    Study Notes

    Web3

    • Tim Berners-Lee envisioned Web 3.0 as a semantic web enabling shared and reusable linked data across various platforms.
    • Focuses on technology-driven meaning construction and task completion, rather than human interpretation.
    • Coined in 2014 by Gavin Wood, Web3 refers to a decentralized internet powered by blockchain technology.
    • Elon Musk questioned the reality of Web3, labeling it as more of a marketing term than a tangible concept.
    • Berners-Lee disagrees with blockchain-based Web3, stressing user control over personal data through features like:
      • Global single sign-on for universal access.
      • Login IDs for data sharing among users.
      • A universal API for data retrieval across platforms.
    • Transition from Web 2.0 to Web 3.0 is ongoing, with key differences noted:
      • Centralization vs. decentralization.
      • Traditional currency vs. cryptocurrencies.
      • Use of cookies vs. NFTs.
      • Web applications vs. smart applications utilizing AI and machine learning.

    Metaverse

    • The metaverse is envisioned as a shared, immersive 3D virtual space enhancing online human experiences.
    • Comprised of seven layers addressing technology to user experience:
      • Layer 1: Infrastructure.
      • Layer 2: Data management via mobile records.
      • Layer 3: Blockchain for decentralized transactions.
      • Edge computing improves data processing and responsiveness.
      • Layer 4: Spatial computing using Extended Reality (XR).
      • Layers 5-7: Focus on commerce, discovery, and user experience.

    Extended Reality (XR)

    • XR encompasses Augmented Reality (AR), Virtual Reality (VR), Mixed Reality, and upcoming technologies.

    Augmented Reality (AR)

    • AR integrates real-world and digital content, enhancing user experience rather than replacing it.
    • Pokémon Go is a noted AR example, driving foot traffic to businesses.
    • AR applications span various fields, including:
      • Design and construction for product visualization.
      • Manufacturing for remote maintenance assistance.
      • Healthcare for surgical guidance.
    • Edge computing combined with AR enhances access to real-time data and user engagement.

    Virtual Reality (VR)

    • Describes a fully immersive, three-dimensional digital environment for exploration and interaction.
    • Saw increased interest during the COVID-19 pandemic as an alternative meeting platform.
    • Platforms like Virbela offer virtual spaces for meetings with engaging avatar interactions.

    Mixed Reality

    • Combines real and digital worlds that interact in real-time, requiring more processing power and specific headsets like Microsoft's HoloLens.

    Digital Twins

    • A digital twin is a virtual model representing a physical object or system with updates via real-time data.
    • Differentiates from simulations by using continuous updates versus predefined datasets.
    • Widely employed in manufacturing and engineering to monitor and optimize performance.

    Records Management in the Metaverse

    • Records and Information Management (RIM) faces new challenges in capturing content within the metaverse.
    • Organizations should incorporate metaverse-related information into records retention schedules and governance plans.
    • The metaverse economy could contribute $3 trillion globally by 2031, emphasizing the need for thorough record management of digital assets and user interactions.
    • Examples of records in a virtual art gallery include store layout and design, digital assets (NFTs), and transaction data regarding user behavior and purchases.
