AEM asset metadata delete.

Hi @jezwn, I am not sure what exactly is your case, and if this is one time activity or something you would like to proceed regularly. Anyway, below you can find simple groovy script that will remove dc:description completely or just erase the value.

import javax.jcr.query.Query
import org.apache.sling.api.resource.ModifiableValueMap

def query = "SELECT * FROM [dam:Asset] AS s WHERE ISDESCENDANTNODE([/content/dam]) and s.[jcr:content/metadata/dc:description] IS NOT NULL"

resourceResolver.findResources(query, Query.JCR_SQL2).each { r ->
    def mvp = r?.getChild("jcr:content/metadata")?.adaptTo(ModifiableValueMap.class)
    if(mvp) {
        // remove dc:description prpeorty
        // mvp.remove("dc:description")
        
        // erase dc:description property value
        mvp.put("dc:description", "")
    }
    resourceResolver.commit()
}
