This address enhancement issue #28

[tosfos]

This patch works as is. It should be configured similar to:

$GLOBALS['smwgQuerySources'] = array(
    'somewiki' => 'SMWExternalAskQueryLookup',
);

$GLOBALS['seqlgExternalRepositoryEndpoints'] = array(
    'somewiki' => array(
        'http://somewiki.local/w/index.php/$1',
        'http://somewiki.local/w/api.php',
        true
    )
);

$GLOBALS['seqlgExternalRepositoryCredentials'] = array(
    'somewiki' => array(
        'username' => 'Admin@Remote',
        'password' => 'awdawda3ra34fs4faserfsefdasefsef'
    )
);

// Define constants for my additional namespaces.
define("NS_PROTECTED_QUERY", 3000);
define("NS_PROTECTED_QUERY_TALK", 3001);

// Add namespace
$wgExtraNamespaces[NS_PROTECTED_QUERY] = "ProtectedQuery";
$wgExtraNamespaces[NS_PROTECTED_QUERY_TALK] = "ProtectedQuery talk";

$GLOBALS['seqlgExternalQueryEnabledNamespaces'] = array(
    NS_PROTECTED_QUERY
);

... But in order to get the "enabled namespaces" feature working, the attached patch to SemanticMediaWiki (version 3) is required. The patch is based off of SMW commit b14c053 .
