Metadata extractors

1. Metadata extractors

Allows you to add elements to Constellio and extract their metadata, either by using styles, regular checkouts, or properties. The order of priority for populating a metadata is defined in the system configurations. If no data is defined for styles and regular expressions by the metadata extractor, Constellio will automatically export the property data. 

Here is the form to fill out to define styles, properties, and regular expressions for a specific metadata: 

It is useful for accurate metadata to specify extraction information in all three methods (styles, properties, and regular expressions). However, for a specific Word template with styles, it may also be useful to create a metadata schema specific to that template and define precisely how to retrieve each metadata with one or more Word styles or templates.
