Metacat

simple autogen-based implementation of MN.generateIdentifier(). does not support DOIs, ARKs, etc. It does support including a fragment, returning an identifier like "<fragment>.2012113010215298206"

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

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)....

improve content type handling during the get() calls

Print the stack trace when the MMP cannot be resolved.

use metacat.properties to specify the default checksum algorithm to use -- this way it will be easy for us to switch to whatever DataONE decrees.
