## Member Function Documentation

OAIClient::GetFormats | ( |  | ) |

Retrieve list of available metadata formats from repository server.

Returns:
  array containing list of available metadata formats

Definition at line 160 of file OAIClient.php.

OAIClient::GetIdentification | ( |  | ) |

Retrieve identification information from repository server.

Information is returned as associative array with the following indexes: "Name", "Email", "URL".

Returns:
  array containing identification info

Definition at line 130 of file OAIClient.php.

OAIClient::GetRecord | ( | $ | Id | ) |

Get a single record from a repositry server.

NOTE: due to the history and politics involved, it is generally preferable to use GetRecords() to pull a full dump from the remote provider and then filter that to get a subset. The thinking here is that pulling in batches will result in fewer queries to the remote, which is kinder to their hardware. Pull single records with caution, when only a small number of them are required.

Parameters:

  | Id | The unique identifier of the desired record

Returns:
  array of records (zero or one entries) returned
