Sorry, I've been out of town since you sent this -- I'll re-focus my attention on it today

we need to make some changes to IdAS interfaces to represent changes to HOWL.
1. One of the main changes to HOWL is removing complex value from HOWL and replacing it with Entity(Node). So, we should remove IComplexAttrValue interface and replace all its references with IEntity.
2. Now Entity can contain subEntities, so we need to deside in which a way should an Entity return subEntities. It looks, subEntities should be returned as IAttributeValue by the methods getAttribute(..)/getAttributes(..). In other words, IEntity should extend IAttributeValue interface (so, both, IEntity and ISimpleAttrValue should extend the same interface).
2.1. Perhaps, we need to add isNode() and isSimpleValue() methods to IAttributeValue instead of isSimple() method.
3. We need to add isBlank() method to INode/IEntity (or, perhaps to INodeModel) initerface.
4. We need to reflect changes related to OWL1.1 like owl11:onDataRange (owl11:pattern, owl11:maxLength, owl11:minLength, etc). We need to add appropriate methods to IAttributeSimpleValueModel interface.
5. We need to remove interfaces related to metadata (ISimpleMetaValue, IComplexMetaValue, IHasMetadata, IMetadata, IFilterMetadataAssertion).
6 If you are going to remove IModel* intefaces, we need some interface which contains all those URIs which are required to navigate on your new model based on IEntity interface.
Thanks, Sergey Lyakhov
