You can map custom XMP (Extensible Metadata Platform) metadata fields to custom Alfresco data model properties using alfresco-global.properties.

Ensure that you have installed the required external and internal software before configuring the transformer. See Prerequisites for using Media Management for more information.

1. Stop the Alfresco server.

2. Edit your alfresco-global.properties file to specify your custom metadata properties, for example:

   metadata.extracter.TikaExifTool.extract.namespace.prefix.cm=http://www.alfresco.org/model/content/1.0
   metadata.extracter.TikaExifTool.extract.namespace.prefix.custom=http://example.com/model/custom/1.0
   metadata.extracter.TikaExifTool.extract.XMP-custom\:Text=custom:text
   # Force multi-line parsing with []
   metadata.extracter.TikaExifTool.extract.XMP-custom\:TextML[]=custom:textMultiLine
   metadata.extracter.TikaExifTool.extract.XMP-custom\:Date=custom:date
   metadata.extracter.TikaExifTool.extract.XMP-custom\:Integer=custom:integer
   metadata.extracter.TikaExifTool.extract.XMP-custom\:ClosedChoice=custom:closedChoice
   metadata.extracter.TikaExifTool.extract.XMP-custom\:OpenChoice=custom:openChoice
   metadata.extracter.TikaExifTool.extract.XMP-custom\:Boolean=custom:boolean
   

   A sample alfresco-global.properties file is shipped in the root folder of the Media Management distribution zip, which defines custom properties.

   The metadata.extracter.TikaExifTool.extract.XMP-custom\:Text attribute specifies simple text fields. The metadata.extracter.TikaExifTool.extract.XMP-custom\:TextML[] attribute specifies multi-line text fields for metadata extraction.

3. Start your Alfresco server to apply the changes.
