Example 1 with XMPPacketScanner

use of org.apache.tika.parser.image.xmp.XMPPacketScanner in project stanbol by apache.

the class XmpExtractorEngine method computeEnhancements.

@Override
public void computeEnhancements(ContentItem ci) throws EngineException {
    InputStream in = ci.getBlob().getStream();
    XMPPacketScanner scanner = new XMPPacketScanner();
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    try {
        scanner.parse(in, baos);
    } catch (IOException e) {
        throw new EngineException(e);
    }
    byte[] bytes = baos.toByteArray();
    if (bytes.length > 0) {
        Graph model = new IndexedGraph();
        parser.parse(model, new ByteArrayInputStream(bytes), "application/rdf+xml");
        GraphNode gn = new GraphNode(new IRI("http://relative-uri.fake/"), model);
        gn.replaceWith(ci.getUri());
        ci.getLock().writeLock().lock();
        try {
            LOG.info("Model: {}", model);
            ci.getMetadata().addAll(model);
        } finally {
            ci.getLock().writeLock().unlock();
