Abstract: Embodiments of the present invention provide methods, systems, and/or the like for versioning a graph representation in a graph data structure. In accordance with one embodiment, a method is provided comprising: conducting a plurality of iterations involving: validating a first data source comprising a new version of data based on a schema from a plurality of schemas in which each schema corresponds to a graph representation found in a graph data structure; and identifying errors in the first source based on the validating of the source; identifying an applicable schema as a schema producing fewer errors than at least one other schema; comparing the first source with a second source comprising a previous version of the data to identify a difference; generating a query for the difference based on the applicable schema; and providing the query for execution to migrate the difference into the graph representation.
