AEM 62 - Add Multifield to Assets Metadata Schema Editor

Goal

This post is a no-code simple hack method to add multifield (with pathbrowser) to metadata schema editor

Package Install

Solution

1) To add a metadata field to the image/jpeg editor; access jpeg metadata schema editor

http://localhost:4502/mnt/overlay/dam/gui/content/metadataschemaeditor/schemadetails.html/default/image/jpeg?formPath=/conf/global/settings/dam/adminui-extension/metadataschema

2) Drag a Text Field with label Related Images mapping to the property ./jcr:content/metadata/relatedImages in new tab, here EAEM

3) Saved in CRX eg. /conf/global/settings/dam/adminui-extension/metadataschema/default/image/jpeg/items/tabs/items/tab4/items/col1/items/1474558552884

4) Manually, change the saved metadata field to multifield (with pathbrowser) - granite/ui/components/foundation/form/multifield

<_x0031_474558552884
 jcr:primaryType="nt:unstructured"
 sling:resourceType="granite/ui/components/foundation/form/multifield"
 fieldLabel="Related Images"
 renderReadOnly="true">
 <granite:data
  jcr:primaryType="nt:unstructured"
  metaType="text"/>
 <field
  jcr:primaryType="nt:unstructured"
  sling:resourceType="granite/ui/components/coral/foundation/form/pathbrowser"
  name="./jcr:content/metadata/relatedImages"/>
</_x0031_474558552884>

4) The user can now select multiple paths saved to jpeg image metadata eg. /content/dam/geometrixx-outdoors/activities/snowboarding/PDP_1_c05.jpg/jcr:content/metadata/relatedImages
