Case Notes & Documentation: Investigation Recording

Overview#

An investigator conducts a two-hour witness interview in the morning, then takes a statement from a second witness at a different location in the afternoon. By the time she returns to the office, she needs both records logged against the correct case, timestamped, attributed to her account, and available to her supervisor for review. Case Notes & Documentation makes that a routine end-of-day task rather than an administrative burden.

The module provides professional note-taking and documentation tools designed for high-stakes investigations requiring detailed record-keeping, legal defensibility, and seamless team collaboration. It transforms fragmented note-taking across disparate tools into comprehensive, searchable, and version-controlled documentation that supports both daily investigative work and formal legal proceedings.

Key Features#

• Rich Text Editing: Full-featured text editor with formatting, tables, lists, inline images, embedded media, and custom styles for creating detailed, professional investigation notes
• Investigation Templates: Pre-built note templates for common activities including interviews, field observations, evidence collection, case summaries, and witness statements, ensuring consistent documentation standards
• Real-Time Auto-Save: Automatic saving ensures no work is lost, with continuous background synchronisation across devices and protection against browser crashes or connection interruptions
• Version History: Complete history of every edit with the ability to view, compare side-by-side, and restore any previous version of a note with full attribution of who made each change
• Full-Text Search: Instantly search across all notes by content, author, date, case, tags, or custom metadata fields to find relevant information within large documentation libraries
• Collaborative Editing: Multiple team members can contribute to shared notes simultaneously with attribution, change tracking, commenting, and review workflows
• Secure Access Controls: Role-based permissions ensure sensitive notes are only visible to authorised team members, with full access logging for compliance and audit purposes
• Offline Capability: Create and edit notes without an internet connection, with automatic synchronisation when connectivity is restored and conflict resolution for concurrent edits
• Note Linking: Link notes to specific evidence items, case entities, and other notes to create a connected web of investigative documentation
• Audio and Image Attachments: Attach audio recordings, photographs, and other media directly to notes for comprehensive documentation of investigative activities

Use Cases#

Field Investigation Documentation#

Investigators capture observations, witness statements, and evidence details in the field using mobile devices, with notes automatically syncing to the central case file when connectivity is available. Templates ensure all required information is captured consistently.

Interview Recording#

Interviewers use structured templates to document interview sessions with consistent formatting, ensuring all required information is captured and properly attributed for legal proceedings. Audio recordings can be attached alongside written summaries.

Collaborative Case Summaries#

Investigation teams collaboratively build case summaries by contributing findings from different investigative threads. Version control ensures a coherent and complete final document, and comments enable review and feedback without modifying the main content.

Legal Review Preparation#

Legal teams review investigation notes with complete version history and audit trails, preparing documentation packages that meet evidentiary standards for court proceedings. The integrity of the note record supports admissibility.

Knowledge Preservation#

Detailed documentation of investigative methods, findings, and lessons learned preserves institutional knowledge for future reference, training materials, and precedent analysis across the organisation.

Workflows#

Note Creation and Collaboration#

1. Select a note template or create a blank note within a case workspace
2. Compose the note using the rich text editor with formatting, media, and structured sections
3. Add tags, link to evidence items and entities, and assign access permissions
4. Share with team members for collaborative review, contribution, and feedback
5. Finalise the note through the review workflow if required for the case type

Note Search and Retrieval#

1. Enter search terms, filters, or tags in the search interface
2. Results are returned with highlighted matches, contextual previews, and relevance ranking
3. Open notes directly from search results with full editing or view-only capability based on permissions
4. Save frequent searches as bookmarks for quick access to commonly needed documentation

Version Review#

1. Open a note and access the version history panel
2. Select two versions to compare side-by-side with change highlights
3. Review the changes made between versions with author attribution
4. Restore a previous version if needed, with the restoration recorded in the version history

Integration#

• Programmable API Access: Create, retrieve, and manage notes programmatically for integration with external documentation and case management systems
• Document Management Systems: Link notes with enterprise document repositories for centralised storage, retrieval, and archival
• Communication Platforms: Share notes and receive notifications through email, messaging, and collaboration tool integrations
• Export Formats: Export notes to PDF, Word, and other standard formats for external sharing, legal production, and archival requirements

Open Standards#

• GraphQL (June 2018 specification): All note and annotation operations are exposed through a GraphQL API, enabling structured queries, mutations, and type-safe access for external integrations and the web client.
• ISO 8601 (date and time): All note creation, update, and access timestamps are stored as timezone-aware UTC datetimes in strict ISO 8601 format, ensuring unambiguous chronological ordering for legal and audit purposes.
• SHA-256 (FIPS 180-4): Attached document files are hashed with SHA-256 on upload and on each new version, providing a cryptographically verifiable checksum to support chain-of-custody and evidentiary integrity requirements.
• MIME types (RFC 2045 / RFC 2046): Attached and exported files are labelled with standard MIME media types (e.g. application/pdf, audio/mpeg, message/rfc822) to ensure interoperability with document management systems and legal review platforms.
• OAuth 2.0 / JWT (RFC 6749 / RFC 7519): Role-based access control on every note and annotation operation is enforced by validating JWT bearer tokens issued under the platform's OAuth 2.0 authorisation server, scoping read, write, and audit permissions per case.
• UUID (RFC 4122): Every note, annotation, tag, and document record is assigned a version-4 UUID as its primary identifier, guaranteeing collision-free references across distributed systems and exported document packages.
• CommonMark (Markdown): Notes support optional Markdown rendering via the CommonMark specification, allowing investigators to apply structured formatting, lists, and tables that render consistently in web views and exported reports.
