How to Determine the Name of a SharePoint Metadata Tag
Note: If the tags entered do not correspond to the metadata names of the appropriate SharePoint fields, erroneous or blank results are returned by queries (ex.: the content and summary can be blank and the author name missing).
To determine the metadata name of a column
In SharePoint, access the page where the list is displayed.
Click the column name.
In the Address field of the browser, locate the expression SortField=. The name of the column is the expression entered after = (i.e. SortField=Name).
Example: In the image above, the metadata name of the Article ID column is Article_x0020_ID (%5f indicates an underscore and must be replaced by its value in the tag).
