DEFINITION: Human Interface ABB is an Application Interface enabling the exchange of data between an individual and a service. This ABB is a key interoperability enabler (*) for assessing compatible interfaces. Source: ISA2 - EIA Action (https://ec.europa.eu/isa2/eif_en.) (*)DECISION (EU) 2015/2240 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 25 November 2015 establishing a programme on interoperability solutions and common frameworks for European public administrations, businesses and citizens (ISA2 programme) as a means for modernising the public sector. Syn. User interface, UI, Graphical User Interface, GUI INTEROPERABILITY SALIENCY: IoP Dimension: Behavioral IoP The Human Interface ABB is a key interoperability enabler because it supports to achieve technical behavioral interoperability by enabling the exchange of data, information, and knowledge between digital public services and individuals. EXAMPLES: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): GrapesJS GrapesJS is an open-source, multi-purpose, Web Builder Framework which combines different tools and features with the goal to help you (or users of your application) to build HTML templates without any knowledge of coding. It's a perfect solution to replace the common WYSIWYG editors, which are good for content editing but inappropriate for creating HTML structures. You can see it in action with the official demos, but using its API you're able to build your own editors. Source: (https://grapesjs.com/)
