| * This is an implementation of an unAPI for PICA-LBSs. | * Take an unique identifier as id-parameter and return bibliographic data |
| * It uses the XML-interface of the OPC4 for extracting bibliographic | * as COinS wrapped in JavaScript. |
| * data. | * For the specification of COinS, see <http://ocoins.info/>. |
| * For the specification of unAPI, see <http://unapi.info/specs/>. | |
