  • Lifecycle Metadata for Digital ObjectsOctober 4, 2004Creation Metadata

  • Review class metadata sets: What categories do they fill?Dublin CoreEADFRBRINDECSMARC/MODSMETSMIX/NISOMPEG21NLM JournalOCLC/RLGONIXPRISMRKMSTEI LiteVRA Core

  • What happens at file creation?ConsciouslyYou place into the file everything you think it needs in order to be usefulYou save it with a file name that will help you find it again (you hope)UnconsciouslyMetadata is added using environmental informationMetadata is added using information elicited from you

  • Metadata from creating app (Word 2000 Statistics)

  • Metadata from creating app (Word 2000 General)

  • Metadata controlled by the user (Word 2000 Summary)

  • Metadata controlled by the user (Word 2000 Custom)

  • Viewing Word Metadata in XMLAdd relevant metadata to your Word document as outlined aboveIf you have Word 2003, save the document as XMLOpen the document in an XML editorIf not, save the document as HTMLView the document in Notepad or another ASCII editor or view source from the HTML document displayed in a browser

  • The future of XML in Word?Word already provided XML markup of its Document Properties and Custom Document Properties metadata; in Word 2003 a native (and patented) XML schema is used.Several vendors made plugins for making older Word documents into XML documents:eXportXML from Schultz: a template installed into Word using a macroXfinity Author Wx from B-Bop: makes Word into an XML editor for ordinary documentsWorX SE from Xyenterprise: Word as XML editor or creator of XML objects

  • Future of XML at MicrosoftXML and the whole model of the way the web works are becoming part of the emerging Microsoft operating environment from servers to desktopNote already a move to a standard IE interface for system functionsPresently provides tools to programmers under Information Bridge framework to allow connecting XML documents created by Microsoft programs via metadata elements to web services Creation metadata thus vital to this whole scheme

  • [non-Microsoft] Uses of creation metadataEstablishing prior art for an inventionIdentifying who knew what and whenShowing how an object fits into the larger scheme of things (preserving the archival bond)Keeping track of versions of an objectProviding assurance of reliability: that the object is what it purports to beAnchoring the object in the place and time of its origin

  • Placement of creation metadataSame options as for all metadataEmbedded within the object (Word metadata)Wrapped around the object (object is embedded in metadata document: Word document containing metadata embedded in XML document extracting reliability metadata)Captured, communicated, or kept separately from the object (non-text objects but not only them)

  • UBC Creation Metadata IA word on diplomaticsThe notion of a complete recordMediumContentFormPersons (author, writer, addressee, creator)ActsArchival bondTransmission (intent, capability, success)

  • UBC Creation Metadata IIElements of intellectual form inside the record:Date (time of transmission and receipt; place of transmission)Superscription or attestation (author/originator)Inscription (all addressees and receivers)Title and/or subjectDisposition/purpose (the intention of the record)

  • UBC Creation Metadata IIIThe notion of reliable record; must in addition to completeness have:Document profile as container for the objectDate available (created or received)Time available (created or received)[Date and time of further transmission]AuthorAddresseeSubject [classification code, registry number]

  • DoD 5015.2 Recordkeeping Standard: AssumptionsNote that 5015.2 assumes an entire detailed recordkeeping system that fully accounts for all records at the series, folder, and individual levelThe file plan defines the recordkeeping system; the schedule is applied to entities defined in the file plan

  • DoD 5015.2 Recordkeeping Standard: record metadata (*=mandatory)Unique identifier*Supplemental marking listSubject/Title*Media type*Format*Date filed*Publication date*Date receivedAuthor/Originator*Addressee*Other addressees*Originating organization*LocationVital record indicatorVital record review/update cycle*User-defined fields

  • DoD 5015.2 email metadata mappingSender (Author/Originator)Primary addressees (Addressee)Other addressees (Other addressee)Date/time sent (Publication date)Date/time received (Date received)Subject (Subject/Title)

  • Date/time and persons: vital to records reliabilityWithout date/time, not possible to manage records by date: cutoffs, retention, destructionWithout persons (author, recipient, creator), nobody would careWithout hierarchical set of data categories, no structureNote dependence on systems in which records creation are embedded

  • What about non-text objects?Creation metadata for non-text objects covers much the same ground:Information about occasion of creationInformation about creator, intention, receiverInformation about the object itselfMany kinds of non-text objects:Images, still and movingSoundMultimedia

  • Connecting metadata to a non-text objectObject is kept in specifically-defined file structureFile name/ID is crucial to the connectionXLink is used to connect the two using a series of XML attributes:
