I am reluctant to respond like this. However, as far as I can tell you have been repeatedly posting the same thing every 2~3 days for at least three times to the list this week.

Best wishes,

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

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; 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).

Look up the following article to know more about this proposal and application to a specific journal (RIB) or a repository (E-lis):

"Somos visibles y tenemos impacto. Análisis desde datos de acceso abierto, altmetrics y otros de la Revista Interamericana de Bibliotecología".

“We Are Visible and We Have Impact. Open Access Data Analysis, Almetrics and Others of the Revista Interamericana de Bibliotecología”
(In Spanish, and soon in English)

Authors: Alejandro Uribe-Tirado, Juan Camilo Vallejo-Echavarría y Darío Alexander Betancur-Marín
DOI: 10.17533/udea.rib.v39n3a04

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.
