Thank you. All of the members of the EACWG are very pleased to release
it at last.
EAC-CPF does accommodate "localization," though not as permissively as
the technique described below. There are two principal ways of
extending the EAC-CPF. The first method is through the use of the
@localType (anyURI), which can be used to make the semantics of many
of the EAC-CPF tags more specific. The second method is to use within
<description> the <localDescription> or <localDescriptions> (which may
contain one or more <localDescription>. Both require the @localType.
These can be used to extend the EAC-CPF using a type or category of
description not accommodated in ISAAR(CPF) and EAC-CPF. "Nationality"
is a good example. It is not specifically addressed in either
ISAAR(CPF) and EAC-CPF because there is no international consensus on
the what "nationality" is. Nevertheless, at least one member of the
EACWG represents a national context within which the category is
considered meaningful and useful.
We did not accommodate a more permissive approach simply because we
wanted to encourage consistency and uniformity in practice based on an
international standard, ISAAR(CPF), in order to encourage the
international sharing of authority records. "Too much" diversity
(unpredictability) makes sharing and aggregating difficult.
As for extensions outside of what is accommodated, I think this is
perfectly acceptable in local systems, as long as what is shared
outside of the local systems conforms to EAC-CPF.
In the very near future, EAD will be reviewed and revised. I suspect
your suggestion concerning extensibility will be discussed!
