SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill builds a clear chronology from declared litigation document sources and uploads, extracting dated events, removing duplicates, and tagging each event by significance so counsel can draft facts and statements of events faster.

Core Features & Use Cases

  • Matter- or production-centric timelines: Choose matter-mode (pull facts from the matter’s theory and doc landscape) or documents-mode (extract from a production/Bates/eDiscovery export).
  • Document-governed event extraction: Reads PDFs, emails, DOCX/TXT, connector-accessible archives, and production exports to extract dated events with attribution to the originating source.
  • De-duplication + significance tagging: Merges repeated events across multiple documents and applies 🔴/🟡/⚪ tags per the matter theory and side framing (plaintiff/defense/both).
  • Privilege gating and provenance: Enforces a privilege posture gate (A-cleared, B-mixed, C-aborted) and flags potentially privileged entries when needed.
  • Files the output in the matter workspace: Writes the working chronology to the matter directory and increments versions on rebuilds.

Frequently Asked Questions about chronology

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a litigation chronology from eDiscovery production files?

Build a litigation chronology by loading matter theory and document sources like PDFs, emails, and production exports. The system extracts dated events, de-duplicates them, and tags each by significance to create a working statement-of-facts timeline.

Can I generate a statement of facts timeline from Bates-stamped documents?

Generate a statement of facts timeline from Bates-stamped documents by running documents-mode extraction. It processes production exports, attributes every extracted event to retrievable sources with Bates citations, and flags potentially privileged entries.

How does de-duplication work when extracting events from multiple litigation documents?

De-duplication merges repeated events found across multiple document sources into single entries. It prevents redundant timeline entries by consolidating overlapping facts and applying significance tags based on the loaded matter theory.

Does this litigation timeline tool enforce privilege protections during document extraction?

It enforces a privilege posture gate during document extraction, classifying outputs as A-cleared, B-mixed, or C-aborted. This gate flags potentially privileged entries before writing the versioned chronology to the matter workspace.

What file formats work with litigation chronology extraction?

Litigation chronology extraction works with PDFs, emails, DOCX, TXT files, and connector-accessible archives. It reads these document sources to extract dated events and attributes them to the originating production files.

How do I tag events by significance when drafting a defense or plaintiff timeline?

Tag events by significance by loading your matter theory and side framing. The system automatically applies red, yellow, or white significance tags to extracted events based on their relevance to the plaintiff, defense, or both.
