Field names

Use snake_case with the unit at the end:

Examples

Process data

  • reactor_temp_set_C — Target temperature
  • reactor_temp_C — Measured temperature
  • glucose_feed_vol_L — Volume of glucose added
  • filter_inlet_press_lim_bar — Pressure limit

Manufacturing & QC

  • housing_length_mm — Measured length
  • screw_torque_lim_Nm — Torque specification
  • leak_test_result — Pass/Fail observation

Clinical & patient data

  • patient_weight_kg — Body weight
  • sys_BP_mmHg — Vital sign (systolic blood pressure)
  • pain_score — Patient-reported outcome

Choosing a naming standard

External standards (Allotrope, CDISC, ISA-88)

These standards are optimized for data exchange between systems, not daily usage. They prioritize universal definitions over specific context. For example, an ontology defines “Temperature,” but your process needs to distinguish inlet_temp from outlet_temp. Using abstract codes (like AFO_0000123) strips away this context, making data analysis harder and increasing the risk of interpretation errors. Best practice: Use descriptive, functional names inside Seal for clarity and safety. If you need to export to external standards (Allotrope, CDISC, etc.), speak to your solutions consultant—Seal can set up the appropriate transformations for your workflows.

Templates

Example: BR_MAB_Upstream, SOP_Deviation_Handling See Template prefixes for the full list. Versioning is handled automatically by Seal—don’t add _v1 to names.

Instances

Naming depends on whether the entity is a process (happening in time), a resource (physical), or a document (static).

Process (time-based)

Resource (physical)

Document (static)

Tip: Don’t repeat the product or process name in the instance (e.g., MAB_Upstream_B-2024-001). That metadata comes from the Template.

Common mistakes

Spaces and special characters are supported — formulas use bracket notation: entity["Temperature (°C)"]. See Formulas for details. Legacy v1 automations also support snake_case dot notation (self.fields.reactor_temp_C).
