| RE: [higgins-dev] Higgins data model for attribute values |
|
Good question, Jim. My assumption would have
been that if an Attribute allows multiple values, they all would be of the same
data type. Is there a use case for an Attribute having multiple values with
different data types? =Drummond From:
higgins-dev-bounces@xxxxxxxxxxx [mailto:higgins-dev-bounces@xxxxxxxxxxx] On Behalf Of Jim Sermersheim Before
addressing bug #190594, I need to know more about what the Higgins data model
allows in an attribute's instance data. In
IdAS, my understanding is that a Digital Subject may have 0..1 occurrence of a
particular Attribute, and that an Attribute may have 1..N occurrences of a
particular type of Value. It's
my understanding that each of an Attribute's values must be of the same data
type, but that restriction isn't obvious to me in the Higgins OWL, and in fact,
the opposite is reflected in the IdAS APIs. In IdAS, one can state the
data type of each value they add to an attribute. So,
we need to agree on the Higgins data model regarding the types of attribute
values. Should the Higgins data model dictate that they all be of the
same type, or should it allow their types to be mixed? |
