# properties.identifiers.$comment
Some identifiers have specific properties e.g the `issn` property for
the `Periodical` type. These should be used in preference to this
property which is intended for identifiers that do not yet have a
specific property. Identifiers can be represented as strings, but
using a `PropertyValue` will usually be better because it allows
for `propertyID` (i.e. the type of identifier).
