Description:
pycdstar 1.1.0
pycdstar
Python client library for CDStar
Usage
from pycdstar.api import Cdstar
# Initialize a client object, with connection info from a config file
cdstar = Cdstar()
# create a new object
obj = cdstar.get_object()
# with initially no associated metadata
assert obj.metadata is None
# assigning to the metadata property will create a metadata record
obj.metadata = {"creator": "pycdstar"}
# retrieve the now existing object
obj = cdstar.get_object(obj.id)
assert 'creator' in obj.metadata
# again, initially the bitstreams property is an empty list
assert not obj.bitstreams
# we add a bitstream by uploading a local file
bitstream = obj.add_bitstream(fname='README.txt')
# and re-read the object
obj.read()
# a bitstreams read method returns an iterator to allow for streaming,
# i.e. chunked downloads
assert ''.join(list(bitstream.read()))
assert len(obj.bitstreams) == 1
# to make sure the newly created resources are properly indexed, we allow
# for a short delay
sleep(1)
# now we search for a string we know to exist in the uploaded bitstream
res = cdstar.search('ssh')
assert len(res)
# the first element in the search results list has the bitstream as
# associated resource
assert 'ssh' in ''.join(list(res[0].resource.read()))
query = 'pycdstar'
res = cdstar.search(query, index='metadata')
assert len(res)
res = cdstar.search(query, index='fulltext')
assert not len(res)
bitstream.delete()
obj.delete()
