Common to SDMX 2.1 and 3.0#

sdmx.model.internationalstring.DEFAULT_LOCALE = 'en'[source]#: Default locale for InternationalString.

class sdmx.model.internationalstring.InternationalString(value: str | Sequence | Mapping | Iterable[Tuple[str, str]] | None = None, **kwargs)[source]#

Bases: object

SDMX-IM InternationalString.

SDMX-IM LocalisedString is not implemented. Instead, the ‘localizations’ is a mapping where:

keys correspond to the ‘locale’ property of LocalisedString.
values correspond to the ‘label’ property of LocalisedString.

When used as a type hint with pydantic, InternationalString fields can be assigned to in one of four ways:

@dataclass
class Foo:
     name: InternationalStringDescriptor() = InternationalStringDescriptor()

# Equivalent: no localizations
f = Foo()
f = Foo(name={})

# Using an explicit locale
f.name['en'] = "Foo's name in English"

# Using a (locale, label) tuple
f.name = ('fr', "Foo's name in French")

# Using a dict
f.name = {'en': "Replacement English name",
          'fr': "Replacement French name"}

# Using a bare string, implicitly for the DEFAULT_LOCALE
f.name = "Name in DEFAULT_LOCALE language"

Only the first method preserves existing localizations; the latter three replace them.

localizations: Dict[str, str] = {}[source]#

localized_default(locale=None) → str[source]#: Return the string in locale, or else the first defined.

class sdmx.model.internationalstring.InternationalStringDescriptor[source]#: Bases: object

Information Model classes common to SDMX 2.1 and 3.0.

This module implements many of the classes described in the SDMX-IM specification (‘spec’), which is available from:

Details of the implementation:

Python dataclasses and type hinting are used to enforce the types of attributes that reference instances of other classes.
Some classes have convenience attributes not mentioned in the spec, to ease navigation between related objects. These are marked “sdmx extension not in the IM.”
Class definitions are grouped by section of the spec, but these sections occasionally appear out of order so that classes are defined before they are referenced by others.

Parameters:: strict (bool, optional) – Passed to ComponentList.compare().

dimensions: DimensionDescriptor[source]#: A DimensionDescriptor that describes the dimensions of the data structure.

classmethod from_keys(keys)[source]#

Return a new DSD given some keys.

The DSD’s dimensions refers to a set of new Concepts and Codelists, created to represent all the values observed across keys for each dimension.

Parameters:: keys (iterable of Key) – or of subclasses such as SeriesKey or GroupKey.

group_dimensions: DictLikeDescriptor[str, GroupDimensionDescriptor] = None[source]#: Mapping from GroupDimensionDescriptor.id to GroupDimensionDescriptor.

iter_keys(constraint: BaseConstraint | None = None, dims: List[str] = []) → Generator[Key, None, None][source]#

Iterate over keys.

Parameters:

constraint (Constraint, optional) – If given, only yield Keys that are within the constraint.
dims (list of str, optional) – If given, only iterate over allowable values for the Dimensions with these IDs. Other dimensions have only a single value like “(DIM_ID)”, where DIM_ID is the ID of the dimension.

make_constraint(key)[source]#

Return a constraint for key.

key is a dict wherein:

keys are str ids of Dimensions appearing in this DSD’s dimensions, and
values are ‘+’-delimited str containing allowable values, or iterables of str, each an allowable value.

For example:

cc2 = dsd.make_constraint({'foo': 'bar+baz', 'qux': 'q1+q2+q3'})

cc2 includes any key where the ‘foo’ dimension is ‘bar’ or ‘baz’, and the ‘qux’ dimension is one of ‘q1’, ‘q2’, or ‘q3’.

Returns:: A constraint with one CubeRegion in its data_content_region , including only the values appearing in key.
Return type:: ContentConstraint
Raises:: ValueError – if key contains a dimension IDs not appearing in dimensions.

make_key(key_cls, values: Mapping, extend=False, group_id=None)[source]#

Make a Key or subclass.

Parameters:

key_cls (Key or SeriesKey or GroupKey) – Class of Key to create.
values (dict) – Used to construct Key.values.
extend (bool, optional) – If True, make_key will not return KeyError on missing dimensions. Instead dimensions (key_cls is Key or SeriesKey) or group_dimensions (key_cls is GroupKey) will be extended by creating new Dimension objects.
group_id (str, optional) – When key_cls is :class`.GroupKey`, the ID of the GroupDimensionDescriptor that structures the key.

Returns:

An instance of key_cls.

Return type:

Key

Raises:

KeyError – If any of the keys of values is not a Dimension or Attribute in the DSD.

Organization contact information.

IMF is the only known data provider that returns messages with Contact information. These differ from the IM in several ways. This class reflects these differences:

‘name’ and ‘org_unit’ are InternationalString, instead of strings.
‘email’ may be a list of e-mail addresses, rather than a single address.
‘fax’ may be a list of fax numbers, rather than a single number.
‘uri’ may be a list of URIs, rather than a single URI.
‘x400’ may be a list of strings, rather than a single string.

Bases: MaintainableArtefact, Generic[IT]

SDMX-IM Item Scheme.

The IM states that ItemScheme “defines a set of Items…” To simplify indexing/retrieval, this implementation uses a dict for the items attribute, in which the keys are the id of the Item.

Because this may change in future versions, user code should not access items directly. Instead, use the getattr() and indexing features of ItemScheme, or the public methods, to access and manipulate Items:

>>> foo = ItemScheme(id='foo')
>>> bar = Item(id='bar')
>>> foo.append(bar)
>>> foo
<ItemScheme: 'foo', 1 items>
>>> (foo.bar is bar) and (foo['bar'] is bar) and (bar in foo)
True

append(item: IT)[source]#

Add item to the ItemScheme.

Parameters:: item (same class as items) – Item to add.

compare(other, strict=True)[source]#

Return True if self is the same as other.

Two ItemSchemes are the same if:

MaintainableArtefact.compare() is True, and
their items have the same keys, and corresponding Items compare equal.

Parameters:: strict (bool, optional) – Passed to compare() and MaintainableArtefact.compare().

extend(items: Iterable[IT])[source]#

Extend the ItemScheme with members of items.

Parameters:: items (iterable of Item) – Elements must be of the same class as items.

get_hierarchical(id: str) → IT[source]#: Get an Item by its hierarchical_id.

is_partial: bool | None = None[source]#

items: Dict[str, IT][source]#: Members of the ItemScheme. Both ItemScheme and Item are abstract classes. Concrete classes are paired: for example, a Codelist contains Codes.

setdefault(obj=None, **kwargs) → IT[source]#

Retrieve the item name, or add it with kwargs and return it.

The returned object is a reference to an object in the ItemScheme, and is of the appropriate class.

class sdmx.model.common.Key(arg: Mapping | Sequence[KeyValue] | None = None, **kwargs)[source]#

Bases: object

SDMX Key class.

The constructor takes an optional list of keyword arguments; the keywords are used as Dimension or Attribute IDs, and the values as KeyValues.

For convenience, the values of the key may be accessed directly:

>>> k = Key(foo=1, bar=2)
>>> k.values['foo']
1
>>> k['foo']
1

Parameters:

dsd (DataStructureDefinition <.BaseDataStructureDefinition>) – If supplied, the dimensions and attributes are used to separate the kwargs into KeyValues and AttributeValues. The kwargs for described_by, if any, must be dimensions or appear in group_dimensions.
kwargs – Dimension and Attribute IDs, and/or the class properties.
