But, Data Quality!

• Difficult to define
relations among datasets
• Difficult to connect and
integrate between the
heterogeneous datasets
• Naive metadata
• Difficult to indicate the
same information between
the heterogeneous
datasets
• Language barrier -
written only in Korean
• City centric data -
limited to co-operate for
the public purpose

Advantages of Linked Data
we usually say..
1. Reuse of Data
2. Reducing the management cost
3. Interoperability for the integrated datasets
... Really?

16. 2nd Korea-UK Data Workshop with ODI / Dec 15, 2015
Linked Open Data World, anyway

17. 2nd Korea-UK Data Workshop with ODI / Dec 15, 2015
Linked Data Open World, really enough?

Linked Data - How?
→ This is only about agreements
for protocols, standard formats
and their definitions,
not about accessing/querying
those ‘distributed' data.
