Drupal in Libraries
• Used by many libraries • Rich API• Thousands of ‘contrib’ modules• Ease of integrating with other systems• Thriving Drupal library community
• http://drupalib.interoperating.info• http://groups.drupal.org/libraries• drupal4lib email list

Bottom Line: Drupal offers the flexibility and control necessary for a library website while leveraging the power of an active open source community.

CONTENTdm
• CONTENTdm: “digital collection management software that allows for the upload, description, management and access of digital collections.”1 (Product offering of the Online Computer Library Center, Inc. (OCLC) [a non-profit membership cooperative.]
• Complex issues involved with digital collections – CONTENTdm is a vertical application that helps better manage these issues into the workflow.
• Windows client especially useful for enforcing business rules and quality control during the digitization and uploading stages of a project.

Overview of the CONTENTdm modules
• “A set of modules that allows users to search, browse and view CONTENTdm 6.x collections from within a Drupal website”
• Hosted at http://drupal.org/project/contentdm• Design principles
– Modularity– Extensibility– Ease of customization

Out of the box
• Basic search module• Viewers for image, PDF, media, compound
items, URL, and plain text items• Hierarchical document browser• Custom queries module, for prebuilt search
results• A 'scopes' module, which defines subsets of
CONTENTdm collections for searching and browsing

CONTENTdm Web Services API
• The Web Services API makes the CONTENTdm PHP API available through a REST interface
• SFU developed this API during the Multicultural Canada project, in partnership with Athabasca University
• Rationale: We needed to run the MCC website on a different web server than CONTENTdm was running on.– The PHP API was only available if you ran your
application (e.g., Drupal) on the same web server as CONTENTdm

CONTENTdm API details
• Released by OCLC as part of CONTENTdm 6.x
• REST calls mirror CONTENTdm 5.x PHP API functions– E.g., dmGetCollectionList, dmQuery,
dmGetItemInfo
• Response from CONTENTdm is returned in either XML or JSON

CONTENTdm API REST URLs
• Generic form– http://CdmServer.com:port/dmwebsetrvices/
index.php?q=function/param1/param2/format/help/log
• Specific example– http://content.lib.sfu.ca:81/dmwebservices/
index.php?q=dmQuery/all/subjec^canada^all^and/title!subjec/title/50/1/0/0/0/0/json

– Multicultural Canada (SFU)
– Denver Public Library
– Komagata Maru Journey (SFU)
– Chinese Canadian Stories (UBC)
CONTENTdm Integration Modules
![Page 14: Marcus Barnes, Simon Fraser University, June 2, 2012 Drupal with CONTENTdm Digital Collections.](https://reader036.fdocuments.net/reader036/viewer/2022070400/56649eff5503460f94c142ee/html5/thumbnails/14.jpg)
CONTENTdm REST API:Typical Use Pattern
1. dmQuery– Searches CONTENTdm and returns a result list
2. dmGetItemInfo– Returns metadata, filename, and full text for the
designated item
3. dmGetCompoundObjectInfo– If the item is compound, returns a list of all its
children and its hierarchical structure

CONTENTdm API: Applications
• CONTENTdm Integration modules for Drupal– http://drupal.org/project/contentdm
• Canadiana.org Metadata Exporter
• LOCKSS-friendly front end to CONTENTdm
• SFU Multisearch also uses the API to query CONTENTdm

Assumptions:
•You know how to install an instance of Drupal 6.
•You have access to a CONTENTdm Server.
![Page 20: Marcus Barnes, Simon Fraser University, June 2, 2012 Drupal with CONTENTdm Digital Collections.](https://reader036.fdocuments.net/reader036/viewer/2022070400/56649eff5503460f94c142ee/html5/thumbnails/20.jpg)
Future plans
• Migration to Drupal 7• Better synchronizing of updated / reloaded
items in CONTENTdm• Integration of more media viewers
– HTML5 media– PDFObject
• Integrate new features of the CONTENTdm APIs as they become available– Catcher
