Restricted CGIDE – API standards for data-sharing – October 2022 8 Data-sharing is one of the main pillars of open banking initiatives which are emerging in financial services. Innovations include the involvement of third-party providers, which facilitate access to banking records with the user’s consent, also known as payment service providers. Data-sharing promotes transparency in a digital society and supports high levels of reciprocity and cooperation within the financial ecosystem. Account aggregators are important mechanisms for the implementation of data-sharing in an open banking scheme. In most of the models described below, an account centraliser or aggregator is a point of concentration of information flows, suitably standardised and regulated. By contrast, in a decentralised model, intermediate onboarding or authentication mechanisms are enough. There are several benefits of data-sharing such as promoting a transparent digital society, achieving reciprocity and cooperation in the financial ecosystem, combining data from diverse sources to improve the performance and value of services, enabling better decision making, delivering better products and empowering data ownership by citizens. 1.1.2 API content An application programming interface (API) is a set of functions used by a software program to provide an interface that allows other consumer programs (external parties) to connect to and interact with the software program. An API may contain: (i) communication protocols; (ii) data exchange requirements; (iii) access and consumer policies; and (iv) integrity and confidential management. 1.1.3 Data serialisation Data serialisation is the process of translating one data format to another. In this process, data are serialised, but do not change, and the source and destination still have access to the same data. Software programs that exchange data but store or represent it differently require data serialisation. This mechanism is present within a data-sharing ecosystem based on API implementations. 1.1.4 API dimensions The construction of an API for data-sharing requires a series of considerations or characteristics associated with the implementation of the API itself. These quality attributes or dimensions are important in terms of API design and construction, thereby promoting the success of the API in the context of open banking (Zachariadis (2020)). Relevant considerations or characteristics include: • Download 1.78 Mb. Do'stlaringiz bilan baham: |
