OAI validation error

rauf · July 28, 2016, 12:44pm

Hello,

I’m receiving the following error when I try to index a journal at the OAI Register:

[1] Failed to extract error code from the response to request:
verb=ListRecords&metadataPrefix=oai_dc&until=2014-04-29T19:09:55Z The request
specified a date one year before the earliestDatestamp given in the Identify
response. There should therefore not be any records with datestamps on or
before this date and a noRecordsMatch error code should be returned.

The full error log is available here:
http://www.openarchives.org/Register/ValidateSite?log=1156

My ojs version is 2.4.8

Hi @rauf,

the record deleted policy is set to persistent and thus deleted record stubs are retrievable, but the earliest datestamp seems to taken from the active records. The earliest of these is younger than some of the deleted records you got.

Hope this helps

Hi @cjuergen, thanks for your answer, but how can I fix this?

Hi @rauf,

I’m new to OJS and PHP so I cant’t provide a code but I think it happens here:

github.com

pkp/pkp-lib/blob/ojs-stable-2_4_8/classes/oai/PKPOAIDAO.inc.php#L57


	 * in hierarchical order. If empty, all records from
	 * all sets will be included.
	 * @return int
	 */
	function getEarliestDatestamp($selectStatement, $setIds = array()) {
		$params = $this->getOrderedRecordParams(null, $setIds);

		$result =& $this->retrieve(
			$selectStatement . ' as the_date FROM mutex m ' .
			$this->getRecordJoinClause(null, $setIds) . ' ' .
			$this->getAccessibleRecordWhereClause() . 
			'ORDER BY the_date',
			$params
		);

		if (isset($result->fields[0])) {
			$timestamp = strtotime($this->datetimeFromDB($result->fields[0]));
		}
		if (!isset($timestamp) || $timestamp == -1) {
			$timestamp = 0;
		}

Maybe you can file an issue at Issues · pkp/pkp-lib · GitHub and it will be fixed in a future release.
