* Implements Earthgrid REST API to Metacat <br/><br/>
|
|
| 56 |
* Base class for handling D1 REST calls in Metacat

* <h3> EarthGrid Query Service</h3> |
|
| 116 |
* <ul><li> |
|
| 117 |
* <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 |
* in the query string. <br/><br/> |
|
| 121 |
* |
|
| 122 |
* <b>REST URL:</b> <code>GET, [context-root]/object/[doc-id]?sessionid=[sessionid] </code><br/> |
|

* <h3>Query & Authenticated Query:</h3> |
|
| 128 |
* Metacat's equivalent is squery action but this function |
|
| 129 |
* receives a Earthgrid query document and returns Earthgrid resultset document by transforming those documents |
|
| 130 |
* to Metacat's equivalents by the means of Metacat Implementation in Earthgrid library. For authenticated Query service |
|
| 131 |
* a session id must be provided in the query string. See Earthgrid (a.k.a. Ecogrid) project for XSD files of |
|
| 132 |
* query and resultset documents<br/><br/> |
|
| 133 |
* |
|
| 134 |
* <b>REST URL:</b> <code>POST, [context-root]/object?sessionid=[sessionid]</code> <br/> |
|
| 135 |
* <b>POST Data:</b> Earthgrid query document , Content-type: <code>text/xml</code><br/> |

* <h3>Login: </h3> |
|

* Receives username and password parameters in POST data and |

| 148 |
* returns SessionId (in XML format) or failure message and uses MetacatHandler's handleLoginAction function<br/><br/> |
|
| 149 |
* |
