This library is intended to generate a filtered record from a REST/Http metadata provider response (to mine a REST response a.k.a. remi). The code base was part of Semantic Cite and is now being deployed as independent library. Supported providers are:

  • CrossRef (DOI)
  • VIAF
  • PubMed (PMID and PMCID)
  • OCLC (WorldCat)
  • OpenLibrary (OLID, ISBN)


PHP 5.3 / HHVM 3.5 or later


The recommended installation method for this library is to add the dependency to your composer.json.

	"require": {
		"onoi/remi": "~0.4"


use Onoi\HttpRequest\HttpRequestFactory;
use Onoi\Remi\FilteredHttpResponseParserFactory;

$httpRequestFactory = new HttpRequestFactory()

$filteredHttpResponseParserFactory = new FilteredHttpResponseParserFactory(
$crossRefFilteredHttpResponseParser = $filteredHttpResponseParserFactory->newCrossRefFilteredHttpResponseParser(
	new FilteredRecord()

$crossRefFilteredHttpResponseParser->doFilterResponseById( '10.1126/science.1152662' );
$filteredRecord = new FilteredRecord();
$filteredRecord->setRedactedFields( array( 'pages', 'abstract' ) );

$pubMedFilteredHttpResponseParser = $filteredHttpResponseParserFactory->newNcbiPubMedFilteredHttpResponseParser(

$pubMedFilteredHttpResponseParser->doFilterResponseById( '19782018' );
  • The FilteredHttpResponseParser (implementing the ResponseParser interface) returns a simple array filtered from a REST response.
  • FilteredHttpResponseParser::doFilterResponseById is not expected to make any input validation (in terms of format or range) for the requested response therefore the implementing class is responsible for an appropriate validation process.
  • FilteredRecord::setRedactedFields can be used to remove selected fields from the record.
  • It is further possible to invoke a CachedCurlRequest to avoid repeated requests to the same REST API url.
