extract EML creator[s] and use those names or organizations when registering DOI with EZID. https://github.nceas.ucsb.edu/KNB/arctic-data/issues/143
add support for v2 DataONE API.
take advantage of the ezidclient for multi-threaded/asynchronous DOI registration. This will be most useful for doing large batch updates and not so much for the one-at-a-time publish actions but works in either context. https://projects.ecoinformatics.org/ecoinfo/issues/6440
use a member instance of ezid service that only logs in every 24 hours (or other time TBD) instead of every time there is an interaction with the service. Saves us many calls when doing batch updates to ezid but keeps us from trying to use expired sessions. Motivated by https://projects.ecoinformatics.org/ecoinfo/issues/6440
Change the guid.ezid.uritemplate.metadata property value to the hostname only, with no context
use optional template for registering DOIs at a given target. https://projects.ecoinformatics.org/ecoinfo/issues/6092
use maven to manage most jar dependencies in Metacat.Exceptions include: LSID, Datamamager (EML),
include size and format datcite elements (optional) and use more general resourceType without formatId in them (Dataset/metadata and Dataset/data). http://schema.datacite.org/meta/kernel-2.2/doc/DataCite-MetadataKernel_v2.2.pdf
lookup the title for EML files when registering DOIs.lookup the creator from DataONE CN (if available).add EML-based test. http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5513
refactor DOI registration into separate class. http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5513
