0.3.0

New features:

• This repository has been re-licensed under Apache 2.
• CASE 0.7.0 has been adopted.
• case-prov is now available on PyPI.
• case_prov_dot now has a flag --query-ancestry to specify a set of nodes for which the user wants to view ancestry.
• Any usage of the CASE concepts investigation:wasDerivedFrom and investigation:wasInformedBy are now mapped directly into PROV, to assist with chain-of-custody review. (Usage of the CASE concepts that is not also supported by CASE InvestigativeActions and ProvenanceRecords will render as dashed lines in the PROV-O translation illustration.)

Updated documentation:

• The prov:Derivation construction query now documents that it intentionally creates a prov:Derivation per prov:entity predicate usage.

Updates for developers:

• A CODEOWNERS file has been added.
• case-utils is now imported via PyPI.
• Code-review tools black, flake8, and isort are now run with pre-commit, and pre-commit has been added to Continuous Integration.
• Unit tests within this repository now require Java >= 11, due to the toolset upgrade in UCO Issue 373.
• This repository now runs Continuous Integration tests on the same Python versions as case-utils.

Fixes:

• The prov:Communication and prov:wasInformedBy construction queries received a logic fix and speed ugprade.

0.2.0

This release adopts CASE 0.6.0, by adopting the case_utils 0.4.0 release.

Some command interface changes have been made since the prior release:

• The argument order for case_prov_rdf and case_prov_dot now take the output file as the first argument, and the input graph files as the second and onward.
  • The commands now also accept multiple input graph files, aligning their behavior with other commands from case_utils.

Some input data behaviors have changed since the prior release:

• The CASE ProvenanceRecord is now incorporated into prov:wasInformedBy construction.
• CASE InvestigativeActions that had an instrument but no performer now report the instrument as the prov:Agent.

Some output effects have changed since the prior release:

• Per PROV convention found since the initial release, figures now have a temporal flow from top to bottom, which is reversed from the initial release.
• A bug with multiple-edge display has been corrected.

Some developer quality-of-life implementations have been made:

• Unit tests called with make check are now run as part of Continuous Integration (CI).
• Unit tests now use venv instead of virtualenv.
• The CASE "Crossover" scenario has been added to the usage demonstration in this repository.
• Code in this repository is now formatted with black, and checked with CI.
• Code in this repository is now statically type-checked with mypy, and checked with CI.
