Embedded Objects
From Apache OpenOffice Wiki
A TextEmbeddedObject is a com.sun.star.text.BaseFrame providing the interface com.sun.star.document.XEmbeddedObjectSupplier. The only method of this interface,
com::sun::star::lang::XComponent getEmbeddedObject ()
provides access to the model of the embedded document. That way, an embedded OpenOffice.org spreadsheet, drawing, chart or a formula document can be used in a text over its document model.
An embedded object is inserted by using the document's factory to create an instance of the the service com.sun.star.text.TextEmbeddedObject. The type of object is determined by setting the string property CLSID to an appropriate value before inserting the object as text content in the document.
