In preparation for the next Roadmap Committee meeting, an update:
On the recommendations from the Committers' Call, Islandora Badges has been broken out into submodules, for better integration with the existing Islandora Altmetrics, as well as simplified addition of new badges.
A PR is also out, merging soon, adding an oaDOI submodule - takes an object's DOI, and if there is (a) no PDF datastream already, and (b) a fulltext link is available via the oaDOI API, generates a block linking to the free fulltext PDF.
