[ckan-discuss] Topic list (vocabulary/valuelist) for classifying datasets .

Wed Jun 20 09:40:00 BST 2012

Hi all,

@Pablo: Looking at the IPTC Media Topics, I see some topics that seem
quite suitable (Environment, Politics, etc), but also some that are not
a logical choice for the government open data domain (Human interest,
Lifestyle and leisure, Animation, Fashion, etc.). Furthermore, I do not
think that this topic list is used extensively within governments, as
the intended domain for the list is journalism, which is not a
responsibility of the government (at least not in most countries ;-) ).
This does not help the reuse of dataset records tagged with such topics,
as a translation to a gov domain topic list will be necessary if you
want to reuse it. So for me it is not so much a matter of trusting
Eurovoc or IPTC more, but it is more a matter of the best fit &
reusability for the open data domain. 

Looking at the discussion so far, I believe Eurovoc still seems to be
the best candidate. I have already done a short analysis of the fit
between Eurovoc and the current datasets in our database and it seems OK
(again, not exactly perfect, but that's not what I am expecting). I'll
look into it using a larger sample and let you know. This may take me a
while to complete as we are currently redesiging our data portal. In the
meantime, I'd be very interested to hear from others who have tackled
this problem. 

Best regards,
