## BuiltInDocumentProperties class

A collection of built-in document properties.
To learn more, visit the [Work with Document Properties](https://docs.aspose.com/words/python-net/work-with-document-properties/) documentation article.




### Remarks

Provides access to [DocumentProperty](../documentproperty/) objects by their names (using an indexer) and
via a set of typed properties that return values of appropriate types.




The names of the properties are case-insensitive.

The properties in the collection are sorted alphabetically by name.




**Inheritance:** [BuiltInDocumentProperties](./) → [DocumentPropertyCollection](../documentpropertycollection/)

### Examples

Shows how to work with built-in document properties.

```python
doc = aw.Document(file_name=MY_DIR + 'Properties.docx')
# The "Document" object contains some of its metadata in its members.
print(f'Document filename:\n\t "{doc.original_file_name}"')
# The document also stores metadata in its built-in properties.
# Each built-in property is a member of the document's "BuiltInDocumentProperties" object.
print('Built-in Properties:')
for doc_property in doc.built_in_document_properties:
    print(doc_property.name)
    print(f'\tType:\t{doc_property.type}')
    # Some properties may store multiple values.
    if isinstance(doc_property.value, (list, tuple)):
        for value in doc_property.value:
            print(f'\tValue:\t"{value}"')
    else:
        print(f'\tValue:\t"{doc_property.value}"')
```
