PIDEX

Turn P&IDs and engineering records into trustworthy process context.

PIDEX reads a SmartPlant P&ID project read-only and emits engineering artifacts that engineers and AI agents can inspect, review, and publish from the same evidence.

Alpha / Evaluation

Currently in Alpha evaluation.

Problem

P&IDs are readable, but machines do not share the same identities and connections.

Drawings, tags, and lists can exist apart from shared identity, connectivity, and provenance. Filling gaps with filenames or on-screen proximity creates topology without authority.

What it does

Builds trustworthy engineering records and a process graph.

PIDEX collects Oracle schemas and drawing geometry from Smart P&ID read-only, then emits observed drawing evidence, DEXPI-based semantic artifacts, Engineering Identity / Rich Tag Graph, and lists into a result folder. Missing values stay missing; they are never guessed.

  • Input: SmartPlant P&ID project (read-only)
  • Output: Evidence SVG, DEXPI 2.0 XML, Engineering Identity / Rich Tag Graph, engineering lists
  • Work surfaces: Result Explorer, Workspace, CRS (review/comment), Engineering Publication

I/O flow

From source to publication

Authoritative sources create facts; evidence artifacts carry them; Workspace only gathers work context. Final publication authority stays with Engineering Publication.

Capabilities

What the product actually covers

Evidence SVG

One SVG per drawing with observed geometry, provenance and generation metadata, and embedded semantic data. Traceable drawing evidence — not a screenshot.

DEXPI 2.0 XML

Project and per-drawing DEXPI 2.0 XML with DEXPI-aligned vocabulary for semantic/process evidence. Normalization and exchange only — not DEXPI certified or compliant claims.

Engineering Identity / Rich Tag Graph

Exact engineering identities and source-backed relations. Topology authority lives here. TAG strings, SVG proximity, and viewer heuristics do not create topology.

Engineering lists · Result Explorer

Browse list outputs and the result folder’s drawings, records, data, and review tools. Engineering Graph visualization is a derived view of the Rich Tag Graph.

Workspace · CRS

Workspace is drawing- and object-centred work context. CRS binds comments, annotations, and identity links to a generation. It has no approval, e-signature, or publication authority.

Engineering Publication

The sole final publication authority for project PDF/A-4f with associated files. Workspace and CRS do not emit per-drawing or per-comment final PDFs.

Relation to Engineering Context

The primary Process Context product.

Engineering Identity and the Process Rich Tag Graph from PIDEX supply the process-side authority Tag Resolver uses with 3D model context. Spatial meaning belongs to S3DX’s Spatial Graph; PIDEX does not redefine it.

Workflow

Typical evaluation-host path

  1. 01

    Configure the Smart P&ID Oracle connection in setup (read-only).

  2. 02

    Select drawings, run generation/publication, and produce a result folder.

  3. 03

    Inspect Evidence SVG, DEXPI, Graph, lists, and verification/history in Result Explorer.

  4. 04

    Gather drawing/object context in Workspace; use CRS for comments and annotations when needed.

  5. 05

    Publish the project PDF/A-4f through Engineering Publication.

Boundaries and authority

What holds authority — and what does not

PIDEX never edits the source Smart P&ID project. Topology authority is the Rich Tag Graph; semantic/process evidence is DEXPI XML; final publication is Engineering Publication only.

Layer Role
Rich Tag Graph / Engineering Identity Topology and engineering-identity authority
DEXPI 2.0 XML Semantic/process evidence (normalize/exchange). No certified/compliant claim
Evidence SVG / Drawing Evidence Observed drawing and geometry evidence
Engineering Graph visualization Derived view only — not authority
Workspace Task/context only — not engineering authority
CRS Review/comment/annotation workflow — no approval or e-signature
Engineering Publication Sole final publication authority (PDF/A-4f)
Engineering Record Provenance, integrity, generation, currentness — not approval
  • No topology from TAG-string matching, SVG proximity, or viewer heuristics.
  • Missing model values are reported as missing — never guessed.
  • No DEXPI certified or DEXPI compliant claims.
  • No promise of fully automatic P&ID recognition or 100% accuracy.
