Metacat

implement query description for pathquery -- only tells callers about the pre-indexed paths we have in Metacat since there are an infinite number of "fields" when storing arbitrary XML, but we really don't want people using non-indexed paths for performance reasons anyway. I've typed all the fields as String, even though some are not just strings and can be used for numeric or data comparisons.

Implement MNQuery for "pathquery" engine. Optionally include guid in the pathquery results (https://redmine.dataone.org/issues/3083)

update pub_date when the length of that field is != 4 (use date_created in this scenario). There were 2 entries that had "193" as the pub_date.

replace new lines in creator with spaces. set blank " " titles and creators to "unknown". use "Baltimore Ecosystem Study LTER" for publisher on all BES objects.

include John Kunze's latest suggestions for improved metadata -- a lot of clean-up, especially on characters in the file. Note UTF-8 encoding of the script.

include note about pathquery performance fix (when using indexed fields)

use ObjectFormatInfo libclient utility to look up mimeType and filename extension during get() calls. Configurable mapping file is deployed by default to /var/metacat/dataone where it can then be augmented as needed. This location is controlled in the metacat.properties file (which is injected into the DataONE Settings values during weapp intitialization)....

add count for the total processed pids (from ISet iterator)

handle /object?count=0 queries using simpler (quicker) sql

allow getlog action to use docid parameters that do not include revision. In these cases, the latest revision will be used.
