|
* <h3>Get & Authenticated Get:</h3>
|
| 118 |
|
* is equal to Metacat's read action and returns a data file having
|
| 119 |
|
* the specified <doc-id> in the resource path. For authenticated Get service, a session id must be provided
|
| 120 |

|
* to Metacat's equivalents by the means of Metacat Implementation in Earthgrid library. For authenticated Query service
|
| 131 |
|
