System and method for querying a data repository

A system comprising:

• one or more processors;
• a memory storing instructions that, when executed by the one or more processors, cause the system to perform a method comprising:
• receiving, by a computing system, one or more terms with which to search a plurality of datasets;
• identifying, by the computing system, datasets in the plurality of datasets that are related to the one or more terms based on ontologies associated with the datasets, wherein the identifying of the datasets comprises identifying a first dataset related to a first term of the one or more terms, identifying a second dataset related to a second term of the one or more terms, and identifying a third dataset related to a third term;
• accessing, by the computing system, templates, wherein the templates indicate an ordering of slots to be populated with a sequence of keywords that match properties corresponding to the slots, wherein the templates are based on relationships within the ontologies, wherein the ontologies comprise or are represented as an object graph in a separate metadata layer;
• generating, by the computing system, based on the templates, one or more search queries that correspond to the one or more terms based on the datasets and the ontologies, wherein generating one or more search queries comprises:
• determining any relationship between the first dataset and the second dataset;
• generating the one or more search queries based on the relationship;
• determining any updated relationship between the first dataset, the second dataset, and the third dataset, wherein the any updated relationship is based on a relationship between the one or more search queries and the third term;
• and
• generating the one or more search queries based on the any updated relationship;
• receiving, by the computing system, a selection of a particular query from the one or more search queries;
• generating, by the computing system, based on the particular query, logic to transform the particular query into an executable query;
• transforming, according to the logic, the particular query into the executable query;
• and
• returning one or more results from the plurality of datasets based on the particular query.
