    dcterms:description """an **index-card** is
a metadata record about a specific thing.

that thing is called the "focus" of the index-card and is identified by a "focus IRI"
-- any thing may be identified by multiple iris, but choose one within an index-card
(and perhaps include the others with `owl:sameAs`)

the metadata about the thing is a quoted [rdf graph](https://www.w3.org/TR/rdf11-concepts/#data-model)
in which every triple is reachable from the card's focus IRI
following predicates as directed edges from subject to object.

there is not (yet) any size limit for an index-card's metadata,
but it is intended to be small enough for an old computer to use naively, all at once
(let's start the conversation at 4 KiB -- might be nice to fit in one page of memory)

### jsonapi representation
the index-card's `resourceMetadata` property contains a quoted graph, independent
of the rest of the response.

when represented as `application/vnd.api+json` (jsonapi), the `resourceMetadata` attribute
contains a json object that has:

* `@id` with the focus IRI
* `@type` with the focus resource's `rdf:type`
* property keys from [OSFMAP](https://osf.io/8yczr) shorthand (each corresponding to an IRI)
* property values as lists of objects:
  * literal text as `{"@value": "..."}`
  * IRI references as `{"@id": "..."}`
