------------------------------------

             Summary: Add Excel Metadata as Implicit Fields
                 Key: DRILL-7723
                 URL: https://issues.apache.org/jira/browse/DRILL-7723
             Project: Apache Drill
          Issue Type: Improvement
          Components: Metadata, Storage - Text &amp; CSV
    Affects Versions: 1.17.0
            Reporter: Charles Givre
            Assignee: Charles Givre
             Fix For: 1.18.0


Excel files contain a significant number of metadata fields in them. This PR adds the ability to access these fields via implicit columns. The columns are:

_category
_content_status
_content_type;
_creator
_description
_identifier
_keywords
_last_modified_by_user
_revision
_subject
_title
_created
_last_printed
_modified

These fields are not projected in star queries so there is no effect on existing queries.
