C.2. Importing and Exporting

When exporting content from a workspace with large Binary values, be sure to export using JCR's System View format. Only the System View treats properties as child elements. This allows each large value to be streamed (using buffered streams) into the XML element's content as a Base64-encoded string. Importing can also take advantage of streaming.

Exporting content using JCR's Document View results in all properties being treated as XML attributes, and various XML processing libraries treat large attributes poorly (e.g., using values that are in-memory String objects). Another critical disadvantage of the Document View is that it is unable to represent multi-valued properties, since attributes can have only one value.
