48-50: Security concern: Accepting unverified credentials without proper verificationAccepting unverified credentials when the issuer matches the sender can introduce security vulnerabilities. Relying solely on the transaction's signature may allow malicious actors to submit fraudulent credentials without proper validation. It is recommended to enforce full credential verification even when the issuer matches the sender to ensure the integrity of the data.

8-41: Consider enhancing error handling and documentation.While the code is well-structured, consider these improvements:
- Replace generic
StdResultwith custom error types for more specific error handling- Add documentation comments explaining the purpose and behavior of each function
Example implementation:
/// Custom error type for mapping operations #[derive(Debug, thiserror::Error)] pub enum MapperError { #[error("Failed to resolve namespace: {0}")] NamespaceResolution(String), #[error("Invalid IRI format: {0}")] InvalidIRI(String), } /// Converts a Literal to an Object, resolving any typed values using the provided namespace solver /// /// # Arguments /// * `ns_solver` - Namespace resolver implementation /// * `prefixes` - Map of prefix to namespace mappings /// * `literal` - The literal value to convert /// /// # Returns /// * `Result<Object, MapperError>` - The converted object or an error pub fn literal_as_object( ns_solver: &mut dyn NamespaceSolver, prefixes: &HashMap<String, String>, literal: Literal, ) -> Result<Object, MapperError> { // ... existing implementation ... }contracts/axone-cognitarium/src/contract.rs (2)

888-1084: Consider improving test maintainabilityThe test cases contain repetitive template construction code. Consider introducing helper functions to reduce duplication and improve maintainability.
Example refactor:
fn create_delete_template(subject: &str, predicate: &str, object: &str) -> parser::TripleDeleteTemplate { parser::TripleDeleteTemplate { subject: VarOrNamedNode::NamedNode(Full(subject.to_string())), predicate: VarOrNamedNode::NamedNode(Full(predicate.to_string())), object: VarOrNamedNodeOrLiteral::NamedNode(Full(object.to_string())), } } // Usage in tests let template = create_delete_template( "https://ontology.axone.space/dataverse/dataspace/metadata/unknown", "https://ontology.axone.space/core/hasTopic", "https://ontology.axone.space/thesaurus/topic/Test" );

2285-2340: Enhance code clarity in construct templatesWhile the functionality is correct, consider these improvements for better readability:
- Use more descriptive variable names (e.g.,
temporal_coverageinstead oftcov)- Consider breaking down long template definitions into smaller, well-named components
Example refactor:
// Define template components with descriptive names let temporal_coverage_template = parser::TripleConstructTemplate { subject: VarOrNode::Node(BlankNode("metadata".to_string())), predicate: VarOrNamedNode::NamedNode(Full( "https://my-ns/predicate/temporal-coverage".to_string(), )), object: VarOrNodeOrLiteral::Variable("temporal_coverage".to_string()), }; // Use components in test cases let templates = vec![ temporal_coverage_template, information_template, // ... other templates ];

1-1: LGTM! The import change aligns with the architectural refactoring.
The modification to import Literal and IRI from parser instead of msg reflects a cleaner separation of concerns, moving parsing-related types to a dedicated module.
Let's verify the consistency of this change across the codebase:
✅ Verification successful
Import changes are consistent across the codebase
The verification confirms that:
- No remaining imports of
LiteralorIRIfrom themsgmodule exist - All imports of these types now consistently use the
parsermodule across four files:contract.rsvariable.rsplan_builder.rsmapper.rs
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify that all imports of Literal and IRI are now from the parser module
# Check for any remaining imports from msg module
echo "Checking for any remaining imports from msg module..."
rg "use crate::msg::(.*)(Literal|IRI)" -g "*.rs"
# Verify new imports are consistent
echo "Verifying new imports from parser module..."
rg "use crate::parser::(.*)(Literal|IRI)" -g "*.rs"

107-109: LGTM! Term methods are well-implemented.
The from_iri and from_literal methods properly handle all cases with appropriate error handling. The test coverage is comprehensive and validates the behavior thoroughly.
Also applies to: 112-123
390-398: LGTM! IRI test cases are comprehensive.

1-3: Imports updated to reflect module refactoring
The import statements correctly reference types from crate::parser, aligning with the reorganization of query-related types.
contracts/axone-cognitarium/src/lib.rs (1)
4-4: Addition of parser module enhances modularity
Introducing the parser module improves code organization by separating parsing functionalities from message definitions.
contracts/axone-cognitarium/src/querier/plan_builder.rs (6)
1-4: Imports adjusted for module restructuring
The import statements now correctly source types from crate::parser, ensuring consistency with the refactored codebase.
121-162: Function build_expression correctly utilizes parser::Expression
The build_expression function has been appropriately updated to pattern-match on parser::Expression variants, maintaining functionality after the refactoring.
288-288: Test module imports updated appropriately
The test module now imports Literal, Node, Prefix, and IRI from crate::parser, ensuring that tests align with the updated module structure.
671-754: Test cases updated to use new parser::Expression variants
The test cases have been adjusted to utilize parser::Expression variants, ensuring they effectively test the refactored build_expression function.
915-915: Filter expression correctly handles bound variables
In the build_plan test case, the filter expression uses variable "1", which is bound in the inner WhereClause. This ensures proper evaluation during query execution.
943-943:
Unbound variable detected in filter expression
The filter expression uses variable "oups", which is not bound in the inner WhereClause. This will result in an error due to the unbound variable.
Please verify that all variables used in filter expressions are properly bound in the query plan to prevent runtime errors.

The test coverage has decreased due to the calculation method, as some files were moved without their associated tests. However, the actual coverage remains unchanged. |
Let’s move the types used to query the
cognitariuminto a dedicatedastfile. Their structure already hints at an AST-like representation of the query grammar. This sets the stage for what’s coming next… Stay tuned. 👀Summary by CodeRabbit
