This Group Specification provides additions and corrections to the GS-009 NGSI-LD API specification, based on feedback received from developers in the linked-data, internet-of-things, mobile-apps and smart-applications communities, as well as from end users and stakeholders.
The purpose of this Group Specification is the (preliminary) definition of a standard API for Context Information Management (CIM-API) enabling close to real-time access to information coming from many different sources (not only IoT). The document shall define how such an API enables applications to perform updates on context, register context providers which can be queried to get updates on context, query information on current and historic context information and subscribe for receiving notifications on context changes. The criteria for choice of the API characteristics shall be based on results in WI UC and WI GAP.
This Group Specification is labelled "preliminary" because it should be published widely in order to elicit comment and critique from the user communities and their comments will be used to modify and improve the later final API specification. Accordingly a feedback process shall be described in this document.
This Group Specification shall be compatible with an example data model published at the same time (see Work Item MOD0), so that implementers of appropriate software can efficiently test and compare results and interoperability.
The purpose of this Group Report is to explain with examples the usage of NGSI-LD information model and API, as defined in GS-004 prelimAPI, and considering also some use cases from GR-002 for ICT professionals. Worked examples are provided, with code fragments made available in a public repository. No changes in the GS-004 prelimAPI specification can be introduced or proposed in this document.
Defining indicators (KPIs) for Smart Cities expressing city level in terms of People, Planet, Prosperity and Governance.,
Recommendation ITU-T Y.4200 defines the requirements for the interoperability of a smart city platform (SCP) and its reference points in order to ensure the correct functioning of city services.
The SCP offers services to a smart city. Interoperability between SCPs allows the increase in the number of services provided and their quality. It enables the provision of better services to citizens, and at the same time ensures maximum efficiency, scalability and simple integration.
By permitting interoperability with other platforms the SCP will also encourage local economic development through innovation and competition.
The EN will contain normative specifications related to the accessibility of websites and mobile applications and their compliance with the essential requirements of perceivability, operability, understandability and robustness defined in the Web and Mobile Accessibility Directive
Recommendation ITU-T Y.4905 is a holistic impact framework for the assessment of smart and sustainable cities to address the effects of digital innovation on social, economic and environmental issues. Smart sustainable city (SSC) initiatives have been proposed as potential solutions to economic, social and environmental challenges and pressures encountered by cities. Advances in information and communication technologies (ICTs) enable significant transformation potential in the way city resources, services and infrastructures are planned and managed. More specifically, ICT can play an enabling role to address the urban challenges of the twenty-first century. Smart sustainable cities harness ICTs (including various subtopics under ICT such as digital transformation, data, Internet of things (IoT), digital services, etc.) and intend to deliver city enhancements through a portfolio of action items. By their very nature, SSC initiatives impact the underlying cities. It is important to identify and asses this impact. The identification and assessment of impact will allow for better planning, the setting expectations with stakeholders, better informed budgeting, more effective public private partnerships and the promotion of alternative financing mechanisms. This will also help in communicating SSC initiatives.
The ultimate objective of this Recommendation is to enhance the sustainability of identified priority sectors in smart cities, in order to optimise economic, environmental and social benefits.Cities will decide on their digital transformation priorities. For example, cities might also want to encourage collaboration to deliver desired outcomes.This kind of engagement based on the assessment framework can incentivize industry engagement and investment.Recommendation ITU-T Y.4906 contains the following:1) Introduction of the assessment framework and its components2) Identification of indicators - Examples of categories of indicators to assist in this objective for the assessment frameworks include:- Digital infrastructure;- Digital transformation initiatives for sectors;- Collaboration efforts on digital transformation;- Economic, environmental and social benefits according to sector digital transformation.3) Sector assessment and analysis
The present document describes the motivations for the standardization of technology which enables Energy Efficient IP Video Surveillance Systems over new and legacy Coaxial Infrastructures. The technology enables the transmission of both IP data and power over a single coaxial cable, and is based as much as possible on existing standards. The standardization of this technology is needed for the deployment of sustainable Video Surveillance Systems using interoperable products from different manufacturers.
