Filters
From OkapiWiki
Filters are the components that convert input documents from their native file format into a common internal set of resources that all Okapi components use. The extracted content can be re-written into the original file format. When using the steps, the extraction is done by the Raw Document to Filter Events Step and the re-writing by the Filter Events to Raw Document Step.
Note: The Okapi Filters Plugin for OmegaT allows you to use some of the filters directly from OmegaT.
