What is the correct modeling of portal.getty.edu links?

[kasei]

Right now auction events have portal links using referred_to_by, but it seems like there might be some association between the sale catalog (the event's subject_of) and the portal WebPage:

pipeline/pipeline/projects/provenance/__init__.py

Line 181 in 1c93304

auction.referred_to_by = vocab.WebPage(ident=url)

{
  "type": "Activity",
  "_label": "Auction Event for F-A235",
  "referred_to_by": [
    {
      "id": "http://portal.getty.edu/books/inha_18072",
      "type": "LinguisticObject"
    }
  ],
  "subject_of": [
    {
      "id": "urn:uuid:0326dac7-8933-4949-8e37-47a2424efc7d",
      "type": "LinguisticObject",
      "_label": "Sale Catalog F-A235"
    }
  ]
}

Similarly for HumanMadeObjects, exact modeling of the portal link relationship needs to be confirmed.

pipeline/pipeline/projects/provenance/__init__.py

Line 809 in 1c93304

hmo.referred_to_by = vocab.WebPage(ident=url)

Agree -- we should confirm what the portal pages are thought to be. If they're all just copies of the catalogs, then they should be linked only from the catalogs. If there's also other documents that are mixed in, then we might need to link to them from other entities as well.

Portal links are now modeled as web pages:

    {
      "id":"http:\/\/portal.getty.edu\/books\/inha_17691",
      "type":"DigitalObject",
      "_label":"http:\/\/portal.getty.edu\/books\/inha_17691",
      "classified_as":[
        {
          "id":"http:\/\/vocab.getty.edu\/aat\/300264578",
          "type":"Type",
          "_label":"Web Page"
        }
      ]
    },

However, there's some uncertainty about how Arches can support the actual URL link, so it is included as both the id and _label.
