Current Status of the Work

The current implementation of the Manifest output uses predicates to test the validity of the values extracted from the notary response. However, these predicates are not used for filtering, resulting in the return of values that are not described by the predicates. This can lead to unnecessary data being returned, making it difficult to work with the Manifest output.

Understanding the Issue

To better understand the issue, let's consider an example. Suppose we have a predicate that describes an array containing a "TEST" string. In this case, all the following values (arrays) would be considered valid and returned entirely:

["TEST"]
["TEST", "OTHER"]
["TEST", "OTHER_1", ... "OTHER_N"]

As you can see, the current implementation returns all the values that are considered valid by the predicate, even if they contain additional data that is not described by the predicate.

Should We Use Predicates for Filtering?

One possible solution to this issue is to use predicates to enable value filtering. If we do this, all the values above would be reduced to ["TEST"], which is the value described by the predicate. This would ensure that only the relevant data is returned, making it easier to work with the Manifest output.

However, this approach also has its drawbacks. For example, it may lead to a loss of information, as the additional data in the arrays is not returned. Therefore, it is essential to carefully consider the trade-offs before deciding whether to use predicates for filtering.

Benefits of Using Predicates for Filtering

Using predicates for filtering can bring several benefits, including:

Improved data quality: By only returning the values described by the predicate, we can ensure that the data is accurate and relevant.
Reduced data size: Filtering out unnecessary data can reduce the size of the Manifest output, making it easier to work with.
Simplified data processing: With only the relevant data returned, data processing becomes simpler and more efficient.

Challenges of Using Predicates for Filtering

However, using predicates for filtering also has its challenges, including:

Loss of information: Filtering out additional data may lead to a loss of information, which can be critical in certain scenarios.
Complexity: Implementing predicates for filtering can add complexity to the code, making it harder to maintain and update.
Performance impact: Filtering data using predicates can impact performance, especially for large datasets.

Alternatives to Using Predicates for Filtering

If using predicates for filtering is not feasible, there are alternative approaches that can be considered, including:

Using a separate filtering mechanism: Instead of using predicates for filtering, we can implement a separate filtering mechanism that is specifically designed for this purpose.
Returning a subset of data: Instead of returning all the values described by the predicate, we can return a subset of the data that is relevant to the use case.
Providing additional metadata: We can provide additional metadata that indicates which values are relevant and which are not, making it easier for users to work with the data.

Conclusion

In conclusion, using predicates for filtering can bring several benefits, including improved data quality, reduced data size, and simplified data processing. However, it also has its challenges, including loss of information, complexity, and performance impact. Therefore, it is essential to carefully consider the trade-offs before deciding whether to use predicates for filtering. If using predicates is not feasible, alternative approaches can be considered, including using a separate filtering mechanism, returning a subset of data, or providing additional metadata.

Future Work

Future work on this issue should focus on:

Implementing predicates for filtering: If the decision is made to use predicates for filtering, the implementation should be carefully designed to minimize the loss of information and ensure that the data is accurate and relevant.
Evaluating alternative approaches: If using predicates is not feasible, alternative approaches should be evaluated to determine which one is the most suitable for the use case.
Providing additional metadata: Providing additional metadata can help users work with the data more efficiently, making it easier to identify which values are relevant and which are not.

Recommendations

Based on the analysis above, the following recommendations are made:

Use predicates for filtering: If the decision is made to use predicates for filtering, the implementation should be carefully designed to minimize the loss of information and ensure that the data is accurate and relevant.
Evaluate alternative approaches: If using predicates is not feasible, alternative approaches should be evaluated to determine which one is the most suitable for the use case.
