The purpose of this paper is to describe TraceALL which is a Semantic Web (SW), ontology‐based, service‐oriented framework which aims to provide the necessary infrastructure enabling food industry (particularly SMEs) to implement traceability applications using an innovative generic framework.
The framework builds upon the idea of the Semantic Web and provides an open and extensible underlying platform that allows different traceability interconnected applications to be designed and developed. More specifically, the framework provides a formal, ontology‐based, general‐purpose methodology to support knowledge representation and information modelling in traceability systems. Additionally, it suggests an open application framework based on widely used Semantic Web standards. Finally it provides a set of core services for storing, processing and retrieving traceability information in a scalable way. These components, taken together, facilitate the efficient development of next generation traceability applications.
Based on a case study which the authors executed as a proof of concept and studying the relevant literature it was found that TraceALL facilitates the development of next generation traceability applications because, from a food safety perspective, it enables all stakeholders in the food supply chain to have an information trail that follows the product's physical trail, but at the same time is cost effective, easy to manage and applicable within a globalised, networked, interoperable economic environment.
To the best of the authors' knowledge, this is the first food traceability system based completely on solid existing standards of the Semantic Web initiative. The authors consider that the inspiring analogy between resources such as those described in the Semantic Web initiative and the core traceability concept of a Traceable Resource Unit (TRU) is an extremely useful concept for developing cost‐effective traceability applications that possess many key requirements, which are described in the paper.

This paper aims to present results from a research that analyzed consumer perceptions of service quality in restaurants in four European cities – Belgrade (Serbia), Manchester (UK), Thessaloniki (Greece) and Porto (Portugal).
A total of 802 respondents have been interviewed using a structured questionnaire. The service quality statements covered food quality, building exterior, restaurant interior and layout, seating comfort, restrooms and servicing.
Within all analyzed categories (city, gender and age), servicing of food and taste of food were the most influential factors. However, this study confirmed that there are different patterns in analyzed cities. For each factor analyzed, in at least two cities, results for the items were significantly different. Consumers from different cities showed different perceptions regarding service quality in restaurants. Gender of consumers plays a significant role in the perception of interior, restroom and servicing factors in restaurants. Age of respondents was the category with no significant difference with respect to food quality, layout, restrooms and servicing.
Given the great cultural and other differences within the four cities/countries, more research is necessary to determine if similar results would be derived from different samples across various other continental and Mediterranean European cities.
In addition to increasing the theoretical understanding of the cultural aspects of the service quality, this paper can be of managerial relevance.
