Since solid uses WebID Profiles does anyone see problem with simply registering in type index container for foaf:Person
profile.registerType(solid.vocab.foaf('Person'), 'https://storage.example/civr5dp8p0000n5prdue8qwip/civr5ft5z0000nppr6mrb0i1q/', 'container', true)

so in this container would keep a copy of WebID profiles of all the people i want to bookmark
so each resource in that container would have <> foaf:primaryTopic {webid} just as WebID Profile it keeps copy of

profile.registerType(solid.vocab.foaf('PersonalProfileDocument'), ...)
but that dosn't work if i want register containers to collect copies of profiles for groups, projects, organizations, places, events, books, movies ... anything

registering types of things that documents describe seems more practical then trying to register types of documents

vcard:VCard doesn't seem to distinguish the thing from the document as foaf:Person and foaf:PersonalProfileDocument do
The vCard class is equivalent to the new Kind class, which is the parent for the four explicit types of vCards (Individual, Organization, Location, Group)
above suggests that vcard:Individual matches foaf:PersonalProfileDocument and not foaf:Person

elf Pavlik @elf-pavlik Nov 20 15:57
and if social graph should rely on vcard then WebID and Solid WebID Profiles Spec should also use vcard not foaf

:VCard a owl:Class ;
owl:equivalentClass :Kind .
:Individual a owl:Class ;
rdfs:subClassOf :Kind ;

I wonder what @deiu tied to do with https://github.com/linkeddata/contacts/blob/ac9f0888fea289b5645033f1533677d78a7fe932/app/app.js#L333

g.add($rdf.sym(''), RDF('type'), VCARD('VCard'));
g.add($rdf.sym(''), VCARD('hasIndividual'), $rdf.sym('#card')); // hasIndividual doesn't exist!
g.add($rdf.sym('#card'), RDF('type'), VCARD('Individual'));

The property owl:equivalentClass is used to indicate that two classes have precisely the same instances.

given turtle excerpt from vcard ontology describing relationship between vcard:VCard, vcard:Kind and vcard:Individual I underatand that each instance with type vcard:Individual has also type vcard:VCard
what then solid-contacts means by solid-hacks:hasIndividual

<> a vcard:VCard ;
  solid-hacks:hasIndividual <#card> .
<#card> a vcard:Individual .

Stating that Person and Human are equivalent amounts exactly to the same as stating that both Person is a subclass of Human and Human is a subclass of Person.
