Barriers to adoption
Unfamiliarity
(Unclear) licensing
- What happens to derived products?
Informal nature of content:
- Spam, offensive content – in some settings
Spatial heterogeneity Use by officials

Barriers to adoption
Built-in biases, (perceived) qualityissues
SLAs vs. undocumented, inofficial, deprecated APIs
Comparison with / availability of official data
Complexity

What would be of interest?
In general, topics where:
no (or bad) official data exists
said data is prohibitively expensive
data has to be comparable across borders
we are interested in informality

What would be of interest?
Examples:
Movement data- Mode of transport
- Metrics
- Socio-demography
- Purpose, goal
Pooled near-realtime data- Event detection, e.g. damage assessment wrt insurance
claims
- Emergency operations

Administrations familiarise themselveswith the «open» movement
OGD is not perfect triggers feedbackand interaction between stakeholders
… and OGD?
