			• Earliest schemas were largely conceptual in nature: – e.g. Pittsburgh BAC model, Cedars outline specification, OCLC/RLG WG I • Gradually moving towards a more practical focus: – e.g., VERS, NLNZ, METS, PREMIS WG – Convergence on XML (DTDs and Schemas) • But there is an urgent need for all this practical experience to be shared – e.g., published schemas, advice on implementation, etc.
