MdH Query Example:This example demonstrates how harvested metadata can be retrieved from a MdH Core and/orGlobal Search. It is also possible to query metadatafrom multiple MdH Cores: Read the createdParquet metadata fileThe Parquet Readercan handle different file systems,thus a file system connector is neededChoose a runningMdH CoreChoose a runningMdH Global SearchCreate a queryQuery metadataby using a corresponding query fileand retrieve the result into a KNIME data tableQuery metadataby using a corresponding query fileand stream the result to a file (e.g. json, parquet, sqlite, ...)Parquet Reader Local FileSystem Connector MdH Core Selection MdH GlobalSearch Selection Metadata QueryCreator MdH ExecuteQuery to String MdH ExecuteQuery to File MdH Query Example:This example demonstrates how harvested metadata can be retrieved from a MdH Core and/orGlobal Search.
