Derivative Disclosures

Axis 1: Material & Component Substitution

1.1. Neuromorphic Processing Implementation

• Enabling Description: An apparatus where the core logic is implemented on a neuromorphic processor (e.g., an Intel Loihi or IBM TrueNorth-style architecture) rather than a traditional von Neumann CPU. Information "data" chunks are stored in conventional memory, but the labels and their hierarchical relationships are encoded as a network of spiking neurons and synapses. A "label" is represented by a specific group of neurons that fire in a unique pattern. A "parent-child" relationship in the hierarchy is encoded as a strong synaptic connection from the parent neuron group to the child neuron group. Retrieving information involves stimulating the neuron group corresponding to a high-level label, which triggers a cascading spike pattern through the hierarchy, ultimately activating the pathway to the memory address of the associated data. User interaction for defining the structure involves a Hebbian learning process, where the user's navigational choices strengthen or weaken synaptic connections.

1.2. DNA & Quantum Archival System

• Enabling Description: A hybrid storage system for long-term archival. The raw information "data" (e.g., audio, video) is encoded into synthetic DNA strands for high-density, multi-millennium storage. The user-defined labels and hierarchical structure are encoded as quantum bits (qubits) in a small-scale quantum computer or a dedicated quantum memory register. The association between a label and its data is a mapping from the quantum state of the label to the DNA sequence primer required to initiate PCR amplification and sequencing of the correct data strand. Retrieval is a two-step process: a quantum search algorithm (e.g., Grover's algorithm) rapidly searches the label hierarchy in the quantum register, and the resulting quantum state provides the classical information (the primer sequence) needed to retrieve the data from the DNA archive.

Axis 2: Operational Parameter Expansion

2.1. Industrial-Scale Digital Twin Labeling

• Enabling Description: A system applied to the management of a large-scale industrial facility (e.g., a power plant) using a digital twin model. Every physical component (turbines, pumps, valves, sensors) is represented as an object in a 3D model. This model serves as the data structure. A user, or an automated system, attaches "labels" to these components. The "data" associated with a label is a time-series data stream from the corresponding physical sensor (e.g., vibration, temperature, pressure). The hierarchy is the physical assembly itself: Plant -> Cooling System -> Primary Loop -> Pump-A3. A user navigates the 3D model, clicks on a component, and can access all labeled sensor data streams associated with it. This allows for random access to operational data based on the physical topology of the plant.

2.2. Nanoscale Molecular Data Tagging

• Enabling Description: A system for organizing data from an Atomic Force Microscope (AFM) or Scanning Tunneling Microscope (STM). As the microscope scans a substrate, it identifies specific molecules or quantum dots. The system assigns a unique identifier ("label") to each feature of interest based on its coordinates (x, y, z). The "data" is the full dataset collected for that feature (e.g., its electronic density of states, molecular bond vibrations). The user can define a hierarchical structure based on spatial regions or functional characteristics, for example: "Substrate-Area-1" -> "Self-Assembled-Monolayer" -> "Molecule-ID-127". This allows a researcher to randomly access the detailed spectral data for any tagged molecule by navigating a spatial or functional hierarchy instead of scrubbing through raw scan data.

Axis 3: Cross-Domain Application

3.1. Aerospace: Flight Anomaly Data Logging

• Enabling Description: An avionics system that records flight parameter data. During flight, the system continuously monitors thousands of parameters. Upon detection of an anomaly (e.g., a sensor reading outside normal limits), the system automatically creates a "data" snapshot of the state of all related systems for the 5-second window around the event. It simultaneously generates a "label" for this data (e.g., "HYD-PRESS-FLAP-A-LOW-20260511T1430Z"). These labels are automatically organized into a pre-defined hierarchy: Flight-ID -> Event-Type (e.g., Hydraulic, Avionics) -> Component -> Timestamped-Label. Post-flight, maintenance engineers can navigate this hierarchy to immediately retrieve the full data packet for a specific anomaly without needing to analyze the entire flight data recorder.

3.2. Agricultural Technology: Genomic Trait Mapping

• Enabling Description: A bioinformatics platform for genetic research. The complete genome of a plant variety is the root of the data structure. A geneticist can create custom, user-defined hierarchies to organize their research. For example, a hierarchy could be "Drought Resistance Traits" -> "Root-System-Efficiency" -> "Gene-XYZ123". The "label" is "Gene-XYZ123". The "data" linked to this label is the full DNA sequence, RNA expression levels from different experiments, and associated research notes. This allows different research teams to build their own custom organizational views on top of the same underlying genomic data, facilitating random access based on functional traits rather than just genomic coordinates.

