spacepy.datamodel.SpaceData

class spacepy.datamodel.SpaceData(*args, **kwargs)

Datamodel class extending dict by adding attributes.

Although the format of attributes is not enforced, using ISTP metadata enables the use of methods from ISTPContainer.

__init__(*args, **kwargs)

Base class for “Data Model” representation data

Abstract method, reimplement

Attributes:

attrsdict

dictionary of the attributes of the SpaceData object

Methods

flatten()	Method to collapse datamodel to one level deep
toCDF(**kwargs)	Create CDF file from this SpaceData.
toHDF5(**kwargs)	Create HDF5 file from this SpaceData.
toJSONheadedASCII(**kwargs)	Create JSON-headed ASCII file from this SpaceData.
tree(**kwargs)	Print the contents of the SpaceData object in a visual tree

flatten()

Method to collapse datamodel to one level deep

Examples

>>> import spacepy.datamodel as dm
>>> import spacepy.toolbox as tb
>>> a = dm.SpaceData()
>>> a['1'] = dm.SpaceData(dog = 5, pig = dm.SpaceData(fish=dm.SpaceData(a='carp', b='perch')))
>>> a['4'] = dm.SpaceData(cat = 'kitty')
>>> a['5'] = 4
>>> a.tree()
