Abstract: A method for operating a product configuration service, wherein the method comprises: receiving a query pertaining to a scope of searching for a configuration of a product; retrieving, based on the query, information from a self-referencing data model that stores the information as items having item types, wherein the information comprises: variables associated with an entity and values for the variables defined by files of the entity, wherein variables are defined by features that are linked to a source of the files, rules that specify compatibility constraints between the variables, and the information is used during runtime and not persisted to memory; generating, based on the rules and the variables, a solution space comprising the values; and presenting the solution space in a user interface of a computing device of a user.

Abstract: A method for performing recursive searching of items of a data structure having a data mode includes creating an instance of a query definition, the instance of the query definition comprising a unique identifier, specifying one or more elements of the query definition, providing the query definition as an input to a query engine. The method further includes the operations of determining, by the query engine, query execution instructions based on the query definition, the query instructions specifying a recursive level-by-level search until a terminal node of the data structure is reached, obtaining results of a query executed based on the query execution instructions; and outputting query results.

Abstract: In one embodiment, a method is disclosed. The method may include applying a mandatory access control (MAC) policy to an item type, and receiving, from a processing device, a request to access a first item in a data structure, wherein the first item including the item type, responsive to receiving the request. The method may include executing the MAC policy to instruct the processing device to traverse one or more relationships between the first item and one or more other items to identify a target item, determining whether a derived attribute of the target item is satisfied. Responsive to determining the derived attribute of the target item is satisfied, the method may include enabling access to the first item.

Abstract: A method for implementing access controls for items of data belonging to a self-describing data structure including obtaining a query definition specifying a requested item of data in the self-describing data structure, determining domains associated with the requested item, the domains including a set of items within the self-describing data structure on an execution path of a query executed according to the query definition. For each respective domain associated with the requested item, the method includes determining subdomains associated with the requested item, determining a role of the user for the respective domain, the role is associated with a set of access permissions to items of data within the domain, and generating an output corresponding to whether access to the requested item is granted based on a policy for each of the subdomains associated with the requested item and the role of the user for the domain.
