Arianna 2.0
Every great industrial project begins with an idea. But it takes shape through thousands of documents.
Arianna 2.0 is a multi-user document management system built for plant engineering — a controlled home for every drawing, specification and revision a project produces, from first issue to final handover.
The problem it solves
On a live project, documents multiply faster than anyone can track them: revisions circulate by e-mail, folders fork into “final” and “final_2”, and sooner or later someone builds from a superseded P&ID. The error surfaces on site — where it costs the most.
One principle above all
Originals are never modified and never silently overwritten. Every change enters the archive as a new revision, and every revision stays traceable — forever. The name is no accident: like Ariadne's thread, Arianna leads safely through the labyrinth of project documentation.
A place for everything
A six-level hierarchy gives every document exactly one home — from the client at the root down to the single file of a single revision, with an optional plant/unit level for multi-skid projects. No duplicates, no orphans, no parallel truths.
- Client
- Project
- Plant / Unit
- Document type
- Revision
- File
From draft to issued
Every file moves through a six-status approval cycle that mirrors how plant documentation is really validated. The colored badge on the tree tells the story without opening the file.
- Draft
- Internal review
- Client review
- Approved
- Issued
- Archived
What it does
-
Controlled vault
Check-out / check-in with exclusive locking: a working copy on your disk (editable offline), the official file untouched until a verified check-in — and only you can check it back in.
-
Revisions with responsibility
Every new revision requires a reason and records who prepared, checked and approved it. Identical files are caught by SHA-256 before they become pointless revisions.
-
Search everywhere
Quick-open search (Ctrl+K): file name, code, title or tag — results in real time, across every client and project.
-
Dependency map
FEEDS / IMPACTS relationships between document types — defined once, reused in every project, from process narrative to as-built. See what a change touches before it reaches the site.
-
Full traceability
Immutable audit trail, project timeline and evolution report ready to paste into a client e-mail, and a KPI dashboard with live counts per workflow status.
-
Multi-user by design
Five predefined roles — from Administrator to Viewer — with per-permission fine-tuning, for a whole team on one shared archive.
Technical foundations
- PostgreSQL database — one shared source of truth; physical files live outside the database, in managed, secure storage.
- SHA-256 fingerprint on every file — integrity verified, duplicates caught automatically.
- Desktop application, multi-user over the local network — your documents never leave the company.
- Multi-site synchronization — a sync queue propagates every operation across connected sites, tolerant of working offline.
- Modular by installation — three predefined profiles (Base, Engineering, Enterprise) or a custom combination; the Core module is always active.
- Fully localized interface — Italian and English, switchable at any time.
