Cities’ population growth goes in hand with the development of new technologies that are becoming the key factor of the Smart City (SC) concept. It allows the implementation of efficient management solutions, operation, and sustainable development of a city to face the challenges of urbanization and improve the services for the citizens and visitors.

The concept of the SC 5.0 was first presented in Svítek, Skobelev, and Kozhevnikov (2020), where the problems of the complexity of current cities due to rigid management processes, variety of infrastructure, and SC modules, systems, subsystems, and applications were described.

To prove the concept, several practical examples were developed to cover the topics: modeling in SCs, practical implementation of multiagent technologies, the approach of creating city ontology and the city knowledge base as the instrument of semantic interoperability, and visualization possibilities of Smart Evropská as a SC Testbed used for teaching purposes.

The new organizational structure is proposed based on knowledge graphs, and practical examples are shown. The applicability of knowledge graphs to be used in combination with data management platforms for monitoring SC key performance indicators (KPIs) and providing interoperability of services is presented.

To raise consciousness among librarians and library directors about the need to structure our descriptive data for library resources in a way that is machine-actionable in the Semantic Web, not just the library silos of MARC-based systems.

Narrative overview.

By assuring library metadata is in a well-formed structure, libraries can place access to their collections on the Web where their users are.

The new cataloging code, Resource Description and Access (RDA), is one step in the direction toward more interoperability in the Semantic Web.

New perspective on this issue is to urge librarians to work with systems people and vendors for next generation systems that build on the relationships and identifying characteristics of well-formed metadata arising from use of the RDA.

Cities evolved into quite complex urban systems. The rigid management process must reflect the complexity of the current political, social, and economic environment. With the vast city growth, citizens experience new difficulties – traffic congestion, pollution, immigration, overcrowding, and inadequate services.

In our research, we analyze problems and benefits that occur with the growing complexity and offer a new concept considering every city as a live and constantly developing complex adaptive system of many participants and actors that operate in an uncertain environment. These actors (residents, businesses, transport, energy, water supply providers, entertainment, and others) are the main elements of city life.

The new concept of “Smart City 5.0” is based on a previously developed model of Smart City 4.0 (compared with Industry 4.0) and implements the Urban Digital Ecosystem, where every element can be represented by a smart agent operating on its behalf. It is shown that smart services can interact vertically and horizontally in the proposed ecosystem, supporting competition and cooperation behavior based on specialized network protocols for balancing the conflicting interests of different city actors.

The chapter describes the design principles and the general architecture of the Urban Digital Ecosystem, including the basic agent of smart service, protocols of the agent’s negotiation, the architecture, and basic principles Smart City knowledge base.

The developed evolutionary methodology of implementation will ensure a minimum of disruptions to city services during its transformation into an urban ecosystem to harmoniously balance all spheres of life and the contradictory interests of different city actors.

The platform economy reflects the business model of some of the largest and fastest-growing firms in the economy. Platform business models emerge and thrive because of the potential profit in taking advantage of transactions cost reductions to connect people for mutual benefit, and this value creation is best understood by thinking about the epistemology of decentralized market processes. Three essential aspects of knowledge are relevant to platform business models: (1) knowledge can be private and diffuse; (2) knowledge can be contextual; and (3) knowledge may not exist outside of the economic process. After defining and analyzing the technology, economic, and institutional aspects of platforms the author defines and applies market epistemology to explore how platforms harness technological and organizational features to create value-enhancing market platforms by exploiting the epistemic benefits of technology-enabled decentralized market processes. The author concludes by using this epistemic framework to propose an electricity distribution platform business model – the retail electricity industry is undergoing a process of technological dynamism, and as a regulated infrastructure industry, evolving into a decentralized market industry is presenting challenges to which this epistemic framework can bring increased understanding.

This chapter studies Digital (or Electronic) Government in Latin American (LatAm) countries from a comparative perspective. It analyzes a group of countries with a significant degree of economic diversity and public administration heterogeneity. This chapter presents data about the development of the Information Society in Latin America, regarding the diffusion of Information and Communication Technologies (ICTs) and the Internet in the countries of the region and taking into account the digital divide phenomenon. It also analyzes Digital Government from a regional perspective, pinpointing intergovernmental institutions and international organizations devoted to design and define, and, in some cases, implement, shared perspectives and a common agenda within this region. This overview is brought forward by a comparative approximation to the development of e-Government readiness in LatAm countries, using data from the United Nations reports. Additionally, this chapter analyzes sectional e-Government dimensions, including digital public administration national agendas, electronic public service delivery websites, interoperability initiatives, social media technologies, open data and open government strategies, and the future of technology in public sector of the region. Therefore, this chapter is important to understand the role of ICTs as one of the most recent sources of innovation and reform in public administrations Latin America.

Purpose – The purpose of this chapter is to illustrate the importance of using open source technologies and common standards for interoperability when implementing eHealth systems, and to illustrate this through case studies, where possible.

Design/methodology/approach – The sources used to inform this chapter draw from the implementation and evaluation of the eHealth Program in the context of the Millennium Villages Project (MVP).

Findings – As the eHealth Team was tasked to deploy an eHealth architecture, the Millennium Villages Global-Network (MVG-Net), across all 14 of the MVP sites in sub-Saharan Africa, the team not only recognized the need for standards and uniformity but also realized that context would be an important factor. Therefore, the team decided to utilize open source solutions.

Practical implications – The MVP implementation of MVG-Net provides a model for those looking to implement informatics solutions across disciplines and countries. Furthermore, there are valuable lessons learned that the eHealth community can benefit from.

Originality/value – By sharing lessons learned and developing an accessible, open source eHealth platform, we believe that we can more efficiently and rapidly achieve the health-related and collaborative Millennium Development Goals.

In Latin America, technology has been advancing faster than society is able to adjust to it on its own. Thus, information and communication professionals should merge their efforts to research and discuss the relevant role they play in the society transformed by technology.

This paper presents and discusses the initiatives that the Brazilian government and stakeholder institutions are developing in regards to ICT and memory and heritage preservation.

The international relevance of describing the Brazilian initiative of ruling the internet in a non-restrictive way shows the trend the country has adopted.

In the current context of development of the Information Society and expansion of cultural economy and digital culture in Brazil, it is imperative to define public policies for digitizing Brazilian memory and heritage collections. Such a national policy involving the three levels of the Federation as well as private institutions committed to the custody of cultural collections, should play an essential role in guiding the efforts to digital reproduction of collections and their publication on the internet.

Brazil is the first country in the world to rule the use of internet openly, in a non-restrictive way, through the Marco Civil da Internet. Since 2007, an academic initiative named Memory Network has been working to promote the digitization and access to Brazilian collections of memory and heritage.
