Lifecycle Metadata for Digital Objects September 4, 2002 Overall framework: OZ meets WC3

Anne Gilliland-Swetland, “Setting the Stage” I Content: library focus on access Context: archives focus Structure: of objects and groups

Setting the Stage II Types of metadata –Administrative –Descriptive –Preservation –Technical –Use

Setting the Stage III Attributes –Source of metadata (internal or external) –Method of metadata creation (auto or manual) –Nature of metadata (lay or expert) –Status (static or dynamic) –Structure (structured or unstructured) –Semantics (controlled or uncontrolled) –Level (item or collection)

Setting the stage IV Life cycle –Creation and versioning –Organization –Searching and retrieval –Utilization –Preservation and disposition

Gail Hodge, “Metadata Made Simpler” Purposes of metadata –Resource discovery –Organizing resources –Interoperability –Digital Identification –Archiving and preservation

Metadata Made Simpler II Metadata element sets used in libraries –Dublin Core –Global Information Locator Service (GILS) –Text Encoding Initiative header –EAD –Visual Resources Association Core Categories –ONIX international

Metadata Made Simpler III Frameworks for Interoperability –UKOLN Schemas –RDF –OCLC CORC –INDECS Metadata registries

Sue McKemmish, “Yesterday, Today, and Tomorrow” Application of records continuum Integration of continuum process Importance of continuum (compare to life cycle) –Governance and accountability –Collective memory and identity –Records as assets –Can be expanded to the idea of any kind of information, not just records –Does not require centralized custodianship –Heals records manager/archivist split

“Yesterday” II Four dimensions of the continuum (all active through life of record): Create: actors, acts, documents, trace Capture: reliable recordkeeping systems Organize: entire recordkeeping regime Pluralize: social/archival context for access Does all this imply a public context?

Frank Upward, “Structuring the Records Continuum” “Postcustodiality” Registrar/archivist role Collapse of confidence in physical custody “Premodern” archives ideas: archival bond, archival limes

Structuring the Continuum II Postmodern archives ideas: –Records continuum unifying recordkeeping –Records as logical entities, not physical –Integration of recordkeeping into business process –Archival science the foundation of recordkeeping knowledge

Identity Evidentiality Trans- actionality Recordkeeping containers Dimension 1 CREATE Dimension 2 CAPTURE Dimension 3 ORGANISE Dimension 4 PLURALISE Actor(s) Trace Transaction [Archival] Document Unit(s) evidence Activity record(s) Organisation Corporate / Individual Memory Function archive Institution Collective Memory Purpose Archives The Records Continuum c.Frank Upward, all rights reserved

Structuring the Continuum III Recordkeeping axis –Document –Record –Archive –Archives Evidence axis –Trace –Evidential record –Organizational memory –Collective memory Transactional axis –Act –Activity –Function –Purpose Identity axis –Actor –Workgroup –Organization –Institution

SPIRT Model Conceptual Modelling Literary Warrant Analysis Mapping Metadata Metamodelling Empirical Instantiation Australian Metadata Standard: 20 elements

XML in 10 Points XML is for structuring XML looks like HTML XML is text for computers XML is purposely verbose XML is a family XML is only partly new XHTML->XML XML is modular XML is base for RDF, Semantic Web XML is free, universal, supported

Bosak and Bray, “XML and the second-generation Web” Tags for meaning, not show SGML: tag pairs and nesting Unicode and web services Permanent URL databases Webmasters will be programmers DTD repositories XSL for style

Berners-Lee, “Web architecture from 50,000 feet” Universal information utility Universal addresses Universal language (XML) Action repositories (web services) Description repositories (DTDs, namespaces) Logical structure for documents (RDF) makes them operable
