Speckle Automate Function: Data Validation in AEC

This repository provides a Speckle Automate function crafted specifically for the AEC industry, demonstrating the power of data validation using the specklepy SDK.

Our function showcases both loose and tight coupling methodologies between check rules (conditions we validate) and actions (responses based on conditions). This balance ensures adaptability and reliability in our validation framework.

How the Validation Works

In the AEC domain, data validation isn't merely about ensuring data integrity. It's about comprehending the intricate relationships between data points, especially when diving into BIM (Building Information Modelling). This function demonstrates the traversal through and manipulation of this complex web of relationships while preserving the integrity of the overall data structure.

Check Rules and Actions: The Core Framework

Our system's core is the dynamic relationship between check rules (conditions we validate against) and actions ( operations we conduct based on these conditions). This relationship can be:

• Loosely Coupled: In this method, checks and actions remain modular and distinct. This flexibility allows checks to be paired with diverse actions depending on specific needs.

• Tightly Coupled: Here, specific checks are intrinsically linked to distinct actions. This ensures a predictable validation trajectory.

Our function manifests both methods. While the ParameterRules class provides modular checks, the subclasses of ParameterAction, such as PrefixRemovalAction, embrace the tight coupling principle, offering specific responses to set conditions.

Traversal Rule Pattern: Navigating Complex Data Structures

The traversal methodology found in both the speckle-sharp and specklepy SDKs, which we refer to as the TraversalRule pattern, is integral to our validation process. Its utility is manifold:

1. Preserve Hierarchical Relationships: BIM data is all about hierarchy - a door hosted by a wall, situated in a room, and so on. Using the traversal methodology, while elements can be changed, their relationships with other elements stay intact.

2. In-place Data Mutation: Rather than spawning entirely new data structures, the traversal method champions in-place data mutation. This approach is not only efficient but also minimizes data loss risks.

3. Maintain Original Constructs: This becomes pivotal when examining elements like family instances in Revit. A single alteration can ripple through the data. The traversal methodology ensures that while data undergoes validation or changes, original structural relationships are upheld.

Zooming Out: The Broader Perspective

In the AEC landscape, data validation transcends data integrity; it's about safeguarding relationships and data hierarchies. With a robust blend of check rules, actions, and the traversal methodology, our function stands as a testament to handling intricate AEC data with finesse, balancing both data accuracy and structural authenticity.
