  2. Content Packaging: The Alternatives Resource aggregation “The process of gathering together resources; the results can be used in one or more applications, such as transmission, storage, and delivery to users” • Dublin Core Abstract Model • MPEG-21 DIDL • IMS-CP herve@essex.ac.uk

  3. Content Packaging: interoperability RAMLET IEEE Resource Aggregation Model for Learning, Education and Training • METS: mapping complete • IMS Content Packaging: mapping complete • Work on MPEG 21 DID almost done • Work on human readable description started herve@essex.ac.uk

  4. optional METS Header optional optional optional Descriptive metadata Administrative metadata Behavioral metadata required optional File Inventory Structure map The METS Model: Overview herve@essex.ac.uk

  5. The METS Model Header METS document: administrative metadata • Author/agent & agent role • Alternate identifiers for METS document • Creation and update dates and times • Status Behaviours • “Linking behavior definitions and program code with digital content and with associated descriptive and administrative metadata” herve@essex.ac.uk

  6. METS: a simple diagram herve@essex.ac.uk

  7. Descriptive Metadata herve@essex.ac.uk

  8. Descriptive Metadata It’s easier with maps Descriptions for: Collection, object, file, sub file • Dublin Core • MODS • MARC 21 (MARC XML) Mappings: • DC Simple to MODS • MARC to MODS • MODS to MARC herve@essex.ac.uk

  9. Descriptive Metadata Simple Dublin Core to MODS herve@essex.ac.uk

  10. Descriptive Metadata MODS to MARC21 herve@essex.ac.uk

  11. Descriptive Metadata Available transformations • MARCXML to MODS • MODS to MARCXML • Dublin Core to MODS • MODS to Dublin Core • MODS Version 2.0 to MODS Version 3.0 • MODS 3.0 to simple HTML display herve@essex.ac.uk

  12. Administrative Metadata herve@essex.ac.uk

  13. Technical Metadata herve@essex.ac.uk

  14. Technical Metadata MIX: technical metadata for still images in XML • Derived from NISO Z39.87 • Technical Settings • Image creation: technology & processes herve@essex.ac.uk

  15. Technical Metadata: MIX !-- NISO Section 6 --> <BasicDigitalObjectInformation> • Identifiers, Formats, Compression, Checksums !-- NISO Section 7 --> <BasicImageInformation> • Height, Width, photometric interpretation, color space <!-- NISO Section 8 --> <ImageCaptureMetadata> • Source dimensions, scanner/camera settings & software, gps <!-- NISO Section 9 --> <ImageAssessmentMetadata> • Bits per sample, color encoding etc etc herve@essex.ac.uk
