Client Interfaces for Package Content Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional package mechanisms in data processing systems lack effective strategies for handling object generation, interfacing, and enhancements, especially when dealing with multiple interfaces, modules, components, and services across development projects, leading to complexity and inflexibility.
Innovation Solution
The implementation of client interfaces that allow access to package content through access objects, enabling services to expose and access content from client packages, while using dependency control lists to manage access permissions and visibility across package hierarchies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional package mechanisms are used to structure software, then packages can hide content and provide basic access control, but the mechanism lacks flexibility for handling object generation, interfacing, and enhancements across multiple interfaces and services
Solution Approach 1:
The patent segments the package mechanism into multiple hierarchical levels (package level, interface level, object level) with distinct access control lists at each level. This allows fine-grained control over object generation, interfacing, and enhancements without requiring a complete redesign of the package mechanism, thus improving flexibility while managing complexity through structured division.
Solution Approach 2:
The patent adds a new dimension to the package mechanism by introducing interface-level access control lists that operate alongside package-level controls. This multi-dimensional approach enables independent management of access permissions for different interfaces and services, providing the needed flexibility for object generation and enhancements without linearly increasing overall system complexity.
2Ease of operation
If packages expose development objects through interfaces, then access to objects is enabled, but control over access permissions and visibility across package hierarchies is insufficient
Solution Approach 1:
The patent applies local quality by implementing access control lists at specific interface levels rather than uniformly across the entire package. Each interface can have its own access control list defining which development objects are accessible and under what conditions. This localized approach maintains ease of access for authorized users while providing reliable, fine-grained control over permissions and visibility in different parts of the package hierarchy.
Solution Approach 2:
The patent introduces access control lists as intermediary structures between packages and development objects. These intermediate control mechanisms mediate access requests by evaluating permissions defined in the access control lists before granting access to development objects. This intermediary layer enhances control reliability without directly impeding ease of operation for authorized access scenarios.
3Ease of manufacture
If nested packages are used to structure software components, then modularity is improved, but visibility and access control across nested hierarchies becomes more difficult to manage
Solution Approach 1:
The patent implements nested access control lists that mirror the nested package hierarchy. Each package level maintains its own access control list, and nested packages inherit or override permissions through their respective access control lists. This nested structure preserves modularity by allowing independent management of each package's visibility and access control while systematically managing the complexity through hierarchical inheritance and override mechanisms.

AI summary
A method and system for employing client interfaces for packages. In one embodiment, an access object associated with a service provided by a first package is located, where the service is seeking to access content residing at a second package. A client interface is then created at the second package using the access object. The client interface is used to provide access to the content by exposing the content to the service via the client interface.
