Within the Islandora context there have been a number of ways paged content has been handled. One of the simplest approaches to paged content is to store it as a PDF document. This continues to be a viable option in Islandora and is supported by a number of solution packs including the PDF Solution Pack. A more sophisticated and preservation friendly approach to paged content is to treat pages as individual digital objects that are related to a parent object. The Book Solution Pack uses this model and it can be repurposed to satisfy many paged content models including journal content by modifying the metadata required. For instance, the Newspaper Solution Pack shares much of the same code as the Book Solution pack, but metadata requirements and the viewer are different.

2. Outline
• Content Models
• Role of Metadata
• Preparing Content for Ingest
• Derivative Creation
• Display

3. Content Models
• Book/Monographs/Journals/Periodicals/
Newspapers
• Formats: tiff, jpeg, jp2000, pdf(pdf/a)
o PDF is stored as single continuous object
o Books and Periodicals stored atomistically

4. RDF Statements
Book Object
Page Objects

5. Book Object: Datastreams
RELS-EXT RDF statements connecting book to collection
MODS MODS metadata
DC Dublin Core metadata
TN Display Thumbnail
PDF (Optional) Optional PDF can be generated and stored at the
book level of all pages

6. Page Object: Datastreams
RELS-EXT RDF statements connecting pages to book and
declaring the order of pages
MODS MODS metadata
DC Dublin Core Metadata
TN Display Thumbnail
OBJ TIFF representing page
JP2 JPEG 2000
JPG Display JPEG (for reader)
OCR Text (generated or uploaded)
HOCR Coordinate data for generated text only
PDF (Optional) PDF for single page can be generated and stored
with the object

7. Management functions
for book pages
• Reordering,
deletion,
replacement (of
object or
derivatives)

8. Approaches to Metadata
• Default is MODS and DC
• Ability to add different metadata at Book &
Page level
• Ability to add encoded text stream (TEI and
HOCR)
o Syncing issues
o TEI schema
• Next: How is content created and managed?
