Matching metastructure for data modeling

A method for maintaining data model mappings, the method comprising:

• receiving a first data model comprising one or more structural components and one or more relationships between structural components;
• generating a first data schema for the first data model, the first data schema comprising:
• a set of schema objects corresponding to the one or more structural components of the first data model, wherein a given schema object comprises a schema object identifier and a structural component identifier;
• and
• a set of relationship objects corresponding to the one or more relationships in the first data model, wherein a given relationship object comprises a relationship object identifier, a first schema object identifier, and a second schema object identifier;
• receiving a second data model comprising one or more second structural components and one or more second relationships between second structural components;
• generating a second data schema for the second data model, the second data schema comprising:
• a second set of schema objects corresponding to the one or more second structural components of the second data model, wherein a given second schema object comprises a second schema object identifier and a second structural component identifier;
• and
• a second set of relationship objects corresponding to the one or more second relationships in the second data model, wherein a given second relationship object comprises a second relationship object identifier, a third schema object identifier, and a fourth schema object identifier;
• receiving one or more mappings between the first data model and the second data model;
• and
• generating a data schema alignment for the first data model and the second data model, the data schema alignment comprising:
• a set of alignment mappings based on the one or more received mappings, wherein a given alignment mapping comprises identifiers for one or more schema objects from the first data model and an identifier for a schema object in the second data model.

A method, implemented by one or more computing devices comprising at least one hardware processor and one or more tangible memories coupled to the at least one hardware processor, for generating a metadata representation of a first data model, the method comprising:

• receiving a source representation of the first data model, wherein the source representation comprises a representation of one or more structural components of the first data model, respectively having identifiers and types;
• generating a one or more instances of a metastructure schema object datatype based on the one or more structural components of the source representation, the metastructure schema object datatype comprising a first data member representing an identifier for a structural component represented by an instance of the metastructure schema object datatype and a second data member representing a structural component type for a structural component represented by an instance of the metastructure schema object datatype, wherein generating a given instance of the metastructure schema object datatype for a given structural component comprises:
• assigning a first identifier of the given structural component to the first data member of the given instance;
• determining a first type associated with the given structural component;
• and
• assigning the first type to the second data member of the given instance;
• and
• storing the one or more instances of the metastructure schema object datatype in association.
