Radio Frequency Identification (RFID) techniques are considered relevant building blocks for the Internet of Things. The interoperability across different RFID software and hardware infrastructures is a key requirement for achieving effective and wide-scale Internet of Thing deployments. In this context, the EPC Information Service (EPCIS) is a set of standard specifications for sharing RFID-related data (i.e., EPC events) both within and across enterprises. Although the EPCIS specifies a set of HTTP and Web Service interfaces for querying and adding EPC events, interoperability and easiness of use is hindered by the fact that client applications should be aware of the repositories that are authoritative for one or more given queries and links among related events are not explicitly represented in response messages. In this paper we argue that, by leveraging emerging REST and Linked Data paradigms, EPC events can be handled as a graph of globally-addressable information resources that can be navigated, queried, and aggregated through a uniform interface and seamlessly across organization domains. To validate this approach, we have developed a prototype that exposes the EPCIS interfaces as a set of REST APIs. The prototype implementation exploits the information modeling and management capabilities provided by a framework, called InterDataNet (IDN), that we conceived and developed to ease the realization of the Web of Data and Linked Data applications.

“…Unlike static composition, in dynamic composition, service components are selected at runtime; and a composition plan based on functional and non-functional requirements is generated and executed also at runtime. Dynamic composition strategies are categorised in several ways (D'Mello et al, 2011): based on constraints and business rules (Orriëns et al, 2003), based on planning techniques from artificial intelligence (Zhang et al, 2010), based on interaction and user customisation (Agarwal and Jalote, 2010), based on contextual information (Medjahed and Atif, 2007) and based on service's signature (input and output parameters) (Paganelli and Parlanti, 2013). From a different perspective (Alamri et al, 2006), dynamic composition strategies can be grouped into those that use wrappers or adapters to create a new service interface at runtime; others use a language describing the composition; others are based on workflows and an abstract process model where each activity can be linked to a service.…”

Service composition is one of the principles of service-oriented architecture; it enables reuse and allows developers to combine existing services in order to create new services that in turn can be part of another composition. Dynamic composition requires that service components are chosen from a set of services with equal or similar functionality at runtime and possibly automatically. The adoption of the REST services in the industry has led to a growing number of services of this type, many with similar functionality. The existing dynamic composition techniques are method-oriented whereas REST is resource-oriented and consider only traditional (WSDL/SOAP) services. We propose SAW-Q, an extension of simple additive weighting (SAW), as a novel dynamic composition technique that follows the principles of the REST style. Additionally, SAW-Q models quality attributes as a function of the actual service demand instead of the traditional constant values. Our model is much more accurate when compared to real implementation, positively improving the quality of dynamic service compositions.

“… name the resource using a URI;  identify the subset of allowed operations on that resource;  design the representation(s) of the resource as accepted by the client (in a request) and sent to the client in a response;  connect the resource with other resources through hyperlinks;  analyze the typical course of events by considering how the service is supposed to behave and possible error conditions. In some cases, an operation on a resource (i.e., a RESTful service) can be executed by invoking a set of operations on the resource or on different resources [35]. These types of operations are typically referred to as "composite RESTful services".…”

Drug prescription and administration processes strongly impact on the occurrence of risks in medical settings for they can be sources of adverse drug events (ADEs). A properly engineered use of information and communication technologies has proven to be a promising approach to reduce these risks. In this study, we propose PHARMA, a web information system which supports healthcare staff in the secure cooperative execution of drug prescription, transcription and registration tasks. PHARMA allows the easy sharing and management of documents containing drug-related information (i.e., drug prescriptions, medical reports, screening), which is often inconsistent and scattered across different information systems and heterogeneous organization domains (e.g., departments, other hospital facilities). PHARMA enables users to access such information in a consistent and secure way, through the adoption of REST and web-oriented design paradigms and protocols. We describe the implementation of the PHARMA prototype, and we discuss the results of the usability evaluation that we carried out with the staff of a hospital in Florence, Italy.
