Tim Allison commented on TIKA-3721:
-----------------------------------
Tika's SummaryExtractor (based on POI) works on these files.
{noformat}
for (File f : new File("....tika-dgn-detector/src/test/resources/dgn" +
"/dgn8").listFiles() ) {
POIFSFileSystem pfs = new POIFSFileSystem(f, true);
DirectoryNode root = pfs.getRoot();
System.out.println("file: " + f.getName());
Metadata metadata = new Metadata();
SummaryExtractor summaryExtractor = new SummaryExtractor(metadata);
summaryExtractor.parseSummaries(root);
System.out.println("ENTRIES");
for (Iterator<Entry> it = root.getEntries(); it.hasNext(); ) {
Entry e = it.next();
String which = "directory";
if (e instanceof DocumentEntry) {
which = "document";
}
System.out.println(e.getName() + " : " + which);
}
System.out.println("METADATA");
debug(metadata);
System.out.println("");
