  3. Project Objectives • Virtual Data Grid Services • Ingestion Workflow Prototype • XML Schema for SIP • Data Description Languages

  4. Virtual Data Grid Services • Archival services provided by GTRI • File System Packaging with NARA Metadata in XML DTD Manifest • File type identification • File conversion • File viewers and readers • Information Extraction • Services described in WSDL • Register Services • Discover and request archival services • Demonstrate on SLAC science data

  5. Ingestion Workflow Prototype • Addressing issues similar to the Producer-Archive Interface • Provides data to NARA based on a prior agreement with Records Creator • Consists of metadata server and an ingestion client • Provides initial arrangement, context and metadata • NARA • validates digital objects and metadata, • stores objects in a digital repository and • stores metadata in a catalog • Demonstrate on SLAC science data.

  6. XML Schema for SIP • Modifications of MET to meet NARA records management requirement. • Client generates and receive METs documents. • Client contacts Metadata server using X.509 certificates. • Metadata server stores METS items in a MySQL database. • Metadata server manages certificates. • NARA server verifies metadata integrity against schema and specification document.

  7. Data Description Languages for Data Grids • BinX M. Westhead and M. Bull. Representing Scientific Data Sets on the Grid, EPPC, University of Edinburgh, Jan 2003. • DFDL M. Westhead. Data Format Description Language – Primer, Global Grid Forum Data Format Description Language Working Group
