Ocean Networks Canada (ONC) is a not-for-profit society that operates and manages innovative cabled observatories which supply continuous power and Internet connectivity to scientific instruments located in coastal, deep-ocean, and Arctic environments. The data from the instruments are archived, quality-controlled, and made freely available to researchers, educators, and the public. The Oceans 2.0...
This paper presents monitoring as a service for networked medical cyber-physical systems in the operating room based on the recent IEEE 11073 standards for interoperable medical device communication. Runtime Verification techniques are used to allow for a formal specification and verification. Based on the specification so called monitors are automatically synthesized. At runtime, the monitors observe...
This paper describes an RDF data model for repositories concerned with managing various aspects of the life cycle of research outputs, such as articles, data sets or learning objects. Using the figshare application as a use-case and starting from its relational model, it proposes a new mechanism for storing, enhancing and disseminating metadata, using workflows specific to the linked data ecosystem,...
The Internet of Things (IoT) considers interconnected things e.g., devices that consumes web services through the internet. Such kind of devices may vary from smart phones, smart TVs, medical devices or industrial devices. Thanks to the development of the ICT field, many standards supports the existence of the IoT devices: HTTP (Hypertext Transferring Protocol), MQTT (Message Queue Telemetry Transport),...
Paper presents a solution providing OPC UA connectivity from a common web user using web technologies. Integration of OPC UA with the web may represent an important contribution to enhance its interoperability, allowing integration with web applications, IoT and WoT. The main difference with the solutions available in literature is that user may have no knowledge of OPC UA standard. A web-based platform...
With the advancement of Web service technologies, more and more spatial data and analysis functions are available on the web. Scientific workflows are widely used to orchestrate services to solve complex geospatial problems. The ontology for processing service orchestration (OPSO) is developed to empower domain experts to explore large datasets and complex processing workflows iteratively and collaboratively...
Agricultural drought greatly impacts the crop yield. Monitoring agricultural drought can deliver critical information to farmers on when, where and how much to irrigate. However, precisely monitoring which requires many kinds of data sources and data fusion and mining is still a huge challenge for scientists. In recent years, many data sources like remote sensed hyperspectral images are released online...
Model-Oriented Web Services (MOWS) are a specific kind of Web Services (WS) that employ models for artifacts, including data transmission. They foster reuse due to its higher abstraction levels, and allow to visualize the data as models that represent a common language. However, it is important to study possible disadvantages when compared to traditional WS systems. Therefore, in this paper, we present...
This work presents a preliminary proposal of a simple architecture for the development of heterogeneous applications, in order to allow the interoperability of applications in digital TV, mobile and web, for its incorporation in IoT. An MDA-based architecture is presented to develop applications based on a high-level abstraction, for which a brief review of MDA concepts and the state of the art is...
The API Economy trend is nowadays a concrete opportunity to go beyond the traditional development of vertical ICT solutions and to unlock additional business value by enabling innovative collaboration patterns between different players, e.g., companies, public authorities and researchers. Thus, an effective API Economy initiative has to be comprehensive, focusing not only on technical issues but also...
In service oriented architecture, workflow discovery and web service composition (WSC) are two major challenges and many works have been carried out in the recent years. In this work, we address the problem of WSC in a multi-cloud environment. All existing methods assume that a feasible solution exists and solves the WSC problem, however when user constraints are hard, a feasible solution might not...
The paper presents a web-based platform able to offer access to one or more OPC UA Servers. The proposed platform may be used by web-users to exchange data with OPC UA Server without any knowledge of the standard. The software solution described in the paper is available on GitHub.
There are already plenty of Internet of Things (IoT) architectures and systems available worldwide and this creates challenges for software development and systems entities that use these platforms. Global visibility and interoperability through the exposure of these platforms via the web can be achieved through a new paradigm to support an open framework for Web of Things (WoT), which is analogous...
This paper proposes a system integrating device manager, IoT Solution, and Business Process Model and Notation (BPMN) tools. With these tools, domain expert can draw the process with specifying how to connect devices all together. Moreover, domain expert can specify what kind of device is needed instead of explicitly specifying which device is needed, which addresses the IoT feature, mobility. This...
Web Services can be used as a communication structure for embedded devices. Out of numerous Web Service specifications there is a subset (Profile) to implement Web Services on resource constrained devices, called Devices Profile for Web Services (DPWS). The resulting service oriented architecture enables the user to discover new devices, e.g., in the local smart home network. The open standards for...
Exploiting and exploring the data issued from heterogeneous sources present a challenge for scientists and decision makers alike. Despite the huge explosion and the availability of geospatial data, the entities that produce them have faced increasing difficulties at the level of harmonization of this information, and especially when it is dealing with structural heterogeneity (schematic). Indeed,...
REST service are generally more appropriate for smartphones than its counterpart, SOAP. However, the flexibility, scalability and performance gained through REST services are never enough to meet the goal of addressing the complex and mobile relationships among people. That is, usability of the REST service must be enhanced for involving none-programmers to compose services on their smartphones thereby...
We are in Big Data technology, through which we analysis of the large volume of data like, peta data. Where there are many challenges in bigdata processing like, scalability issues, heterogeneity, error-handling, privacy, timeliness, source, and visualization, at all stages of the data analysis pipeline from data acquisition to final out come of data. To over come above significant problem, the technical...
Native Web communication protocols are the pivotal components of Web services, applications and systems. In particular, HTTP is a de facto protocol standard used in almost all Web services and systems. Consequently, it is one of the crucial protocols responsible for the performance of Web services and systems. HTTP/1.1 has been successfully deployed in Web services and systems for the last two decades...
It needs to be studied how to integrate the new standards of medical waveform format resent version published by ISO22077-2015 (MWF) and current executed standards for a suitable and detail application of MWF. Methods: 1. Header Information of ISO22077 about demographics was further encoded with the standard from “serials standard of WS for health information” (WSx), such as WS 363/364-2012 issued...
