Choosing the right technologies to build an urban-scale IoT system can be challenging. There is often a focus on low-level architectural details such as scalability of message handling. In our experience building information requires high-level holistic approach that mixes traditional data collection from vendor-specific cloud backends, together with collected directly embedded hardware and mobile devices. Supporting this heterogeneous environment prove challenging lead complex systems are...

Sustainability has been an important topic in UK schools for some time, most notably since the Sustainable School Strategy was proposed by Department Education (DFES) 2006. However, as smart city technologies emerge and show real promise contributing to a more sustainable future, it is becoming apparent that new skills working with big urban data sets drive these innovations must be taught upcoming generations ensure they can active citizens. Current practice within distribute teaching of...

In this paper we define and formalize the model transformations that complete methodological approach for development of Object-Relational (OR) Databases (DB) proposed in MIDAS, a driven methodology Web Information Systems. proposal Platform Independent Model is conceptual data while Specific represents OR DB schema. Since both them will be represented UML, also summarize an UML profile modeling. work focus on formalization mappings needed to get schema from model. We have first specified...

A bottom-up approach to smart cities places citizens in an active role of contributing, analysing and interpreting data pursuit tackling local urban challenges building a more sustainable future city. This vision can only be realised if have sufficient literacy skills experience large, complex, messy, ever expanding sets. Schools typically focus on teaching handling using small, personally collected sets obtained through scientific experimentation, leading gap between what is being taught...

The growing amount of data on the Internet has led to a situation in which it is essential process these generate new services with specific aim improving people's daily living conditions. Transport utmost importance, since everyday people have move around perform some tasks, such as going work, studying and shopping, this means that number journeys by public transport grows daily. People special needs make large trips, but they do not sufficient information about accessibility routes want...

Abstract Modelling is one of the most frequent tasks in area information systems (ISs), with models such as schemata, ontologies, patterns and architectures forming bases for their creation. Very often, however, difference between these types not clear causes confusion erratic use terms. The aim this paper to clarify concept model through a study some more common ones used ISs. This proposal presented an ontology, where we show how conceptualize according role development IS: understood...

The emerging Semantic Web and, in particular, services (SWS), demands the inclusion of new components applications involving this technology. Therefore, development methodologies must be tailored to support systematic such components. In previous works we presented a UML profile, which extends SOD-M method for service oriented Information System MIDAS model-driven framework, address Services using WSMO (Web Service Modeling Ontology). profile allows modeling elements required by Services....

Human mobility is one of the most important concerns in smart city initiatives and especially relevant when combined with accessibility issues. This paper describes work context Access@City Research Project, which seeks to improve public transport system by using available information (open data, semantic-aware knowledge) provided organisations. However, these organisations provide partial a lot still only on their websites, or simply does not exist. absence can be tackled playful approach –...

Transport is one the aspects that most critically affects population's life conditions, particularly in case of those people with various special mobility needs. In spite existence numerous Websites provide information about public transport services, there a lack open data regarding accessible transportation systems. We are, therefore, working on development technological framework for processing, management and exploitation data, goal promoting accessibility to city transport, which taking...

One of the key factors employed to define well-being citizens in urban environment is mobility, since it defines a set flows and connections that constrain those citizens' individual collective behaviour. However, complexity this activity on scale city makes complex problem computational terms. main reasons for asymmetry information: different actors have access only partial or outdated information, many relevant data are simply unavailable. In article, we propose integration architecture...
