Subject: LP#1423585 Add Open Graph Protocol markup to TPAC
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=efd0c1f9cb4f971658f06cade9b052f1710229c7;p=evergreen%2Fmasslnc.git

LP#1423585 Add Open Graph Protocol markup to TPAC

Very simplistic markup for now, just the basic http://ogp.me
requirements of title, url, image, and type (and we're reusing
the schema.org type in the short term).
