This work explores how sustainable citizen collaboration to foster Open Government can be achieved by means of Blockchain-based solution. The technical feasibility and economic viability of a set of extensions of CKAN tool, bringing together Internet of People (IoP) related technologies such as Blockchain and crowdsourcing, to address sustainability in Open Government Portals is analysed. For that, a use case validation is performed, and the costs of its deployment assessed. The aim is to show how IoP promoting technologies enhance Public Administration (PA) and citizen collaboration to meet common interest objectives.

The increase in the number of large scale events held indoors (i.e. conferences, business events) opens new opportunities for crowd monitoring, access controlling as a way to prevent risks, provide further information about the event's development. In addition, the availability of already connectable devices among attendees allows to perform non-intrusive positioning during the event, without the need of specific tracking devices. We present a platform that integrates the access control management, attendees monitoring based on passive Wi-Fi requests detection,, the analysis, visualization of the captured information using an scalable software architecture. The analysis of the captured information enables to detect crowded zones, the attendance status during the event's performance, after its ending. In addition, the proposed platform has been evaluated using information captured in a real event.

Educational remote laboratories are a software and hardware tool that allows students to remotely access real equipment located in universities as if they were in a hands-on-lab session. Their integration in Content and Learning Management Systems (CMSs or LMSs) has been an active research topic for years, supporting mainly ad hoc solutions. A notable exception has been the use of federation protocols -commonly used for sharing laboratories from one university to other-, for actually sharing laboratories from a remote laboratory system to a C/LMS. This approach opened new doors in the simplification of the process, since it did not require the remote laboratories to make any type of change. The focus of this contribution is to provide a solution to decrease the number of functionalities required for creating an integration by providing a software component that reuses them. As shown in the contribution, this component has been implemented and two remote laboratory management systems (which provide access to multiple remote laboratories) are already supported, and a third one is under development. In the C/LMS side, all the LMSs supporting IMS LTI are supported, and HTTP APIs are provided for being supported by other systems. Indeed, the contribution describes its support in the Joomla CMS and in the Moodle 1.9 and dotLRN LMSs which do not support IMS LTI. The solution, called gateway4labs, is an open source initiative which targets to be used in production.

An educational remote laboratory is a software and hardware tool that allows students to remotely access real equipment located in the university as if they were in a hands-on-lab session. Federations of remote laboratories have existed for years: they are based on enabling two universities to exchange remote laboratories directly, without registering students of the latter on the former university. Integration of remote laboratories on Learning Management Systems (LMS) or Content Management Systems (CMS) have also been addressed in the past, enabling institutions to delegate the authentication or authorization of the experiments to the LMS/CMS. However, these integrations are usually achieved in an ad hoc way, integrating each particular laboratory to a LMS/CMS. This contribution studies the use of federation models to integrate remote laboratory management systems in LMS/CMSs, since both approaches (integrating a laboratory on an a external electronic learning tool, and integrating a laboratory on other laboratory) are essentially equivalent. The contribution defines two case studies to evaluate this approach, showing how this integration is achieved on a LMS (Moodle) and on a CMS (Joomla).
