Just followed this test as an example solid-crud.test.ts

const bookmark = await BookmarkModel.at(
  "https://my-pod.solidcommunity.net/bookmarks/"
).create({
  label: "label",
  link: "https://podpro.dev/",
});

bookmark.topicRelationship().create({
  topic: "https://podpro.dev/test",
});

bookmark.save();

but the result was not as expected (create Topic and attach it into the bookmark)

result:

@prefix : <#>.
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>.
@prefix xsd: <http://www.w3.org/2001/XMLSchema#>.
@prefix bookm: <http://www.w3.org/2002/01/bookmark#>.
@prefix pod: <https://podpro.dev/>.
@prefix crdt: <https://vocab.noeldemartin.com/crdt/>.

:it a bookm:Bookmark; rdfs:label "label"; bookm:recalls pod: .

:it-metadata
    a crdt:Metadata;
    crdt:createdAt "2023-11-13T13:49:13.518Z"^^xsd:dateTime;
    crdt:resource :it;
    crdt:updatedAt "2023-11-13T13:49:13.518Z"^^xsd:dateTime.

there is no document for topic at all

I tried creating the topic first and the attach it's URL to bookmark in attributes:

const topic = await TopicModel
  .at("https://my-pod.solidcommunity.net/topics/")
  .create({ label: "soukai-solid" })

await topic.save()

const bookmark = await BookmarkModel.at('https://my-pod.solidcommunity.net/bookmarks/').create({
  label: "label",
  link: "https://podpro.dev/",
  topic: topic.getAttribute("url")
});

bookmark.save()

this time the result was 2 documents[bookmark and topic] with a link from bookmark to topic
