Commit 2e23ab5

• Changes physical collection name and description as discussed in the 2018-08-20 meeting
• Is sort of a stopgap measure. Still haven't figured out a mechanism to include links to dataset parts other than current. Would be happy to implement such a mechanism but need help. As noted in comment, in an effort to do this I added even more variables to the already long list at the top of the stylesheet.

@gerontakos Hello Theo-- I wanted to let you know to please not pull or use my current version of the rdf2rdfa transform. It needs more work--links in the collection description are not being generated correctly. Sorry about this--thank you!

@gerontakos

At this point, the rdf2rdfa transform:

• Includes mechanism for generating links to dataset parts other than current part
  • These parts are presented in the order matching the order of DOIs for each class
• Correctly generates links to alternate serializations for current dataset part

I'm sure that there is plenty of room for improvement in the way I have variables, etc. set up.
However, I believe that everything works and that we are ready to output and replace current landing pages with new and improved HTML/RDFa for the AYP datasets once today's SPARQL work is finished up.

Still to-do:

• Add an "About this dataset" section with links to previous versions.

Even though, it seems that we will want to create and post new HTML today, even though this section is not yet complete?
