Lecture 4: Metadata

  1. 1. Metadata in Concept and Practice K R I S T I PA L M E R K L PA L M E R @ I U P U I . E D U F E B RUA RY 4 , 2 0 1 3 http://www.niso.org/standards/resources/UnderstandingMetadata.pdf
  2. 2. what is metadata? you tell me. . . information about information “structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource.”* “value added information that is created to arrange, describe, track and otherwise enhance access to information objects.”** cataloging is creating metadata. . .how is it different? *Understanding Metadata by NISO Press (2004), p. 1. ** Gillaland-Swetland, A. J. (2000). Introduction to Metadata: Setting the Stage. www.getty.edu/research/institute/standards/intrometadata/, p. 2.
  3. 3. why is metadata important? find what we are looking for find what we didn’t know we were looking for assembling items that have something in common finding out how items are different accessing an item preserving an item sharing an item/information easily tells us how an item is used indicates authenticity inform of legal issues
  4. 4. STANDARDIZE If metadata is to be effective on a broader scale we must. . .  use standardize forms of metadata,  use a standard that is specific to our purpose for creating the information,  use a standard that considers the audience or information users.
  5. 5. examples of metadata amazon ebay art.com allrecipes google maps mibor
  6. 6. 3 main types/forms of metadata1. descriptive metadata describes a resource for purposes of discovery and identification it’s the words you can search by2. structural metadata indicates how objects are put together, for ex. the order of pages in a chapter it’s technical, behind the scenes metadata
  7. 7. 3 main types/forms of metadata3. administrative metadata provides information to help manage a resource it is also often, behind the scenes metadata rights management metadata copyright, usage rights information preservation metadata archiving and preservation information

  9. 9. each metadata standard has. . . element set the list of fields (and their definition) in a metadata standard for example, Title is one item in a Dublin Core element set content rules (optional) the rules for constructing the elements that will be a part of this field for example, Capitalize first word in field and end with a period OR the Title of the item can only be taken from words written on the first page of the document are rules for the Title element syntax rules (optional) the rules for tagging or encoding the metadata scheme for example, Dublin Core schemes use XML tagging
  10. 10. Example metadata standards Dublin Core all encompassing (descriptive) TEI literature MARC libraries (traditional catalog data) METS libraries (structuring descriptive data) ONIX publishers CSDGM data sets, geospatial info. (for GIS) GEM educational materials VRA Core art, visual works EAD archives, special collections, finding aids RDF web data, characterized by triplicates, used in linked data, allows integration of various standards
  11. 11. example public and xml records public record https://scholarworks.iupui.edu/handle/1805/640 METS XML with DC https://scholarworks.iupui.edu/metadata/handle/1805/640/mets.xml
  12. 12. standards: controlled vocabulary LCSH general, can combine terms to make more complex headings TGM I and II graphic materials, photos, prints AAT architecture, paintings, sculpture, art in general TGN place, geographic names GEM education materials MeSH medical termsExtensive list of vocabularies at: Taxonomy Warehouse
  13. 13. metadata crosswalksMetadata crosswalks translate one field in a particularorganizing scheme or database into another field ofanother organizing scheme or database. http://www.getty.edu/research/publications/electronic_publicatio ns/intrometadata/crosswalks.html
  14. 14. standards: descriptive metadata schemes schemes or element sets  Dublin Core all encompassing  TEI literature  MARC libraries  ONIX publishers  CSDGM data sets, geospatial info. (for GIS)  GEM educational materials  VRA Core art, visual works  EAD archives, special collections, finding aids
  15. 15. let’s examine a record at depth
  16. 16. let’s practice: Indianapolis Sanborn Maps Decide:  Who is your audience?  How will this audience access, search, interact?  What elements do you want to describe?  What DC tags will you connect to each described element?  What public field name will you give each DC tag?  Will you use any controlled vocabularies if so for what described element?
  17. 17. what did you come up with? What does your metadata schema and record look like? Example Sanborn collections  Indianapolis http://indiamond6.ulib.iupui.edu/cdm/ref/collection/SanbornJP2/id/473  Milwaukee http://collections.lib.uwm.edu/cdm/landingpage/collection/san  Pennsylvania http://collection1.libraries.psu.edu/cdm/ref/collection/maps1/id/2198  Georgia http://dlg.galileo.usg.edu/sanb/id:dublin_ga-1913-s-4  Nevada http://www.delamare.unr.edu/maps/digitalcollections/nvmaps/sanborns/
  18. 18. Thinking about digital history and going beyond making paper digital… What datasets could you imagine connecting to these maps? What other ways of map interaction can you imagine?
  19. 19. questions?
