2. Open data is data that is made available by organisations, businesses and
individuals for anyone to access, use and share.
Open data has to have a licence that says it is open data. Without a licence, the data can’t be reused.
The licence might also say:
●that people who use the data must credit whoever is publishing it (this is called attribution)
●that people who mix the data with other data have to also release the results as open data (this is called
share-alike)

4. Context of Scale
-Traditional tech architecture will not scale
to these volumes
-People and devices need to find data
easily
