Open Data definition Open Data vs Public Sector Information Levels of openness of data [TBL 2010] • Online but not re-usable on open licenses • Online and open-licensed but only human-readable • Online, open-licensed and structured • Online, open-licensed and structured (non-proprietary format) • All of above and identifiable with URI • All of above and linkable to get network-effect and added-value 5 Public data can be completely useful only if it has an ability to be linked with other data sets and create new social and economical value [Sashinskaya, M. 2014]

- 8. Open Data for Smart Cities Smart people are the most important component of a Smart city • User-oriented participation • Talent • Entrepreneurship City government may not need to produce the apps, but can provide the platform being a facilitator A modern city has many data generated and collected by citizens every day • This data can create added value (social and economical) specially if is linkable and combined with other public data 7

- 11. Different Sources of Context Context information may come from many sources which may vary over time: • Existing Systems dealing with management of municipal services • Sensor networks (Internet of Things) • Third-party smart city APPs Source of information needs to be transparent to applications accessing context information NGSI Standard API Current traffic in street “X” A sensor in a pedestrian street Citizen’s car app or smartphone Notify traffic in street “X” Current traffic in street “X” Public Transport System

Editor's Notes
- Let’s start with a sentence by former Digital Agenda Commissioner, who puts the focus on data as the main driver for a digital era
- Re-usage – non-propietary formats NGSI Linkable – Data models Data can be linked and merged to generate added value data
- Link the concept of NGSI with all the data requirements already presented
- In a smart city, the applications build on top of the platform require to gather and manage context information, referring to any relevant data available in the city. In this way, context information may come from very different sources, such as real time data coming from an IoT layer, static datasets published in a data platform, information published by the city hall, dynamic data generated by third party applications, etc. It can be seen, that dealing with all these heterogeneous data sources might be difficult, slowing down the innovation in the city. To deal with this problem, FIWARE provides an standard API for the management of context information, so it is exposed using a single format, which makes transparent the source of the data.
- Not only static resources are to be stored in CKAN, but also live-data, as any other data coming through starndard APIs of NGSI from other components/apps/services

To deal with this problem, FIWARE provides an standard API for the management of context information, so it is exposed using a single format, which makes transparent the source of the data.
- Towards a real ecosystem of apps and data The situation presented untill now does foster innovation by offering the tools to create value with open data. The OD platform, the standards, the freedom to re-use the data are key factors that leverage the potential for a wide ecosystem of smart applications and services. Though there is a step forward in the path for smart cities, which means monetization. Monetization of the data, the apps, the services, so as to create a value-added chain that attracts even more attention to the development of those services. For accomplishing that, it is neccessary - The means for identity management and authentication - Management of access rights for data, apps and services - Having an inventory of existing data sources, and services (Activation and configuration API) - Bind a pricing model to data, apps and services - make available data, apps, and services to potential customers - Allow to acquire products (automatic permission management for service activation) - Allow to manage acquired products (renew, suspend, terminate, show usage, etc) - Data and service acquisition need pay-per-use - Usage data management - Accounting - Management of charges and payments (Charges and settlement notes) - Management of revenue sharing - Management of agreements and engaged parties
- Business API standardization is a key factor for the creation of a real ecosystem of apps and data. Without strong standardization efforts, full maturity level of smart cities (third parties enriching city-supplied data and enabling monetization) is complicated. Without standardization, a real apps and data ecosystem would be severely limited. In this sense, TM Forum has standardized a set of Business Ecosystem APIs that enables repeatable and flexible integration among operations and management systems, making it easier to create, build and operate complex innovative services. FIWARE, and specifically the Business API Ecosystem GE, has become the first integrated implementation of first set of available APIs, and is evolving to put the newly released ones in place. Therefore, besides being a marketplace with the obvious benefits from the monetization of apps and data, it takes advantage of the benefits on operation and management offered by such standards. Since all of the interactions with the enabler are standard, companies that plan to offer data and apps in such ecosystem do not need to ad-hoc adapt their systems.
- In the age of the digital economy, services are typically delivered through a sophisticated partnering of multiple providers who are all using different systems and interfaces. TM Forum REST based APIs are designed for use on anything from IoT device management to complex B2B value fabrics and they apply to all the topics our members are focused on: IoT, Digital Health, Smart Grid, Big Data, NFV, Next Generation OSS/BSS and more. TM Forum’s Ecosystem APIs provide end-to-end management capabilities to improve the consistency and effectiveness of communications across boundaries. One of the most important parts of the TM Forum API program is a set of standard REST based APIs that enable rapid, repeatable, and flexible integration among operations and management systems.
