1. constants (0% yield — not yet implemented)
Named values with units that remain fixed within a standard or design context.
Detection heuristics: Named value with "=" sign, units in parentheses or brackets, appears in tables or definition lists, often prefixed with a symbol (Greek or Latin letter).
Key extraction fields:
| Field | Description |
|---|---|
name |
Human-readable name |
symbol |
Mathematical symbol (e.g. f_ci, ρ) |
value |
Numeric value |
units |
SI or field units |
source_standard |
Standard reference (e.g. DNV-RP-B401 Sec 3.4) |
2. equations (0% yield — not yet implemented)
Mathematical relationships between variables.
Detection heuristics: Contains mathematical notation, Greek letters, operator symbols (=, ×, /, ^), variable definitions follow the expression, often numbered (Eq. 1, Equation 3.2).
Key extraction fields:
| Field | Description |
|---|---|
name |
Equation name or number |
expression |
Mathematical expression (LaTeX or plain text) |
variables |
List of {symbol, name, units} |
source |
Standard and section reference |
applicability |
Conditions where equation applies |
3. tables
Tabular data — lookup values, design parameters, or comparison matrices.
Detection heuristics: Grid or tabular layout, header row with column labels, numeric cells with units, often titled "Table N" or has a caption.
Key extraction fields:
| Field | Description |
|---|---|
title |
Table caption or identifier |
columns |
List of column headers with units |
rows |
Data rows as lists or dicts |
interpolation_method |
Linear, step, or none |
source |
Standard and table number |
4. curves
Graphical data — x-y relationships presented as figures.
Detection heuristics: Figure references ("Figure N", "Fig."), x-y axis labels, data series legends, often accompanied by a caption describing the relationship.
Key extraction fields:
| Field | Description |
|---|---|
title |
Figure caption |
x_axis |
{label, units, range} |
y_axis |
{label, units, range} |
data_points |
Digitized x-y pairs |
source |
Standard and figure number |
5. procedures (0% yield — not yet implemented)
Sequential steps for performing an operation or assessment.
Detection heuristics: Numbered or lettered steps with sequential dependencies,
prerequisites section, action-oriented language. The distinguishing feature vs
requirements is sequential execution order — procedures describe how to do
something step-by-step, requirements state what must be true.
Disambiguation rule: If a clause contains both normative language ("shall")
and sequential steps, classify as procedures when the steps have execution
order, or requirements when each statement stands independently. Multi-label
output is allowed when both types genuinely co-exist in the same passage.
Key extraction fields:
| Field | Description |
|---|---|
title |
Procedure name |
steps |
Ordered list of step descriptions |
prerequisites |
Required inputs or conditions |
standard_ref |
Source standard and section |
decision_points |
Steps with branching logic |
6. requirements
Normative statements that define mandatory or recommended practice.
Detection heuristics: Contains "shall", "required", "must", "is to be"; often numbered with a requirement ID; may reference verification methods.
Key extraction fields:
| Field | Description |
|---|---|
id |
Requirement identifier |
text |
Full requirement statement |
standard_ref |
Source standard and clause |
verification_method |
How compliance is verified |
normative_strength |
shall / should / may |
7. definitions
Terms and their meanings as used within a standard or domain.
Detection heuristics: "means", "is defined as", "refers to"; glossary or definitions section; term followed by colon or em-dash and explanation.
Key extraction fields:
| Field | Description |
|---|---|
term |
The defined term |
definition |
Full definition text |

8. worked_examples (0% yield — not yet implemented)
Step-by-step calculations demonstrating application of equations or procedures.
Detection heuristics: "Example", "Sample calculation"; given/find/solution pattern; specific numeric values substituted into equations; final answer with units.
Key extraction fields:
| Field | Description |
|---|---|