Axis 4: Integration with Emerging Tech

4.1. AI-Powered Semantic Hierarchy Generation

• Enabling Description: A system where a user inputs raw, unstructured information (voice notes, documents, images). A backend AI pipeline processes the input. For a voice note, it performs speech-to-text, then uses a large language model (LLM) for topic extraction and summarization. The summary becomes the proposed "label". The LLM then analyzes the existing user-defined hierarchy and, based on semantic similarity using vector embeddings, suggests the most logical parent label under which to file the new note. The user is presented with a prompt: "This note is about Q3 budget planning. I suggest filing it under '/Projects/Finance/Budgeting/'. [Confirm] [Change]". Access patterns are monitored to periodically suggest structural optimizations, such as creating a new sub-folder for a frequently accessed topic.

4.2. Blockchain-Verified Data Provenance

• Enabling Description: An information storage system where data integrity and provenance are critical. The "data" chunk is stored on a decentralized file system like IPFS, which generates a content-identifier hash (CID). The user-defined hierarchical structure, composed of human-readable labels, is maintained in a data structure like a Merkle tree. The root hash of this Merkle tree, along with the mapping between a given label and its data's IPFS CID, is stored immutably on a blockchain (e.g., as part of a smart contract's state). To add a new note, a user submits a transaction to the smart contract with the label, its parent in the hierarchy, and the data's CID. To retrieve, a user queries the smart contract for the CID associated with a label and then fetches the data from IPFS. This provides an unchangeable, timestamped audit trail of how information was stored and categorized.

    IPFS-->>User: Return Data Chunk

Axis 5: The "Inverse" or Failure Mode

5.1. Graceful Degradation for Low-Bandwidth Environments

• Enabling Description: A system designed for mobile or edge devices with intermittent network connectivity. The full data chunks are stored in the cloud, but the entire hierarchical label structure is continuously synchronized and cached locally on the device. When the device is offline or on a low-bandwidth connection, the application switches to an "index-only" mode. In this mode, the user can still fully navigate, search, and reorganize their label hierarchy. Attempting to retrieve the data for a selected label will result in a message "Full data unavailable. Connect to a network to access." If a low-resolution thumbnail or a text-only abstract of the data was also cached with the label, that is displayed instead. This preserves the organizational and navigational functionality of the system even when the primary data is inaccessible.

Combination Prior Art with Open-Source Standards

1. Combination with SQLite and FUSE (Filesystem in Userspace):

• Enabling Description: An implementation where the user-defined hierarchy of labels and metadata (including pointers to the actual data files) is stored within a single SQLite database file. This database utilizes a schema with tables for 'labels' (id, parent_id, name) and 'data_links' (label_id, file_path). A background process using the FUSE library reads this SQLite database and presents it to the operating system as a standard, navigable file system. To the user, their custom hierarchy appears as a set of nested folders. Creating a new folder corresponds to adding a new parent label to the database. Adding a file to a folder creates a child label and links it to the file's data. This provides the claimed user-defined random access structure using standard, open-source file system and database tools.

2. Combination with ActivityPub and IPFS:

• Enabling Description: A decentralized knowledge management application. Each user runs a personal server (or a node in a network). Each piece of information ("data") is stored on IPFS. The user organizes CIDs of their data using a local implementation of the '674 patent's labeling system. A user can choose to make a branch of their hierarchy public by publishing it to their followers via the ActivityPub protocol. For example, a user could publish the root label "/My-Blog/Tech-Reviews". Their server would generate an OrderedCollection of activities, one for each sub-label and data item in that branch. Followers' servers would receive this and could reconstruct that portion of the user's hierarchy, allowing them to browse the content using the creator's own organizational structure.

3. Combination with Git and YAML:

• Enabling Description: A system for managing unstructured research data (notes, datasets, models) within a Git repository. The directory structure of the repository forms the basic hierarchy. However, within each directory, a special file named _labels.yml defines more granular, user-friendly labels and their association with specific data files in that directory. The YAML file format allows for defining key-value pairs where the key is the user-defined label (e.g., "Final-Results-Plot") and the value is the filename (e.g., "fig_run3_final_acc.png"). Users can create complex nested structures within the YAML file itself, creating a hierarchy that is independent of the filesystem hierarchy. The entire structure is version-controlled by Git, allowing users to track changes to their organizational schema over time.
