samvera/ldp#136 has been opened, and samvera/active_fedora#1470 can be advanced based upon this.

[jrgriffiniii]

https://github.com/samvera/active_fedora/compare/issues-1470-jrgriffiniii-ruby3.0 replaces solr_wrapper and fcrepo_wrapper with docker-compose for local development. However, tests are still failing due to the need to upgrade active-triples

[jrgriffiniii]

samvera-labs/ActiveTriples#6 provides the updates needed for active-triples needed for the upgrade.
