Graphs of repository statistics

OpenDOAR has added 16 new graphs to show the state of the repositories in the directory.  From today's announcement:

OpenDOAR is pleased to announce the release of new statistical graphs for its database.  There are 16 different charts in all, including:

  • Repositories or Repository Organisations by Continent or Country
  • Usage of Open Access Repository Software Platforms
  • Open Access Repository Types
  • Repository Operational Statuses
  • Most Frequent Content Types
  • Most Frequent Languages
  • OpenDOAR Subjects
  • Grades for Metadata Re-use policies, [Full Text] Data Re-use policies, etc.
  • Growth of the OpenDOAR Database

By default the charts cover the full OpenDOAR database. However, as the graphs are an add-on to the existing 'Find' page, you have the option to view results as charts whatever search you do. For instance you could use the country filter to see how the "United States" and "Europe" compare. Or you could see how usage of GNU EPrints differs from DSpace and Bepress....

We hope the charts will be useful for advocacy purposes. We are therefore happy for people to include the charts in their own websites, and we provide the necessary HTML source code. The charts are dynamic, so you always see the latest data.

PS:  These are useful, especially (for my purposes) the chart of the growth in the number of repositories listed in the directory.  OpenDOAR doesn't chart the number of items on deposit in each listed repository, as ROAR does, and neither directory (yet) makes it easy to learn the total number of items on deposit in all the listed repositories.
