I've had a look, and the only bits I think we can use as-is are the
cerif:InfrastructureEntity class[1] and its subclasses. The
relationships are all first-class (e.g.
isLinkedByOrganisationUnit/linksToOrganisationUnit), and so seem
overkill in this context.

Other bits of it reproduce other vocabs (vcard, frbr, event, dc), and
seem unnecessary.

Cool. I'll get back to you when I'm ready.

Presumably, a person can use it if they're a member of any of the
devisions/orgs.

We're straying into GoodRelations territory here, i.e.

:universityOfOxford gr:offers :useOfEquipment .

:useOfEquipment a gr:Offering ;
  rdfs:label "Available for use by members of the University of Oxford, …"
  tio:includes [
    a tio:TicketPlaceholder ;
    tio:accessTo :equipment ] ;
  gr:eligibleCustomerTypes :oxfordMembers, :membersOfUKHEIs,
:commercialUsers

In this case we define :oxfordMembers locally, and stick the others in a
controlled vocab somewhere. In the absence of a gr:priceSpecification,
then people should assume the price is negotiable/unspecified. If it's
free:

:useOfEquipment gr:priceSpecification [
  a gr:PriceSpecification ;
  rdfs:label "free"@en ;
  gr:hasCurrencyValue 0 ;
  gr:validThrough "2012-12-31T23:59:59"^^xsd:dateTime ] .

For simplicity we could offer a shortcut, e.g.:

:equipment ex:useOfferedTo :oxfordMembers, etc.

or:

:equipment ex:useOfferedTo :membersOfOwningInstitution, etc.

though this wouldn't allow specifying prices, and I'm not sure I like
the latter as ":joeBloggs ex:member :membersOfOwningInstitution" is
undefined.
