a) Integration of GEs
No Design Patterns (No Reference Models,
in Particular for Data Protection, Data Trade Use Case )
● Which / How FIWRE GEs
can interwork each other??
● AWS Reference Architectures
● AWS Cloud Design Patterns (CDP)

b) Data Conversion to NGSI Data Models
Diversity of Existing Data Formats
– Need to manually convert existing data
▌ CSV
● e.g. Fukuoka Air Quality
▌ XML
▌ PDF
▌ XLSX
▌ Plain Text
▌ RDF
▌ FIWARE Data Models (JSON)
● Type: AirQualityObserved
