|
*
|
||||||
|
* - $identifyResponse['repositoryName'] : compulsory. A human readable name for the repository;
|
||||||
|
* - $identifyResponse['baseURL'] : compulsory. The base URL of the repository;
|
||||||
|
* - $identifyResponse['protocolVersion'] : compulsory. The version of the OAI-PMH supported by the repository;
|
||||||
|
* - $identifyResponse['earliestDatestamp'] : compulsory. A UTCdatetime that is the guaranteed lower limit of all datestamps recording changes, modifications, or deletions in the repository. A repository must not use datestamps lower than the one specified by the content of the earliestDatestamp element. earliestDatestamp must be expressed at the finest granularity supported by the repository.
|
||||||
|
* - $identifyResponse['deletedRecord'] : the manner in which the repository supports the notion of deleted records. Legitimate values are no ; transient ; persistent with meanings defined in the section on deletion.
|
||||||
|
* - $identifyResponse['granularity'] : the finest harvesting granularity supported by the repository. The legitimate values are YYYY-MM-DD and YYYY-MM-DDThh:mm:ssZ with meanings as defined in ISO8601.
