities afforded by open and free access to both database and literature content.

Design of SOA-based Grid Computing with Enterprise Service Bus

Due to great advantages that Service-Oriented Architecture (SOA) offers to its adopters in almost all fields, many studies tried to leverage it in grid computing. These studies focused on enabling easy access and flexible management to underlying grid resources. However, none of them allowed access to grid resources through various technologies. Rather, most of them utilized SOA in terms of XML web services without considering its limitations. In this paper, we will introduce a high level architecture that goes beyond traditional efforts in leveraging SOA in grid computing. This architecture uses Enterprise Service Bus (ESB) model by leveraging Windows Communication Foundation (WCF) to offer a number of endpoints for published services. With these endpoints different requirements from both grid clients and executors could be easily and efficiently met. Proposed architecture does not tend to supersede other SOA-based grid computing frameworks and standards. Instead, it offers a new method for wrapping grid computing resources with a set of configurable WCF services that could be utilized by these frameworks.
