Platform · Line Lists

Upload a line list. Get structured, reconciled line data.

Armeta parses engineering line lists — whether PDF tables, Excel exports, or scanned tabular documents — into structured line-level records: line numbers, sizes, material specs, insulation, design and operating conditions, from-to connectivity, and P&ID references. Line list data is contextualized against P&ID and isometric data to surface discrepancies and build the complete engineering knowledge graph.

What Armeta extracts

Every column, every row, every attribute.

The line list is the structured complement to the graphical record. Armeta preserves your schema and parses each column into queryable fields — including the columns that are usually flattened into free text.

Line number

Parsed using your numbering convention. Service codes, size, material class, area, and sequential identifier separated into structured fields.

Nominal diameter

Captured per row with units normalized — inches, millimeters, mixed-unit imports — so the structured output is queryable across vintages.

Pipe spec / material class

Material class assigned per line (e.g. A1A, B2B) extracted and resolved against your pipe specification register.

Insulation

Insulation type and thickness captured where present, including heat-tracing notes flagged as separate structured attributes.

Design pressure & temperature

Captured separately from operating values so any downstream stress, integrity, or compliance workflow has the right column to read.

Operating pressure & temperature

Operating-condition columns parsed and reconciled against the design columns and the source P&ID where applicable.

Fluid service

Service classification (hydrocarbon, hydrogen, sour, utility, etc.) captured per line and used for downstream regulatory tagging.

From-to connectivity

Origin and destination equipment tags or off-page references parsed into a structured connectivity column ready for graph assembly.

P&ID reference

Source P&ID drawing number per line — the join key used to reconcile the line list against the rest of the engineering archive.

Remarks & special notes

Heat tracing, slope requirements, NDT flags, and other free-text remarks structured as discrete tags rather than dropped on the floor.

Cross-document reconciliation

The line list as the reconciliation layer.

A line that exists on a P&ID should appear on the line list. A line on the line list should have a corresponding isometric. Discrepancies between these three sources almost always indicate either a documentation error or an undocumented field modification — both of which matter.

Armeta runs the reconciliation automatically and surfaces the disagreements as structured reports for engineering review.

Stage 01

Line-number entity resolution

Every row, an addressable entity in the graph.

Each line-list row is parsed against your numbering convention and promoted to a first-class entity. Soft variants (formatting, leading zeros, hyphens) are normalized; hard mismatches are flagged for review rather than silently merged.

Stage 02

P&ID-to-line-list match

Schematic and tabular records, joined on identity.

Every line on the line list is matched to its appearance on the P&ID. A line on the list with no P&ID presence is surfaced. A line on the P&ID with no list entry is surfaced. The two sources cross-validate each other rather than living in parallel.

Stage 03

Isometric verification

Spatial reality, reconciled against the data table.

Where isometrics exist, the line list is reconciled against the spatial record. Spec, size, and service are cross-checked spool by spool so the line list reflects what was actually fabricated and installed.

Stage 04

Discrepancy surfacing

Disagreements made visible, not papered over.

Where the P&ID, isometric, and line list disagree, Armeta produces a structured discrepancy report with both values and their source documents. Reconciliation is a decision your engineering team makes with full evidence, not a guess the model makes for you.

Workflows enabled

What structured line list data unlocks.

Once the line list is structured and reconciled against the graphical record, the workflows that depend on it stop being spreadsheet archaeology.

Format handling

The line lists your archive actually contains.

Real-world line lists come in every format engineering data has ever lived in: native Excel exports with merged headers, PDF tables with image-baked text, and scanned tabular documents from filing cabinets. Armeta reads them all.

No re-keying. No template forcing. Your line-list schema is what comes out the other side — cleanly structured and joined to the rest of the engineering knowledge graph.

Accuracy and validation

Accuracy you can put in a contract.

Every parsed line list Armeta delivers is validated against the source document by our engineering team before it reaches you. Accuracy metrics on your own line lists are produced as part of the initial document audit — our ten-document free assessment that establishes baseline performance before any paid engagement.

Engineer-reviewed parsing

Every parsed line list is reviewed by an Armeta engineer against the source document before delivery. Not raw model output.

Source-cell traceability

Every structured field links back to the exact cell or region on the source line list — auditable, click-through, defensible.

Cross-document discrepancy reports

Differences between the line list, the P&ID, and the isometric are surfaced as structured reports so engineering reconciles them with full evidence.

Schema fidelity

Your line-list schema is preserved. Columns are not dropped, not renamed, and not silently merged — the structured output round-trips cleanly back to your master.

Deployment

Your line lists. Your environment. Your terms.

Three deployment modes, chosen to match the security and governance constraints your engineering records actually live under.

Mode 01

Cloud

Fastest time to value

Armeta-hosted, isolated per customer. Your engineering documents and extracted data remain segregated from every other customer environment.

  • Isolated tenant per customer
  • Data residency US, EU, or customer-designated region
  • Production-ready in days, not months
Mode 02

On-premise

Your network, your perimeter

Armeta's contextualization engine runs inside your network. Your documents never leave your environment. Deployed with customers today under data residency and air-gap requirements.

  • Documents never leave the customer network
  • Air-gap-compatible deployment
  • Suitable for classified processes and strict residency policies
Mode 03

Private cloud

Managed inside your tenant

Armeta-managed deployment inside your own cloud tenant. Cloud operational model, customer-controlled perimeter.

  • Customer-controlled cloud perimeter
  • Managed service lifecycle
  • Fits existing cloud governance frameworks
Your line lists, your data

Start with ten of your own line lists.

Before any procurement conversation, see Armeta run on your actual line lists — structured row by row and reconciled against your P&IDs and isometrics. Not sample data. Not a generic demo. Your line lists, contextualized, delivered as a structured report in one engagement.
