+# Metaproteomics results data should not be in Mongo
+## Context and Problem Statement
+
+There are large mongo data records for metaproteomics workflow activities, this causes issues for the API and elsewhere and is not sustainable. 
+
+
+## Considered Options
+
+* **Rework Aggregation Scripts**
+
+Rewrite the aggregation scripts to access the Metaproteomics processed data (not just the mongo records about those data).
+
+* **Bypass Aggregation Scripts**
+
+Modify the Metaproteomics workflow to directly write the FunctionalAnnotationAggMember records (originally written by aggregation script).
+
+
+## Decision Outcome
+
+Chosen option: "**Rework Aggregation Scripts**", to maintain modularity of the aggregation process.
+
+We will also rewrite the aggregation script to use the API rather than directly access mongoDB.
