What is Open Data?
01
Open Data is
data that anyone can access, use
and share
Access:
Data becomes accessible
when it is available online.

by being made available in a machine-readable format.

#3
Share:

It is very important that
the data is licensed.

Open data becomes usable when made available in a common, machine-readable format. Open data must be licensed.
Which allows people to use the data, transform it, combine and share, even commercially.

What is Data?
01
Data may include non-textual material such as maps, chemical compounds, mathematical and scientific formulae, medical data, locations, pictures, prices, dates.
Data is the tool to represent the reality
03
What makes Data Open?
01
In order for data to be open, it should be accessible (published online) and licensed for anyone to access, use and share.
Limitations
Open data must be free to use which doesn't mean free to access. There is often a cost to creating, maintaining and publishing usable data.  
Format, structure and machine readability make data more usable.
Anyone should be free to use, modify, combine and share the data, even commercially

IMPORTANT POINT!
Unless you have a licence,
data may be ‘publicly available’, but users will not have permission to access, use and share it.
Without a licence, users may find themselves in a legally grey area.

Hidden Data
‘Open data’ does not only mean datasets available to download. Downloadable open data represents only a small fraction of the available data on the Web. The majority of data available on the Web is hidden from the human eye. However, machines can find and read this data.
Sourse: ODI
Downloadable open data files are just one type of data on the Web. Much more data remains hidden in website code.
Hidden means Open?
The licences for this hidden data are not always clear. Just because the data is machine-readable on a public website does not make it open data. If you are uncertain about whether hidden data is openly licensed, check with the website publisher.
The fact you can extract hidden data does not make the data open.

Open Data Concerns
01
Reengineering of data to get personal information
Open data should be anonymous so no one’s privacy is threatened
