Real-life datasets have NO or INCOMPATIBLE schemes
This prevents data interoperability.

Reusability of data is skewed in favour
of larger players and smaller players
have to do a lot of work to even offer
competitive services
Ecosystem
want the data
small
large players
T
have all the data
- dictate schema -
players have control over changes

Schemas and Community
12
① schemas are
open
maintained
by community
② remove points of control for data
hoarding
bottlenecks for innovation
③ reduce burden for data escpont / impost
reduce complexity of reuse
④ automate uplift / down lift /mapping

In Conclusion...
14
• DATA PORTABILITY = MORE DATA
=
MORE SERVICES
= INTEROPERABILITY
° SCHEMAS = MATCH
= ALIGN
= MAINTAIN
°
DATA PIPELINES = UPLIFT / DOWN LIFT
= CONVERSIONS
