unstructured format:
So far, almost data from radiation monitoring
sites are provided as text or list style which is
NOT machine readable (even some sites provides
scanned PDF of a printed paper, Oh!).

The lack of temporal metadata
Temporal metadata help providing information about the
development of the radiation data before and after the
explosion of the three reactors. The absence of metadata
among the information published online obstructed the
creation of dynamic visualizations which could have given an
idea of the chronology of the situation. In one of his blog
posts, the computer programmer Marian Steinbach
emphasized the fact that temporal metadata are
indispensable for comparing data on radiation before and
after the accident:
The bad thing about the MEXT not publishing
historic values in a proper way is that we cannot
see if that sensor was always above the others.
That's why time series data is so important
