  1. Blackboard Building Blocks Introduction to Building Blocks Bob Alcorn, Director, Platform Architecture Tuesday, September 2, 2014

  2. Topics • Goals of Building Blocks • What are Building Blocks • Types of Building Blocks • Building Blocks Program Components • Developers Community • Building Blocks Roadmap

  3. Goals of Building Blocks For Students and Instructors Access to a wide range of discipline specific, pedagogically specific, and more engaging content and applications.

  4. Goals of Building Blocks For System Administrators Creation of new breeds of applications to aid in the deployment management and operation of the Blackboard Platforms. Integration of other tools, applications, and services under a common platform.

  5. Goals of Building Blocks For Developers Create an extensible platform which can be used to create exciting new applications, integrate existing tools, and extend the core modules on top of a common, easy to learn, platform.

  6. Goals of Building Blocks For Partners Create a marketplace for 3rd party application developers and consultants for their products and services.

  7. Goals of Building Blocks For the CIO, CFO Enhance the ROI for Blackboard and other applications which can be integrated together to increase utilization.

  8. Goals of Building Blocks For Blackboard Extend the value proposition for our clients far beyond what we as a single company can provide.

  9. Technical Goals – High Level • Iterative functionality • Start with lightweight objects • Managed extensibility • System extensions and deployment model • Well defined entry points • Non-binding entry points • Simple persistence • Database abstraction • XML and Database • Originally targeted for import/export

  10. What are Blackboard Building Blocks? Blackboard Building Blocks (B2) is the underlying architecture that enables the Blackboard platform to easily integrate educational web-based tools and content that meet institution-specific, discipline- specific or accessibility needs.

  11. Blackboard Building Blocks • It is NOT just a set of Application Programming Interfaces (APIs) • It is a framework for extending the Blackboard Platforms, integrating new components, and interoperating with other applications. • It is a robust program for facilitating the development of enhancements to the Blackboard platforms.

  12. Building Blocks Across Products

  13. Content Library Systems Security Communication Content Mgt Collaboration Content Authoring Assessment Back Office Systems Homegrown Applications “Operating Environment” Blackboard Building Blocks

  14. Building Blocks Technology • Java Platform • JDK 1.3.1 and higher • Web application • Servlet 2.3 • JSP 1.2 • Security • Blackboard APIs • Data APIs • Service APIs • Tag Libraries (JSP/Servlet)

  15. Building Blocks Technology Web Server (IIS, Apache) Tomcat Database (SQL Server,Oracle) Web app Perl (ActiveState,mod_perl)

  16. Anatomy of a Building Block Package (.war/.zip file) web.xml (Servlets) Platform Descriptor Content Type, Tools, etc. Blackboard Manifest Web Resources Servlets, JSP (Java) Libraries .class, .jar files (Java)

  17. Security Session Context Plug-ins Log Config Persistence I18N VXI Building Blocks Architecture Business Layer (JSP, Servlet, Struts) View Layer (JSP, Servlet, Tag Library) Data Objects Core Services

  18. Types of Building Blocks • Extend Existing Blackboard Functionality • Add New Functionality into Blackboard • Integrate 3rd party applications with Blackboard • Integrate Blackboard with “Back-office” SIS and Authentication Systems • Create and Consume XML-Based Web Services • Provide and Render portal modules, portlets, and RSS Channels • … and MORE!

  19. Content Engine Text Images Multimedia Types of Building Blocks • Building Blocks which extend the existing functionality within Blackboard • Example: Adding a new content type and handler to the content engine such as a WYSIWYG Editor Application Application Application Application Application Application Application Blackboard Platform Building Blocks Manager WYSIWYG SQL JAVA WYSIWYG

  20. Types of Building Blocks

  21. Dictionary/Thesaurus Types of Building Blocks, contd. • Building Blocks which add new functionality to Blackboard and take advantage of the Blackboard platforms “machinery” to run. • Example: Adding a new tool such as the dictionary / thesaurus tool to Blackboard. Application Application Application Application Application Application Blackboard Platform Building Blocks Manager SQL JAVA Dict / Thes

  22. Types of Building Blocks, contd.

  23. SQL C++ 3rd Party Assessment Engine Types of Building Blocks, contd. • Building Blocks which integrate a third party application with Blackboard • Example: Adding a new assessment engine to Blackboard Integration Agent Application Application Application Application Application Gradebook Bb Assessment Blackboard Platform Building Blocks Manager SQL JAVA Integration Agent

  24. Types of Building Blocks, contd. LDAP SIS • Integration Agents which integrates Blackboard with Back-office ERP systems such SIS system as well as authentication systems such as LDAP and Kerberos. Authentication Agent ERP Integration Agent Application Application Application Application Application Application Application Blackboard Platform Building Blocks Manager SQL JAVA

  25. Application Types of Building Blocks, contd. Web Service • Integration agents or Building Blocks which interoperate with XML based Web Services. Application Application Application Application Application Application Application Blackboard Platform Building Blocks Manager SQL JAVA

  26. Types of Building Blocks, contd. • Building Blocks which add new modules to the portal. • Example: adding a portal module which allows students and faculty to preview the menu at the dining halls. Portal Module Portal Module Portal Module Portal Module Portal Module Portal Module New Portal Module Blackboard Platform Building Blocks Manager SQL JAVA New Module

  27. Types of Building Blocks • Meta-data driven • Different “types” really just means different “entry points” • Defined in bb-manifest.xml • Types are not specifically enforced • A “content handler” could in fact launch a collaboration component

  28. Building Blocks Program Components • Building Blocks Web Sites • http://www.blackboard.com • Extend Blackboard “Tab” • Learn about Building Blocks • Building Blocks Catalog • Featured Building Blocks • Community Links • Developers “Tab” • Building Blocks Software Developers Kit (SDK) • Documentation • Sample Code

  29. Building Blocks Program Components • Blackboard Developer Network (BbDN) • Developer Tab • Bb Developer Licenses • Communities, Knowledge Base, Code Snippets, White Papers, Beta Software • “Blackboard Enabled” Logo Program
