+  <abstract>
+<p> We introduce <i>XML Access Modules (XAMs)</i>, a step towards physical data independence in XDBMSs. A XAM describes, in an algebraic-style formalism, the information contained in a persistent XML storage structure, which may be a storage module, an index, or a materialized view. The set of XAMs describing the storage is used by the optimizer to build data access plans. Using XAMs, a change to the storage (adding or removing a storage structure) is communicated to the optimizer simply by updating the XAM set.
+One of the most useful XAM features is the ability to model indexes whose ``keys'' and ``values'' may be complex combinations of XML structure and values. We present the algebraic XAM foundations, with a particular focus on its support for indexes.

+<p> We demonstrate ULoad, an XML storage tuning tool, which is a step towards achieving physical data independence for XML. ULoad is meant to help the database administrator (DBA) in choosing the persistent XML storage and indexing modules best suited for a given dataset, and workload, thus achieving our flexibility and extensibility requirements.
+ 
+Given a document to store, and a query workload, ULoad: allows the DBA to choose, customize, and apply some storage and indexing models, picked among a large set of existing ones; lets the DBA define her own specialized persistent structures; presents to the DBA the query execution plans (QEPs) for the workload queries, on the storage model chosen, and their costs; and may propose a storage adapted to the data and workload, based on a cost-driven search.
+ 
+At the core of ULoad lies a novel algebraic formalism (with a simple graphical representation), called <i>XML Access Modules (XAMs)</i>, describing the information contained in a persistent XML storage structure.  </p>
