Metacat

Add the code to delete systemmetadata.

Add a code to check if the pathquery engine is enabled in the checkIndexPaths method.

convert v2 SM to v1 SM for the v1 service call response

update to use v2 types for indexing

remove CN.systemMetadataChanged in favor of the CN.updateSystemMetadata method. Otherwise there's no good way to know where to fetch the auth copy from since the SM change might be to switch the authMN!

add support for v2 DataONE API.

remove dependency on HttpMessage that was in the utilities project but is now removed in favor of newer (standard) http client library code.

Include PDF version of the metadata in the package download. https://projects.ecoinformatics.org/ecoinfo/issues/6053

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
