[Taxacom] Data quality of aggregated datasets

I attended a meeting last week in Arizona that focused on the concept of
recognition and attribution for a broad set of activities within
informatics that constitute "work."
As Bob points out, "we" can develop all the enabling technology we can
imagine but at the end of the day, someone must actually do the review and
annotation in order improve the utility of data. The question is whether
and how they might be incentivized, recognized and rewarded for this
activity. Strategies that rely on altruism have a limited shelf life and,
as more and more aspects of the data life cycle take place online, there
are more opportunities for different actors to assert a right to be
recognized in the process.
One answer to who should be recognized for their efforts is simple and
pragmatic; anyone who asks for it, without whom, the data stops moving.
Bob is right that without the "'interest' bit", the best pipes in the
world will sit empty with nothing moving through them. On the other hand,
recognition and attribution, in the form of a citation or thanks splashed
across a web page in response to some recommendation of a data-enabling
middleman doesn't cut it either. What we need are numbers and if they
aren't dollars they need to be solid metrics that individuals can present
to demonstrate their true role.
My view is that citation and attribution need to be built into the same
infrastructure that moves and enables the data. As the data moves from
one place to another, it accrues provenance. As it is annotated,
additional actors and their roles are added to the audit trail. All of
this is tied to a resolvable identifier, like a DOI, that can be instantly
resolved to unravel this network of provenance. And in the same way that
you can get metrics regarding how often your publication is cited, you
should be able to get similar metrics for how often the data you enabled
Since data moves from place to place, a system for keeping track of all
who touch the data needs to be consistent and in place. At a meeting at
NESCent in March I learned about technologies like nanopublications
(http://nanopub.org) and ORCIDs (http://orcid.org) which seem to be
pointing in the right direction. A successful infrastructure, in other
words, incorporates "you," the experts, into "we," the network, in such a
way that the infrastructure itself starts to fade from view. Growing up
in the US in the 70s there was a shampoo ad for Vidal Sassoon, who said,
in his stylish accent, "if you don't look good, we don't look good."
That's how successful cyber-infrastructure works. It provides a venue for
brokering connections and the real metric for its success is when "we"
stop singing our own praises because "you," the users and the enablers of
the infrastructure, do it for us.
