A Manakin Case Study: Visualizing geospatial metadata & complex items

  1. 1. A Manakin Case Study Visualizing geospatial metadata & complex items Adam Mikeal, Cody Green, Alexey Maslov, Scott Phillips, Kathy Weimer and John Leggett
  2. 2. 1. The Setup 2. The Collection Overview 3. The Problem 4. The Solution 5. The Result
  3. 3. The Setup 1
  4. 4. Repositories increasingly contain complex items Metadata needs are Background moving beyond basic Dublin Core Traditional approaches fall short
  5. 5. The Collection 2
  6. 6. 227 folios of maps, text and photographs Geologic Atlas Published by the USGS of the between 1894 and 1945 United States Focuses on economic geology and geography
  7. 7. Value largely historic in nature, but some instances still represent the most recent geologic survey of that coverage area Textual content contains information on geologic features and economic geology of the area
  8. 8. Each folio consists of between 10 and 40 pages Archival images are 300 Digitized folios dpi TIFF, ~100 MB each Only complete digitized version of this series in existence
  9. 9. 1 collection, 227 items DSpace Each item had multiple bitstreams; one for each scanned page collection Extra bitstream added; PDF for screen-viewing
  10. 10. Geospatial metadata exists in multiple formats Needed Qualified Dublin Core Geospatial Used DCMI metadata recommendations for values: coverage.point: 41:30:00N87:45:00W coverage.box: northlimit=41.75; westlimit=-88; southlimit=41.5; eastlimit=-87.75
  11. 11. The Problem 3
  12. 12. DSpace interface optimized for items with fewer bitstreams Browsing Uninformative lists + large files = very cumbersome browsing
  13. 13. No way to easily place the folios in their geographic context Coverage No searching across coverage area Search results not in context
  14. 14. Bottom line Great collection, poor user interface Failed to leverage unique properties of the collection
  15. 15. The Solution 4
  16. 16. Manakin Of course :-)
  17. 17. List model caused frustrating user experience Item View Root problem: complex items Exploration causes loss of context
  18. 18. Gallery-style thumbnails provide visual overview Lightbox-style previews provides detail in context Full-size JPEG allows for alternate download option
  19. 19. Gallery-style thumbnails provide visual overview Lightbox-style previews provides detail in context Full-size JPEG allows for alternate download option
  20. 20. Gallery-style thumbnails provide visual overview Lightbox-style previews provides detail in context Full-size JPEG allows for alternate download option
  21. 21. Gallery-style thumbnails provide visual overview Lightbox-style previews provides detail in context Full-size JPEG allows for alternate download option
  22. 22. Manakin made this easy; merely override the item view template (XSL) Manakin’s role Method easily extends to more complex item Item view structures Built-in METS would allow for correlation of images
  23. 23. Map-based interface obvious choice for context Yahoo! Maps chosen for Collection view ease of API and aesthethic qualities Geographic coordinates were available for every item
  24. 24. Map places every item into a geographic context Allows user to quickly determine coverage area Provides a visual understanding of the geographic context
  25. 25. Map places every item into a geographic context Allows user to quickly determine coverage area Provides a visual understanding of the geographic context
  26. 26. Manakin made this easy; merely override the collection view template Manakin’s role Example of a customized collection within an Collection view existing repository XSL used to write the JavaScript that renders the map
  27. 27. Search results needed to be placed in geographic context, too Search view Searching capabilities should be customized to the collection’s needs
  28. 28. Search results are plotted on the map for visual placement Search results are listed underneath for more detail Search interface customized for collection’s particular needs
  29. 29. Search results are plotted on the map for visual placement Search results are listed underneath for more detail Search interface customized for collection’s particular needs
  30. 30. Manakin made this easy; merely override the search view template Manakin’s role Customized results required overriding the Search view search results template XSL used to renders map, reading Lat/Lon coordinates from DRI
  31. 31. The Result 5
  32. 32. Better user experience Bottom line Improved access Utilizes the unique properties of the collection
  33. 33. Web 2.0 It’s a mash-up!
