Drupal with CONTENTdm Digital Collections, Drupal Camp Vancouver 2012


Published on

CONTENTdm is a digital collections management application that provides several important administration features of value when undertaking a digitization project. Many institutions already use Drupal to power their web presence. CONTENTdm's native interface makes creating a single integrated website difficult. The CONTENTdm Integration Modules project was created by Mark Jordan of Simon Fraser University Library to solve this issue by providing a series of Drupal modules that help create a single integrated website - allowing the searching of digital collections hosted in a CONTENTdm server from within a Drupal website.

By the end of this talk, you will have a better understanding of:

*Why you would want to use CONTENTdm rather than simply Drupal for digital collections management;

*How the CONTENTdm Integration Modules work under the hood;

*How to install and setup these modules with Drupal to help present an integrated website.

This talk will be of particular interest to those who develop Drupal websites for use in libraries, archives, or museums, but also to Drupal developers and administrators in general.

  1. 1. Drupal with CONTENTdm Digital CollectionsMarcus Barnes, Simon Fraser University, June 2, 2012
  2. 2. • Overview and Introduction: Drupal in Libraries and CONTENTdm• CONTENTdm Integration Modules• Tutorial Demo: Getting started with the CONTENTdm Integration Modules• Closing Remarks with Q/A.Outline 2
  3. 3. • 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 listBottom Line:Drupal offers the flexibility and control necessary for a librarywebsite while leveraging the power of an active open sourcecommunity.Drupal in Libraries 3
  4. 4. • 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.CONTENTdm 4
  5. 5. CONTENTdm Windows Client:Editing an Uploaded Item 5

  7. 7. • “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 customizationOverview of the CONTENTdm modules 7
  8. 8. • 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 browsingOut of the box 8

  10. 10. • 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 CONTENTdmCONTENTdm Web Services API 10
  11. 11. • 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 JSONCONTENTdm API details 11
  12. 12. • 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/jsonCONTENTdm API REST URLs 12
  13. 13. • Sites that run the modules: – Multicultural Canada (SFU) – Denver Public Library – Komagata Maru Journey (SFU) – Chinese Canadian Stories (UBC)CONTENTdm Integration Modules 13
  14. 14. 1. dmQuery – Searches CONTENTdm and returns a result list2. dmGetItemInfo – Returns metadata, filename, and full text for the designated item3. dmGetCompoundObjectInfo – If the item is compound, returns a list of all its children and its hierarchical structureCONTENTdm REST API:Typical Use Pattern 14
  15. 15. • 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 CONTENTdmCONTENTdm API: Applications 15
