Add "profile" parameter to JSON-LD exporters

[pdurbin]

As we worked on #11045 we learned that we can disambiguate JSON-LD exporters by adding a "profile" parameter.

I've already created these pull requests to update external exporters:

• update media type to be more specific gdcc/exporter-croissant#7
• make media type more specific to RO-Crate #3 gdcc/exporter-ro-crate#4

For this issue I'm suggesting that we update the internal JSON-LD exporters...

• OAI_ORE FIXME: put "profile" URL(s) here
• schema.org (Schema.org JSON-LD) FIXME: put "profile" URL(s) here

... assuming there is an appropriate "profile" we can add (see FIXMEs above). As this is a backward-incompatible change, it should be documented in a future version of https://guides.dataverse.org/en/6.5/api/changelog.html.

In addition, we should update a future version of https://guides.dataverse.org/en/6.5/developers/metadataexport.html to provide some guidance on how the getMediaType() method can be used to assert the "profile" of JSON-LD exporters.

OAI_ORE FIXME: put "profile" URL(s) here

@stain hi! I was just looking at https://www.openarchives.org/ore/0.9/jsonld (you're listed first as one of the spec editors!) via https://www.openarchives.org/ore/ hoping to quickly find what JSON-LD "profile" parameter we should add to the media type for our OAI-ORE exporter. Is it http://www.openarchives.org/ore/terms/ perhaps? Help! 😅

The goal, as we talked about last week, when you presented Signposting to the Croissant working group, is to use the "profile" parameter to allow client to differentiate between various JSON-LD formats. Thanks!

schema.org (Schema.org JSON-LD) FIXME: put "profile" URL(s) here

@benjelloun hi! In the Croissant meeting the other day we said the "profile" we should use for Croissant is http://mlcommons.org/croissant/1.0 . What about for the original Schema.org JSON-LD format we've been using for Google Dataset Search? (The format we used until Croissant came along, I mean.) Do you know what the "profile" should be? Thanks!
