The following information is derived from the plugin description.

Adds support for parsing OpenDocument Text documents based on the OASIS OpenDocument Format. This plugin is required to embed ODT files into an i-net Clear Reports report and to compare ODT documents using i-net PDFC.

The OpenDocument Format is an open standard for office documents and is used by applications such as LibreOffice and Apache OpenOffice. This plugin currently supports text documents in ODT format.

In i-net PDFC it provides the basis for comparing ODT document content. Depending on features used by the source application, rendering differences may still occur.
