Nowadays, we live in an interconnected ecosystem of heterogeneous services which are available anytime and anywhere. Although these services can be used individually, their combined usage provides end-users with real added value. Nevertheless, existing mashup solutions are not fully targeted to end-users. Indeed, these solutions require technical knowledge to deal with the technological heterogeneity in which they are offered. The key limitation of current mashup solutions is their general-purpose nature, which privileges expressive power over intuitiveness. As the reason for mashups was the desire of end-users to build applications responding to their situational needs, we propose a domain-specific mashup approach that "speaks the language of the user." The article presents (1) a domain-specific visual language that allows end-users to easily build mashup-based compositions, (2) a mashup schema which is a gateway between service implementations and end-users, providing a high-level description in order to hide technological issues when including services in composition; and (3) a configuration module that executes the travel mashup query and generates a personalized trip planning. The results of a user study confirm that domain-specific mashup tools lower the entry barrier to mashup development.

“…She/he either buys individual tickets or chooses one of the very few predefined packages at the available web sites and which may not entirely reach her preferences. As a matter of fact, offering a customized or personalized service is a concept which is more and more used in the domain of tourism, especially in trip planning [10]. Here, we model a scenario of a tourist who wants to visit the châteaux "along the river of the Cher" and thus designs and buys her personlized package.…”

Smart Contracts (SC for short) are gaining momentum as a suitable technology for ensuring trusted execution of Business Processes (BP for short) in open environment. Nevertheless, the transactional semantics of SC which follow ACID transactions are not appropriate for BP characteristics. Indeed, it is admitted that ACID transactions are limited to cope with complex control structure and long running execution of BP. Transactional Business Processes (TBP for short) have emerged as an extension to ACID models to overcome these limits. A TBP ensures transactional reliability of advanced transactions having a control structure as complex as for BP. In this paper, we propose an approach that builds on SC and extends them to implement TBP. We extend Caterpillar, an existing BP execution engine developed on top of Ethereum, to implement our approach and support the execution of TBP.

“…The existing solutions compete to offer the most "personalized" itinerary like CART. CART models the trip planning problem as configuration of composite services [3]. Authors adopt an interactive and incremental data mashup process applied on data extracted from multiple web services to deliver a set of itineraries that respond the best to the user's preferences.…”

“…Some elements are subject to certain conditions like the fees which depend on the age of the user, existence of an handicap situation or the season in which the tourist visits the PoI. To illustrate our case study let's consider the following scenario inspired from [3]: Alice, who lives in Tours, will welcome soon her English friend Gina and she would like to organize a Loire Valley tour to get her friend acquainted with her region and its historic monuments. Alice uses the itinerary recommending system CART 1 to design her personalized tour (see Fig.…”

“…Due to customization aspect and increasing interaction with connected devices, the composition of touristic itineraries process is difficult to structure as user requirements change and so does the data services selected to construct them. CART (Configured mAshup Recommender application for personalized Trip planning) [1], [3], as an itinerary planning system, overcomes this problem by using a data mashup based approach [1] to aggregate data collected from different web resources in order to offer a set of personalized trip plans. Logically, the deployment and execution of touristic itineraries, which represent one of the main contributions in this work, will not be based on an orchestration where a single entity has full control and knowledge about all involved participants and tasks.…”

Blockchain's Fame Reaches the Execution of Personalized Touristic Itineraries

Blockchain trends cover more and more tech domains making it one of the most used technologies in the last few years. This is due to two essential aspects. First, it is a distributed peer-to-peer network where there is no need for third part to execute operations between peers. Second, blockchain implements mechanisms to make the most data sensitive operations executed in a trusted way. Regarding these attractive aspects, we intend in this work to use the blockchain technology for the implementation of touristic itineraries. We consider the latter as process choreographies involving different participants. We intend to model and execute the touristic itineraries generated from a personalized trip planner called CART in raw XML format in a way that respects this collaborative aspect and resolves the problem of trust. We will propose a pattern and its transformation rules to reconstruct the itineraries presented in declarative annotations such as XML to smart contracts written in some smart contract-specific programming language called Solidity. Experimental results show promising perspectives of the deployment of the proposed solution to execute touristic plans.
