#AlternateOrder ⇒ RDF::Vocabulary::Term (readonly)

An AlternateOrder is an alternate ordering of its parent’s members. It should only order the parent’s members, and otherwise has all of the features of ordering (some members may be omitted from the order, members may appear more than once in the order, etc.).

Returns:

  • (RDF::Vocabulary::Term)

def AlternateOrder
  @AlternateOrder
end

#Collection ⇒ RDF::Vocabulary::Term (readonly)

A Collection is a group of resources. Collections have descriptive metadata, access metadata, and may links to works and/or collections. By default, member works and collections are an unordered set, but can be ordered using the ORE Proxy class.

Returns:

  • (RDF::Vocabulary::Term)

end

#File ⇒ RDF::Vocabulary::Term (readonly)

A File is a sequence of binary data and is described by some accompanying metadata. The metadata typically includes at least basic technical metadata (size, content type, modification date, etc.), but can also include properties related to preservation, digitization process, provenance, etc. Files MUST be contained by exactly one Object.

Returns:

  • (RDF::Vocabulary::Term)

#fileOf ⇒ RDF::Vocabulary::Term (readonly)

#hasFile ⇒ RDF::Vocabulary::Term (readonly)

Links to a File contained by this Object.

  @hasFile
end

#hasMember ⇒ RDF::Vocabulary::Term (readonly)

Links to a subsidiary Object or Collection. Typically used to link to component parts, such as a book linking to a page. Note on transitivity: hasMember is not defined as transitive, but applications may treat it as transitive as local needs dictate.

Returns:

  • (RDF::Vocabulary::Term)

end

#hasRelatedObject ⇒ RDF::Vocabulary::Term (readonly)

Links to a related Object that is not a component part, such as an object representing a donor agreement or policies that govern the resource.

Returns:

  • (RDF::Vocabulary::Term)

#memberOf ⇒ RDF::Vocabulary::Term (readonly)

  @memberOf
end

#Object ⇒ RDF::Vocabulary::Term (readonly)

An Object is an intellectual entity, sometimes called a “work”, “digital object”, etc. Objects have descriptive metadata, access metadata, may contain files and other Objects as member “components”. Each level of a work is therefore represented by an Object instance, and is capable of standing on its own, being linked to from Collections and other Objects. Member Objects can be ordered using the ORE Proxy class.

Returns:

  • (RDF::Vocabulary::Term)
