Hi GaBriella,
on the UI perspective, I could not agree more. Using intermediate objects is
indeed not well supported right now.
For example,
ex:Person1
ex:memberOf [
a ex:Membership ;
ex:organization ex:Organization1 ;
ex:startDate "2005-04-12"^^xsd:date ;
ex:endDate "2009-11-08"^^xsd:date ;
] .
currently requires creating that Membership instance, then going into it to
fill in the dates.
And querying often requires using path expressions such as
?person ex:memberOf/ex:organization ?org .
The situation is complicated as there are variations of this, e.g.
ex:Person1Membership1
a ex:Membership ;
ex:member ex:Person1 ;
ex:organization ex:Organization1 ;
ex:startDate "2005-04-12"^^xsd:date ;
ex:endDate "2009-11-08"^^xsd:date .
I have some initial thoughts about better supporting editing blank nodes, but
none of that is fully fleshed out yet.
For these relationships, maybe a start would be to introduce some kind of dash
namespace extensions to
annotate the "intermediate" objects, so that a UI can pick up a suitable widget
such as a tabular viewer and editor.
I wonder if anyone has input or similar requirements.
Is my assumption right that in many of these relationships, there is at most a
handful of properties (such as startDate
and endDate), allowing tabular input and rendering?
