Java library for reading and writing Darwin Core Archive files. Formerly know as dwca-reader
Read an archive and display the scientific name of each records:
File myArchiveFile = new File("myArchive.zip");
File extractToFolder = new File("/tmp/myarchive");
Archive dwcArchive = ArchiveFactory.openArchive(myArchiveFile, extractToFolder);
Iterator<DarwinCoreRecord> it = dwcArchive.iteratorDwc();
DarwinCoreRecord dwc;
// loop over core darwin core records and display scientificName
while (it.hasNext()) {
dwc = it.next();
System.out.println(dwc.getScientificName());
}Read from a folder(extracted archive) and display the scientific name of each records + vernacular name(s) from the extension:
//WARNING: StarRecord requires underlying data files(including extensions) to be sorted by the coreid column
Archive dwcArchive = ArchiveFactory.openArchive(new File("/tmp/myarchive"));
System.out.println("Archive rowtype: " + dwcArchive.getCore().getRowType() + ", "
+ dwcArchive.getExtensions().size() + " extension(s)");
// loop over core darwin core star records
for (StarRecord rec : dwcArchive) {
System.out.println(rec.core().id() + " scientificName: " + rec.core().value(DwcTerm.scientificName));
if (rec.hasExtension(GbifTerm.VernacularName)) {
for (Record extRec : rec.extension(GbifTerm.VernacularName)) {
System.out.println(" -" + extRec.value(DwcTerm.vernacularName));
}
}
}The ArchiveFactory.openArchive method also supports the following file types:
- Single meta.xml file
- Single data file with terms as header
