Status of Document:	This is a DCMI Working Draft
Description of Document:	This document discusses the design choices involved in designing applications for different types of interoperability. At Level 1, applications use data components with shared natural- language definitions. At Level 2, data is based on the formal-semantic model of the W3C Resource Description Framework. At Level 3, data is structured as Description Sets (records). At Level 4, data content is subject to a shared set of constraints (described in a Description Set Profile). Conformance tests and examples are provided for each level. The Working Draft represents work in progress for which the authors seek feedback.

Introduction
Level 1: Shared Term Definitions
Level 2: Formal Semantic Interoperability
Level 3: Description Set Syntactic Interoperability
Level 4: Description Set Profile Interoperability

Introduction

The evolving assumptions which over the past decade have led from fifteen elements [RFC2413] to the Singapore Framework for Dublin Core™ Application Profiles [DCAP] can be captured in a layered model of interoperability. The model of levels presented here addresses the need felt in many communities to position various projects with various degrees of interoperability with Dublin Core™ but lacking an appropriate terminology.
