Re: dwbp-ISSUE-200: Can we align the quality dimension hints in DQV with the ones in ISO 25012? [Quality & Granularity Vocabulary]

The ISO standard is really a glossary of the components of Data Quality.
It defines useful terms of reference, but it doesn't tell you how to
measure or improve data quality, or even how to calculate or derive values
for the components and terms.

In my view alignment adds value in that it means we don't have to define
those terms, but I would hope we can go beyond the linguistic definitions.

Hi Nandana,


Thanks for the very  valuable input.


At least two quality dimension classifications can be considered when
providing examples  in section 7
      Dimensions defined in ISO 25012 http
      ://iso25000.com/index.php/en/iso-25000-standards/iso-25012, you have
      mentioned;
      Dimensions collected in the "Quality Assessment for Linked Data: A
      Survey",
      http://www.semantic-web-journal.net/content/quality-assessment-linked-data-survey




I tend to think we should cite both and let the DQV adopters to select the
one which best fits their needs.


In my opinion section 7 [1], "Dimensions”, should  offer a  categorisation
of quality dimensions, which is not intended to be normative: It can't be,
we actually want that  quality framework emerging in the future can define
their quality dimensions and categories as they need. As you know,  there
is a lot of  people  which work on  quality and we don't want to close the
door to  new measures which  are likely to be defined in the future.


 At the same time, I agree on  providing  examples of  categorisation for
dimensions which can  provide  guidance for those  who don’t need to define
their own dimension / categories.





So my proposal is to align the current  DQV  classifications with the ISO,
but also citing the classification from zaveri et al as a possible
classification to be adopted.


How the group feels about this proposal?


I guess that some sort of mapping between the two classifications would be
helpful, but   I am neither  sure  that mapping can be  easy  found nor it
is in the scope of our work. Perhaps we should ask to externals ( and
Zaveri, Maurino & Co in particular )  if anyone has already defined such a
mapping.





Best regards,


Riccardo

  When looking at the quality dimension hints in DQV and ISO 25012 (SQuaRE
  - Data quality model), there is a big overlap. I did an initial
  comparison and all except for relevance and statistics fit in.

  Comparison of DQV and ISO 25012 dimensions
  https://docs.google.com/spreadsheets/d/1VMe--lhbiRGvQW1eWsYhUW2TeUBVxR3hzNskIPtSZoM/edit#gid=0



  ISO 25012 provides definitions for each dimension developed by the TC. It
  will good to refer to them whenever possible and define new ones only
  when it's necessary.

  Some terms have to be unified such as
  1. Currentness, Timeliness
  2. Compliance, Conformance
