• Going forward we will tie our Bulk Data models to our versioned APIs to be able to better communicate enhancements and future breaking changes.

• The OpenLaws Bulk Data JSONL now conforms with the API 1.0.3 Division model

• Added to the Division model:

  • display_ancestors - New display_ancestors field added to Division to help users render breadcrumbs or add context for an LLM for where the Division exists in the law's hierarchy.

  • display_children - Children of the current Divison node which allows users to traverse the “tree” of Divisions

  • web_view_url - A static webpage with a beautifully rendered view of the current Division which can be used a Copilot or Deep Research style citation.

• Breaking changes in Division model:

  • The default value changed for the effective_date_start and effective_date_end fields. Previously, missing/null values previous were null . However, they’re now data modeled to be more closely modeled to the domain as “-Infinity” for effective_date_start and “Infinity” for effective_date_end.
