  • development of management processes and systems to support the aggregation of non-heterogeneous record-oriented or statement-oriented, item-level metadata from diverse collections via OAI-PMH or API; normalizing it, augmenting it, and generally improving the quality; then re-serving the resulting resource-oriented, item-level, aggregated metadata from a central metadata repository for use in building resource-discovery services
  • transformation and mapping of legacy library data to current web data standards (such as Dublin Core, RDA or BibFrame), with the emphasis on repurposing, re-using and extending metadata using Semantic Web technologies
  • strategic and tactical planning for building, sharing, distributing, and maintaining metadata
  • vocabulary development, distribution and maintenance using the Open Metadata Registry (OMR) ( or other management technology
  • planning and implementation of the Open Archives Initiative Protocol for Metadata Harvesting, for either harvesting/aggregation or exposure of metadata
