Hi Luiz,
"RE: The expectation is that the system you are using to manage your statistics
data would filter the results by the titles and databases you subscribe"
Those of us who analyse the data (post collection) for many e-resources within
single libraries struggle with this.
It is often difficult to match title lists from publishers and third party
providers (aggregators) before merging into one data set. The biggest problem
is getting a definitive list of titles to which you have access rights, and
then making sure that the correct ISSN is included. I use ISSN (not perfect),
and filter out all zeros. Cross tab against definitive list where available
("if and only if zero=subscribed then filter =0"). Easier to do in a database
but for excel vlookup is good.
One major issue for me is that data providers insist on marking unsubscribed
titles as zero. Now zero is an important number and should not be confused with
"no data". Zero does not equate to non-subscribed - rather just non-use, so an
alpha numeric to indicate non-subscribed titles might be good, but unlikely?
Can't really see how you could manage this at the SUSHI end; more of a data
warehouse problem?
Cliff.

We are very frustrated with this. This task of classification in a single
library may be feasible, but in our consortium with dozens of thousands
e-resources, it is a painful task, if not impossible. Do e-resources names and
identifiers that come in COUNTER reports (often identifiers missing or slightly
different names) match with our KBs (SFX, Verde) will be an Herculean task.

COUNTER does not require the content provider to limit statistics for a
consortium member to just those titles the subscribed to through the
consortium. Many (if not most) content providers would have no ability to
provide this level of filtering on their content host or through the service
that manages their usage - basically the consortium purchases are simply added
to the content available to consortium member on their account with the content
provider.
The expectation is that the system you are using to manage your statistics data
would filter the results by the titles and databases you subscribe to on behalf
of your members. I know this is probably not the answer you want to hear, but
it is the reality of the situation.

Subject: [sushidevelopers] Problems when consolidating collected data
Hello everyone,
We from CAPES Consortium are having many problems when consolidating data
collected from our publishers. The major cause of these problems is that when
we ask for a report from one publisher it sends us report containing data from
titles that we don't subscribe. An example occurs when some of our members has
contract with publisher out of consortium scope. As an analogy, it's like if I
request a bank statement and it lists to me transactions of others who live in
my house. Because of that, we are having tremendous difficulty to calculate our
usage indicators.
Since numbers are distorted, we don't have an accurate usage measure, even
having a lot of statistics collected.
Shouldn't mechanisms for delivery of statistics be oriented just by the
contracts (either via web site or SUSHI), instead of be oriented by a
collection of IP addresses or a particular collection arrangement at the
publisher side?
Thanks,
Luiz Augusto
