Poly-hierarchical Metadata for Digital Archive Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital object description methods, such as the Dublin Core schema, are limited in providing broad or granular metadata, leading to inadequate digital object representation and distribution, especially in semantic marketplaces where detailed semantic representations are crucial for efficient search and retrieval.
Innovation Solution
A multi-schematic and multi-layered approach to metadata management using ontologies, thesauri, and controlled vocabularies to create poly-hierarchical semantic representations of digital objects, enabling the creation of three semantic versions of each object for enhanced search engine optimization and marketing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standardized schema like Dublin Core is used to describe digital objects, then the description adheres to a generally accepted standard, but the description becomes limited and cannot provide very broad or very granular detailed metadata
Solution Approach 1:
The patent segments metadata description into multiple hierarchical levels: a standardized upper level (Dublin Core) for broad compliance, and granular lower levels for detailed specific information. This allows the system to maintain standard adherence while capturing comprehensive metadata details through layered segmentation.
Solution Approach 2:
The patent adds a vertical dimension to metadata description by creating a multi-layered hierarchy. Instead of a single flat schema, the system implements multiple levels of description depth, allowing users to navigate from standardized broad descriptions to granular detailed metadata, effectively adding a 'depth' dimension to the metadata structure.
2Measurement precision
If cataloging is performed by domain experts using a particular schema, then the description is accurate within that domain, but the description is limited by the cataloger's subjective perspective and domain scope
Solution Approach 1:
The patent creates a universal multi-layered metadata framework that can accommodate multiple domain perspectives simultaneously. The standardized upper level provides a common foundation that works across domains, while lower granular levels allow domain-specific experts to contribute their particular perspectives, making the system both universally applicable and adaptable to diverse domains.
Solution Approach 2:
The patent merges multiple cataloging perspectives by combining standardized schema compliance with domain-specific granular metadata. The system integrates the objective standardized framework with subjective domain expert descriptions, creating a composite representation that captures both universal and domain-specific accuracy.
3Ease of manufacture
If a single schema is used for cataloging digital objects, then the cataloging process is simple and limited in scope, but the digital object representation lacks the detailed semantic information needed for efficient search and retrieval
Solution Approach 1:
The patent segments the cataloging process into manageable hierarchical layers. The upper standardized layer provides simple, straightforward cataloging that maintains ease of manufacture, while the lower granular layers capture detailed semantic information. This segmentation allows the system to remain simple at the entry level while accumulating rich semantic data through structured layering.
Solution Approach 2:
The patent performs preliminary action by establishing a standardized framework first, then progressively adding granular semantic layers. This preliminary standardized structure provides a solid foundation that simplifies initial cataloging, while subsequent layers of detailed metadata are added systematically to enhance semantic representation without overwhelming the initial process.
