Hi All, What a tome we have created! Tx to all for the work, effort and insight. Tx Susan for asking about our top 5 picks from the Purpose List. The documents that I think are most important: 1) One not yet on our list (but so often referenced that it really must be): the EU Data Protection Directive (1995). This is the foundational document for the Article 29 Working Party opinions and so many other materials posted on our list. It is the EU law that creates the requirement of “purpose” in the collection, processing, retention, use and additional uses of data. It is the basis for this discussion (and Council of Europe Treaty 108 as well, signed by dozens of countries). Both were the first main documents to set out the requirement and definition of "purpose." I would request that both be added to our list - with the summaries already posted on the "Privacy checklist." Tx! 2) Opinion 03/2013 on Purpose Limitation by the Article 29 Working Party (issued April 2, 2013) is directly relevant to our work and providing clear input and insight to our understanding and interpretation of “purpose” as required under the EU Data Protection Directive (above). 3) the European Commission’s webpages on “Obligations of Data Controllers” and “Definition of Data Controllers” provides clear and accessible definitions and guidance as to who the "purpose" obligations apply to -- and helping us understand the obligations of those collecting data and those setting the policy for it. 4) I am still thinking about documents 4 and 5. :-) Best and have a good weekend, Kathy
