Abstract:	Browsing and accessing local and distributed datasets is an important aspect enabling Virtual Observatories. We present an example implementation of a data tree in the Astrophysical Virtual Observatory prototype tool. This is a dynamically built data tree containing information on image datasets, based on the IDHA data model. We show how the meta-data representation of the GOODS dataset in the AVO demo allows efficient data browsing and selection, and how the tree may be used to access local and distributed data. This capability is being developed in the framework of the CDS Aladin image browser, and AVO prototypes.
