John, (01)
As per usual, I agree with your core insights and key message. That
said, I would like to add that "Big Data" and "Data Scientists" are
buzzwords *primarily* conjured up by marketeers who lack profound
understanding of the fundamental challenges that have dogged data since
the inception of modern computing. For instance, they are ultimately
peddling data silos because they just can't comprehend the deeper
virtues associated with open data access, integration and dissemination
(in the right form, to the right people or machines, at the optimal time). (02)
BTW -- building on you Slideshare reference: (03)
1.
http://www.slideshare.net/Dataversity/dataed-online-a-practical-approach-to-data-modeling-12007838/50 (04)
-- that's a hyperlink that denotes the specific slide you mentioned
(Data Scientists still don't appreciate the value of Hyperlinks as
denotation mechanisms and super keys (05)
2.
http://linkeddata.uriburner.com/about/id/entity/http/www.slideshare.net/Dataversity/dataed-online-a-practical-approach-to-data-modeling-12007838 (06)
-- link (in the form of a Linked Data URI style of super key ) that
denotes the actual slideshare hosted presentation (07)
3. http://bit.ly/TuVFkW -- entity description page that lends itself to
follow-your-nose exploration through a Linked Data based Entity
Relationship Graph (08)
4. http://bit.ly/RlTth3 -- presentations grouped by topic . (09)
Personally, I think we might as well add the moniker "Data Artist" to
the mix. This would define those that are interested in remixing
heterogeneous data sources, and like artists do, share those remixes by
leveraging existing standards such as those that drive the Internet and
World Wide Web :-) (010)
