[garza-utsa]

meta : https://walledev.it.utsa.edu/entity/open.act?id=7f4cb28381736a1b003cf7c3ca483ffd&type=format

meta-blog: https://walledev.it.utsa.edu/entity/open.act?id=3d8a0b3281736a1b76f225b306213737&type=format

meta-faculty-profile: https://walledev.it.utsa.edu/entity/open.act?id=3d8a419081736a1b76f225b3b58670fa&type=format

have been added/adjusted:

• /images/default-meta.jpg will be shared if it exists on the existing college site
• otherwise, for blog, will try and use image1
• otherwise (lastly), will default to the generic www.utsa.edu/_files/monument340.jpg

meta-faculty-profile will attempt to autogenerate a description based on the faculty's name, title and primaryDepartment, unless a meta description on the profile page already exists

had to push these to Walle to actually test with external tools, so lets see if I broke anything...
