• Separated storage layer
  • Allow for resources to be stored in files or different database systems
• Isolate storage details from pipeline functionality
  • Change providers without changing pipeline configuration
• Allow extremely large dictionary resources to be stored and used centrally
  • For example, in a REDIS or similar distributed key-value system
• Allow for Dev, Staging, and Production publishing
• Allow for business user editors to edit dictionaries and publish updates
• Allow for publishing of dynamic updates linguistic resources

Resource Providers

A resource provider provides access to a specific set of resources from a particular storage technology. For example, a file system directory of resource files or a collection of tables.

Available Resource Provider Implementations

Locating the Resource Provider Class

The "type" parameter is used in resource configuration to locate the resource provider class. for example:

...

"type":"FileSystem"

or

...

"type":"com.accenture.saga.resourcemgr.filesystem.FileSystemProvider"

The type parameter is used to locate the class using the following steps:

1. If the type parameter has periods in it

   1. Try and look for the class as specified

      1. For example:  com.accenture.saga.resourcemgr.filesystem.FileSystemProvider

2. Otherwise:

   1. Try and find the class in the "com.accenture.saga.resourcemgr.filesystem" package

      1. For example:  "FileSystemProvider" → "com.accenture.saga.resourcemgr.filesystem.FileSystemProvider"

   2. Try and find the class with a "Provider" suffix in the "com.accenture.saga.resourcemgr.filesystem" package

      1. For example:  "FileSystem" → "com.accenture.saga.resourcemgr.filesystem.FileSystemProvider"

Types of Resources

Currently, there are three types of resources defined:

...

The following is a sample resource providers configuration:

{
  "providers": [
    {
      "name":"pipeline-provider",
      "type":"FileSystem",
      "baseDir":"config"
    },
    {
      "name":"dict-provider",
      "type":"MongoDB",
      "uri":"mongodb://localhost:12345",
      "database":"dictionaries"
    }
  ]
}
