Platform management of integrated access of public and privately-accessible datasets utilizing federated query generation and query schema rewriting optimization

A non-transitory computer readable medium having one or more computer program instructions configured to perform a method, the method comprising:

• receiving a query at a dataset access platform, the query being formatted according to a first data schema including a structured relational-based format, the query comprising data associated with a request to access a dataset;
• generating a copy of the query, the copy being identified as a master and configured to be stored in a datastore;
• parsing the copy of the query in the first schema, the parsing being performed by an inference engine configured to identify the dataset, to infer an attribute associated with the query, and to generate one or more data links between the dataset and another dataset accessible by the dataset access platform;
• rewriting, using a proxy server, the copy of the query in a second schema including a triples-based format and, if the attribute indicates the query is configured to provide authentication data to access the dataset, the rewriting comprising converting the copy of the query into a triple and converting the attribute into another triple;
• and
• optimizing the rewriting, the optimizing comprising identifying a database engine to execute the query and converting other data to a further triple, the other data and the further triple being associated with a path configured to route the query or the copy of the query in the second schema including the triples-based format from the dataset access platform to retrieve query results from a target database configured to store the dataset as graph-based data.
