• Core Services

  • Media Streamer:
    • Provides streaming capabilities for video and audio files.
  • Duplicate on Upload:
    • Provides a simple mechanism for synchronizing your content between two storage providers. A running Duplicate on Upload service will listen for updates on ingest which occur in one store and duplicate those activities in another store.
  • Duplicate on Demand:
    • Provides a simple way to duplicate content (and its associated metadata) from a space in the primary storage provider to a space in another provider.
  • Image Server:
    • Deploys an instance of the Adore Djatoka web application which provides serving and viewing of JPEG2000 images. Note that in order to view images using the Image Server, the images must be in an OPEN space.
  • Image Transformer:
    • Provides a simple way to convert image files from one format to another.
  • Bulk Image Transformer:
    • Handles the conversion of large numbers of images files from one format into other.
  • Bit Integrity Checker:
    • Provides the ability to verify that the content held within DuraCloud has maintained its bit integrity. There are five modes of operation:
      • (1) All-in-one generation of system MD5s for items in provided listing and verification;
      • (2) All-in-one generation of system MD5s over entire space(s) and verification to provided listing;
      • (3) Generation of system MD5 listing for items in provided listing;
      • (4) Generation of system MD5 listing over entire space, and;
      • (5) Comparison of two provided MD5 listings.
  • Bulk Bit Integrity Checker:
    • Provides a simple way to determine checksums (MD5s) for all content items in any particular space by leveraging an Amazon Hadoop cluster. This service is designed for large datasets (+10GB).

• Utility Services

  • System WebApp Utility:
    • Coordinates the installation/deinstallation and startup/shutdown of Apache Tomcat instances that are created to run web application services and are deployed outside of the hosting OSGi container.
    • Required to run Image Server.
  • System Transformer Utility:
    • Deploys the ImageMagick application which allows other services to take advantage of its features.
    • Required to run Image Transformer.

  Tip
  title Browser Support Note
  DuraCloud currently supports all of the major web browsers: Chrome, Safari, Firefox, and Microsoft Edge. As of version 3.7.0, DuraCloud no longer supports Microsoft Internet Explorer. This change is in response to Microsoft's recent end of support announcement for Internet Explorer. This shift allows development effort to be focused on delivering the highest quality user experience for the vast majority of our users. If you are still using Internet Explorer, we recommend you consider moving to one of the supported browsers mentioned above.

Core Services

• Media Streaming:
• • Provides streaming capabilities for video and audio files.
• Bit Integrity Checking:
• • Verifies that content stored in DuraCloud maintains bit-level integrity over time by calculating a checksum value upon content storage and the at frequent intervals to ensure no changes have occurred
• Duplication:
  • Keeps content in multiple storage providers consistent.

Tools

• Sync Tool:
  
  • Provides a utility with both graphical and command line utility interfaces for keeping DuraCloud content synchronized with the local file system.
• Retrieval Tool:
  
  • Provides a command line utility for transferring content stored in DuraCloud to the local file system.Chunker Tool: Provides a command line utility for transferring single files to DuraCloud.
