1. E-Gov E-Records Management Project

• NARA
• Has the lead on the E-Gov E-Records Management
  Project.
• Identified two study areas
• Accepting new electronic record formats such as
  scanned images, PDF, etc.
• Develop archival and records management metadata
  to facilitate transfer of these records.
• EPA
• Interested in leading/co-leading the second study
  area as part of ERDMS work.

1. E-Gov E-Records Management Project

• Two milestones
• September 30, 2002
• Define standardized organizational strategic
  approaches to phased implementation of electronic
  recordkeeping in a federal agency.
• December 31, 2002
• Develop metadata record needed to use XML as the
  common language for transferring permanent
  e-records to NARA.
• Goal
• Propose and pilot test common metadata
  stylesheets for NARA and federal agencies use to
  transfer electronic records.

1. E-Gov E-Records Management Project

• Problem with Acrobat PDF files
• NARA will not accept because not XML.
• NARA is in discussions with Adobe, Inc. about
  this problem.
• Adobe, Inc. position on XML
• XML and PDF compliment one another.
• My comments
• Actually one can produce a PDF from XML by using
  an XML Formatting Objects Stylesheet (XSL-FO).
• An Acrobat Plug-in provides PDF-to-XML
  conversion
• My comments
• This only works if the PDF is of the third type
  (tagged) and it still needs additional work to
  make a useful XML document.

2. Adobe 5.0 Document Metadata

• Viewing Document Metadata In Acrobat 5.0, Adobe
  PDF files contain Document Metadata in XML
  format. This Document Metadata contains (but is
  not limited to) information that is also in the
  Document Properties. Any changes made in the
  Acrobat Document Properties dialog box are
  reflected in the Document Metadata. Because
  Document Metadata is in XML format, it can be
  extended and modified using third-party products.
  You can copy and paste the Document Metadata XML
  source code.
• To view the Document Metadata
• 1 Choose File, Document Properties, Document
  Metadata.
• 2 The Document Metadata dialog box displays all
  the metadata embedded in the document. (Metadata
  is displayed by schemathat is, in predefined
  groups of related information.) The information
  associated with each schema is visible by
  default it can be hidden by clicking the
  triangle next to the schema name. If a schema
  doesnt have a recognized name, it is listed as
  Unknown.The XML name space is contained in
  parentheses after the schema name.
• 3 To view the XML code, click View Source.You can
  cut, copy, and paste XML code from the Metadata
  Source View dialog box. Click OK to return to the
  Document Metadata dialog box.
• 4 Click OK to close the Document Metadata dialog
  box, and click Cancel to close the dialog box
  without making any changes.
• See next slides.

3. Repurposing Adobe PDF Documents

• See Acrobat 5.0 Help
• Repurposing Adobe PDF Documents (pages 82-90) and
  Working with PDF (pages 103-107)
• Creating tagged Adobe PDF documents (need to do
  for accessibility anyway).
• Saving Adobe PDF documents to other formats (RTF
  and XML). See next slides.
• But still need XML authoring tools and expertise
• I have done this for lots of EPA documents in my
  XML Web Services training.
