CIROH Portal: Presentation Tab Additions

This collection is used to provide backwards compatibility for presentations that were uploaded to HydroShare prior to the creation of CIROH Portal's \"Presentations\" tab (and to manage ordering of back-uploaded presentations).
If you'd like to add your presentation there, simply:
- Add the \"ciroh_portal_presentation\" keyword to your resource.
- (Optionally) Add the \"pres_path\" extra metadata field in your resource. It should contain the path to a PDF file that will be embedded
- (Optionally) Add the \"page_url\" extra metadata field in your resource. It should contain the URL of a video recording or similar resource for your presentation.

Alternatively, the upload interface on CIROH Portal will also work: https://portal.ciroh.org/contribute?current-contribution=presentations
