Streams are list-like objects which contain multiple
Trace objects, i.e. gap-less continuous time series
and related header/meta information.
Each Trace object has the attribute
data pointing to a NumPy
ndarray of the actual time series and the attribute
which contains all meta information in a dict-like
Stats object. Both attributes
endtime of the Stats object are
A multitude of helper methods are attached to
for handling and modifying the waveform data.
Stream with an example seismogram can be created
read() without any arguments.
Local files can be read by specifying the filename, files stored on http
servers (e.g. at https://examples.obspy.org) can be read by specifying their
URL. For details and supported formats see the documentation of

Event metadata are handled in a hierarchy of classes closely modelled after the
de-facto standard format QuakeML.
See the IPython notebooks mentioned in the ObsPy Tutorial for
more detailed usage examples. See
Catalog.write() for supported
Station metadata are handled in a hierarchy of classes closely modelled after
the de-facto standard format
FDSN StationXML which was developed as a
human readable XML replacement for Dataless SEED.
