Lifecycle Metadata for Digital Objects

October 23, 2006

Creation Metadata

what happens at file creation
What happens at file creation?
  • Consciously
    • You place into the file everything you think it needs in order to be useful
    • You save it with a file name that will help you find it again (you hope)
  • Unconsciously (or unwillingly)
    • Metadata is added using environmental information
    • Metadata is added using information elicited from you
viewing word metadata in xml
Viewing Word Metadata in XML
  • Add relevant metadata to your Word document as outlined above
  • If you have Word 2003, save the document as XML
  • Open the document in an XML editor
  • If not, save the document as HTML
  • View 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
The future of XML in Word?
  • Word has already provided XML markup of its Document Properties and Custom Document Properties metadata for several versions back
  • In Word 2003 a native (and patented) XML schema was used
  • In Office 2007 XML will be systematically included in the form of a configurable RM template
future of xml at microsoft
Future of XML at Microsoft
  • XML and the whole WC3 model are becoming part of the emerging Microsoft operating environment from servers to desktop
  • Note move to a standard IE interface for system functions
  • Steps ongoing to build 5015.2-like records management functions into office suite as part of the Enterprise Content Management architecture based on the SharePoint Portal Server, so as to get business from governments
  • Creation metadata thus vital to this whole scheme
open office metadata
Open Office metadata
  • Note Open Office metadata itself is just as complex as the new Microsoft standard
  • OO object is packaged as a group of files (see specification, pp. 541-545: the package is a zip file with an XML manifest file containing a list of files and their types)
  • This means also being concerned with zip file format standard, compression, etc. etc.
non microsoft uses of creation metadata
[non-Microsoft] Uses of creation metadata
  • Establishing prior art for an invention
  • Identifying who knew what and when
  • Showing how an object fits into the larger scheme of things (preserving the “archival bond”)
  • Keeping track of versions of an object
  • Providing assurance of reliability: that the object is what it purports to be
  • Anchoring the object in the place and time of its origin
placement of creation metadata
Placement of creation metadata
  • Same options as for all metadata
  • Embedded 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 i
UBC Creation Metadata I
  • The notion of a complete record
    • Medium
    • Content
    • Form
    • Persons (author, writer, addressee, creator)
    • Acts
    • Archival bond
    • Transmission (intent, capability, success)
ubc creation metadata ii
UBC Creation Metadata II
  • “Elements 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 subject
    • Disposition/purpose (the intention of the record)
ubc creation metadata iii
UBC Creation Metadata III
  • The notion of reliable record; must in addition to completeness have:
  • “Document profile” as container for the object
    • Date available (created or received)
    • Time available (created or received)
    • [Date and time of further transmission]
    • Author
    • Addressee
    • Subject [classification code, registry number]
dod 5015 2 recordkeeping standard assumptions
DoD 5015.2 Recordkeeping Standard: Assumptions
  • Note that 5015.2 assumes an entire detailed recordkeeping system that fully accounts for all records at the series, folder, and individual level
  • The “file plan” defines the recordkeeping system; the “schedule” is applied to entities defined in the file plan

DoD 5015.2 email metadata mapping
  • Sender (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 reliability
Date/time and persons: vital to records’ reliability
  • Without date/time, not possible to manage records by date: cutoffs, retention, destruction
  • Without persons (author, recipient, creator), nobody would care
  • Without hierarchical set of data categories, no structure
  • Note dependence on systems in which records creation are embedded
what about non text objects
What about non-text objects?
  • Creation metadata for non-text objects covers much the same ground:
    • Information about occasion of creation, including technical information (version of coftware, settings)
    • Information about creator, intention, receiver
    • Information about the object itself
connecting metadata to a non text object
Connecting metadata to a non-text object
  • Object is kept in specifically-defined file structure
  • File name/ID is crucial to the connection
  • XLink is used to connect the two using a series of XML attributes:
