Hi Kevin, Um, no, as you have probably surmized, @Value is not currently supported.
There are two reasons: 1. for the Wicket viewer, a custom component would need to be developed to render the value by some means or other 2. for DataNucleus, an implementation of its JavaMapping is required [1,2,3] 3. the field may need additional DN annotations when in the domain model [4] All of this makes our @Value annotation pretty redundant. (There might, still, be one part of Isis that has a vestigial dependency on the value semantics facets; I could look up the details to double check if you want to pursue).

I have a "Location" value semantics provider that represents a Location as 3 integers ("x;y;z"), but it does not seem to be used as I expect. Do I need to do anything special, other than have the provider declared? @Value(semanticsProviderClass = LocationSemanticsProvider.class) public class Location implements Serializable { ... } After adding a "Location" property to the SimpleObject generated from the archetype I don't see it being picked up and used by DataNucleus... @javax.jdo.annotations.Column(allowsNull = "true", length = 40) @Property(editing = Editing.ENABLED) @Setter @Getter Location location; The to/from string methods of the LocationSemanticsProvider are being called, but the property is not being persisted... There is no corresponding column in the created table.. 20:38:32,414 [Schema main DEBUG] CREATE TABLE "simple"."SimpleObject" ( "id" BIGINT GENERATED BY DEFAULT AS IDENTITY, "map" VARCHAR(255) NULL, "name" VARCHAR(40) NOT NULL, "notes" VARCHAR(4000) NULL, "version" TIMESTAMP NOT NULL, CONSTRAINT "SimpleObject_PK" PRIMARY KEY ("id") ) Cheers, Kevin
