Files Data Resource Configuration Document

Data resource configuration involves specifying information about a data resource including the root directory and any metadata. Configuration is done using a data resource configuration document.

Data resource configuration documents are written by OGSA-DAI service deployers.

A data resource configuration document includes information on the following:

• The root directory that clients can access.

For the remainder of this page we give an overview of the general format of the data resource configuration document used by a files data resource accessor.
