- A distributed catalogue of datasets and apps- Aim Citizen/Stakeholder Engagement

C1: Data DiscoveryAt present: Centralized search across Observatory sites http://search.webobservatory.org/ Using metadata (schema.org) and datasets IoT datasets description Hypercat

Moving towards: Distributed search reaching lightweight computers/base stations

...

C2/C3: Data Privacy & Diverse StakeholdersAdopting reverse proxy and URL obfuscating technologies to protect private and sensitive data

Data Publisher controls location, visibility & access of datasets

C2/C3: Access Control & Diverse Stakeholders

Present IoT Observatory - distinguishes b/w metadata and content

Working towards Easy-to-use Web interface for Access Control Granularity - IoT datasets, meta-data, aggregations & correlationsEntities- Data owner(s), publisher(s), device(s)Data owners/Publishers able to evaluate trade-offs, permit & restrict data processing/usageImplement data sharing negotiations with the stakeholders

- Privacy by processing will be a bottom-up access control based on stakeholders artefacts of what they wish to share based on what processing the particular data can go through. - It is important to control the access to meta-data as it can be as relevant as the content itself
