Common Archive Observation Model - data engineering tools
caom2 module
The caom2 module is a library implementing the Common Archive
Observation Model (CAOM-2.3) for manipulating CAOM observations and
reading and writing XML documents.
http://www.opencadc.org/caom2/
To create a minimal Simple Observation
--------------------------------------
.. code:: python
import sys
from caom2 import SimpleObservation, TypedOrderedDict, Plane, Artifact,\
Part, Chunk, ObservationWriter, ProductType,\
ReleaseType, TypedList
observation = SimpleObservation('collection', 'observationID')
observation.planes = TypedOrderedDict(Plane)
plane = Plane('productID')
observation.planes['productID'] = plane
plane.artifacts = TypedOrderedDict(Artifact)
artifact = Artifact('uri:foo/bar', ProductType.SCIENCE, ReleaseType.META)
plane.artifacts['uri:foo/bar'] = artifact
artifact.parts = TypedOrderedDict(Part)
part = Part('name')
artifact.parts['name'] = part
part.chunks = TypedList(Chunk)
chunk = Chunk()
part.chunks.append(chunk)
writer = ObservationWriter()
writer.write(observation, sys.stdout)
The output:
