Dryad provides general statistical information about the number of data files and data packages (the complete collection of files associated with an article) in the repository, as well as information about how many times each data package has been viewed and how many times each component data file has been downloaded. These statistics provide an indication of the amount of use that data packages and files receive, and give an overall snapshot of Dryad's growth. Authors can use these statistics as a measure of the usage of their data in Dryad.
To see the overall Dryad statistics of total Dryad content, just visit the Dryad home page. One this page, near the top, is a sentence that shows the current date and how many data packages and data files are in Dryad at that point in time. This sentence also gives the number of distinct journals represented in Dryad. For an example, see the screenshot below.
Dryad also provides usage statistics for each data package and each data file within Dryad. On each data package landing page, the number of views is displayed for the data package, and the number of downloads for each component data file. See the screen shot below for an example.
The Dryad statistics build on the statistics package provided by DSpace. More information about the implementation can be found on the Statistics Technology page.
