Preservation metadata requirements for repositories: a project of the Australian Partnership for Sustainable Repositories (APSR) -- APSR aims to establish a centre of excellence in sustainable digital resource management and partner universities are developing demonstrator repositories built on sustainability principles. This paper presents the work of a project commissioned by APSR to specify requirements for the collection of metadata needed for long term continuity of access to digital collections. The project was called PRESTA (PREMIS Requirements Statement) but it took a broader view than PREMIS alone. The MetaArchive of Southern Digital Culture will discuss the first two years of deliverables (2004-2006) for their three year partnership for establishing a collaborative digital preservation network for southern cultural heritage materials.
