      public BranchEditService(org.apache.jena.query.Dataset assertions, BranchRepository branchRepository)

      branchRepository - guards every operation against an unknown branch

  • Method Details

    • updateBranch

      public boolean updateBranch(String branch, List<ai.chatur.cortex.BranchChange> changes)
      Applies reviewer changes — deletions and object edits — to the assertions staged on the given branch, as an RDF patch on the branch graph.

      When the deletions remove every statement a subject carried, its IRI is gone from the branch, so every staged statement referencing that IRI as object is deleted as well.

      Changes addressing the provenance activity of the branch are ignored.

      Parameters:
      branch - the branch name
      changes - the changes to apply
      Returns:
      true if the branch existed and the changes were applied

    • renameBranchSubjects

      public boolean renameBranchSubjects(String branch, List<ai.chatur.cortex.BranchRename> renames)
      Renames subjects staged on the given branch, as an RDF patch on the branch graph.

      Every staged statement referencing a renamed IRI as object is rewritten to reference the new IRI; the statements describing the renamed subject — those carrying the IRI as subject — are removed rather than rewritten.

      Renames addressing the provenance activity of the branch are ignored.

      Parameters:
      branch - the branch name
      renames - the renames to apply
      Returns:
      true if the branch existed and the renames were applied
