caom2utils 1.7.1

Observation Validation

Validates a CAOM2 element (Observation, Plane, Artifact, Part or Chunk) with respect to the attributes of the element and possibly all its sub-elements. Example of validations: attribute values, spherical geometry of planes, WCS of chuncks, etc.

import sys
from caom2 import SimpleObservation
import caom2utils

obs = SimpleObservation('collection', 'observationID')

# change and update obs

try:
    caom2utils.validate(obs)
except Exception:
    print('My exception is not valid')

                                          information for an observation. Specifying this flag
                                          skips that step.

optional arguments:
   --blueprint BLUEPRINT [BLUEPRINT ...]  list of files with blueprints for CAOM2
                                          construction, in serialized format. If
                                          the list is of length 1, the same
                                          blueprint will be applied to all lineage
                                          entries. Otherwise, there must be a
                                          blueprint file per lineage entry.
   --caom_namespace CAOM_NAMESPACE        if this parameter is specified, over-ride
                                          the default CAOM2 version when writing
                                          XML. The default is the latest version of
                                          CAOM2.3.
   --cert CERT                            location of your X509 certificate to use
                                          for authentication (unencrypted, in PEM

   --external_url EXTERNAL_URL [EXTERNAL_URL ...]
                                          service endpoint(s) that return(s) a
                                          string that can be made into FITS
                                          headers. Cardinality should be consistent
                                          with lineage.
   -h, --help                             show this help message and exit
   --host HOST                            base hostname for services - used mainly

                                          identifiers that will be created for the
                                          identified observation.
   --local LOCAL [LOCAL ...]              list of files in local filesystem (same
                                          order as uri)
   --module MODULE                        if the blueprint contains function calls,
                                          call importlib.import_module for the named
                                          module. Provide a fully qualified name.
                                          Parameter choices are the artifact URI (uri)
                                          or a list of astropy Header instances
                                          (header). This will allow the update of a
                                          single blueprint entry with a single call.
   -n                                     use .netrc in $HOME for authentication
   --netrc-file NETRC_FILE                netrc file to use for authentication
   --no_validate                          by default, the application will validate
                                          the WCS information for an observation.
                                          Specifying this flag skips that step.
   --not_connected                        if set, there is no internet connection,
   so skip service invocations.
   --observation collection observationID observation in a collection
   -o, --out OUT_OBS_XML                  output of augmented observation in XML
   --plugin PLUGIN                        if this parameter is specified, call
                                          importlib.import_module for the named
                                          module. Then execute the method "update",
                                          with the signature (Observation, **kwargs).
                                          This will allow for the update of multiple
                                          observation data members with one call.
   -q, --quiet                            run quietly

                                          productID/artifactURI. List of lineage
                                          entries that will be processed with a
                                          BlueprintParser. Good for files with no
                                          metadata in the content.
   -u, --user USER                        name of user to authenticate. Note:
                                          application prompts for the corresponding
                                          password!
