What makes open data not quality-ready?
Cowardice to open interesting data
Trying to opening “perfect” open data leads to not open data at all
-Access to API is in some cases (VBB Brandenburg) very difficult)
-Standardization can be too confusing ('confusion of standards")
-Big XML are sometimes a barrier to data quality
-When documentation is missing it is not good quality
- Data production bias - we need to be aware of coverage and make sure it is looking like the entire population. You need to be aware of the sample - importance of the methodology of the sample as well.
-Timely of the data and the updates.
- There is a lot of data productions that is in a non-machine processable format - need to structure the unstrcuture
- no capacity to high quality data, speacialized capacity in the topic that you cover.
Examples for bad data -
Ecuador public data education - Change of IT systems creates friction in the data, no quality control and it is not open to the public.
German Member of Parliament Income Data (published on website)
-only categories (10 categories ending with 100.000+)
-no given format (not machine processing possible)
EcoCounter API (enumerates bikers and )
-Error margin is about 20%
-4 different PHP files with different parameters -> very confusing
-outcomes: GO-Json in bad structure
-no access allowed
Knesset Open Data
-No unique identifier of law bill (changing to different comitees)
-No documentation about the API
-Tech-team does not understand the basic concepts
-Block scraping from website
What problem do we need to tackle first?
Documentation - We need not to create a perfect documentation, but release it fast and often over time, it is always evolving, How can we create better documentation processes? How do you deal with noise?
Standards - How can we become more aware to standards and to make data more structure?
How can we praise good examples so we can learn from (without over glorify them)
How can we give feedback about bad data and not only complain but to give feedback.
How can be more consistent?
