To add data to a metsrw.METSDocument, create and append metsrw.FSEntry objects.
>>> mets = metsrw.METSDocument() >>> directory_1 = metsrw.FSEntry(label="test", path="test", type="Directory") >>> file_1 = metsrw.FSEntry( ... label="hello.pdf", path="test/hello.pdf", type="Item", ... file_uuid=str(uuid.uuid4())) >>> directory_1.children.append(file_1) >>> file_2 = metsrw.FSEntry( ... label="demo.jpg", path="test/demo.jpg", type="Item", ... file_uuid=str(uuid.uuid4())) >>> directory_1.children.append(file_2) >>> mets.append_file(directory_1) >>> mets.all_files() {FSEntry(...), FSEntry(...)}
Adding metadata is done via the metsrw.FSEntry.
- file_1 = metsrw.FSEntry(
label="hello.pdf", path="test/hello.pdf", type="Item", file_uuid=str(uuid.uuid4()))
file_1.add_premis_object("<premis>object</premis>") file_1.add_premis_event("<premis>event</premis>") file_1.add_premis_agent("<premis>agent</premis>") rights = file_1.add_premis_rights("<premis>rights</premis>") dc = file_1.add_dublin_core("<dublincore>metadata</dublincore>")
# Replaces added metadata rights.replace_with(file_1.add_premis_rights("<premis>newer rights</premis>"))
metsrw supports serialization to file, bytes or lxml Element object.
serialization
temp_dir = tempfile.mkdtemp() output_path = os.path.join(temp_dir, "demo.xml") mets = metsrw.METSDocument() file1 = metsrw.FSEntry("hello.pdf", file_uuid=str(uuid.uuid4())) mets.append_file(file1)
serialization
os.remove(output_path) os.removedirs(temp_dir)
serialization
>>> mets = metsrw.METSDocument() >>> file1 = metsrw.FSEntry("hello.pdf", file_uuid=str(uuid.uuid4())) >>> mets.append_file(file1)
# To file on disk >>> mets.write(output_path)
# To _Element object >>> mets.serialize() <Element {http://www.loc.gov/METS/}mets ...>
# To bytes >>> mets.tostring() b'<?xml version='1.0' encoding='UTF-8'?>n<mets:mets ...'
