A property, or piece of metadata, is a granular data element stored on a document. Properties may come in a variety of forms, including the following:
- Text properties are strings.
- Date properties are dates.
- Yes/no properties are Booleans.
- Numbered properties are integers.
- Blobs are containers for binary content, such as files.
In addition, properties may be a list of any of these forms, such as a list of dates. If properties have a more complex structure, such as a list of contacts, they are considered complex properties.
