Package net.sf.exorcist.core.zip Description

Plugins for the Exorcist content state file format.

This package contains the exporter and importer plugins for reading and writing Exorcist content state files. A content state file is a Zip archive that includes the full contents of a ContentState instance. Such files can be used for easily backing up or for example emailing selected parts of a content repository. The Exorcist content state file format is specified below in more detail.

The Exorcist content state file format

An Exorcist content state file is a Zip archive that contains one or more files that represent the contents of a ContentState instance. These files are the required content.xml file that contains the serialized XML content tree document, and the optional binary attachment files named data/A/B/C, where A is the first two letters, B the next two letters, and C all the letters of the 32 (lowercase) hex digit representation of the SHA-1 content hash of an attachment.

The content state files use the normal .zip file extension and contain no special format identifiers. A standard Zip file is a content state file if it contains the content.xml file and all the attachment files referenced by the XML content tree document.
