What "Manifesting" means

In the Alexa Web Search Platform documentation, you will run across the word manifesting. That's right, it's a gerund!

Here's an example of how the AWSP docs use it:

For instanace, the Platform's Default framework is responsible for manifesting a collection and distributing a user's application across multiple compute nodes to efficiently process the collection.

The AWSP docs use manifesting as a fancy computer science way of saying: collecting, grouping and assigning to a particular bucket. More simply, they mean requesting that a specific bunch of documents be grouped and named into a collection.
