[Sigmetrics] D/T Metrics: An indicator for open access journals and repositories

[Alejandro Uribe Tirado]

This text presents the proposal and application of an indicator that has
been called "D/T Metrics" (Downloads/Time).

This indicator interacts with other variables and data that allows journals
or repositories platforms (eg. OJS or DSPACE) to qualify and obtain new
evidence at altmetrics level, in an extensive sense, beyond the direct
result of the number of downloads, which is the most commonly used
indicator in open access, considering both the golden route and the green
route.


As noted in other times, data downloads are not enough, and it is needed to
interrelate it with other data indicators, which allow different "angles"
or "views," to identify a broader and integral visibility and impact of
scientific production in our contexts, either from journals or
repositories.


The indicator considers downloads, as the number of downloads reported by
the journal platform or repository (proofs); and time, as the number of
days online or "on air," which the document, article, book chapter, book,
paper, etc. has had (result of the difference in days between the date of
publication and the day of cut of analysis. The above operation shows
download level divided by the airtime = D / T Metrics).

application to a specific journal (RIB) or a repository (E-lis):

In conclusion, we have identified as a journal that we are visible and we
have impact, but we are not directly indexed in Web of Science and Scopus;
and as a repository, which is a key route for our contexts, considering the
characteristics of our scientific production.
