README

Births, baptisms, marriages, deaths, burials and more from the indexes of some two hundred Dutch and Belgian archives, through Open Archives, for omnisense/omnistate.

$registry = new OpenArchieven($httpClient);
$lines = $registry->search(new CivilQuery(familyName: 'van Gogh', givenName: 'Vincent Willem', dated: Period::year(1853), kinds: [CivilRecordKind::BIRTH]));
$act = $registry->find($lines[0]->identifier);      // "bhi:78a37833-…"
$act->persons;            // the child, the mother, the father - each with its role
$act->archive;            // Brabants Historisch Informatie Centrum, Geboorteregister Zundert 1853, n° 29
$act->images;             // the scan of the act

No framework needed: the package requires omnisense/omnistate and symfony/http-client. $httpClient is the HTTP client to call with - the application's, HttpClient::create() in plain PHP, a MockHttpClient in a test.
