Understanding the rules

• You have to work within CONTENTdms application
  framework, i.e.
• CONTENTdms indexes can only be easily accessed
  via an .exe in the CGI-BIN so the OAI is your
  friend
• That nearly all data is stored in plain text
  files and are accessible via http/file level
  access
• Examples
• Project Configuration Files http//digitalcollect
  ions.library.oregonstate.edu/archives/index/etc/co
  nfig.txt
• Vocab. Files http//digitalcollections.library.or
  egonstate.edu/archives/index/text_search/voc.creat
  o
• In general, all data not within a results grid
  can be easily customized using javascript

Retrieving Data OAI the CONTENTdm API

• Two primary methods for accessing collection data
  dynamically within CONTENTdm
• API
• Example queryget.exe
• Usage Example http//digitalcollections.library.o
  regonstate.edu/cgi-bin/queryget.exe?CISOROOT0/arc
  hivesCISOROOT1/fakecollectionCISOOPallCISOMAX

Retrieving Data OAI the CONTENTdm API

• Two primary methods for accessing collection data
  dynamically within CONTENTdm
• OAI
• Retrieves all Dublin Core tagged Fields
• Retrieves data as simple Dublin Core
• Example
• http//digitalcollections.library.oregonstate.edu/
  cgi-bin/oai.exe?verbListRecordsmetadataPrefixoa
  i_dcsetarchives

Examples E-Commerce Extension

• E-commerce extension
• What it does
• Allows institutions to implement a shopping cart
  feature with CONTENTdm
• Provides patrons with a printout receipt of their
  orders
• Provides staff with an html encoded email with
  links into the CONTENTdm collection to eliminate
  confusion regarding staff requests
• Provides a method to potentially allow online
  billing of documents
• Method will vary from institution to institution
  based on their business offices rules and
  practices

Examples E-Commerce Extension

• E-commerce extension
• How it works
• Modifications to the global.js script to
• Insert shopping cart buttons in the item
  results windows
• Add Cookie parsing and Packing functions
• The script uses the same cookie as the My
  Favorites functionality, allowing the Shopping
  Cart to import data from the My Favorites list.
• Creation of two php scripts
• mycart.php (handles the data retrieval submission
  form generation)
• request.php (generates emails this request
  also provides the fork point for online payment
  if available)

Examples E-Commerce Extension

• E-Commerce extension
• Data flow
• Patron clicks on shopping cart link to pack
  CISOPTR into the cookie.
• Patron clicks on order prints link to generate
  the request form.
• Request form (mycart.php) generates an OAI
  request for each item and extracts the necessary
  data required to generate the print/email
  request.
• Patron enters data submits data receipt is
  generated and user is given one last opportunity
  to verify data.
• Submits data Email is sent to staff which fill
  the request.

Examples RSS Generator

• RSS Feed Generator
• Probably the most widely used CONTENTdm extension
  in our library.
• Used by
• Librarians to track individual collection or
  topical growth within collections.
• Managers (like myself) as a review tool to keep
  track of items as they change and check resulting
  metadata.

10
Examples RSS Generator

• RSS Feed Generator
• How it works
• Uses OAI for data retrieval
• OAI is called using date limiters that can be
  specified by the user
• SAXON for XSLT parsing
• This allows the OAI to be pre-processed to
  Qualified Dublin Core and then processed against
  a users processing instructions. Using XSLT, the
  user can
• Query items with specific keywords
• Query items with specific creators/titles
• Query items with a combination of criteria XSLT
  step simply allows script to produce queries
  using a level of granularity that isnt available
  in OAI.
• RSS Feed reader to display results

• Example
• Within Bloglines

Things Id like to see or am working on

• An Open-Source Acquisitions client built in Java
  (so it can be run on Linux and customized for
  specific workflows
• Open Source Multi-Site server solution
• True OBDC driver to access CONTENTdm database
  natively within scripts
• More folks developing and sharing their
  development.

Going Further Embedding Rights Management

• Rights management example how it works
• Generate a wrapper .exe for the CONTENTdm display
  exe.
• Embed rights management metadata into individual
  items
• Have the wrapper pre-process requests on the
  server, pulling data from CONTENTdm using the
  OAI.
